[0057] Specifically, if the external environment temperature is less than or equal to the environment temperature threshold and the battery temperature is less than or equal to the battery temperature threshold, it indicates that the external environment temperature is low and the battery temperature is also low at this time, the vehicle-mounted battery preheating time is long, the vehicle-mounted battery is in a low-efficiency output state, and the battery state information can be determined as low-performance state information. If the external environment temperature is greater than the environment temperature threshold, it indicates that the external environment temperature is high at this time, and if the battery temperature is low, the vehicle-mounted battery can be quickly heated by the external environment temperature, which can effectively avoid the vehicle-mounted battery in a low-efficiency output state.

[0074] Specifically, the whole vehicle control module 1 can be used to supply power to the heating module 3 when the solar power is greater than or equal to the first preset power supply power, which means that the solar power can meet the power supply demand of the heating module 3, and at this time, the heating module 3 can be preferentially powered to reduce the energy consumption of the vehicle; if the solar power is less than the preset power supply power, it means that the solar power cannot meet the power supply demand of the heating module 3, and at this time, the power supply module 5 can be controlled to supply power to the heating module 3.
