The invention provides a power battery PACK. The power battery PACK comprises a box body; at least one battery module; a BMS control panel; a DCDC module; wherein the battery module is mounted and fixed on the box body; wherein the BMS control panel is in communication connection with the battery module and the DCDC module; the BMS control panel is used for controlling the battery module to operate and discharging to an external system through the DCDC module; and the DCDC module further comprises a DCDC switch key used for driving or stopping the DCDC module to work. According to the invention, the battery PACK with the DCDC module is adopted, so that the internal work of the battery module can be effectively controlled; invalid discharge of the battery module can be avoided; the overallutilization rate of electric energy is increased; heat conduction silica gel is arranged between battery cells in the battery module and between the battery module and the inner wall of the box body respectively; and current can be effectively isolated while heat dissipation is conducted.
本发明提供一种动力电池PACK,所述电池PACK包括:箱体;至少一个电池模组;BMS控制板;DCDC模块;其中所述电池模组安装固定于所述箱体,所述BMS控制板通讯连接所述电池模组和DCDC模块,所述BMS控制板用于控制所述电池模组运行,通过所述DCDC模块向外部系统放电,所述DCDC模块还包括DCDC开关键,用于驱动或停止所述DCDC模块工作;本发明采用具有DCDC模块的电池PACK可有效地控制电池模组内部的工作,可避免电池模组自身的无效放电,提高电能整体利用率,并且电池模组内部电芯之间以及电池模组和箱体内壁之间分别设有导热硅胶,在散热的同时可有效地隔绝电流。
