The invention relates to a lithium battery intelligent control system, vehicle-mounted equipment, a vehicle and a method, and belongs to the technical field of lithium batteries, and the system comprises a lithium battery controller which is used for sending current information of a lithium battery to a whole vehicle controller when the current output by the lithium battery is detected to be smaller than or equal to a preset current value; the whole vehicle controller is used for sending a disconnection instruction to the lithium battery controller when determining that the whole vehicle is in a high-voltage state and enters a dormant state based on the current information and the whole vehicle state information; and the lithium battery controller is also used for controlling the lithium battery to stop supplying power based on the disconnection instruction. According to the intelligent control system for the lithium battery, the MOS switch of the lithium battery can be intelligently switched off when the lithium battery cannot normally sleep due to the abnormality of the whole vehicle, so that the electric quantity loss of the lithium battery caused by the abnormal large power consumption of the whole vehicle is cut off, the sufficient electric quantity of the lithium battery can be ensured, and a guarantee for starting the vehicle is provided for a user; the situation that vehicle feed cannot be normally started due to vehicle abnormity is avoided, and the user experience is improved.
本发明涉及一种锂电池智能控制系统、车载设备、车辆及方法,属于锂电池技术领域,该系统包括:锂电池控制器,用于在检测锂电池输出的电流小于或等于预设电流值时,将锂电池的电流信息发送至整车控制器;整车控制器,用于基于电流信息和整车状态信息确定整车已下高压并进入休眠状态时,将断开指令发送至锂电池控制器;锂电池控制器,还用于基于断开指令控制锂电池停止供电。本发明提供的锂电池智能控制系统,可以在整车异常导致锂电池无法正常休眠时智能断开锂电池的MOS开关,从而切断整车异常的大功耗对锂电池的电量损耗,可以保障锂电池的充足电量,为用户提供启动车辆的保障,避免因为整车异常导致车辆馈电无法正常启动,提升用户体验感。
