| Abstract: | 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. |
