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.
