When the battery module is in a low-temperature environment, the low-temperature main heating module, the low-temperature auxiliary heating module, the spraying module and the main circuit circulating module can be selected according to needs, and all the modules are matched for use. The battery module is preheated by the low-temperature main heating module, and at the moment, if the preheating of the battery module needs to be accelerated, the mode that the low-temperature auxiliary heating module, the main circuit circulating module and the spraying module are combined can be started to further heat the battery module.
The low-temperature main heating module comprises a box body 7, a battery module 8 consisting of a plurality of battery monomers, cooling liquid 10, a heater 33, a solid-state relay 34, a temperature sensor 35 and a liquid level sensor 36.
