[0040] The working conditions are shown in the following table:

[0041]

[0042]

[0043] The main working principle and operation logic are as follows: Figure 7 and Figure 8 As shown;

[0044] The priority order of each sensor command in the present invention is: the rain sensor takes precedence over the external temperature and takes precedence over the internal temperature. The central control system first determines whether it is raining in the external environment through the feedback of the external rain sensor signal:

[0045] 1. If it is judged to be raining, the left movable cover, the right movable cover, and the rear movable cover are closed through the transmission motor. The exhaust device is closed through the ventilation system. The internal ambient temperature is judged through the internal temperature sensor signal feedback. If the internal ambient temperature is greater than 45°C, the air conditioning system is controlled to cool; if the internal ambient temperature is less than 5°C, the air conditioning system is controlled to heat.

[0046] 2. If it is determined that it is not raining, the external temperature sensor signal feedback is further analyzed as follows:

[0047] 1) If the external ambient temperature is greater than 5°C and the internal ambient temperature is greater than 45°C, the left movable cover, right movable cover, and rear movable cover are opened by controlling the movable cover motor. The air conditioning system is controlled to cool, the exhaust device is opened through the ventilation system, and the energy storage system is controlled to operate at a reduced rating through the PCS power conversion system.

[0048] 2) If the external ambient temperature is greater than 5°C and the internal ambient temperature is greater than 25°C and less than 45°C, the left movable cover is opened by controlling the movable cover motor, the right movable cover is opened, and the exhaust device is opened through the ventilation system.

[0049] 3) If the external environment temperature is greater than 5°C and the internal environment temperature is greater than 5°C and less than 25°C, the left movable cover is opened and the right movable cover is opened by controlling the movable cover motor.

[0050] 4) If the external ambient temperature is greater than 5°C and the internal ambient temperature is less than 5°C, the left movable cover, the right movable cover, and the rear movable cover are opened by controlling the movable cover motor to control the air conditioning system to heat.

[0051] 5) If the external ambient temperature is less than 5°C and the internal ambient temperature is greater than 45°C, the left movable cover, the right movable cover, and the rear movable cover are opened by controlling the movable cover motor. The air conditioning system is controlled to cool and the exhaust device is opened through the ventilation system.

[0052] 6) If the external ambient temperature is less than 5°C and the internal ambient temperature is greater than 25°C and less than 45°C, the left movable cover is opened and the right movable cover is opened by controlling the movable cover motor.

[0053] 7) If the external ambient temperature is less than 5°C and the internal ambient temperature is greater than 5°C and less than 25°C, none of the actuators will operate.

[0054] 8) If the external ambient temperature is less than 5°C and the internal ambient temperature is less than 5°C, control the air conditioning system to heat.
