The invention relates to a power battery charging control method and device, vehicle-mounted equipment and a vehicle. According to the method, the current remaining oil quantity of the vehicle and the current remaining electric quantity and the current voltage of a power battery are obtained, and if the current remaining electric quantity is smaller than a preset remaining electric quantity threshold value, the power battery is charged based on the current remaining oil quantity and the oil-electricity conversion rate; determining the electric quantity increment of the power battery, and if the electric quantity increment is greater than or equal to the preset charging quantity of the power battery and the current voltage is greater than or equal to the starting voltage of the engine, controlling the engine to start and charging the power battery; the power battery is protected in a charging mode, the situation that the power battery is completely discharged due to the internal resistance of the power battery is avoided, meanwhile, the situation that when the electric quantity increment is smaller than the preset charging quantity of the power battery, an engine is frequently started, but effective charging cannot be conducted on the power battery is avoided, the charging and discharging performance of the power battery can be kept, and the charging and discharging efficiency is improved. Therefore, the service life of the power battery is prolonged.

    本申请涉及一种动力电池补电控制方法、装置、车载设备及车辆,该方法通过获取车辆的当前剩余油量、动力电池的当前剩余电量和当前电压,若当前剩余电量小于预设剩余电量阈值,则基于当前剩余油量、油电转化率,确定动力电池的电量增量,若电量增量大于或等于动力电池的预设补电量,且当前电压大于或等于发动机的启动电压,则控制发动机启动并为动力电池补电;本申请通过补电方式保护动力电池,避免动力电池由于自身内阻而导致完全放电的情形,同时,避免电量增量小于动力电池的预设补电量时,频繁启动发动机却不能为动力电池进行有效补电的情形,有利于动力电池充放电性能的保持,从而延长动力电池的使用寿命。
