The invention discloses a vehicle-mounted charging system control method, device and equipment for an engineering vehicle and a medium, an AC/DC (alternating current/direct current) vehicle-mounted charging system is additionally arranged on a whole machine, and a charging mode during operation is realized on the basis of a pure battery mode. The system dynamically adjusts the AC/DC charging power according to factors such as the battery heating requirement, the SOC residual electric quantity and the intention of a driver, and on the premise that the whole machine operation endurance requirement is met, the size of a whole machine battery is reduced, and the whole machine cost is reduced. The endurance working time of the electric engineering machinery is prolonged. Therefore, the size of the battery is reduced, and the cost of the whole vehicle is reduced. Automatic working mode selection is achieved, the power requirement for battery preheating under the low-temperature condition is met, and meanwhile the control algorithm can achieve charging with the optimal charging efficiency. Strategy parameters only need to be adaptively adjusted according to battery parameters and AC/DC parameters, and strategy transplantation and engineering application are facilitated.
