Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] In related technologies, when electric vehicles (EVs) are fast-charging via charging stations, the EVs need to monitor the status of the charging stations in real time. Currently, domestic EVs and charging stations use the Controller Area Network (CAN) communication protocol for mutual charging data exchange, while regions like Europe use the Power Line Communications (PLC) protocol. To achieve compatibility of data communication protocols between the vehicle and the charging station, EVs need to configure a protocol conversion chip in their charging control system. However, the current method of configuring the protocol conversion chip requires reserving space for the chip and corresponding wiring harnesses, resulting in low space utilization in the vehicle and increased design and production costs. Therefore, improving the space utilization of vehicles has become an urgent technical problem to be solved.

[0035] Based on this, embodiments of this application provide an electric vehicle area control system and an electric vehicle, which can interact with charging piles of different data communication forms to exchange charging data.

[0036] As shown in Figure 1, this application embodiment provides an electric vehicle area control system, which includes multiple sub-area control systems. Any one of the sub-area control systems includes a protocol conversion module 100 and an area main control module 400.

[0037] Referring to Figure 1, the electric vehicle area control system is applied to an electric vehicle, which includes a battery management module 200, a charging interface 300, and an energy storage battery 500. The charging interface 300 is connected to an external charging device, which provides initial charging communication data and charging signals.

[0038] The battery management module 200 is connected to the regional main control module 400, the charging interface 300 and the energy storage battery 500 respectively. The battery management module 200 is used to perform relay switching operation according to the charging control signal to control the charging status of the external charging device to the energy storage battery 500.

[0039] The charging signal input port of the protocol conversion module 100 is connected to the charging interface 300 of the electric vehicle. The protocol conversion module 100 decodes the received initial charging communication data according to the first communication protocol to obtain the target charging communication data. The first communication protocol is the communication protocol for external charging equipment to transmit initial charging communication data, such as the power line carrier (PLC) communication protocol used in European charging piles or the controller area network (CAN) communication protocol used in domestic charging piles. The charging signal input port of the area master control module 400 is connected to the charging signal output port of the protocol conversion module 100. The area master control module 400 is used to process the target charging communication data to obtain the charging control signal. The processing method of the target charging communication data can be selected according to the actual situation. For example, if the target charging communication data has secondary encoding, the target charging communication data is decoded twice.

[0040] Specifically, external charging devices, such as electric vehicle charging piles, are used to charge the energy storage battery 500. When charging the electric vehicle, the external charging device provides initial charging communication data, which includes charging parameters such as charging capacity and charging rate. The external charging device connects to the charging interface 300 via a device such as a charging gun. The charging interface 300 includes a data communication sub-interface for charging data exchange and a charging sub-interface for charging the energy storage battery 500.

[0041] The following embodiments illustrate the use of an external charging device employing the European standard PLC communication protocol to transmit initial charging communication data as an example. Specifically, the initial charging communication data is sent to the charging interface 300 in the form of a power line carrier signal. The data communication sub-port of the charging interface 300 is connected to the charging signal input port of the protocol conversion module 100, and the charging signal output port of the protocol conversion module 100 is connected to the charging signal input port of the area control module 400. The protocol conversion module 100 receives the initial charging communication data and decodes it according to the PLC communication protocol to obtain charging parameters such as charging capacity and charging rate. After obtaining the charging parameters, it determines whether secondary compilation is required based on actual needs. If secondary compilation is required, the communication protocol is selected to compile the charging parameters to obtain the target charging communication data; if secondary compilation is not required, the charging parameters are directly used as the target charging communication data. Optionally, the protocol conversion module 100 compiles the obtained charging parameters into target charging communication data conforming to the Serial Peripheral Interface (SPI) communication protocol and sends the target charging communication data to the area control module 400 via the SPI bus.

[0042] In some specific embodiments of this application, the protocol conversion module 100 is an Electric Vehicle Communication Controller (EVCC), and the protocol conversion module 100 includes a modem chip, the model of which is QCA7005-AL33.

[0043] The charging signal output port of the regional main control module 400 is connected to the charging signal receiving port of the battery management module 200. After receiving the target charging communication data, the regional main control module 400 performs protocol parsing on the target charging communication data if it has been recompiled, obtaining charging parameters such as charging capacity and charging rate. If the target charging communication data has not been recompiled, it directly obtains charging parameters such as charging capacity and charging rate, and configures the corresponding charging control signal according to the charging parameters. The charging control signal generated by the regional main control module 400 can be a CAN communication signal, which is sent to the battery management module 200 via the CAN bus. The regional main control module 400, charging interface 300, and energy storage battery 500 are all connected to the battery management module 200. After receiving the charging control signal, the battery management module 200 controls the switching of the high-voltage relay between the charging interface 300 and the energy storage battery 500, thereby controlling the charging status of the energy storage battery 500 by the external charging device.

