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

[0032] In the related art, when an electric vehicle is fast charged through a charging pile, the electric vehicle needs to monitor the status of the charging pile in real time. At present, domestic electric vehicles and charging piles use the Controller Area Network (CAN) communication protocol to exchange charging data with each other, while regions such as Europe use the Power Line Communications (PLC) communication protocol. In order to adapt the data communication protocol between the vehicle and the charging pile, the electric vehicle needs to be configured with a protocol conversion chip in the charging control system. However, the current setting method of the protocol conversion chip requires reserving the setting space of the chip and the setting space of the corresponding connecting harness, which makes the space utilization rate of the car low, and then leads to an increase in the design and production cost of the car. Therefore, how to improve the space utilization rate of the car has become a technical problem that needs to be solved urgently.

[0033] Based on this, an embodiment of the present utility model provides an electric vehicle area control system and an electric vehicle, which can exchange charging data with charging piles of different data communication forms.

[0034] like Figure 1 As shown, an embodiment of the present invention provides an electric vehicle regional control system, wherein the regional control system includes a plurality of sub-regional control systems, and any of the sub-regional control systems includes: a protocol conversion module 100 and a regional main control module 400 .

[0035] Reference Figure 1 The electric vehicle area control system is applied to electric vehicles. The electric vehicle 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, and the external charging device is used to provide initial charging communication data and charging information.

[0036] 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 operations according to the charging control signal to control the charging status of the energy storage battery 500 by the external charging device.

[0037] 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 target charging communication data. The first communication protocol is a communication protocol for external charging equipment to transmit initial charging communication data, such as the power line carrier (Party Line Communications, PLC) communication protocol used by European charging piles or the controller area network (Controller Area Network, CAN) communication protocol used by domestic charging piles; the charging signal input port of the regional master control module 400 is connected to the charging signal output port of the protocol conversion module 100. The regional master control module 400 is used to process the target charging communication data to obtain a charging control signal. The processing method of the target charging communication data can be selected according to actual conditions. For example, when the target charging communication data has secondary encoding, the target charging communication data is secondary decoded.

[0038] Specifically, an external charging device, such as an electric vehicle charging station, is 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 is connected to the charging interface 300 via a device such as a charging gun. The charging interface 300 includes a data communication sub-interface for exchanging charging data and a charging sub-interface for charging the energy storage battery 500.

[0039] The following embodiments illustrate an example in which an external charging device transmits initial charging communication data using the European standard PLC communication protocol. 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 subport 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 regional master 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 from the initial charging communication data. After obtaining the charging parameters, the protocol conversion module 100 determines whether to perform secondary compilation based on actual needs. If secondary compilation is required, the communication protocol is selected to compile the charging parameters to obtain target charging communication data. If secondary compilation is not required, the charging parameters are directly used as the target charging communication data. Preferably, the protocol conversion module 100 compiles the obtained charging parameters into target charging communication data that conforms to the Serial Peripheral Interface (SPI) communication protocol and transmits the target charging communication data to the regional master control module 400 via the SPI bus.

[0040] In some specific embodiments of the present invention, the protocol conversion module 100 is an Electric Vehicle Communication Controller (EVCC), and the protocol conversion module 100 includes a modem chip, and the model of the modem chip is QCA7005-AL33.

[0041] The charging signal output port of the regional master 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 master control module 400 performs protocol parsing on the target charging communication data if the target charging communication data has been re-interpreted, obtaining charging parameters such as charging capacity and charging rate. If the target charging communication data has not been re-interpreted, the regional master control module 400 directly obtains charging parameters such as charging capacity and charging rate and configures corresponding charging control signals based on the charging parameters. The charging control signals generated by the regional master control module 400 can be CAN communication signals, which the regional master control module 400 transmits to the battery management module 200 via the CAN bus. The regional master 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 signals, the battery management module 200 controls the high-voltage relay between the charging interface 300 and the energy storage battery 500 to control the charging status of the energy storage battery 500 by the external charging device.

[0042] According to the electric vehicle regional control system of the present embodiment, the protocol conversion module 100 converts initial charging communication data transmitted using different data communication protocols into communication data that can be parsed by the regional master control module 400, enabling the electric vehicle to exchange charging data with charging stations using different data communication protocols. The electric vehicle regional control system of this embodiment integrates the protocol conversion module 100 into the electric vehicle's regional control system. Because the regional control system already has sufficient space for the protocol conversion module, there is no need to reserve space elsewhere in the vehicle for the protocol conversion module or the corresponding wiring harness. This improves vehicle space utilization and reduces vehicle design and production costs.

[0043] like Figure 1 As shown, in some specific embodiments of the present invention, 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 master 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 configured to control data transmission between the regional master 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 and is typically the charging protocol used in the main production or sales location 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 charging in the main production or sales location, since the regional charging protocol is the same as the second charging protocol, no protocol conversion is required by the protocol conversion module 100 during charging.

[0044] Connect as Figure 1As shown, in some specific embodiments of the present invention, 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 transceiver is connected to the charging signal output port of the regional master control module 400, and the charging signal input port of the controller area network transceiver is connected to the battery management module 200 of the electric vehicle. The controller area network transceiver is used to control data transmission between the regional master control module 400 and the battery management module 200 according to the controller area network protocol; the charging signal input port of the Ethernet transceiver is connected to the charging signal output port of the regional master control module 400, and the charging signal input port of the Ethernet transceiver is connected to the battery management module 200 of the electric vehicle. The Ethernet transceiver is used to control data transmission between the regional master control module 400 and the battery management module 200 according to the Ethernet protocol; the charging signal input port of the serial communication network transceiver is connected to the charging signal output port of the regional master control module 400, and the charging signal input port of the serial communication network transceiver is connected to the battery management module 200 of the electric vehicle. The serial communication network transceiver is used to control data transmission between the regional master control module 400 and the battery management module 200 according to the serial communication network protocol.

[0045] Specifically, the controller area network transceiver implements data exchange between the regional master control module 400 and the battery management module 200 via the Controller Area Network (CAN) protocol and the CAN bus. The Ethernet transceiver implements data exchange between the regional master control module 400 and the battery management module 200 via the Ethernet protocol and the serial communication network transceiver implements data exchange between the regional master control module 400 and the battery management module 200 via the serial communication network and the serial communication network protocol. The regional master control module 400 can select any communication method to exchange data with the battery management module 200. It is understood that the controller area network transceiver, Ethernet transceiver, and serial communication network transceiver can also be connected to other control modules in the electric vehicle to enable data exchange between the regional master control module 400 and other control modules in the electric vehicle.
