Improvement strategy of overcharging characteristics of a new type lithium iron phosphate battery in substation

In order to solve the hidden trouble for long-term overcharging condition of lithium iron phosphate batteries, it is urgent develop protective batteries. A strategy combining autonomous equalization technology and passive proposed in this paper improve characteristics certain proportion oxidizing reductant added electrolyte ordinary battery. And a comparative test conducted between conventional battery module self-equalization continuous state. The results show that comprehensive has reduced voltage difference cells significantly, single cell small process, so as maintain safe level.
