The invention relates to the technical field of electric automobiles, in particular to an automobile with a battery airtightness detection function and a battery airtightness detection method, and the automobile with the battery airtightness detection function comprises a battery pack, an inflation part, a pressure maintaining part, a detection part and a control part. The battery pack is provided with an anti-explosion valve, the pressure maintaining part and the anti-explosion valve are oppositely arranged, the inflation part, the pressure maintaining part and the detection part are all in communication connection with the control part, and the inflation part is communicated with the battery pack. When the control part triggers a detection instruction, the pressure maintaining part can apply pressure for pressing the explosion-proof valve into the battery pack, the inflation part can inflate the battery pack, and the detection part can feed back the real-time pressure of the battery pack to the control part. According to the automobile with the battery airtightness detection function and the battery airtightness detection method, the automobile can detect the airtightness of the battery pack in real time, the procedure that the battery pack needs to be disassembled and assembled in the airtightness detection process is avoided, and the airtightness detection convenience and operability of the battery pack are improved.

    本申请涉及电动汽车技术领域,尤其是涉及一种具备电池气密性检测功能的汽车及电池气密性检测方法,具备电池气密性检测功能的汽车包括电池包、充气部、保压部、检测部和控制部。上述电池包设置有防爆阀,保压部与防爆阀相对设置,充气部、保压部和检测部均与控制部通信连接,充气部与电池包连通。当控制部触发检测指令,保压部能够对防爆阀施加压入电池包的压力,且充气部能够向电池包内充气,检测部能够向控制部反馈电池包的实时压力。根据本申请提供的具备电池气密性检测功能的汽车及电池气密性检测方法,使得汽车能够实时检测电池包的气密性,避免了气密性检测过程中需要对电池包进行拆装的工序,提高检测电池包的气密性便捷性和可操作性。
