The invention discloses a power battery and driving equipment. The power battery comprises a high-voltage system, a low-voltage system and a module assembly, the high-voltage system comprises a plurality of soft copper bars, a plurality of hard copper bars and at least one fuse. According to the invention, high-voltage connection is carried out in a manner of combining the soft copper bar and thehard copper bar of which the lengths are smaller than the preset length, so that the technical problem of relatively large electromagnetic interference caused by a high-voltage loop formed by using along copper bar is solved; the fuse is externally arranged on the module assembly, the technical problem of maintenance inconvenience caused by the fact that the fuse is externally arranged in the power battery is solved. According to the application, the technical effects of reducing low-frequency magnetic field emission of the power battery, reducing electromagnetic interference to the battery module of the power battery and realizing convenient maintenance of the fuse are achieved.
本发明公开了一种动力电池和驾驶设备,动力电池包括高压系统、低压系统以及模组总成;高压系统包括多个软铜排、多个硬铜排以及至少一个熔断器。通过使用长度小于预设长度的软铜排和硬铜排相结合的方式进行高压连接,解决了使用长铜排构成高压回路造成的电磁干扰较大的技术问题,通过将熔断器外置于模组总成上,解决了将熔断器外置于动力电池内部导致的维护不便的技术问题。本申请实现了减小动力电池的低频磁场发射、降低了对动力电池的电池模组的电磁干扰的技术效果,以及实现了熔断器便于维护的技术效果。
