It is widely used in various fields such as mobile communications, laptop computers, gasoline and electric hybrid vehicles.

[0003] The automotive NiMH battery pack consists of a battery module, a sensor, a battery manager, an HV junction box assembly with a contactor, a power battery cooling fan (brushless), a maintenance switch, etc. The battery module is composed of multiple NiMH batteries. In order to ensure the daily stability of the NiMH batteries, brackets are installed on the outside of the multiple NiMH batteries. Then, the multiple NiMH battery connecting brackets are placed inside a protective shell, and a threaded hole is opened at the bottom of the NiMH battery. After the NiMH battery is placed inside the protective shell, a bolt will penetrate the protective shell and be threadedly fixed to the threaded hole at the bottom of the NiMH battery. In this way, the NiMH battery Hydrogen batteries do not shake during daily use, but this also means that when repairing and replacing nickel-hydrogen batteries, it is necessary to first remove the bolts at the bottom of all nickel-hydrogen batteries, then take out multiple nickel-hydrogen battery connecting brackets from the protective shell, and then disassemble the brackets to disperse and take out all the nickel-hydrogen batteries, and finally replace the damaged nickel-hydrogen batteries, and then reverse the above steps to complete the replacement operation of the nickel-hydrogen batteries. Even if only one battery pack is damaged, it is necessary to follow the above steps, which results in low maintenance efficiency and high cost. Based on this, a nickel-hydrogen battery pack that is easy to disassemble and repair is provided. Utility Model Content
