By flexibly controlling the connection of the first cooling circuit or the connection of the second cooling circuit according to instructions, when the cockpit has a cooling demand (the control module receives the first instruction), the cockpit cooling module and the battery cooling module are controlled to be cooled separately, so that the cockpit cooling module and the battery cooling module are controlled to work simultaneously but do not affect each other, thereby avoiding the cooling interference problem caused by the cockpit and the battery module sharing the same cooling module; and when there is no cooling demand for the cockpit, the cockpit cooling module and the battery cooling module can be used to cool the battery module at the same time, so that the dual cooling modules can dissipate heat to the battery module at the same time, ensuring that the battery cooling meets the requirements and improving the cooling efficiency.

When the vehicle is driving and the cockpit needs to be cooled (the control module receives a first instruction), the first cooling circuit can be used to cool the air in the cockpit of the vehicle, and the battery cooling circuit can be used to cool the battery module, that is, the cockpit cooling module and the battery cooling module are controlled to be cooled separately, and the cockpit cooling module and the battery cooling module are controlled to work simultaneously but not affect each other, thereby avoiding the cooling interference problem caused by sharing a compressor and condenser.

[0055] In some embodiments, when there is no need to cool the cockpit, for example, when the vehicle is parked and charging, the second cooling circuit in the cockpit refrigeration module can be controlled to be connected, so that the cockpit refrigeration module and the battery cooling module can cool the battery module at the same time, realizing dual compressors and dual condensers to dissipate heat to the battery module at the same time, ensuring that the battery cooling meets the requirements and improving the cooling efficiency.
