Electric vehicle control system

Abstract

The invention discloses an electric vehicle control system. A main storage battery and an auxiliary storage battery are arranged on an electric vehicle, and electric energy generated during running of a micro generator is output and stored in the auxiliary storage battery after being rectified and voltage-stabilized through a rectifying and voltage-stabilizing circuit board. The electric vehicle control system comprises an electronic compass and an electric vehicle controller, wherein the main storage battery, the auxiliary storage battery and the electronic compass are communicated with the electric vehicle controller; in the riding process of the electric vehicle, the electric vehicle controller is used for processing the running state information of the electric vehicle, the main storage battery and the auxiliary storage battery, controlling the power supply states of the main storage battery and the auxiliary storage battery specific to a motor and adjusting the running of the motor. According to the electric vehicle control system, energy generated by upward and vertical vibration in the riding process of the electric vehicle is used for driving the micro generator to run in order to generate electric energy, the use of the storage batteries is optimized, and the service lives and the running mileage of the batteries are prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles. Background technique [0002] Electric vehicles have now entered the homes of ordinary people. The riding state of electric vehicles in the existing market is completely controlled by the rider according to the road conditions and the operating status of the electric vehicle itself. Due to the difference in the perception of the rider, the control is not accurate enough. Therefore, the running state of the electric vehicle and the riding comfort are not good enough. [0003] Electric vehicles have different requirements for power supply under different operating conditions. For example, when starting and climbing, the motor needs to increase the torque. At this time, the power supply needs to maintain a stable high-current output. The current is enough, but when going downhill, the motor decelerates and the motor torque decreases, so a larger current is not needed. However, the curren...

Problems solved by technology

However, the current electric vehicles do not specifically consider these factors, which affects the service life and mileage of the battery.

[0004] In addition, in the process of riding an electric vehicle, vibration is inevitable, especially in some remote areas such as rural areas and mountainous areas, where the road conditions are poor, the vibration will be greater, and the riding comfort will be greatly reduced.
