The invention discloses a low-power-consumption automatic storage battery charging device and method for a vehicle, and relates to the technical field of electric automobiles, the automatic storage battery charging device comprises a storage battery charging identification module, a charging loop isolation control module, a CAN/LIN communication module and a loop isolation execution module, the loop isolation execution module can isolate or close a low-voltage loop of the whole vehicle, after isolation, a power supply loop supplies power to an electrical load which is strongly related to the electricity supplementing function and cuts off power supply to an electrical load which is not related to the electricity supplementing function, and through isolation control of the power supply loop, low-voltage power consumption is reduced to the maximum extent, electricity consumption of a power battery is reduced in total, and the endurance mileage is increased; the electrical load of the isolation loop is distinguished, the load irrelevant to the electricity supplementing function, safety, data uploading, door opening and unlocking and the user memory function is all isolated outside the electricity supplementing loop, control execution and logic recovery are isolated, and the problem of false alarm faults caused by isolation outage of the controller is avoided.
本发明公开了一种车辆低电耗的蓄电池自动补电装置及自动补电方法,涉及电动汽车技术领域,所述蓄电池自动补电装置包括:蓄电池补电识别模块、补电回路隔离控制模块、CAN/LIN通讯模块和回路隔离执行模块,回路隔离执行模块可将整车低压回路隔离或闭合,隔离后供电回路给补电功能强相关电气负载供电,与补电功能不相关的电气负载断开供电,通过供电回路的隔离控制,最大化的减少低压电耗,总而减少动力电池的电量消耗,增加续航里程;区分隔离回路的电气负载,与补电功能、安全、数据上传、开门解锁、用户记忆功能不相关的负载全部隔离在补电回路之外,隔离控制执行及恢复逻辑,避免控制器由于隔离断电导致的误报故障问题。
