The method and the device are mainly applied to the scene of wireless charging of the vehicle, the pure electric vehicle is more and more popular in the future, the convenience of charging can be greatly improved by wireless charging, and very good user experience is achieved. According to different vehicle type designs, a wireless receiving RX coil (i.e. an electric energy receiving coil) on a vehicle may be placed at the front end, the middle part or the rear end of a vehicle chassis, as shown in fig. 1, an A-type vehicle places the RX coil at the front end of the vehicle chassis, a B-type vehicle places the RX coil at the middle part of the vehicle chassis, and a C-type vehicle places the RX coil at the rear end of the vehicle chassis, however, a wireless transmitting TX coil (electric energy transmitting coil) arranged on a parking space may be located at any position of the parking space, if accurate alignment of the RX coil and the TX coil is to be realized, a user is required to continuously adjust the parking position according to the RX coil position of the vehicle and the TX coil position of the parking space until the two positions are successfully matched, which can certainly increase the operation complexity of parking of the user and greatly affect the degree of freedom of parking.
In order to solve the above-mentioned problems, the present disclosure provides a wireless charging method, system and storage medium, the method may be applied to a charging device disposed in a preset place, the charging device includes one or more movable electric energy transmitting coils and a coil array disposed in the preset place, the coil array includes a plurality of induction coils, the preset place includes one or more preset parking spaces, when a vehicle to be charged parks in a target parking space (a parking space where the vehicle to be charged is currently parked in a plurality of preset parking spaces), the charging device disposed in the preset place may position an electric energy receiving coil disposed on the vehicle to be charged through a plurality of induction coils of the coil array, so as to obtain a target position of the electric energy receiving coil, and after the target electric energy transmitting coil disposed in the preset place is moved to the target position, realize alignment of the two coils so as to wirelessly charge the vehicle to be charged through the target electric energy transmitting coil and the electric energy receiving coil, thus avoiding a need of continuously adjusting a parking position of the vehicle to be charged to realize accurate alignment of the target electric energy transmitting coil and the electric energy receiving coil, thereby reducing a parking operation complexity of a driver and improving a parking operation freedom of the vehicle.
The following detailed description of specific embodiments of the present disclosure refers to the accompanying drawings.
Fig. 2 is a flowchart illustrating a wireless charging method according to an exemplary embodiment, which may be applied to a charging device arranged at a preset location, which may be, for example, a parking lot, the charging device including one or more movable power transmitting coils (e.g., TX coils) and a coil array arranged at the preset location, which includes one or more preset parking spaces, the coil array including a plurality of induction coils for locating a power receiving coil of a vehicle to be charged, as shown in fig. 3a, may be arranged at the preset location, which is provided with one or more movable power transmitting coils (e.g., TX coils), as shown in fig. 3 b.
As shown in fig. 2, the wireless charging method includes the steps of:
in step S21, in the case of receiving a charging request message sent by a vehicle to be charged, a target parking space for the vehicle to be charged to park is determined.
In an actual application scenario, after a vehicle to be charged is parked in a target parking space, the vehicle to be charged can communicate with a charging device of the parking space, and the vehicle to be charged can send the charging request message to the charging device according to own battery parameters (such as parameters of battery State of Charge (SOC), battery allowed chargeable power and the like).
In this step, the charging device may determine the target parking space according to the set detection device (such as an infrared sensing device), or the vehicle to be charged may determine the target parking space of the current parking based on the sensor signal, and then send the parking space identification information of the target parking space to the charging device through the charging request message, so that the charging device may determine the target parking space through the parking space identification information in the charging request message.
In step S22, a target induction coil corresponding to the target parking space is determined from the coil array.
In a possible implementation manner, the charging device may determine, according to the position information of each induction coil in the coil array, that the induction coil located in the target parking space is the target induction coil.
In step S23, the target induction coil is used to locate the electric energy receiving coil disposed on the vehicle to be charged, so as to obtain the target position of the electric energy receiving coil.
In this step, after the target induction coils are energized, a first electric energy induction parameter of each target induction coil is obtained, and a position where the target induction coil with the maximum first electric energy induction parameter is located is determined as the target position of the electric energy receiving coil.
The first power sensing parameter may include a sensing voltage or a sensing current.
It will be appreciated that if one of the target induction coils is successfully aligned with the power receiving coil, the power receiving coil may be regarded as a load corresponding to the target induction coil, for example, the induction voltage of the target induction coil may be the highest, and other induction coils that are not successfully aligned with the power receiving coil are in an idle state, and the corresponding induction voltage is 0 or less, so that in this step, the position of the target induction coil with the largest induction voltage may be determined as the target position of the power receiving coil.
