Fig. 1 is a schematic view of a charging station according to an embodiment of the present application. As shown in fig. 1, in the present embodiment, the charging station 1 includes a power distribution device 11 and a plurality of charging piles 12-1n, n being 2 or more. At least one charging module 1i1 (i is 2 or more and n or less) is disposed in the charging pile 1 i. Optionally, in this embodiment, the charging module of each charging post is configured with a corresponding charging gun (not shown in fig. 1) to charge the device to be charged through the charging gun.
In this embodiment, two charging modules are included in the charging pile as an example, and it should be understood that the number of charging modules in the charging pile is not limited in this embodiment. Wherein the charging pile 12 includes charging modules 121 and 122. The charging post 13 includes charging modules 131 and 132. The charging stake 1n includes charging modules 1n1 and 1n2.
In an alternative implementation, each charging module has a corresponding power level. It should be appreciated that the power level of each charging module in the charging station is determined based on the application scenario of the charging station, for example, the charging station is used to charge the electric vehicle, and then the power level of each charging module may be determined according to the charging power requirements of the current electric vehicles. For example, the power levels may include 15kw, 20kw, 30kw, 40kw, 45kw, 60kw, 75kw, 80kw, 120kw, and the like.
Optionally, the power levels of the charging modules in the same charging pile are the same, and the power levels of the charging modules in different charging piles may be the same or different. In other alternative implementations, the power levels of the charging modules within the same charging stake may also be different, which is not limited by the present embodiment.
In an alternative implementation, multiple battery modules may be included in the charging module to determine the maximum power (i.e., power class) that it can output. For example, assuming that the power level of the charging module 121 is 60kw, 3 battery modules having an output power of 15kw may be used to assemble the charging module 121.
In an alternative implementation, the power distribution apparatus 11 may communicate with each charging pile in a wired manner (for example, connect to each other through a communication bus to perform communication), so as to receive a charging request (i.e., a power distribution request), and control a corresponding power module to start operation according to a power distribution result. In other alternative implementations, the power distribution apparatus 11 may also communicate with each charging pile in a wireless manner (e.g., based on a network such as a local area network), which is not limited by the present embodiment.
In an alternative implementation, the charging pile 1i further includes a controller 1i2, where i is greater than or equal to 2 and less than or equal to n. Wherein the controller 1i2 is configured to control each charging module 121 in the charging pile 1i to start or stop operation. Alternatively, the power distribution apparatus 11 may communicate with the controllers of the respective charging piles by wired or wireless means.
In this embodiment, the power distribution device 11 is configured to receive a charging request of a device to be charged, perform power distribution according to a power requirement in the charging request and a power class of a selected charging module, determine a target charging module, and control the target charging module to charge the device to be charged. Wherein the total power of the target charging module is adapted to the power demand of the device to be charged.
Taking the device to be charged as an electric automobile as an example, after the electric automobile enters a charging station, a user selects an idle charging gun or automatically selects the idle charging gun through a server so as to charge the electric automobile.
In an alternative implementation, in response to the charging gun establishing an electrical connection with the device to be charged, the charging post corresponding to the charging gun receives a charging request and sends the charging request to the power distribution device.
In another alternative implementation, the user may send the charging request to the charging station through the user terminal, for example, the user scans a two-dimensional code corresponding to a charging post to which the idle charging gun belongs through the user terminal to send the charging request to the charging post, and the charging post sends the charging request to the power distribution device.
In an alternative implementation manner, after the charging pile receives the charging request, in response to the charging module corresponding to the selected charging gun being in a working state, or the charging module corresponding to the selected charging gun being in an idle state, the total power of the available charging modules in the corresponding charging pile is smaller than the power requirement of the equipment to be charged, and the charging pile sends the charging request to the power distribution equipment in a wired or wireless mode to request power distribution.
Alternatively, taking the charging pile 12 in fig. 1 as an example, after the charging gun corresponding to the charging module 121 is electrically connected with the device to be charged, the controller 123 determines the power requirement of the device to be charged and the enabling state of the charging module 121, if the enabling state of the charging module 121 is the idle state and the power level of the charging module 121 meets the power requirement of the device to be charged (for example, the power level of the charging module 121 is 80kw and the power requirement of the device to be charged is 80 kw), the controller 123 controls the charging module 121 to charge the device to be charged.
