Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a charging control method for an electric vehicle according to an embodiment of the present invention, the charging control method includes:
step S11: when the target electric automobile is charged, detecting target charging power required by the target electric automobile;
step S12: judging whether the target charging power is larger than the maximum output power of the host;
in this embodiment, in order to improve user experience of a user in a process of using an electric vehicle charging control system, a charging control method for an electric vehicle is provided, so that the electric vehicle charging control system can charge a target electric vehicle even when charging power required by the target electric vehicle is greater than maximum output power of a host in the electric vehicle charging control system.
Specifically, in the present embodiment, a description is given of a host in an electric vehicle charging control system as an execution subject. When the target electric vehicle is charged, firstly, the host in the electric vehicle charging control system detects the target charging power required by the target electric vehicle, that is, the host is used for detecting the charging power required by the target electric vehicle.
It is understood that, in practical applications, a BMS (battery management System) is usually configured in the target electric vehicle, so that when the host and the BMS in the target electric vehicle establish a communication connection, the host can detect the target charging power required by the target electric vehicle through the BMS in the target electric vehicle.
When the host detects the target charging power required by the target electric vehicle, whether the target charging power of the target electric vehicle is larger than the maximum output power of the host is judged, namely, whether the host can charge the target electric vehicle alone is judged. Specifically, if the target charging power required by the target electric vehicle is less than or equal to the maximum output power of the host machine, the target electric vehicle may be charged by using the host machine, and if the target charging power required by the target electric vehicle is greater than the maximum output power of the host machine, the target electric vehicle may not be charged by using the host machine alone.
Step S13: if so, sending a control instruction to a slave machine which is added into the charging control system of the electric automobile in advance so as to enable the slave machine to control a target power output device to output a target power difference value;
the target power output device is a power output device which is added to the electric automobile charging control system in advance; the target power difference is the difference between the target charging power and the maximum output power of the host;
step S14: and outputting the maximum output power of the host machine to the target electric automobile so as to charge the target electric automobile by using the host machine and the slave machine together.
If the target charging power of the target electric vehicle is greater than the maximum output power of the master machine, it indicates that the master machine cannot charge the target electric vehicle, and in this case, the slave machine and the master machine which are added to the electric vehicle charging control system in advance need to be used together to charge the target electric vehicle.
Referring to fig. 2, fig. 2 is a structural diagram of a charging control system of an electric vehicle, when a target charging power of a target electric vehicle is greater than a maximum output power of a master, the master sends a control command to a slave pre-added to the charging control system of the electric vehicle, so that the slave can control a target power output device pre-added to the charging control system of the electric vehicle to output a target power difference, that is, control the power output device to output the target charging power of the target electric vehicle and the maximum output power of the master. Note that, in the present embodiment, the target power output device is a power output device that is added to the electric vehicle charging control system in advance, such as: rechargeable batteries, lithium batteries, and the like.
Obviously, when the slave machine controls the target power output device to output the target power difference, the master machine outputs the maximum output power of the master machine to the target electric vehicle, and at this time, the master machine and the slave machine can output the target charging power required by the target electric vehicle to the target electric vehicle together. Under the condition, the phenomenon that the electric automobile charging control system cannot charge the target electric automobile can be avoided, and therefore the user experience of the user in the process of using the electric automobile charging control system can be further improved.
In addition, in practical application, the master and the slave in the electric vehicle charging control system can be detachably connected, that is, the master in the electric vehicle charging control system can be used alone or together with the slave.
At this time, if the user only needs the dc charger with a relatively low power to charge the target electric vehicle, the user only needs to separately take out the host in the electric vehicle charging control system, and separately charge the target electric vehicle by using the host in the electric vehicle charging control system. In addition, in the process, compared with the whole electric vehicle charging control system, the host has the advantages of light weight and small volume, so that the portability of the electric vehicle charging control system in the use process can be further improved; if a user needs a direct current charger with higher power to charge a target electric automobile, and the host in the electric automobile charging control system cannot meet the charging requirement of the target electric automobile, at the moment, the user can use the host and the slave in the electric automobile charging control system together to charge the target electric automobile, so that the electric automobile charging control system can be used more flexibly and more variously.
It can be seen that, in this embodiment, when charging the target electric vehicle, first, the host in the electric vehicle charging control system is used to detect the target charging power required by the target electric vehicle, and determine whether the target charging power of the target electric vehicle is greater than the maximum output power of the host; if the target charging power of the target electric automobile is larger than the maximum output power of the master machine, the master machine sends a control instruction to the slave machine which is added into the electric automobile charging control system in advance, so that the slave machine controls the target power output device which is added into the electric automobile charging control system in advance to output a target power difference value, and meanwhile, the master machine also outputs the maximum output power of the master machine to the target electric automobile, so that the master machine and the slave machine can charge the target electric automobile together, and the target electric automobile can reach the target charging power. Obviously, compared with the prior art, in the embodiment, even when the charging power required by the target electric vehicle is greater than the maximum output power of the host, the electric vehicle charging control system can charge the target electric vehicle, so that the user experience of the user in the process of using the electric vehicle charging control system can be significantly improved.
