Plug-in hybrid electric vehicle

Abstract

The invention aims at providing a practical plug-in hybrid electric vehicle which can save the charging time and meet the requirements of the steerability and the travelling comfort of drivers. The plug-in hybrid electric vehicle is driven by a driving motor through a speed reducer, and the driving motor is connected with a high voltage power battery by an inverter; the high voltage power battery is respectively connected with a vehicle charger, a quick charging interface and a vehicle electric generator, wherein the vehicle electric generator consists of an internal combustion engine, an electricity generating machine and the inverter; the high voltage power battery is also connected with a 12 V storage battery by a DC-DC transformer. By setting multiple charging ways, the plug-in hybrid electric vehicle can save the charging time, and can meet the requirements of the steerability and the travelling comfort of the drivers since a braking system, a steering system, an air conditioning system and the like are arranged in the vehicle; therefore, the technology is beneficial to further practicability of the plug-in hybrid electric vehicle.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicle manufacturing, and in particular relates to a plug-in hybrid electric vehicle. Background technique [0002] Among new energy vehicles, hybrid vehicles not only have the advantages of low emissions of pure electric vehicles, but also make up for the shortcoming of pure electric vehicles with short driving range, so they are getting more and more attention. [0003] From the external charging function of the energy storage device, the hybrid electric vehicle can be divided into: a plug-in hybrid electric vehicle (Plug in Hybrid Electric Vehicle, PhEV for short) and a non-external charging hybrid electric vehicle. The plug-in hybrid electric vehicle is between the pure electric vehicle and the conventional hybrid electric vehicle, and has the following characteristics: the pure electric mode is used for a short mileage, and the auxiliary mode of the internal combustion engine is used...

AI Technical Summary

Problems solved by technology

The plug-in hybrid electric vehicle is between the pure electric vehicle and the conventional hybrid electric vehicle, and has the following characteristics: the pure electric mode is used for a short mileage, and the auxiliary mode of the internal combustion engine is used for a long mileage. Together with the generator, it forms a generator set to supplement the energy of the battery; this kind of vehicle can use the external public grid to charge the vehicle power battery in a balanced manner, reducing the number of times to go to the gas station to refuel, and greatly reducing the dependence of the vehicle on oil; in addition, the electricity price It is cheaper than fuel and improves the economy of the whole vehicle. At present, the development of plug-in hybrid electric vehicles is in its infancy, and the technology is not yet mature.
