Problems solved by technology

After the car has been refitted, it basically becomes a scrap vehicle, and it has no other use except reversing and moving to the warehouse for training;
[0006] Secondly, there is room for improvement in the stall control of the motor
The high-speed resistance, high-end and low-speed of electric vehicles do not have a high utilization rate of the motor, and affect the service life of the motor. The working efficiency of the motor is similar to that of a gasoline engine, and the efficiency is not very high at low and high speeds;

Abstract

The invention relates to a control system for electric vehicles, which comprises a master control singlechip, a human-computer interface, a speed gear monitoring unit, a battery management unit and a voice module, wherein the human-computer interface is arranged at a position which is convenient to observe to display data processed by the singlechip, so that the operating state of the electric vehicles is monitored in real time. The control system can judge the speed and gears of the vehicles, prompt correct driving, improve the utilization efficiency of a motor, solve the problem of chargingand discharging and dynamic real-time monitoring of series battery packs of pure electric vehicles, and ensure the optimal operating state and service life of power batteries.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and relates to a control system for electric vehicles, which includes a motor, a motor controller, a power battery, a control, monitoring and management system for warning correct driving, and the like. Background technique [0002] The driving school coach car is a special vehicle for driving training schools. It is mainly used for the training of driving students. During the training, it is basically in an idle state. The engine of the fuel coach car is started and stopped frequently, which will emit a large amount of unburned exhaust gas, resulting in pollution. The fuel consumption is much higher than that of normal driving, and at this time, the fuel consumption is also greatly increased. [0003] The difference between a pure electric coach car and a fuel coach car is only in the power system. The power system of a pure electric coach car is a braking system composed of a battery power supp...