If the charging module 121 is in an operating state, the controller 123 transmits a charging request to the power distribution apparatus 11 through a wired or wireless manner to request power distribution.
If the enabled state of the charging module 121 is an idle state, the power level of the charging module 121 does not meet the power requirement of the device to be charged (for example, the power level of the charging module 121 is 80kw, and the power requirement of the device to be charged is 160 kw), the controller 123 queries whether the charging module 122 is in the idle state, and if the charging module 122 is in the idle state, the controller 123 controls the charging module 121 and the charging module 122 to charge the device to be charged together. It should be understood that if the number of charging modules in the charging pile is greater than 2, the controller 123 queries other idle charging modules in the charging pile 12, and if other idle charging modules exist in the charging pile 12, the controller 123 controls the charging module 121 to charge the device to be charged together with any other charging module in the charging pile 12. Optionally, the controller 123 controls the charging module 121 to charge the device to be charged together with an idle charging module in the charging pile 12 nearest to the charging module 123.
If the enabled state of the charging module 121 is an idle state, the power level of the charging module 121 does not meet the power requirement of the device to be charged (for example, the power level of the charging module 121 is 80kw, the power requirement of the device to be charged is 200 kw), and no other idle charging modules exist in the charging pile 12 or the total power of the charging module 121 and other idle charging modules in the charging pile 12 does not meet the power requirement of the device to be charged, the controller 123 sends a charging request to the power distribution device 11 in a wired or wireless manner to request power distribution.
In an alternative implementation, after the active state is switched (e.g., from the idle state to the active state, or vice versa), each charging pile sends the switched active state to the power distribution device to facilitate accurate power distribution by the power distribution device 11.
In an alternative implementation, the power distribution device 11 is further configured to determine the first charging module as the target charging module in response to a power demand of the device to be charged adapting to the first charging module (i.e. the charging module connected to the selected charging gun). Optionally, in response to the first charging module being in an idle state, the power distribution device 11 controls the first charging module to charge the device to be charged through the controller of the corresponding charging post, in response to the first charging module being in a working state, that is, the first charging module is charging other devices to be charged through other charging guns (that is, charging guns not having a corresponding relationship with the first charging module), the power distribution device 11 controls the first charging module to be turned off so as to switch to an idle state, that is, disconnect the connection with other charging guns, and redistribute a new charging module for other charging guns, and meanwhile, the controller of the corresponding charging post controls the first charging module to charge the device to be charged. Thus, the power supply efficiency of the charging station can be improved.
In an alternative implementation manner, the power distribution device 11 is further configured to query and obtain at least one second charging module, and determine the first charging module and each second charging module as the target charging module, in response to the maximum power corresponding to the power class of the first charging module not meeting the power requirement of the device to be charged. For example, assuming that the power requirement of the device to be charged is 200kw, but the power class of the first charging module is 80kw, that is, the corresponding maximum output power is 80kw, other idle charging modules need to be queried to meet the power requirement of the device to be charged. Therefore, the charging module corresponding to the selected charging gun can be used for charging the equipment to be charged, and other charging modules can be used for charging the equipment to be charged at the same time, so that the charging requirements of various equipment to be charged can be met.
In an alternative implementation, the power distribution apparatus 11 queries candidate charging modules in an idle state, and determines a second charging module from among the candidate charging modules. Wherein the candidate charging modules are charging modules in the charging station other than the first charging module. Taking the charging station shown in fig. 1 as an example, assuming that the selected first charging module is the charging module 131, the power requirement of the device to be charged is 200kw, the power class of the charging module 131 is 80kw, the idle power modules obtained by query are the charging modules 121, 122, 141 and 142, wherein the power classes of the charging module 121 and the charging module 122 are all 80kw, and the power classes of the charging module 141 and the charging module 142 are all 40kw, the power distribution device 11 can randomly screen one power module from the charging module 121 and the charging module 122, randomly screen one power module from the charging module 141 and the charging module 142, and the power module 131 is used as the target power module, thereby meeting the requirement of the device to be charged. Further alternatively, the power distribution apparatus 11 selects an appropriate power module closest to the charging module 131, that is, determines the charging module 131, the charging module 122, and the charging module 141 as target charging modules.
