The invention discloses a power battery heating device and a heating method thereof. The power battery heating device is composed of a super capacitor, a heating control unit, a main control switch, apower battery, an external heating device, a battery thermal management system, an external heating control switch, a resistance-adjustable heating film and a temperature sensor. When the automobileis started in a low-temperature severe-cold environment, the heating control unit controls the super capacitor to be connected into the resistance-adjustable heating film and starts the external heating device according to a temperature signal of the temperature sensor, when the temperature reaches a preset threshold value, the heating control unit cuts off discharging of the super capacitor, andthe battery heat management system maintains the working temperature of the power battery. According to the invention, the power battery can be rapidly heated when being started in a low-temperature severe cold environment.

    本发明公开了一种动力电池加热装置及其加热方法,是由超级电容、加热控制单元、主控制开关、动力电池,外部加热装置,电池热管理系统,外部加热控制开关、电阻可调式加热膜以及温度传感器构成;汽车低温严寒环境启动时,加热控制单元根据温度传感器的温度信号控制超级电容接入电阻可调式加热膜以及启动外部加热装置,并在温度达到预设的阈值时,加热控制单元切断超级电容放电,由电池热管理系统维持动力电池的工作温度。本发明能使得动力电池在低温严寒环境下启动时候能实现快速加热。