In step S24, any idle power transmitting coil located at the preset location is used as a target power transmitting coil, and the target power transmitting coil is moved to the target position, so that the vehicle to be charged is wirelessly charged through the target power transmitting coil and the power receiving coil.
In a possible implementation manner, the target power transmitting coil can be controlled to move to the target position by any mechanical device, for example, the parking space Tx coil of the parking space can be moved to be above the target induction coil, and matching with the Rx coil is completed.
It should be noted that, the induction coil is usually placed below the power transmitting coil, otherwise, the charging efficiency is affected during wireless charging; in addition, when the induction coil is used for positioning the electric energy receiving coil, the electric energy transmitting coil above the induction coil needs to be moved to other positions, otherwise, the positioning accuracy is affected.
In addition, the step can realize wireless charging of the vehicle to be charged through the target electric energy transmitting coil and the electric energy receiving coil by the following steps:
the method comprises the steps that charging parameters are sent to a vehicle to be charged, the charging parameters comprise a plurality of charging power gears and maximum output capacity corresponding to each charging power gear, the maximum output capacity can comprise parameters such as maximum output power, maximum output voltage and maximum output current, charging indication information sent by the vehicle to be charged is received, and the charging indication information comprises target power gears determined by the vehicle to be charged from the plurality of charging power gears according to battery parameters and the maximum output capacity; and transmitting electric energy to the electric energy receiving coil through the target electric energy transmitting coil according to the transmission capacity corresponding to the target power gear.
In addition, in another possible implementation manner of the present disclosure, the induction coil may also be used as a power transmitting coil to transmit power to a power receiving coil on a vehicle to realize a wireless charging function of the vehicle, that is, at least one target induction coil may be used as the target power transmitting coil to wirelessly charge the vehicle to be charged through at least one of the target induction coil and the power receiving coil.
It should be further noted that, in particular, the need for several target induction coils to wirelessly charge the vehicle to be charged generally depends on the size of the target induction coils and the size of the power receiving coil on the vehicle, for example, if the power receiving coil has a size of 100cm x 100cm and the target induction coil has a size of 10cm x 10cm, then 10 target induction coils are generally required to achieve wireless charging of the vehicle, which is only illustrated herein and not limited by the present disclosure.
It should be noted that the shape of the coil (including the power transmitting coil, the power receiving coil, and the induction coil) in the present disclosure is not limited, and may be, for example, circular, square, rectangular, or the like.
By adopting the method, after the vehicle to be charged is parked in the target parking space, the charging device arranged in the preset place can position the electric energy receiving coil arranged on the vehicle to be charged through the plurality of induction coils of the coil array to obtain the target position of the electric energy receiving coil, and the target electric energy transmitting coil positioned in the preset place is moved to the target position to realize the alignment of the two coils so as to wirelessly charge the vehicle to be charged through the target electric energy transmitting coil and the electric energy receiving coil, thereby avoiding the need of continuously adjusting the parking position of the vehicle to be charged to realize the accurate alignment of the target electric energy transmitting coil and the electric energy receiving coil, reducing the parking operation complexity of a driver and improving the parking degree of freedom of the vehicle.
In the actual wireless charging scene, if foreign matters (such as metal, living body and the like) exist between the target electric energy transmitting coil and the electric energy receiving coil, the charging efficiency of the vehicle is affected, and even potential safety hazards exist, therefore, before the vehicle to be charged is wirelessly charged through the target electric energy transmitting coil and the electric energy receiving coil, whether the foreign matters exist between the two coils can be detected, and under the condition that the foreign matters do not exist between the target electric energy transmitting coil and the electric energy receiving coil, the vehicle to be charged is wirelessly charged through the target electric energy transmitting coil and the electric energy receiving coil.
Specifically, whether a foreign object exists between the two coils can be detected by:
the quality factor Q value corresponding to the target electric energy transmitting coil can be obtained; if the Q value is within the preset value range, determining that no foreign matter exists between the target electric energy transmitting coil and the electric energy receiving coil.
If the Q value is within the preset numerical range, it can be determined that no foreign matter exists between the target power transmitting coil and the power receiving coil, but if the Q value is outside the preset numerical range, it is indicated that the foreign matter exists between the two coils, an alarm prompt is needed, or an indication message is sent out, so that related personnel can remove the foreign matter between the two coils according to the indication message, the wireless charging efficiency is ensured, and meanwhile, potential safety hazards are avoided.
