Cooling liquid supplementing method and device, vehicle and storage medium

The invention provides a cooling liquid supplementing method and device, a vehicle and a storage medium. The method comprises the steps that the state between a battery pack loop and a warm air loop of the vehicle is judged; when it is determined that the battery pack loop and the warm air loop are in the separated state, whether the battery pack loop needs to be supplemented with cooling liquid or not is judged; and under the condition that it is determined that the battery pack loop needs to be supplemented with the cooling liquid, the battery pack loop and the warm air loop are controlled to be communicated, so that the cooling liquid of the battery pack loop is supplemented. According to the method, when it is determined that the battery pack loop needs to be supplemented with the cooling liquid, the battery pack loop and the warm air loop are controlled to be communicated, water in the warm air loop serves as the cooling liquid to supplement the cooling liquid in the battery pack loop, the cooling liquid
