Problems solved by technology

[0002] Pure electric vehicles (electric tricycles, electric four-wheelers, sightseeing cars and passenger cars) are widely used in cities or rural areas. However, existing pure electric vehicles have the disadvantage of insufficient battery capacity resulting in insufficient mileage. Therefore, car owners Often worried about insufficient power, need to charge in time

Abstract

The invention relates to a control system used for an electric vehicle. The control system comprises a controller, a motor controller, a battery management system and a battery. The controller is connected with the motor controller and the battery management system; the motor controller is connected with a driving motor; the driving motor is connected with a driving shaft through a speed reducer; the battery management system is connected with the battery; the controller is connected with a gear-shifting module through a gear position line; the controller is further connected with a range extender; and the range extender is connected with the battery and the driving motor. When battery capacity is smaller than or equal to 20%, the range extender is started so that the electric energy can be provided for driving of the whole vehicle in time, and accordingly, the endurance mileage of the electric vehicle is increased and the climbing and bearing capacity of the vehicle is improved within the capacity range of the driving motor; and starting voltage of the range extender is set, the electric energy is provided for the whole vehicle in time, and additional charge for the storage battery is performed, so that the endurance mileage of the whole vehicle is increased and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric vehicle driving equipment, and in particular to a control system for electric vehicles. Background technique [0002] Pure electric vehicles (electric tricycles, electric four-wheelers, sightseeing cars and passenger cars) are widely used in cities or rural areas.
