Power system with hybrid power for sanitation vehicle

The utility model relates to a power system with hybrid power for a sanitation vehicle. The power system comprises a running power system and a vehicle-mounted operation device, wherein the running power system is a hybrid power system, the running power system comprises an electric motor which is connected with the vehicle-mounted operation device in a mechanical transmission manner, and the electric motor is not directly connected with a driving bridge. Through the adoption of the power system disclosed by the utility model, the sanitation vehicle can run and perform sanitation operation at the same time, so that not only time but also energy sources are saved. When the electric quantity of a power battery is larger than a set value, the sanitation vehicle is in a pure electric mode, and the power battery provides all energy needed by the running and the operation of the sanitation vehicle. When the electric quantity of the power battery is smaller than the set value, clutches are combined, and an engine also drives the vehicle-mounted operation device. Whether the sanitation vehicle is under the pure electric mode or the hybrid power mode is controlled according to the electric quantity of the power battery, so that the power demands of the sanitation vehicle during operation are satisfied.
