The invention discloses a charging and heating system for a power battery, the whole system is composed of a commercial power grid interface, the power battery, a controller, a DC-DC rectifier module, an engine and a generator, and relays are arranged among the above modules to control on-off. When the system is started, the controller can automatically determine whether to heat or charge the power battery by detecting the temperature, the voltage and the safety condition of the power battery. According to the system, heating and charging are combined, the size of the system is greatly reduced, the energy loss caused by battery heating is reduced by adopting a battery self-heating mode, and the heating efficiency and speed are improved.

    本发明公开一种用于动力电池的充电和加热系统,整个系统由市电电网接口、动力电池、控制器、DC‑DC整流模块、发动机和发电机组成,上述各模块的连接之间均设置有继电器来控制通断,在系统启动时控制器可通过检测动力电池的温度、电压和安全状况来自行决定是否为动力电池加热或充电。本发明系统将加热与充电相结合,极大的减小了系统的体积,并采用电池自加热方式来降低电池加热所造成的能量损耗,提高了加热效率和速度。
