Multifunctional internal combustion engine for electric vehicle

Abstract

The invention relates to a multifunctional internal combustion engine for an electric vehicle. The multifunctional internal combustion engine for the electric vehicle comprises an internal combustion engine, a generator and a vehicle air conditioner; an output shaft of the internal combustion engine is connected with the generator and a rotating shaft of the vehicle air conditioner through a power switching device for driving the generator and the vehicle air conditioner; the power switching device is connected with the output shaft of the internal combustion engine for controlling one of the generator and the vehicle air conditioner; the power switching device is connected with a switching rod for realizing the switching control operation; the internal combustion engine is provided with a liquid cooling system for cooling the internal combustion engine; heat of the liquid cooling system is used for heating the internal of a vehicle; an oil storage tank is arranged on the internal combustion engine; and the generator is connected with an accumulator through a rectifier to charge the accumulator. The multifunctional internal combustion engine for the electric vehicle can charge the accumulator in the vehicle driving process; the vehicle air conditioner is driven by the internal combustion engine without consuming electric force of the accumulator; and the heat of the internal combustion engine is used for heating the internal of the vehicle, so that an air conditioner is not needed to consume electricity for heating, and the purpose of improving the cruising ability is achieved.

Description

technical field [0001] The invention relates to a multifunctional internal combustion engine for electric vehicles, which belongs to the technical field of electric vehicle power devices. Background technique [0002] With the increasing shortage of resources, the concept of energy conservation and environmental protection continues to deepen, and traditional gasoline vehicles can no longer adapt to the development of society. As a new type of energy vehicle, electric vehicles It has become a product strongly promoted by the country and increasingly accepted by the public. [0003] Due to the inherent characteristics of the electric vehicle itself, it must rely on the power stored in the battery pack to provide the power source for the motor, and the motor drives the wheels to rotate through the controller. Other electrical appliances in the car also need the power source provided by the battery pack. However, the storage capacity of the battery pack is limited. Even a larg...
