Pure electric automobile power-driven system with a power-generation charging device

Abstract

The invention discloses a pure electric automobile power-driven system with a power-generation charging device, comprising a vehicle power-generation set composed of a motor and a power generator, a transmission device, a driving motor, a control unit, a power battery and a battery management system, wherein the motor is connected with the power generator and the driving motor is connected with the transmission device and the power generator and the driving motor are electrically connected with the vehicle control unit. The mechanical energy output from the motor is converted into the electric energy by the power generator and the converted electric energy charges the power battery or drives the vehicle by the vehicle control unit and the vehicle power-generation set is only used for generating power and not directly drives the vehicle. The vehicle-loaded power-generation set controls the start of the motor when the electric quantity of the power battery is not sufficient and drives the power generator to generate the power and charges the power battery, and charges the power battery at real time, thereby solving the problem of the prior pure electric automobile that the continual mileage is short.

Description

technical field [0001] The invention relates to a pure electric vehicle, in particular to a pure electric vehicle with its own power generation and charging device. Background technique [0002] At present, due to the pollution of fuel vehicles to the environment and the rising international oil prices, various automobile manufacturers have increased the pace of research on electric vehicles, especially small pure electric vehicles, which have become the research direction of domestic and foreign automobile companies. [0003] With the development of urban modernization, low emission, low noise, energy saving and consumption reduction have become the pursuit of various automobile manufacturers. Under this background, various electric vehicles have emerged as the times require. However, the current electric vehicles on the market are limited by battery capacity, and their mileage is generally short, so that electric vehicles can only be limited within the scope of cities or c...

AI Technical Summary

Problems solved by technology

However, the current electric vehicles on the market are limited by battery capacity, and their mileage is generally short, so that electric vehicles can only be limited within the scope of cities or communities, which seriously hinders the further promotion and popularization of electric vehicles.
