The color electronic screen 1031 is connected to the module controller 102.

[0042] Embodiment 3 of the battery status display structure of the utility model electric vehicle

[0043] The battery status display structure of the electric vehicle of the utility model is further as follows: Figure 1 As shown, the vehicle control unit 200 includes a domain controller 21 connected to the signal transceiver 101 , the domain controller 21 is connected to an intelligent control system 22 , and the intelligent control system 22 is connected to a management system 23 .

[0044] Further, such as Figure 1 As shown, the domain controller 21 includes a key detection module 211, which is connected to the signal transceiver 101 and the intelligent control system 22. The key detection module 211 is used to detect whether there is a vehicle key of the electric vehicle within a preset range; if the key detection module 211 detects the vehicle key, the domain controller 21 is triggered to send battery and other related information to the signal transceiver 101 and refresh the display of the corresponding information. If the vehicle key is not detected, the domain controller 21 is triggered to stop sending information to the signal transceiver 101 after a preset time to achieve energy saving.

[0045] Further, such as Figure 1 As shown, the domain controller 21 also includes an early warning prompt module 212, which is connected to the intelligent control system 22 and the off-vehicle display unit 100. The early warning prompt module 212 performs an early warning prompt when it receives an early warning signal sent by the domain controller 21. The early warning signal is sent by the domain controller 21 when the battery of the electric vehicle has been discharged to a warning value. The early warning prompt module 212 sends an early warning signal when the battery power reaches the warning value, and prompts through the off-vehicle display unit 100 or other methods (such as sound, light).

[0046] Further, such as Figure 1As shown, the management system 23 includes a battery management system 231, which is connected to the intelligent control system 22 for obtaining relevant information of the battery.

[0047] Further, such as Figure 1 As shown, the management system 23 also includes a vehicle status management system 232, which is connected to the intelligent control system 22 and is used to obtain relevant information about the vehicle status.

[0048] When the electric vehicle is in a turned-off or dormant state, the vehicle control unit 200 and the vehicle exterior display unit 100 are both in a standby mode, and the domain controller 21 and the intelligent control system 22 of the vehicle control unit 200 continuously monitor the vehicle state and maintain communication with the management system 23;

[0049] When a user approaches the vehicle with the vehicle key of the electric vehicle, the key detection module 211 starts to work. The key detection module 211 detects whether there is a vehicle key within a preset range through a wireless signal. If the key detection module 211 detects the vehicle key, the domain controller 21 is triggered to start working. The domain controller 21 sends a request to the management system 23 through the intelligent control system 22 to obtain information such as the battery status and the vehicle status. The battery management system 231 and the vehicle status management system 232 in the management system 23 respectively provide relevant information about the battery status and the vehicle status to the intelligent control system 22. The acquired information is sent to the signal transceiver 101. After receiving the information, the signal transceiver 101 transmits it to the module controller 102. After the module controller 102 processes the information, it sends it to the display module 103. The display module 103 displays the information outside the vehicle body through the color electronic screen 1031 Battery status, vehicle status and other information. If the battery management system 231 detects that the battery power reaches the warning value, the intelligent control system 22 will trigger the warning prompt module 212. The warning prompt module 212 sends a warning signal to the external display unit 100. The display module 103 will perform a special display (such as flashing, changing color, etc.) to remind the user. The display module 103 will continuously update the displayed battery status and other information to ensure that the information obtained by the user is real-time. If the key detection module 211 does not detect the vehicle key within a period of time, the domain controller 21 will trigger to stop sending information to the signal transceiver 101 after a preset time to save energy. When the user leaves the vehicle and locks the door, the key detection module 211 will detect that the vehicle key has left the preset range, and the domain controller 21 will trigger the vehicle control unit 200 and the external display unit 100 to enter standby mode and wait for the next trigger.
