The invention discloses a battery thermal management method, a control device, a vehicle thermal management system and a vehicle. The control device firstly determines the heat management demand level of the battery, then selects the target battery cold plate from the multiple battery cold plates according to the heat management demand level, and then controls the heat exchange working medium of the vehicle heat management system to flow through the target battery cold plate. The vehicle heat management system comprises a battery and a plurality of battery cold plates, the heat management requirement level corresponds to the refrigeration requirement or the heating requirement, and a heat exchange working medium is used for conducting heat exchange with the battery when flowing through the target battery cold plate. According to the scheme, the battery temperature can be finely controlled, the service life of the battery is prolonged, and the endurance mileage of the battery is increased.
