| Abstract: | The existing defects of DC power supply and the premature failure of storage battery group are analyzed. The damage of storage battery caused by totally charging operation and its countermeasures are discussed. Individual charging is proposed to avoid overcharging and undercharging of storage battery. The alternative pathway is set for each storage battery to implement the automatic bypass of faulty storage battery. The charging module digitalization is realized without additional wiring for storage battery supervision and performance warning. Discussion and data analysis are carried out for each improvement and the measured data of prototype are given. |
