The invention provides an intelligent control method and system for double low-voltage batteries of a whole vehicle, and the method comprises the steps: obtaining a vehicle instruction, and judging whether the vehicle instruction is a whole vehicle power-on instruction or not; if yes, the bistable magnetic latching relay is controlled to be attracted, so that the connection of the refitted storage battery loop and the starting storage battery loop is achieved; obtaining the residual electric quantity of the starting storage battery sensed by the storage battery sensor, and judging whether the residual electric quantity is lower than a threshold value or not; and if not, the bistable magnetic latching relay is controlled to be disconnected, specifically, an additional storage battery is additionally arranged and specially used for supplying power to the refitted equipment, the two power supply loops are connected through a double-low-voltage storage battery relay, and the relays are controlled to be disconnected or connected according to the running state of the vehicle, so that the starting battery is prevented from being damaged by the refitted equipment, and meanwhile the starting battery is protected. Therefore, timely charging of the feed storage battery is realized, and the problem that the vehicle cannot be started due to feed of the refitted vehicle battery equipment is effectively solved.
本发明提供了一种整车双低压电池智能控制方法及系统,该方法通过获取车辆指令,并判断车辆指令是否为整车上电指令;若是,则控制双稳态磁保持继电器吸合,以使改装蓄电池回路和启动蓄电池回路的连接;获取蓄电池传感器感应到的启动蓄电池的剩余电量,并判断剩余电量是否低于阈值;若否,则控制双稳态磁保持继电器断开,具体的,增加一个额外的蓄电池专用于改装设备供电,两个供电回路由双低压蓄电池继电器连接,根据车辆运行状态控制切断或连接继电器,从而在规避改装设备对启动电池造成损害的同时,实现对馈电的蓄电池进行及时充电,有效解决了改装车辆电池设备馈电,导致车辆无法启动的问题。
