The invention belongs to the technical field of electric vehicles, and particularly relates to a novel PACK battery pack integrating a BMS and a bidirectional DCDC circuit for battery replacement. Thenovel PACK battery pack comprises an upper shell; a lower shell detachably and fixedly connected to the bottom of the upper shell; an integrated module arranged in a mounting cavity formed by combining the upper shell and the lower shell, wherein the integrated module is formed by integrating a BMS battery management module and a bidirectional DCDC module, and the bidirectional DCDC module is provided with an external interface; a control chip arranged in the mounting cavity and located on one side of the integrated module, wherein one end of the control chip is connected with the integratedmodule; and a battery cell arranged in the mounting cavity and positioned below the integrated module. According to the invention, the charging process can be completed only by the universal ACDC module instead of a DCDC module with a special model specification, so that the universality of the battery pack is improved.

    本发明属于电动车技术领域,具体涉及一种用于换电的集成BMS与双向DCDC电路的新型PACK电池包,包括:上壳体;下壳体,所述下壳体可拆地固定连接于所述上壳体底部;集成模块,所述集成模块设置于由所述上壳体和所述下壳体组合而成的安装腔内,所述集成模块是由BMS电池管理模块和双向DCDC模块集成而形成的,所述双向DCDC模块上具有对外接口;控制芯片,所述控制芯片设置于所述安装腔内且位于所述集成模块的一侧,所述控制芯片的一端与所述集成模块相连接;电池电芯,所述电池电芯设置于所述安装腔内且位于所述集成模块的下方。本发明无需专用型号规格的DCDC模块进行充电,只需要通用的ACDC模块即可完成充电过程,提高了电池包的通用性。
