The invention belongs to the technical field of vehicle power battery temperature management, and particularly relates to a vehicle and a power battery temperature management method and system thereof. Controlling an electric drive heat dissipation module of a cooling device in the electric drive system to cool a cooling liquid in a cooling pipeline of the power battery; and when the temperature rising condition in the vehicle running process is met and the battery temperature is within the first set temperature range, cooling liquid in a cooling pipeline of a cooling device in the electric drive system is controlled to rise the temperature of cooling liquid in a cooling pipeline of the power battery. According to the environment temperature, the power battery is cooled by the electrically-driven cooling module, so that the cooling energy consumption of the power battery in the low-temperature environment is reduced; according to the vehicle state, the electric driving system is used for heating the power battery, so that the heating energy consumption of the power battery is reduced.

    本发明属于车辆动力电池温度管理技术领域,具体涉及一种车辆及其动力电池温度管理方法、系统,该方法在达到降温条件、环境温度不高于预设环境温度且电驱动系统中的冷却液温度不高于预设冷却液温度时,控制电驱动系统中冷却装置的电驱动散热模块对动力电池的冷却管路中的冷却液进行降温;在达到车辆行车过程中的升温条件且电池温度处于第一设定温度范围内,控制电驱动系统中冷却装置的冷却管路中的冷却液对动力电池的冷却管路中的冷却液进行升温。即根据环境温度,利用电驱动冷却模块对动力电池进行冷却,降低动力电池在低温环境下冷却能耗;根据车辆状态,利用电驱动系统对动力电池进行加热,来降低动力电池加热能耗。
