The invention relates to the technical field of vehicles, in particular to a vehicle cold start method and device, the method is applied to a vehicle with a battery system, the battery system comprises a temperature sensor, a battery management module and N battery modules, and the N battery modules are sequentially connected into a ring. Detecting whether the temperature in the battery system is lower than a preset value or not through a temperature sensor, wherein the preset value is a temperature value at which the vehicle cannot be started; if yes, the battery management module controls the N battery modules to discharge to the adjacent battery modules in sequence, so that each battery module in the N battery modules is heated, cold start of the vehicle is achieved, then the vehicle can be quickly started, and the efficiency of starting the vehicle under the severe environment condition is improved.

    本发明涉及车辆技术领域,尤其涉及一种车辆冷启动的方法及装置,该方法应用于具有电池系统的车辆中,电池系统包括温度传感器、电池管理模块以及N个电池模块,其中,N个电池模块顺次连接成环,该方法包括:在车辆启动时,通过温度传感器检测电池系统中的温度是否低于预设值,该预设值为车辆无法启动的温度值;若是,通过电池管理模块控制N个电池模块依次向相邻的电池模块放电,以使N个电池模块中每个电池模块升温,实现车辆的冷启动,进而能够快速启动车辆,提高了在环境恶劣的条件下启动车辆的效率。
