The invention discloses a storage battery charging method and a vehicle, and belongs to the technical field of vehicles. The method is applied to a vehicle and comprises the steps that a voltage detector obtains power supply voltage in real time, generates a first wake-up signal and a fault signal on the basis that the power supply voltage is smaller than a first threshold value, sends the first wake-up signal to a controller and a battery management system and sends the fault signal to the battery management system. The controller and the battery management system respond to the received first wake-up signal and are converted from the low-power-consumption state to the working state. And the battery management system responds to the received fault signal, detects the state of the storage battery, generates a power supply signal, and sends the power supply signal to the controller. And the controller generates a charging instruction based on the charging signal, and sends the charging instruction to the battery management system. And the battery management system controls the power battery to charge the storage battery based on the charge instruction. By adopting the method, the storage battery can be charged more timely.

    本申请公开了一种蓄电池补电方法及车辆,属于车辆技术领域。该方法应用于车辆,该方法包括:电压检测器实时获取供电电压,基于供电电压小于第一阈值,生成第一唤醒信号和故障信号,并将第一唤醒信号发送至控制器和电池管理系统,将故障信号发送至电池管理系统。控制器和电池管理系统响应于接收到第一唤醒信号,均从低功耗状态转为工作状态。电池管理系统响应于接收到故障信号,对蓄电池的状态进行检测,生成补电信号,并将补电信号发送至控制器。控制器基于补电信号,生成补电指令,并将补电指令发送至电池管理系统。电池管理系统基于补电指令,控制动力电池对蓄电池进行补电。采用该方法,可以更及时地对蓄电池进行补电。
