The invention discloses a CTC power battery system, a battery pack and an electric vehicle, and belongs to the technical field of power batteries, the CTC power battery system comprises a high-low voltage connection buffer assembly, the high-low voltage connection buffer assembly is provided with a plurality of pressure relief holes, the high-low voltage connection buffer assembly is at least provided with a group of battery module assemblies matched with the pressure relief holes, and the battery module assemblies are connected with the high-low voltage connection buffer assembly. And the battery module assembly and the high-low voltage connection buffer assembly are arranged on the bottom cover plate in a sealed manner through the battery box body. According to the CTC power battery system, the battery pack and the electric vehicle, on the premise that the thermal runaway protection capacity is not reduced, the design thought continues to use a mature scheme of a non-CTC battery, part changes are small, too much tool changes are not involved, extra cost is not increased, the development time period is short, the overall mechanism is simpler and more scientific, and the cost is low. The current design requirements are met.

    本发明公开了一种CTC动力电池系统、电池包及电动车辆,属于动力电池技术领域,包括高低压连接缓冲总成,所述高低压连接缓冲总成上设有若干个泄压孔,所述高低压连接缓冲总成上至少设置有一组与泄压孔配合的电池模组总成,所述电池模组总成和高低压连接缓冲总成通过电池箱体封闭设置在底盖板上。本发明公开了一种CTC动力电池系统、电池包及电动车辆,可以在不降低热失控防护能力前提下,设计思路沿用非CTC电池的成熟方案,零部件变动小,不涉及过多工装变动、不增加额外成本且开发时间周期较短,整体机构更加简单科学,符合现在设计要求。
