The invention relates to the technical field of new energy power systems, and discloses a power system of a multifunctional hybrid loader, which is characterized in that the output end of an engine is connected with the input end of a generator, and the output end of the generator is connected with the input end of a generator controller; the high-voltage distribution box is connected with the generator controller, the power battery box, the main drive motor controller and the hydraulic motor controller through high-voltage circuits, the power battery is connected with the power battery box through a high-voltage circuit, and the main drive motor is connected with the main drive motor controller through a high-voltage circuit. The hydraulic motor is connected with the hydraulic motor controller through a high-voltage circuit; the engine oil temperature is reduced by gradually reducing the rotating speed of the engine before the engine stops through the supercharger protection strategy, so that the supercharger is protected, and the low-temperature engine is quickly warmed up through the low-temperature quick warming strategy, so that the energy consumption is reduced, and the emission is reduced.

    本发明涉及新能源动力系统技术领域,公开了一种多功能混动装载机的动力系统,包括:发动机的输出端与发电机的输入端连接,发电机的输出端与发电机控制器的输入端连接,高压配电箱分别与发电机控制器、动力电池箱、主驱电机控制器与液压电机控制器通过高压电路连接,动力电池与动力电池箱通过高压电路连接,主驱电机与主驱电机控制器通过高压电路连接,液压电机与液压电机控制器通过高压电路连接;本发明通过增压器保护策略在发动机停机前逐渐降低发动机转速来降低机油温度,从而保护增压器,并通过低温快速暖机策略实现低温发动机快速暖机,从而降低能耗并降低排放。