[0044] According to the electric vehicle area control system of this application embodiment, the protocol conversion module 100 converts initial charging communication data transmitted using different data communication protocols into communication data that the area main control module 400 can parse, enabling the electric vehicle to interact with charging piles using different data communication protocols. In this embodiment, the electric vehicle area control system integrates the protocol conversion module 100 into the electric vehicle area control system itself. Since the area control system already has sufficient space to configure the protocol conversion module, there is no need to reserve space for configuring the protocol conversion module and corresponding connection harnesses in other locations on the electric vehicle, thus improving the space utilization of the vehicle and reducing the design and production costs.

[0045] As shown in Figure 1, in some specific embodiments of this application, the electric vehicle regional control system further includes a communication module 600. The charging signal input interface of the communication module 600 is connected to the charging signal output port of the regional main control module 400, and the charging signal output port of the communication module 600 is connected to the battery management module 200 of the electric vehicle. The communication module 600 is used to control the data transmission between the regional main control module 400 and the battery management module 200 according to a second communication protocol. The second communication protocol is different from the first communication protocol. The second communication protocol is typically the charging protocol used in the main production or sales area of ​​the electric vehicle. For example, the second communication protocol for state-owned electric vehicles is set to the CAN communication protocol, while the second communication protocol for electric vehicles sold in Europe is set to the PLC communication protocol. When the electric vehicle is charged in the main production or sales area, since the regional charging protocol is the same as the second charging protocol, protocol conversion is not required through the protocol conversion module 100 during charging.

[0046] As shown in Figure 1, in some specific embodiments of this application, the second communication protocol includes a controller area network protocol, an Ethernet protocol, or a serial communication network protocol, and the communication module 600 includes: a controller area network transceiver, an Ethernet transceiver, and a serial communication network transceiver. The charging signal input port of the Controller Area Network (CLAN) transceiver is connected to the charging signal output port of the area master control module 400, and also to the battery management module 200 of the electric vehicle. The CLAN transceiver is used to control data transmission between the area master control module 400 and the battery management module 200 according to the CLAN protocol. Similarly, the charging signal input port of the Ethernet transceiver is connected to the charging signal output port of the area master control module 400, and also to the battery management module 200 of the electric vehicle. The Ethernet transceiver is used to control data transmission between the area master control module 400 and the battery management module 200 according to the Ethernet protocol. Finally, the charging signal input port of the serial communication network transceiver is connected to the charging signal output port of the area master control module 400, and also to the battery management module 200 of the electric vehicle. The serial communication network transceiver is used to control data transmission between the area master control module 400 and the battery management module 200 according to the serial communication network protocol.

[0047] Specifically, the Controller Area Network (CAN) transceiver uses the CAN protocol and a CAN bus to facilitate data exchange between the regional control module 400 and the battery management module 200. The Ethernet transceiver uses the Ethernet protocol and an Ethernet network to facilitate data exchange between the regional control module 400 and the battery management module 200. The Serial Communication Network (LIN) transceiver uses the Serial Communication Network (LIN) protocol and a serial communication network to facilitate data exchange between the regional control module 400 and the battery management module 200. The regional control module 400 can choose any of these communication methods to interact with the battery management module 200. It is understood that the CAN transceiver, Ethernet transceiver, and LIN transceiver can also connect to other control modules in the electric vehicle to enable data exchange between the regional control module 400 and other control modules in the electric vehicle.

The front right area main control module is communicatively connected to the rear area main control module and the front left area main control module, respectively. The rear area main control module, the front right area main control module, and the front left area main control module communicate with each other in pairs.

[0052] Specifically, referring to Figure 2, the electric vehicle can be equipped with three Zone Control Units (ZCUs): the front right zone control system ZCUFR, the front left zone control system ZCUFL, and the rear zone control system ZCUR.

The ZCUFR connects to the front right body load of the electric vehicle via this module, enabling body control of the front right body load. Similarly, the front left zone control system (ZCUFL) also includes a front left body control module. The ZCUFL connects to the front left body load of the electric vehicle via this module, enabling body control of the front left body load. Finally, the rear zone control system (ZCUR) includes a rear body main control module. The ZCUR connects to the rear body load of the electric vehicle via this module, enabling body control of the rear body load.

[0054] Specifically, the aforementioned vehicle body control can include the control of seats, doors, rearview mirrors, headlights, keyless entry, intelligent power distribution, etc., in corresponding areas.
