The invention relates to the technical field of new energy vehicles, in particular to a battery pack with replaceable battery cells. The battery pack with replaceable battery cells comprises a batterycell module and a battery pack shell, the battery cell module comprises a plurality of battery cells, an electric appliance connecting box and a battery management system area, and a high-voltage connecting position and a low-voltage connecting position of the battery cells are arranged at the bottom of the battery pack by adopting a quick-plug high-voltage connecting mode; and the lower part ofthe battery pack shell is of a detachable structure. According to the CTP battery pack with the replaceable battery cells, when the battery cells in the CTP battery pack go wrong, the positions of thefaulty battery cells can be determined through a BMS, the positions of the battery cell modules needing to be replaced are determined, the battery cell modules are replaced, the operation process that the battery pack is detached from a vehicle can be omitted, detaching and installing can be completed on a vehicle body, and the efficiency is higher.

    本发明涉及新能源汽车技术领域,更具体的说,涉及一种可更换电芯的电池包。本发明提出的可更换电芯的电池包,包括电芯模块和电池包壳体:所述电芯模块,包括多个电芯、电器连接盒和电池管理系统区域分割组成,采用快插高压连接方式将电芯的高压连接位置和低压连接位置设置在电池包底部;所述电池包壳体,下部为可拆卸结构。本发明提出的一种可更换电芯的CTP电池包,当CTP电池包中电芯出现问题时,可以通过BMS确认问题电芯位置,确定需要更换的电芯模块的位置,进行电芯模块的更换操作,能够免去电池包从车上拆卸下来的操作流程,在车身即可完成拆卸和安装,效率更高。