Based on the foregoing embodiments, this embodiment further describes and optimizes the technical solution, specifically, in step S12: after the process of determining whether the target charging power is greater than the maximum output power of the host, the method further includes:
and if not, outputting the target charging power to the target electric automobile.
In practical applications, the host of the electric vehicle may also be used to charge the target electric vehicle alone, that is, if the target charging power of the target electric vehicle is smaller than the maximum output power of the host, the host may be directly used to charge the target electric vehicle, that is, the host is used to output the target charging power to the target electric vehicle.
Specifically, when the target charging power of the target electric vehicle is smaller than the maximum output power of the host, the host converts the alternating current input into the electric vehicle charging control system into direct current, and then inputs the direct current into the target electric vehicle, so that the charging power of the target electric vehicle can reach the target charging power.
Therefore, through the technical scheme provided by the embodiment, the working mode of the electric automobile charging control system can be more various and flexible.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, specifically, the steps are as follows: the process of sending a control command to a slave which is added to an electric vehicle charging control system in advance comprises the following steps:
and sending a control command to a slave machine which is added to the electric automobile charging control system in advance by using an RS485 bus.
Specifically, in this embodiment, the master may send the control command to the slave that is added to the electric vehicle charging control system in advance through the RS485 bus, because the RS485 bus has not only stable data transmission performance, but also good anti-noise interference performance, so when the master sends the control command to the slave through the RS485 bus, the influence of other interference signals on the transmission process of the control command may be avoided, and thus the control command may be sent to the slave more stably and reliably.
Obviously, the technical scheme provided by the embodiment can further increase the overall stability and reliability of the control command in the transmission process.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, specifically, the steps are as follows: the process of sending a control command to a slave which is added to an electric vehicle charging control system in advance comprises the following steps:
and sending a control command to a slave machine which is added to the electric automobile charging control system in advance by using the CAN bus.
In practical application, the master CAN send the control command to the slave through a CAN bus (Controller Area Network) in addition to the RS485 bus, and the master CAN send the control command to the slave through the CAN bus, because the CAN bus has the characteristic of high transmission speed, and the CAN bus has outstanding reliability and real-time performance compared with other communication buses, when the master sends the control command to the slave through the CAN bus, the master CAN send the control command to the slave more accurately and timely.
Of course, in practical applications, the control command may be transmitted by using a field bus, a wireless hart (high way Addressable Remote transmitter), in addition to the RS485 bus and the CAN bus, and the control command is not limited in this respect.
Obviously, by the technical scheme provided by the embodiment, the transmission efficiency of the control instruction in the transmission process can be improved, and the transmission mode of the control instruction can be more flexible and diversified.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the target power output device is specifically an AC/DC power conversion unit.
Specifically, in this embodiment, the target power output device is set as an AC/DC (alternating Current/Direct Current) power conversion unit, because the AC/DC power conversion unit is a relatively common AC to DC device, not only can the universality of the method provided by the present application in practical applications be relatively improved, but also the AC/DC power conversion unit can be used to connect the electric vehicle charging control system with a common household AC power supply, and the common household AC power supply is used as an emergency charging device or a backup charging device, so that even in a place where a user is out without a charging pile, the user can also use the electric vehicle charging control system provided by the present application to charge the target electric vehicle. Obviously, through such a setting mode, convenience of a user in the process of using the electric vehicle charging control system can be further improved, and manufacturing cost of the user in the process of using the electric vehicle charging control system can be relatively reduced.
Therefore, by the technical scheme provided by the embodiment, the user experience of the user in the process of using the electric automobile charging control system can be further improved.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the target power output device has a maximum output current value and a maximum output voltage value.
In this embodiment, a maximum output current value and a maximum output voltage value are also set for the target power output device, that is, when the current or voltage output by the target power output device exceeds the maximum output current value and the maximum output voltage value set for the target power output device in advance, the target power output device stops charging the target electric vehicle, so that an overcurrent phenomenon or an overvoltage phenomenon occurring during the charging process of the target electric vehicle by the target power output device can be avoided, and the safety of the target power output device in the use process can be further improved.
Therefore, the technical scheme provided by the embodiment can relatively improve the safety and reliability of the user in the process of using the electric vehicle charging control system.
