摘　　要：本文从汽车电源管理系统功能出发,分别介绍电源管理系统组成部分,包括蓄电池电量传感器、智能发电机工作原理以及车辆电源管理系统运用。电源管理系统主要是为了保证车辆顺利的工作,根据蓄电池的SOC状态(电池传感器监测)定义不同的能量等级,在不同的能量等级下,通过能量提醒、降低用电负载或者限制关断用电负载,以降低车辆在低电量状态下的放电能量,来保证蓄电池有充足的电量用于车辆运行。另外车辆电源管理系统还具备远程监测功能,主要是车联网通信模块将车辆用电状态通过运营商网络平台以短信发送给用户手机或者用户可以自行登录手机APP账号进行查询。Starting from the functions of automobile power management system,this paper introduces the components of power management system.It includes the working principle of battery power sensor,intelligent generator and the application of vehicle power management system.The main purpose of the power management system is to ensure the smooth operation of the vehicle.Different energy levels are defined according to the SOC state of the battery(battery sensor monitoring).Under different energy levels,the discharge energy of the vehicle in the low power state is reduced by energy reminder,reducing the power load or limiting the shutdown of the power load,so as to ensure that the battery has sufficient power for vehicle operation.In addition,the vehicle power management system also has the function of remote monitoring.The main function is that the vehicle networking communication module sends the vehicle power status to the user's mobile phone by SMS through the operator's network platform,or the user can log in to the mobile app account for query.
