The invention relates to a vehicle-mounted battery charging method and device, and a vehicle. The method is applied to the vehicle, the vehicle is internally provided with the vehicle-mounted battery and a charger used for being connected with external charging equipment, and the charger is connected with the vehicle-mounted battery. The method comprises the following steps of after the charger is connected with the external charging equipment, detecting the duration of the voltage value of a high voltage output by the charger and the duration of the voltage value of the low voltage output by the charger in sequence to determine whether the power supply of the charger is stable or not; and after determining that the power supply of the charger is stable, charging the vehicle-mounted battery based on the output power of the charger. By means of the vehicle-mounted battery charging method and device, the time for charging the vehicle-mounted battery can be determined by detecting the duration of the voltage values of the high voltage and the low voltage output by the charger and the power, the conditions that the voltage is unstable and the output power of the charger is low in the charging process are avoided, and the charging speed is increased while the charging stability and safety are guaranteed.

    本公开涉及一种车载电池的充电方法、装置和车辆,该方法应用于车辆,该车辆中设置有车载电池和用于连接外接充电设备的充电机,该充电机与该车载电池连接,包括:在该充电机与该外接充电设备连接后,依次检测该充电机输出的高电压的电压值的持续时长和该充电机输出的低电压的电压值的持续时长,以确定该充电机的供电是否稳定;在确定该充电机的供电稳定后,基于该充电机的输出功率,进行该车载电池的充电操作。能够通过检测充电机输出的高电压和低电压的电压值的持续时长,以及功率确定为该车载电池进行充电操作的时机,避免充电过程中出现电压不稳定和充电机输出功率较低的情况,在保证充电的稳定性和安全性的同时,提高了充电速度。