The above description can be through arranging the coil array in the parking area, realize the location of the electric energy receiving coil on the vehicle that waits to charge through a plurality of induction coils of this coil array, obtain the target position of electric energy receiving coil, afterwards can remove the movable electric energy transmitting coil in the parking area to this target position and realize the counterpoint of two coils, perhaps directly use this induction coil as electric energy transmitting coil and the electric energy receiving coil of vehicle counterpoint, avoided the driver to need constantly adjust the parking position of waiting to charge the vehicle to realize the complex operation of accurate counterpoint of target electric energy transmitting coil and electric energy receiving coil like this.
In another possible implementation manner, in order to improve the parking degree of freedom of the vehicle and improve the alignment efficiency of the electric energy transmitting coil and the electric energy receiving coil when the vehicle is wirelessly charged, the present disclosure may further preset a plurality of electric energy transmitting coils on each preset parking space, and different electric energy transmitting coils are set at different positions of the preset parking space, for example, one available electric energy transmitting coil may be respectively placed in front, in and behind the parking space, so that the wireless charging of the vehicle may be achieved by:
Fig. 4 is a flowchart illustrating a wireless charging method according to an exemplary embodiment, as shown in fig. 4, including the steps of:
in step S41, the charging device determines an available power transmitting coil set on a target parking space when receiving a charging request message sent by the vehicle to be charged, where the target parking space is a parking space where the vehicle to be charged is currently parked in a plurality of preset parking spaces.
In an actual application scene, after a vehicle to be charged is driven into a target parking space for parking, the vehicle to be charged can communicate with a charging device of the parking space, the vehicle to be charged can send the charging request message to the charging device according to own battery parameters (such as battery State of Charge (SOC), battery allowed chargeable power and the like), and the charging device can determine the number of available electric energy transmitting coils and coils arranged on the target parking space under the condition of receiving the charging request message, and then can send the number of coils of the available electric energy transmitting coils arranged on the target parking space to the vehicle to be charged.
The target parking space of the current parking can be determined by the vehicle to be charged based on the sensor signal, then the parking space identification information of the target parking space is sent to the charging device through the charging request message, and the target parking space can also be determined by the charging device according to the set detection equipment, which is not limited in the disclosure.
In step S42, when a plurality of available power transmitting coils are disposed on the target parking space, a second power induction parameter of the power receiving coil is obtained through the vehicle to be charged.
The second electric energy induction parameter comprises parameters such as transmission power or transmission current.
In this step, the vehicle to be charged may determine the alignment strategy of the next transmitting coil and receiving coil based on the number of coils of the available power transmitting coils located on the target parking space sent by the charging device.
In the present disclosure, when a plurality of available electric energy transmitting coils are disposed on the target parking space, a coarse adjustment alignment strategy may be adopted to determine the target electric energy transmitting coil matched with the electric energy receiving coil from the plurality of available electric energy transmitting coils, and after the vehicle to be charged is driven into the target parking space, the electric energy receiving coil disposed on the vehicle to be charged and the available electric energy transmitting coil disposed on the target parking space are subjected to energy matching, specifically, whether the matching is successful or not may be determined according to the value of the second electric energy induction parameter of the electric energy receiving coil.
In step S43, if the second electric energy induction parameter is greater than or equal to the preset threshold, the vehicle to be charged is wirelessly charged through a target electric energy transmitting coil and the electric energy receiving coil, where the target electric energy transmitting coil is an electric energy transmitting coil with the highest second electric energy induction parameter with the electric energy receiving coil among the plurality of available electric energy transmitting coils.
It will be appreciated that the target power transmitting coil is generally referred to as the available power transmitting coil that is located closest to the power receiving coil in a coarse alignment strategy.
Under the condition that the second electric energy induction parameter is larger than or equal to a preset threshold value, the current matched target electric energy transmitting coil can be determined to transmit electric energy meeting the charging requirement to the vehicle, and therefore, the matching of the coils can be achieved through arranging a plurality of electric energy transmitting coils on each preset parking space, and the parking mode of the vehicle can be achieved regardless of the type of the vehicle, and the parking degree of freedom of the vehicle is improved.
The actual value of the preset threshold may be specifically set according to the charging requirement, for example, may be set to 70% of the power matching capability.
