The battery module is arranged in a high-voltage battery pack at the bottom of the vehicle and is electrically connected to the regulating module.

[0021] The liquid cooling module is arranged on the outer surface of the high-voltage battery pack at the bottom of the vehicle and is electrically connected to the regulating module. The air cooling module is arranged on the outer surface of the high-voltage battery pack at the bottom of the vehicle and is electrically connected to the regulating module.

[0030] Working principle: After the user starts the vehicle with the key, the battery module starts to supply power. At the same time, the temperature monitoring module starts to monitor the temperature of the battery module in real time. The temperature monitoring module sends the real-time temperature data to the adjustment module. The adjustment module determines whether to start the liquid cooling module or the air cooling module for temperature adjustment based on the temperature data. If the temperature of the battery module exceeds the set range, the adjustment module will send instructions to the liquid cooling module or the air cooling module to work to maintain the battery module within a suitable operating temperature range. The battery health monitoring module continuously collects the operating data of the battery module, including voltage, current, temperature, etc. The collected operating data is processed by the data processor and the health status is evaluated by the health assessment software. The battery life prediction module predicts the battery life based on the health status evaluation results and the life prediction software. When the battery module power is lower than the set threshold, the adjustment module sends a charging instruction to the intelligent charging module. The intelligent charging module controls the charging interface through the charging controller to start charging. If the solar panel module installed on the top of the vehicle has enough energy, it will also provide power to the battery module for solar charging. The user terminal module displays information such as battery status, health assessment results, and predicted life to the user through the display screen.
