The invention provides a power battery charging device, a vehicle, a charging method, equipment and a program product, the device comprises a heating assembly, a power battery, a vehicle-mounted processor and a switch module, and the heating assembly comprises a first driving motor, a second driving motor and a PTC heater; if the battery temperature is not greater than the preset temperature threshold and the residual electric quantity is not less than the preset electric quantity threshold, controlling the switch module to be switched off, and controlling the heating assembly to enter a first heating mode to heat the power battery; the first heating mode comprises a pulse self-heating mode and at least one heating mode of a locked-rotor heating mode corresponding to the second driving motor and a PTC heating mode corresponding to the PTC heater, and when the battery temperature reaches a preset temperature threshold value, the first driving motor is controlled to stop working and the switch module is controlled to be closed. Therefore, the external power supply charges the power battery. According to the embodiment of the invention, the problem of overtime exit of the external power supply in the pulse self-heating mode can be avoided.

    本公开提供了一种动力电池的充电装置、车辆、充电方法、设备及程序产品,该装置包括加热组件、动力电池、车载处理器及开关模块,加热组件包括第一驱动电机、第二驱动电机及PTC加热器,若电池温度不大于预设温度阈值且剩余电量不小于预设电量阈值,控制开关模块断开,并控制加热组件进入第一加热模式为动力电池加热;第一加热模式包括脉冲自加热模式,以及第二驱动电机对应的堵转加热模式和PTC加热器对应的PTC加热模式中的至少之一的加热模式,在电池温度达到预设温度阈值时,控制第一驱动电机停止工作及开关模块闭合,以使外部电源为动力电池充电。本公开实施例,可以避免脉冲自加热模式下的外部电源的超时退出的问题。