In another alternative implementation, the power distribution apparatus 11 is configured to sequentially traverse each candidate charging module based on the distance from the first charging module, determine the candidate charging module satisfying the predetermined condition as the second charging module, and stop the traversing in response to the total power of the first charging module and each second charging module adapting to the power demand. Wherein the candidate charging modules are charging modules in the charging station other than the first charging module. Optionally, during the traversal, the candidate charging module in the idle state is determined as the second charging module. Further optionally, in this embodiment, the candidate charging modules in the first charging pile to which the first charging module belongs are traversed first, and if the traversing result still does not meet the power requirement of the device to be charged, the candidate charging modules in the non-first charging pile are traversed in sequence based on the distance between the candidate charging modules and the first charging module.
Taking the charging station shown in fig. 1 as an example, assuming that the selected first charging module is the charging module 131, in response to the power requirement of the device to be charged being greater than the maximum power corresponding to the power class of the charging module 131, the power distribution device 11 first traverses the charging module 132, determines the charging module 132 as the second charging module if it is in an idle state, and determines the charging module 131 and the charging module 132 as the target charging module if the total power of the charging module 131 and the charging module 132 satisfies the power requirement of the device to be charged. Assuming that the charging module 132 is in a working state or the total power of the charging modules 131 and 132 still does not meet the power requirement of the device to be charged, the charging module 122, the charging module 121, the charging module 141, and the like are sequentially traversed until the obtained total power of the second charging module and the first charging module meets the power requirement of the device to be charged. Alternatively, the distance from the first charging module may be traversed in a left-right-front manner, that is, the left side of the first charging module is traversed first and then the right side of the first charging module is traversed under the same distance, or the distance from the first charging module may be traversed in a right-left-front manner. It should be understood that, since the arrangement manners of the charging piles in the specific application scenario are different, the embodiment does not limit the traversing manner.
In an alternative implementation, after the power distribution device 11 traverses all the candidate charging modules, the total power of the first charging module and the obtained second charging module still does not meet the power requirement of the device to be charged, and then the candidate charging modules are traversed again after waiting for a predetermined time (for example, 1-10 minutes) to query for obtaining at least one second candidate charging module. That is, the total power of the charging modules currently in the idle state cannot meet the power requirement of the device to be charged, and then the waiting for a predetermined time is needed, that is, the charging modules currently in the working state are switched to the idle state, and then the traversing is performed to query and obtain the second charging module.
In this embodiment, the power distribution apparatus 11 further includes a housing. The material and process of the housing may be any available material and process that allows the housing to meet a predetermined protection level. Optionally, the predetermined protection level may be IP54, so as to avoid the damage caused by the environmental impact of the power distribution apparatus 11.
According to the embodiment of the application, the power distribution is carried out according to the power requirement of the equipment to be charged and the power grade of the selected first charging module, the target charging module is determined, and the target charging module is further controlled to charge the equipment to be charged, wherein the total power of the target charging module is adapted to the power requirement. That is, according to the embodiment of the application, the target charging module is distributed to the equipment to be charged according to the power requirement of the equipment to be charged, so that the charging requirements of various kinds of equipment to be charged can be met, and meanwhile, the power supply efficiency of the charging station can be improved.
Fig. 2 is a schematic view of another charging station according to an embodiment of the application. In this embodiment, the power distribution device communicates with each charging pile in a wired manner, and controls each charging module to charge the device to be charged.
As shown in fig. 2, in the present embodiment, the charging station 2 includes a power distribution device 21 and a plurality of charging piles 22-2n, n being equal to or greater than 2.
The charging pile 1i is provided with a corresponding controller 2i3 and two charging modules 2i1 and 2i2 (i is greater than or equal to 2 and less than or equal to n). The charging modules 2i1 and 2i2 are configured with corresponding charging guns 2i1 'and 2i2' to charge the device to be charged through the charging guns.
In the present embodiment, the power distribution apparatus 21 includes a controller 211 and a control circuit 212. The controller 211 communicates with the controllers 2i3 of the respective charging piles via a communication bus can. The control circuit 212 is controlled by the controller 211 to control the target charging module to charge the device to be charged. The target charging module comprises at least one charging module, and the total power of the target charging module is matched with the power requirement of equipment to be charged.
