The invention relates to a vehicle-mounted storage battery charging method and device and a vehicle. The method comprises the steps that the working duration of a DCDC of a vehicle in the working state during the high-voltage power supply period is recorded, and the working state is the state that the DCDC converts high voltage into low voltage and charges a vehicle-mounted storage battery; according to the recorded time length and a preset corresponding relation, the dormancy time length of dormancy of the vehicle after high-voltage power supply is determined, the determined dormancy time length is sent to the T-box, and the preset corresponding relation is the relation between the working time length and the dormancy time length; if the vehicle is awakened by the T-box, the vehicle is controlled to carry out next high-voltage power supply, and the DCDC is controlled to enter a working state, and if the vehicle enters a dormant state, the T-box carries out timing and awakens a vehicle control unit VCU when the dormant duration received for the last time in the high-voltage power supply period is reached. Therefore, the vehicle can be awakened to charge the storage battery at a proper time after the vehicle is dormant without detecting the electric quantity of the vehicle-mounted storage battery.

    本公开涉及一种车载蓄电池充电方法和装置、车辆。方法包括:记录本次高压供电期间车辆的DCDC处于工作状态的工作时长,工作状态为DCDC将高压转换为低压,为车载蓄电池充电的状态;根据所记录的时长和预定的对应关系确定车辆在本次高压供电之后进行休眠的休眠时长,并将所确定的休眠时长发送给T‑box,预定的对应关系为工作时长与休眠时长二者之间的关系;若被T‑box唤醒,则控制车辆进行下次高压供电,并控制DCDC进入工作状态,若车辆进入休眠状态,则T‑box进行计时,并在到达本次高压供电期间最后一次接收到的休眠时长时唤醒整车控制器VCU。这样,不需要检测车载蓄电池的电量,就能够在车辆休眠后的合适的时机唤醒车辆对蓄电池充电。
