The invention discloses a power battery pack device, a heating control system and an electric automobile, the power battery pack device comprises a first power battery pack, a first switch module and a first energy storage module which are connected in sequence, and a second power battery pack, a second switch module and a second energy storage module which are connected in sequence, and the first energy storage module is further connected with the second energy storage module; the anode of the first power battery pack is also connected with the anode of the second power battery pack, or the cathode of the first power battery pack is also connected with the cathode of the second power battery pack. A loop is formed among a first power battery pack, a first switch module, a first energy storage module, a second energy storage module, a second switch module and a second power battery pack, high-frequency pulse current can be formed in the loop through alternate charging and discharging between the two power battery packs, and then the high-frequency pulse current is used for heating the power battery packs. According to the design, an additional heating device is not needed, the cost is saved, and the design complexity is reduced.