The control circuit 212 includes a plurality of first switching elements k11-k1n, k21-k2n and a plurality of second switching elements kk1-kkN. Each charging module is provided with a corresponding first switching element, and a corresponding second switching element is arranged between two charging piles. The controller 211 is configured to control the corresponding first and second switching elements to be closed to control the target charging module to charge the device to be charged.
In this embodiment, as shown in fig. 2, the first ends of the first switching elements are respectively connected to the output ends of the corresponding charging modules. The second ends of the first switch elements corresponding to the same charging pile are connected to the common end. The second switching element is connected between the corresponding common terminals of the two charging piles. For example, the first end a21 of the first switching element k21 is connected to the output terminal of the corresponding charging module 221, the first end a22 of the first switching element k22 is connected to the output terminal of the corresponding charging module 222, and the second ends of the first switching element k21 and the first switching element k22 corresponding to the charging pile 22 are connected to the common end a23. The second switching element kk1 is connected between the common terminal a23 corresponding to the charging pile 22 and the charging pile 23. Optionally, in this embodiment, a second switching element is connected between the common ends corresponding to any two charging piles in the charging station 2.
In this embodiment, the controller 211 is configured to receive a charging request of a device to be charged, perform power distribution according to a power requirement in the charging request and a power class of a selected charging module, determine a target charging module, and control the target charging module to charge the device to be charged by controlling the first switching element and the second switching element.
Alternatively, taking the selected charging gun as the charging gun 231', the charging using the charging station 2 may have the following cases:
1. the controller 233 controls the charging stake 23 to charge the device to be charged.
(11) The controller 233 determines that the charging module 231 corresponding to the charging gun 231' is in an idle state, and the power level of the charging module 231 corresponding to the charging gun 231' meets the power requirement of the device to be charged, and then controls the charging module 231 to charge the device to be charged through the charging gun 231 '.
(12) The controller 233 determines that the charging module 231 corresponding to the charging gun 231 'is in an idle state and the power level of the charging module 231 corresponding to the charging gun 231' does not meet the power requirement of the device to be charged, then determines that the charging module 232 in the charging pile 23 is in an idle state and the total power of the charging module 231 and the charging module 232 meets the power requirement of the device to be charged, and controls the switch k between the charging module 231 and the charging module 232 to be closed so that the charging module 231 and the charging module 232 jointly charge the device to be charged.
2. The power distribution device 21 determines a target charging module and controls the target charging module to charge the device to be charged.
(21) The controller 233 determines that the charging module 231 corresponding to the charging gun 231 'is in an idle state, and the power level of the charging module 231 corresponding to the charging gun 231' does not meet the power requirement of the device to be charged, then determines that the charging module 232 in the charging pile 23 is in an operating state, or determines that the charging module 232 in the charging pile 23 is in an idle state but the total power of the charging module 231 and the charging module 232 does not meet the power requirement of the device to be charged, and then sends a power distribution request to the controller 211 in the power distribution device 21 through the communication bus can. The controller 211 sequentially traverses each charging module 232, 222, 221, 241, etc. according to the distance from the charging module 231 until the total power of the traversed charging module in an idle state and the charging module 231 meets the power requirement of the device to be charged. Assuming that the target charging modules determined through the traversal are the charging modules 231, 232, 221, the controller 211 controls the first switching element k21, the first switching element k31, the second switching element kk1, and the switch k to be closed to control the charging module 231, the charging modules 232, and 221 to simultaneously charge the device to be charged.

Fig. 3 is a flow chart of a power allocation method according to an embodiment of the present application. As shown in fig. 3, the power allocation method according to the embodiment of the present application includes the following steps:
step S110, in response to a charging request of a device to be charged, determining a power requirement of the device to be charged. In an alternative implementation, the charging requirements of the device to be charged may be sent to the device to be charged by the controller of the selected charging stake. Optionally, when the charging gun and the device to be charged are electrically connected, the charging pile corresponding to the charging gun receives a charging request and sends the charging request to the power distribution device; or the user can send a charging request to the charging station through the user terminal, for example, the user scans a two-dimensional code corresponding to a charging pile to which the idle charging gun belongs through the user terminal to send the charging request to the charging pile, and the charging pile sends the charging request to the power distribution equipment; or after the charging pile receives the charging request, responding to the charging module corresponding to the selected charging gun to be in a working state, or responding to the charging module corresponding to the selected charging gun to be in an idle state, wherein the total power of the available charging modules in the corresponding charging pile is smaller than the power requirement of the equipment to be charged, and the charging pile sends the charging request to the power distribution equipment in a wired or wireless mode so as to request power distribution. It should be understood that the present embodiment does not limit the process of receiving the charge request.
