Electric vehicle energy recovery and control system based on wheel driving

Abstract

The invention relates to an electric vehicle energy recovery and control system based on wheel driving. The system comprises an energy recovery start-stop control module mounted and fixed on an electric vehicle frame, a wheel speed sensor used for testing the rotating speed of wheels of the electric vehicle and arranged on the energy recovery start-stop control module, a speed regulation control module used for processing wheel rotating speed signals output by the wheel speed sensor, a generator set control module used for receiving the vehicle rotating speed signals processed by the speed regulation control module and determining the working mode of a generator set, and a battery pack intelligent coordination control module used for controlling the working mode of a power battery pack module of the electric vehicle. The system is used for continuously improving the energy recovery quality, so that the endurance mileage of the electric vehicle is continuously improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle energy recovery, relates to an electric vehicle capacity recovery technology, in particular to a wheel-driven electric vehicle energy recovery and control system. Background technique [0002] With the development of the times and the improvement of people's living conditions, the automobile industry has become very popular in recent years. However, the popularization of automobiles has also brought serious energy and environmental problems. Energy conservation and environmental protection have become the themes of automobile technology development. In the past ten years, the technology of electric vehicles and related components has been greatly developed. [0003] At present, the cruising range of electric vehicles is relatively short due to the constraints of battery technology, which is the main factor for the slow adoption of electric vehicles. The disadvantage of improving the bat...

AI Technical Summary

Problems solved by technology

The disadvantage of improving the battery life of electric vehicles by recovering the energy in the braking process is that the recovered energy is very limited and not continuous, and cannot meet the long-distance battery life requirements of electric vehicles.

Due to the limitation of cruising range of electric vehicles, unreasonable layout of charging piles, occupied charging piles, low overall utilization rate, long charging time and other problems, as well as problems caused by existing infrastructure in the operation process, all affect Factors driving the popularity of electric vehicles
