The invention discloses a battery pack and a battery compartment for a new energy automobile, and a battery replacing station. The battery pack comprises a shell and a plurality of battery cells whichare arranged in the shell and connected in series and in parallel, a sealing cover is arranged at the upper part of the shell, a pressure relief device for reducing the pressure in the battery pack is arranged on the sealing cover, and the pressure relief device is connected with a trip computer on the new energy automobile through a sensing device. The battery pack is provided with the pressurerelief device and the sensing device connected with the trip computer; the state of the battery pack is monitored in real time, the pressure reducing valve is triggered to act when the battery cell ismolten and the volume is expanded due to abnormal overheating of the battery cell, and the sensing device is used for automatically alarming through the trip computer, so that a user can convenientlyhandle and move the alarmed battery pack out of the battery compartment in time, and a deflagration accident is prevented from endangering the whole vehicle; and the charging process of the battery pack is separated from the new energy automobile, electric energy is supplemented by replacing the battery pack, and sustainable driving of the new energy automobile is achieved.

    本发明公开了一种用于新能源汽车的电池包、电池舱及换电站,所述电池包包括壳体和设置在所述壳体内的多个串并联连接而成的电芯,壳体的上部设有密封盖,密封盖上设有用于降低电池包内压力的释压装置,且所述释压装置通过传感装置与新能源汽车上的行车电脑相连;其效果是:利用电池包上设置释压装置和与行车电脑相连的传感装置,实时监测电池包的状态,在电芯异常过热,导致电芯熔融,体积膨胀时,触发减压阀动作,并利用传感装置通过行车电脑进行自动报警,便于用户及时处置,将报警的电池包移出电池舱,以避免使爆燃事故危及整车;电池包的充电过程与新能源汽车本体相分离,通过更换电池包方式补充电能,实现新能源汽车可持续行驶。
