摘　　要：针对某型电动汽车的6节12V／120Ah串联的动力铅酸电池组，设计了电动汽车充电器。充电器采用两级拓扑，前级功率因数校正，后级半桥DC／DC，具有功率因数高，效率好，性能安全的优点。基于NEC78F0881单片机实现充电功能控制，采用了慢脉冲快速充电方法，达到了快速充电的效果，并使蓄电池析气量少、温升低、充电效率高，延长了电池寿命。For a certain type of electric vehicles,six 12V/120AH power lead-acid batteries in series,the car charger is designed. Charger topology using two-level topology of pre-level power factor correction and post-level half-bridge DC / DC with high power factor,high efficiency,safety performance. With charging function control of the MCU NEC78F0881 and the slow pulse fast charging method,Charger achieves a rapid charging time with less gassing, low temperature, charge efficiency, and extends battery life.
