The first-stage charging current magnitude and the number of stage for charging current were researched. The results show that if the battery is charged at 0.5 C for the first stage and at constant current for the fourth and fifth stage, then it can be full charged in less than 150 min, and cycle life...

A new method of multi-stage constant charge for valve-regulated lead-acid (VRLA) battery system of electric bicycle has been studied in this paper. The first-stage charging current magnitude and the number of stage for charging current were researched. The results show that if the battery is charged at 0.5 C for the first stage and at constant current for the fourth and fifth stage, then it can be full charged in less than 150 min, and cycle life can reach 250 times. Compare to the constant-voltage limitary-current charging method, multi-stage constant-current charging method can shorten charging time, reduce temperature raising, lessen water losing, and longer cycle life. In addition, multi-stage constant-current charging eliminats the sulfuration of grids caused by unsuited charging, and recovers the capacity of the battery. Investigation of the degradation mechanism of VRLA batteries reveal that the conditions of multi-stage constant-current charging suppress softening of cathode active materials and sulphating of anode active materials .
