The invention discloses a vehicle storage battery charging fault detection system, a vehicle and a control method. The vehicle storage battery charging fault detection system comprises a high-voltagepower supply, a low-voltage power supply, a DC/DC converter, a battery sensor and a vehicle control unit. The DC/DC converter is connected between the high-voltage power supply and the low-voltage power supply so as to convert high-voltage current output by the high-voltage power supply into low-voltage current capable of charging the low-voltage power supply, and the low-voltage current is used for charging the low-voltage power supply; the battery sensor is used for collecting power supply information of the low-voltage power supply; and the vehicle control unit is connected with the DC/DC converter and the battery sensor so as to receive converter information from the DC/DC converter and the power supply information of the battery sensor and judge whether the low-voltage power supply has a charging fault or not according to the power supply information and/or the power supply information. The vehicle storage battery charging fault detection system can accurately detect the chargingstate of the low-voltage power supply so as to avoid driving danger.

    本发明公开了一种车辆蓄电池充电故障检测系统和车辆以及控制方法,其中车辆蓄电池充电故障检测系统包括:高压电源、低压电源、DC/DC转换器、电池传感器和整车控制器。DC/DC转换器连接在高压电源与低压电源之间,以将高压电源输出的高压电流转换为可为低压电源充电的低压电流,并利用低压电流为低压电源充电;电池传感器用于采集低压电源的电源信息;整车控制器与DC/DC转换器以及电池传感器相连,以接收来自DC/DC转换器的转换器信息以及电池传感器的电源信息,以根据电源信息和/或电源信息判断低压电源是否发生充电故障。该车辆蓄电池充电故障检测系统能够准确的检测出低压电源的充电状态,以避免发生驾驶危险。
