Abstract

The present application relates to a hybrid power system and a control method thereof. The hybrid system includes a range extender system, a power battery system and a vehicle controller. The range extender system includes the engine, clutch, generator and range extender controls. The vehicle controller is used for electrical connection with the traveling drive system. The vehicle controller is also used to receive and make the range extender system and the power battery system provide energy for the bodywork system and the driving system according to the driver's operation instructions and the status information of the vehicle and its components. The engine can directly transmit mechanical energy to the bodywork system through the clutch and the output shaft of the generator, and the generator can also work in electric mode to provide mechanical energy for the bodywork system. The hybrid power system is applied to a vehicle with a bodywork system, so that the vehicle with the bodywork system is more energy-saving and environmentally friendly than traditional fuel vehicles, and at the same time, the vehicle with the bodywork system avoids the short mileage of pure electric vehicles The problem.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a hybrid power system and a control method thereof. Background technique [0002] Some vehicles with bodywork systems not only have basic travel functions, but also have other operating functions. Such as cement tanker, bulldozer, excavator, sprinkler or crane, etc. Among them, the top loading system of the cement tank truck is the cement mixing tank system. During the process of transporting cement by vehicles, the cement mixing tank in the cement mixing tank system needs to continue to rotate. Cement mixing tanks require a constant input of mechanical energy. At the same time, the vehicle's drive system continues to work. [0003] Traditional vehicles with bodywork systems use fuel power to provide kinetic energy for the driving system and bodywork systems, causing serious environmental pollution. How to make the vehicle with bodywork system energy-saving and en...
