Power system of charged type hybrid power electric automobile

Abstract

The chargeable hybrid power system for cars comprises the engine, No.1 motor, No.2 motor, drive device, energy storage device, control device, and charging module. The No.1 motor is connected with the engine to start the engine and provide energy to No.2 motor, drive device realizes the forward and reverse transmission of energy through engine, output energy of the motor to vehicles, the control device composed of controller and power converter to control of flow direction and volume of the energy, storage device stores and provides energy to motor, receives charge from outside electric power network, or the receives charge from engine driving No.1 motor or energy from decelerating and braking of recycled vehicles. The charging modules realizes the connection of vehicles with the outside electric power network.

Description

technical field [0001] The invention belongs to the field of hybrid electric vehicles, and in particular relates to a power system of a rechargeable hybrid electric vehicle. The energy storage device of the power system can not only charge it with the voltage of a common power grid, but also charge it with a generator driven by the engine. The braking energy of the vehicle can be recovered to recharge it. Background technique [0002] Petroleum energy is depleting day by day, global warming, and air pollution are becoming more and more serious. Developing new alternative energy sources, improving energy conversion efficiency and saving energy are considered to be effective ways to solve or alleviate environmental pollution and ensure energy supply. Fuel engines for automobiles are a major source of energy consumption and environmental pollution. It is inevitable to develop new power to replace fuel engines. There are also more and more alternatives to fuel engines, such as ...

AI Technical Summary

Problems solved by technology

Compared with traditional fuel vehicles, the current hybrid vehicles have achieved great success in improving fuel economy and reducing exhaust emissions, obtaining excellent acceleration performance and a larger transmission range, but the hybrid vehicles The charging energy of the on-board battery comes from part of the energy output by the engine and the recovery of regenerative braking energy, which limits the advantages of motor driving and the improvement of fuel economy to a certain extent.
