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.

    一种动力电池组装置、加热控制系统及电动汽车,动力电池组装置包括依次连接的第一动力电池组、第一开关模组和第一储能模组、以及依次连接的第二动力电池组、第二开关模组和第二储能模组,第一储能模组还和第二储能模组相连,第一动力电池组的阳极还和第二动力电池组的阳极相连,或第一动力电池组的阴极还和第二动力电池组的阴极相连。通过在第一动力电池组、第一开关模组、第一储能模组、第二储能模组、第二开关模组和第二动力电池组之间构成回路,能通过两个动力电池组之间的交替充放电在该回路中形成高频脉冲电流,进而利用该高频脉冲电流加热动力电池组,该设计无需额外设置加热装置,有助于节省成本,降低设计的复杂性。
