In the process of charging and discharging,due to the difference in temperature field,the difference in self-discharge rate,and the low capacity battery in the battery pack are more likely to overcharge,undercharge or overdischarge,some weak cells in the lead-acid battery age seriously,and then accelerate the aging of the whole battery pack,shorten the life of the whole battery.To solve this problem,to develop a kind of can realize monomer battery charging system which has the function of the active equalization charging.The system has the function of isolating constant-voltage charging current limiting circuit.The cell detection unit in the system can monitor the voltage,internal resistance and temperature of the battery in real time.According to the monitoring results,the system can realize the active balanced charging of the single battery,so as to eliminate the inconsistency between the cells in the battery pack and extend the service life of the battery pack.