Step S120, power distribution is performed according to the power requirement of the equipment to be charged and the power class of the selected first charging module, and the target charging module is determined. Wherein the total power of the target charging module is adapted to the power demand.
In an alternative implementation, step S120 may specifically include: and determining the first charging module as a target charging module in response to the power requirement of the device to be charged being compatible with the power class of the first charging module. In an alternative implementation manner, the power allocation method of the present embodiment further includes: and responding to the first charging module in a working state, and controlling the first charging module to be closed so that the selected first charging module can charge the equipment to be charged.
Fig. 4 is a flowchart of a method for determining a target charging module according to an embodiment of the present application. In another alternative implementation, as shown in fig. 4, step S120 may specifically include the following steps:
step S121, in response to the maximum power corresponding to the power level of the first charging module not meeting the power requirement of the device to be charged, at least one second charging module is queried and obtained.
In an alternative implementation, step S212 may specifically include: and inquiring the candidate charging modules in the idle state, and determining a second charging module from the candidate charging modules. Wherein the candidate charging modules are charging modules in the charging station other than the first charging module. Alternatively, the charging module that meets the condition may be arbitrarily selected from the candidate charging modules in the idle state to determine the second charging module, or the charging module that meets the condition may be selected based on the distance from the first charging module to determine the second charging module, which is not limited in this embodiment.
Fig. 5 is a flowchart of a method for determining a second charging module according to an embodiment of the present application. In another alternative implementation, as shown in fig. 5, step S212 may specifically include the following steps:
step S212a: a candidate charging module for the current traversal is determined based on the distance from the first charging module. Optionally, because the control manner in which the plurality of charging modules in the same charging pile simultaneously charges the device to be charged is simplest, in this embodiment, the candidate charging module traversed for the first time may be another candidate charging module in the first charging pile to which the first charging module belongs, and then sequentially traverse the candidate charging modules in the non-first charging pile based on the distance between the candidate charging modules and the first charging module.
Step S212b: it is determined whether the candidate charging module currently being traversed is in an idle state. If the currently traversed candidate charging module is in the idle state, step S212c is executed. If the currently traversed candidate charging module is not in the idle state, i.e. in the working state, step S212a is executed.
Step S212c: and determining the currently traversed candidate charging module as the second charging module in response to the currently traversed candidate charging module being in an idle state.
Step S212d: determining whether the total power of the first charging module and each second charging module is greater than or equal to the power requirement of the equipment to be charged. If the total power of the first charging module and each second charging module is greater than or equal to the power requirement of the device to be charged, step S212f is performed. If the total power of the first charging module and each second charging module is smaller than the power requirement of the device to be charged, step S212a is performed.
Step S212e: and outputting the second charging module determined by traversal in response to the total power of the first charging module and each second charging module being greater than or equal to the power requirement of the equipment to be charged.
According to the method, the second charging module is determined by traversing each candidate charging module in sequence based on the distance between the second charging module and the first charging module, the efficiency of determining the second charging module can be improved, the second charging module is enabled to be closer to the first charging module, and therefore the logic for controlling the second charging module to charge the equipment to be charged together is simpler.
In an alternative implementation, if the second charging module with the total power greater than or equal to the power requirement of the device to be charged cannot be obtained based on the steps S212a-S2212e, after waiting for a predetermined time, the steps S212a-S2212e are re-executed to obtain the second charging module meeting the condition. Since there is a case where the charging is completed during the waiting time so that some of the charging modules are switched to the idle state, steps S212a-S2212e may be re-performed after waiting for a predetermined time.
Step S122, determining the first charging module and each second charging module as a target charging module.
In this embodiment, the power requirements of the to-be-charged device are not met by the maximum power corresponding to the power level of the first charging module, at least one second charging module is queried and obtained, the first charging module and each second charging module are determined to be target charging modules, and each target charging module is controlled to charge the to-be-charged device at the same time, so that the charging requirements of various to-be-charged devices can be met, and meanwhile, the power supply efficiency of the charging station can be improved.
