The invention relates to a heating system for an easily-detachable power battery of a hybrid electric vehicle. The system is used for controlling the temperature of the power battery of the vehicle by using a vehicle body energy emission system and providing a proper temperature for normal work of the battery so as to improve the working efficiency of the power battery and prolong the service life of the power battery. The invention further discloses a heating method of the easily-detachable hybrid electric vehicle power battery. The control logic of the heating method comprises the steps that the working state of the vehicle is judged, and if the working state is a pure engine working state, heating control is conducted in an engine heating mode; if so, whether an engine is started for heating or not is judged according to the battery temperature; and if the working state is the hybrid power working state, heating is carried out according to a hybrid power working heating mode. According to the scheme, the problems that an existing battery heating mode is single, complex working conditions cannot be met, the cost of the whole vehicle is increased, the limited space of the whole vehicle is occupied, the weight and energy consumption of the whole vehicle are increased, and the battery and a heat preservation box are difficult to disassemble for repairing, replacing, cleaning and maintaining are solved.

    本发明涉及一种易拆卸的混合动力汽车动力电池的加热系统,该系统运用车身排放能量系统,对汽车动力电池的温度进行控制,电池正常工作提供适宜温度,以提升动力电池的工作效率和使用寿命。本发明还公开了一种易拆卸的混合动力汽车动力电池的加热方法,其控制逻辑为:判断汽车的工作状态,若为纯发动机工作状态则通过发动机加热模式进行加热控制;若为纯电动工作状态则通过电池温度判断是否启动发动机进行加热;若为混合动力工作状态则按混合动力工作加热模式进行加热。本方案解决了现有电池加热方式单一、不能满足复杂工况、增加整车成本、占用整车有限的空间、增加整车重量及能耗以及不易拆卸进行如修理及更换、清洁、保养电池及保温箱的问题。
