The invention relates to the field of automobiles, in particular to a method and device for controlling battery swapping and charging of an electric vehicle. Including replacing the power battery, supplementing the power battery coolant; charging; draining the coolant after charging is completed, for backup. The invention can effectively prevent the power battery coolant from leaking during the process of replacing the power battery and before and after the replacement charging process of the electric vehicle, and avoid the overheating damage of the power battery caused by insufficient cooling liquid during the charging process of the power battery or the low charging efficiency of the power battery Thermal management issues to ensure the service life of the power battery and vehicle safety.
Description
Electric vehicle charging control method and device technical field The invention belongs to the technical field of electric vehicle batteries, and in particular relates to a control method for electric vehicle battery swapping and charging and device. Background technique [0002] With the development of electric vehicle technology, especially the improvement of the energy density and power of the power battery, the The cruising range has been improved, but there is still a need for quick replacement of power batteries in the market, especially for commercial vehicles. for electric One of the difficulties in replacing the power battery of a vehicle is to solve the problem that the power battery coolant does not leak during the replacement process (now the power battery The battery generally adopts active water-cooling cooling method); also for the power exchange station, it is necessary to solve the problem of power battery replacement process. No coolant leaks. F...