For example, it is assumed that an electric energy transmitting coil is placed at each of the front, middle and rear positions of the target parking space, that is, an a coil disposed in front of the target parking space, a b coil disposed in the middle of the target parking space, and a c coil disposed in rear of the target parking space, if the vehicle to be charged is a vehicle with a receiving coil disposed at the front end of the vehicle, the electric energy receiving coil on the vehicle may be automatically matched with the a coil on the target parking space after the vehicle is parked in the target parking space, if the vehicle to be charged is a vehicle with a receiving coil disposed in the middle of the vehicle, the electric energy receiving coil on the vehicle may be automatically matched with the b coil on the target parking space after the vehicle is parked in the rear end of the vehicle, and further, the electric energy receiving coil on the vehicle to be charged may be automatically matched with the c coil on the target parking space based on the electric energy transmitting coil and the electric energy receiving coil obtained by matching.
By adopting the method, a plurality of available electric energy transmitting coils are preset on each preset parking space, different available electric energy transmitting coils are arranged at different positions of the preset parking spaces, for example, one available electric energy transmitting coil can be respectively arranged in front of, in middle of and behind the parking space, thus, after a vehicle to be charged is parked in a target parking space (a parking space where the vehicle to be charged is currently parked in a plurality of preset parking spaces), an electric energy receiving coil on the vehicle can be easily matched with the target electric energy transmitting coil with consistent positions from the plurality of available electric energy transmitting coils on the target parking space, the vehicle to be charged acquires a second electric energy induction parameter of the electric energy receiving coil, and under the condition that the second electric energy induction parameter is larger than or equal to a preset threshold value, the vehicle to be charged is subjected to wireless charging through the target electric energy transmitting coil and the electric energy receiving coil, so that the parking operation complexity of a driver can be reduced, and the parking degree of freedom of the vehicle is improved.
It can be understood that in an actual wireless charging scenario, the "fine adjustment" scheme may be further turned on, i.e. the coil alignment adjustment is performed based on the wireless charging method shown in fig. 5, when the coils cannot be properly matched due to different sizes of some vehicle models or the user parking is askew, i.e. the target power transmitting coil cannot be obtained based on the coarse adjustment of the coil alignment strategy (i.e. the second power sensing parameter of the acquired power receiving coil is smaller than the preset threshold).
Fig. 5 is a flowchart of a wireless charging method according to the embodiment shown in fig. 4, and as shown in fig. 5, the method further includes:
in step S44, the vehicle to be charged receives the coil identification of the target power transmitting coil sent by the charging device.
In one possible implementation manner, the charging device may obtain electric energy output parameters (such as output power, output current, etc.) corresponding to a plurality of available electric energy transmitting coils located on the target parking space, and use the transmitting coil with the largest electric energy output parameter as the target electric energy transmitting coil.
In step S45, under the condition that the second electric energy sensing parameter is smaller than the preset threshold, triggering the position automatic adjustment strategy of the vehicle to be charged until the second electric energy sensing parameter is increased to the preset threshold, and after the second electric energy sensing parameter is increased to the preset threshold, wirelessly charging the vehicle to be charged through the target electric energy transmitting coil and the electric energy receiving coil.
The automatic position adjustment strategy may here include either of the following two ways:
in a first mode, the vehicle to be charged receives a positioning map of the target parking space sent by the charging device and a first position of the target electric energy transmitting coil in the positioning map; determining a second position of the power receiving coil in the positioning map; determining a parking path based on the first location and the second location; and adjusting the parking position of the vehicle to be charged according to the parking path, and judging whether the second electric energy induction parameter is larger than or equal to the preset threshold value in real time.
The parking path may be determined based on an implementation of automatic parking based on a position error as described in the related literature, which is not limited by the present disclosure.
The second mode is that after the parking position of the vehicle to be charged is adjusted according to the first preset path, the change trend of the second electric energy induction parameter of the electric energy receiving coil is determined; if the difference value between the value of the second electric energy induction parameter and the preset threshold value is smaller according to the change trend, continuously adjusting the parking position of the vehicle to be charged according to a second preset path with the same direction as the first preset path until the value of the second electric energy induction parameter is increased to the preset threshold value; and if the difference value between the value of the second electric energy induction parameter and the preset threshold value is determined to be larger according to the change trend, continuously adjusting the parking position of the vehicle to be charged according to a third preset path with the opposite direction to the first preset path until the second electric energy induction parameter is increased to the preset threshold value.
