Abstract
As a kind of high-energy secondary battery, mining Ni MH battery is very suitable for mine backup power because of its advantages of high capacity, high power, no pollution, long cycle life, strong charging and discharging ability and high safety. This paper mainly introduces the electrochemical reaction of Ni MH battery under normal operation, overcharge and over discharge, introduces the types and components of Ni MH battery, describes the change curve of charging and discharging terminal voltage with time under different conditions, analyzes the self discharge situation of Ni MH battery under different conditions, and analyzes the cycle life and safety of Ni MH battery. The software and hardware design of battery intelligent management and SOC estimation analysis provide the basic basis.
