Abstract

The invention relates to a power assembly system for a plug-in hybrid electric vehicle, which comprises a front shaft driving assembly, a rear shaft driving assembly, a high-voltage power battery. The front shaft driving assembly mainly comprises an engine, a gearbox and a front shaft motor, wherein the front shaft motor is connected with the engine. The rear shaft driving assembly mainly comprises a rear shaft reducer and a rear shaft motor connected with the rear shaft reducer; and the high-voltage power battery is controlled by a battery manager and is connected with the front shaft motor and the rear shaft motor through a first inverter and a second inverter for supplying power to and charging automobiles working under different conditions. The power assembly system for the plug-in hybrid electric vehicle has a characteristic of simple structure and is more suitable for industrial production in terms of vehicle control and system integration.

Description

technical field [0001] The present invention relates to the field of hybrid electric vehicles, and more specifically, the present invention relates to a power assembly system of a plug-in hybrid electric four-wheel drive vehicle. Background technique [0002] Before the industrialization of pure electric vehicles, hybrid electric vehicles are a type of vehicle that can not only meet energy conservation and environmental protection, but also realize large-scale industrialization. Hybrid vehicles are classified into three categories according to their degree of dependence on electric energy: namely, mild hybrid, moderate hybrid and strong hybrid. [0003] At present, among many hybrid electric vehicle models, a full hybrid electric vehicle is one of the models used in the development of the transition from hybrid electric vehicles to pure electric vehicles. [0004] The strong-hybrid hybrid electric vehicle means that the ratio of the rated power of the electric motor to the ...
