Description
技术领域
本发明涉及汽车电源管理领域,特别涉及一种车载电源闭环管理系统。
背景技术
车载电源系统主要由发电机和蓄电池构成,汽车在点火时,由蓄电池向起动机供电,起动机带动发动机运转;发动机启动后,通过皮带带动发电机运转,此时发电机为整车用电设备供电。当前大部分汽车的电源系统为开环控制系统,发电机的电压不会因为蓄电池的过充或过放而变化。车载发电机始终以默认电压为整车供电,在这过程中,如果蓄电池的电量充足还继续充电的话,会造成蓄电池过充,严重会导致蓄电池寿命大大降低。另外,在汽车熄火时,蓄电池为整车的用电设备提供电能,由于放电过程也为开环控制,无法实时监控蓄电池的状态,若蓄电池的当前剩余电量不足以支持汽车的下次启动,会影响汽车的使用性能。

具体地说,所述发电机模块包括发电机和发电机调节器,发电机调节器为可调节发电机输出电压的发电机调节器。
