The invention relates to a battery heating device and a vehicle, and the device comprises a power battery which comprises a first battery cell group and a second battery cell group; the first heating module is connected with the first battery cell group; the second heating module is connected with the second battery cell group; in a first state, the first heating module releases the stored electric energy to the first battery cell group, and the second heating module stores the electric energy released by the second battery cell group; and in the second state, the second heating module releases the stored electric energy to the second battery cell group, the first heating module stores the electric energy released by the first battery cell group, and the first state and the second state are executed alternately. By using the battery heating device provided by the invention, the power battery can be heated, so that the problem of low charging and discharging performance of the power battery in a low-temperature environment is avoided.

    本公开涉及一种电池加热装置与车辆,该装置包括:动力电池,该动力电池包括第一电芯组与第二电芯组;第一加热模块,该第一加热模块与该第一电芯组连接;第二加热模块,该第二加热模块与该第二电芯组连接;在第一状态下,该第一加热模块将存储的电能释放至该第一电芯组,该第二加热模块存储该第二电芯组释放的电能;在第二状态下,该第二加热模块将存储的电能释放至该第二电芯组,该第一加热模块存储该第一电芯组释放的电能,该第一状态和该第二状态交替执行。使用本公开提出的电池加热装置,可以对动力电池进行加热,以避免动力电池在低温环境下所产生的充放电性能低的问题。
