Extended range pure electric automobile system

Abstract

The invention discloses an extended range pure electric automobile system. A complete automobile controller, a control power supply and a DC / DC electric pressure converter are connected in turn; a brake system is connected with a driving motor; a motor controller, the driving motor and a speed change and transmission mechanism are connected in turn; the DC / DC electric pressure converter and a vehicle-mounted charger are connected with a power battery pack; an extended range power supply is connected with the vehicle-mounted charger, the power battery pack and an energy management center; the energy management center is connected with the power battery pack; and the complete automobile controller, the vehicle-mounted charger, the energy management center, an operation control mechanism, the motor controller and the speed change and transmission mechanism are connected through a communication bus. The extended range pure electric automobile system has the advantages of effectively prolonging the full charge endurance of the electric automobile, not needing a fuel generator or a fuel storage device and fulfilling the aims of purely and electrically extending the range, optimizing and prolonging the service life of the power battery pack, improving the reliability and safety performance of the complete automobile, and the like.

Description

technical field [0001] The invention relates to an extended-range pure electric vehicle system. Background technique [0002] Pure electric vehicles have problems such as high battery manufacturing costs, short mileage due to the limitation of their own weight, inconvenient charging, and high failure rates leading to safety hazards. These problems cannot be solved in a short time, and it is difficult to truly cooperate The competition of traditional automobiles will greatly affect its position in the market. In this context, all major automobile countries in the world are conducting research and development and competition of a new generation of electric vehicles, and range-extended electric vehicles are recognized as one of the mainstream technical directions for the development of electric vehicles. [0003] In the existing range-extended electric vehicles, the battery can be charged by the mains for driving, and within a certain mileage range, it is a pure electric opera...

AI Technical Summary

Problems solved by technology

Due to the unsatisfactory cycle life and the inability to charge, metal-air batteries cannot currently be used as mainstream electric vehicle power batteries.
