The invention discloses a vehicle-mounted photovoltaic system, a control method and a vehicle, and belongs to the technical field of automobiles, the vehicle-mounted photovoltaic system comprises a high-voltage power battery, a vehicle-mounted bidirectional DC/DC converter, a high-voltage bus relay, a low-voltage storage battery, a battery management unit BMS, a vehicle control unit VCU, a vehicle energy management unit EEM and a vehicle-mounted photovoltaic assembly, and vehicle energy management is achieved through cooperative control of the BMS, the VCU, the EEM and DC/DC. The electric energy emitted by the photovoltaic module is efficiently utilized; the photovoltaic module is used for generating power to supplement the standby consumed electric energy of the whole vehicle; and intelligent management of photovoltaic energy is achieved through real-time monitoring and control, after the vehicle stops, electric energy emitted by the photovoltaic module preferentially supplements the electric quantity of the 12V storage battery, and when the SOC of the storage battery is larger than a set threshold value, bidirectional DC/DC boost conversion is started, the electric energy emitted by the photovoltaic module is transmitted into the power battery, and energy supplementation of the power battery is achieved.
