The invention provides a battery thermal overload protection system. A vehicle includes an electric machine, a battery, a clamp holder, and a blade. The battery is provided with a plurality of battery cells, and the plurality of battery cells are configured to transmit electric power to the motor. The clamp holder has plates disposed at opposite ends of the plurality of cells, and a member secured to each of the plates. The member is secured to the plate under tension such that the plate applies a compressive force to the plurality of cells to reduce an internal resistance of the plurality of cells. The blade is configured to cut off the member in response to the temperature of at least one cell in the cell array exceeding a threshold to release the compressive force to increase the internal resistance of the cell array.
本公开提供“电池热过载保护系统”。一种车辆包括电机、电池、夹持固定器和刀片。所述电池具有多个电芯,所述多个电芯被配置为向所述电机输送电力。所述夹持固定器具有设置在所述多个电芯的相对端的板,以及固定到所述板中的每一者的构件。所述构件在张力作用下固定到所述板,使得所述板向所述多个电芯施加压缩力以减小所述多个电芯的内阻。所述刀片被配置为响应于电芯阵列中的至少一个电芯的温度超过阈值而切断所述构件以释放所述压缩力以增大所述电芯阵列的内阻。
