After the battery pack is charged and discharged in winter, the temperature in the battery pack and the temperature in the battery bin need to be maintained, meanwhile, a worker rest room and a customer tea rest room need to be heated, and the heat recovery air conditioning system of the power station starts a fourth working mode.
When the battery pack is charged and discharged in winter, the battery pack needs to be refrigerated, and if the number of the battery packs charged and discharged simultaneously is small, the battery bin, the worker rest room and the customer tea rest room need to be heated. The battery replacement station heat recovery air conditioning system starts a fifth working mode, recovers heat emitted during charging and discharging of the battery pack and is used for heating the battery bin, the worker rest room and the customer tea rest room.
