| Abstract: | Multi-cell lithium batteries are widely used in variety of electronic equipments because they can pro- vide high voltage and current. Management for multi-cell lithium battery charging and discharging is quite important which includes cell balancing, over-current/short-circuit protection, over-temperature protection and so on. A new multi-cell lithium battery charging and discharging management based on BQ77PL900 and PIC18LF4520 is put for- ward in this paper, and the software and hardware design are illustrated in detail. Experiment results demonstrate that this circuit can successfully achieve multi-cell lithium battery charging and discharging. |