For example, the first preset path may be a preset distance (e.g. 50 cm) for controlling the vehicle to travel in front of the vehicle, after the parking position of the vehicle to be charged is adjusted according to the first preset path, a second electric energy sensing parameter of the electric energy receiving coil is obtained, and whether the value of the second electric energy sensing parameter increases (i.e. whether the difference between the value of the second electric energy sensing parameter and the preset threshold value is smaller or not is determined), and if it is determined that the value of the second electric energy sensing parameter increases, the vehicle may be controlled to continuously adjust the parking position of the vehicle to be charged according to a second preset path in the same direction as the first preset path, for example, the vehicle may be controlled to continuously travel in front of the vehicle for 50 cm, during the adjustment of the parking position, the difference between the second electric energy sensing parameter of the electric energy receiving coil obtained in real time and the preset threshold value may be continuously determined, and when the second electric energy sensing parameter increases to the preset threshold value, the adjustment of the parking position of the vehicle may be stopped; conversely, after the vehicle is controlled to adjust the parking position of the vehicle to be charged according to the first preset path, if it is determined that the value of the second electric energy sensing parameter decreases, the vehicle may be controlled to continuously adjust the parking position of the vehicle to be charged according to a third preset path opposite to the first preset path, for example, the vehicle may be controlled to reverse for 1 meter directly behind, the second electric energy sensing parameter of the electric energy receiving coil may be obtained in real time, and meanwhile, whether the trend of change of the second electric energy sensing parameter is increased is determined, and so on, until it is determined that the second electric energy sensing parameter obtained in real time is increased to the preset threshold, the adjustment of the parking position of the vehicle may be stopped.
Therefore, under the condition that a plurality of electric energy transmitting coils are arranged on the target parking space, if the successful matching of the two coils cannot be realized based on the rough adjustment coil alignment strategy, a fine adjustment strategy based on the position automatic adjustment strategy can be started, the parking degree of freedom is ensured, and meanwhile, the success rate and the efficiency of the coil matching during the wireless charging of the vehicle are improved.
For the situation that only one available power transmitting coil is disposed on each preset parking space of the parking lot in an actual application scenario, in order to improve the parking degree of freedom before wireless charging of the vehicle, in another possible implementation manner of the present disclosure, as shown in fig. 6, the power receiving coil on the vehicle may be disposed as a movable coil, for example, a movable range and a specific moving path of the power receiving coil may be preset on a chassis of the vehicle, and on the premise of such a hardware configuration, wireless charging of the vehicle may be implemented by a method as shown in fig. 7.
Fig. 7 is a flow chart illustrating a wireless charging method according to an exemplary embodiment, as shown in fig. 7, the method comprising the steps of:
in step S71, if an available power transmitting coil is disposed on the target parking space, the charging device sends a third position of the available power transmitting coil on the target parking space to the vehicle to be charged.
In step S72, the vehicle to be charged adjusts the position of the power receiving coil according to the third position, and acquires the second power induction parameter of the power receiving coil in real time.
In this step, the vehicle to be charged may adjust the electric energy receiving coil to the third position according to a preset movement path, so as to achieve accurate alignment of the available electric energy transmitting coil and the electric energy receiving coil on the target parking space.
In step S73, if the second power induction parameter is greater than or equal to the preset threshold, the power receiving coil is stopped moving, and the vehicle to be charged is wirelessly charged through the power receiving coil and the available power transmitting coil on the target parking space.
Similarly, in this embodiment, whether the two coils are aligned successfully is also determined based on the magnitude relation between the value of the second power induction parameter of the power receiving coil and the preset threshold value obtained in real time.
Considering that the movable range of the movable power receiving coil located on the vehicle chassis is limited in practical application, the position matching of the two coils may still not be achieved by controlling the position movement of the power receiving coil, so in another possible implementation of the present disclosure, the position matching of the coils may also be achieved in a manner as shown in fig. 8.
Fig. 8 is a flowchart of a wireless charging method according to the embodiment shown in fig. 7, and as shown in fig. 8, the method further includes the steps of:
in step S74, a timer is started, the timer being used for recording an adjustment duration for adjusting the position of the power receiving coil according to the third position of the vehicle to be charged.
In step S75, if the adjustment duration is increased to the preset time threshold, the position automatic adjustment strategy of the vehicle to be charged is triggered until the second power sensing parameter is increased to the preset threshold if the second power sensing parameter is still smaller than the preset threshold.
The automatic position adjustment strategy in this step is described in the embodiment shown in fig. 5, and will not be described here.
In order to further improve the parking degree of freedom before the wireless charging of the vehicle, in another possible implementation manner of the present disclosure, the vehicle to be charged may further adjust the position of the power receiving coil according to the third position, and trigger the position automatic adjustment strategy until the second power sensing parameter increases to the preset threshold.
That is, the vehicle starts the automatic parking function of the vehicle while adjusting the position of the own Rx coil, so that it is possible to achieve high-degree-of-freedom coil position matching, and to rapidly complete coil alignment and charging.
