Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 shown.

[0017] When the vehicle is running, the motor running switch 11 is closed. The clutch 19 is disengaged when the vehicle is running normally, and when the driver depresses the clutch pedal 29, the clutch 19 is engaged.

[0018] The adjustment of the running speed of the vehicle is carried out through the accelerator pedal 24 . The magnitude of the stepping amplitude of the accelerator pedal 24 is reflected by the Hall sensor 23 . The voltage value of the Hall sensor 23 is transmitted to the A / D port of the controller CPU. The controller CPU 35 controls the conduction degree of the thyristor 15 according to the voltage value of the Hall sensor 23, and controls the energizing current of the drive motor 8, so as to achieve the purpose of controlling the vehicle speed.

Abstract

The invention discloses a hydraulic energy storage braking energy regenerator for a pure electromobile, aiming at the defects that the overlarge current of the traditional pure electromobile in the processes of starting and accelerating leads to energy waste, and the cycle use of a storage battery shortens the service life. The regenerator can store kinetic energy of the pure electromobile in the braking process and release the stored kinetic energy in the processes of starting and accelerating to enable the automobile to accelerate to a certain speed. The regenerator comprises a hydraulic energy / mechanical energy transmission and conversion device, a hydraulic transmission device, a hydraulic energy storage device, a hydraulic system overvoltage protective device, a manual pressure relief device and an electric control unit. By installing the hydraulic energy storage braking energy regenerator for a pure electromobile on a pure electromobile, the cycle use life of the storage battery of the pure electromobile can be prolonged, the electrical energy can be saved, and the driving range of the electromobiles can be increased.

Description

technical field [0001] The invention relates to a braking energy regeneration device for a pure electric vehicle, in particular to a device for recovering the braking energy of a pure electric vehicle using hydraulic energy storage technology, and using the stored hydraulic energy to start the pure electric vehicle during the acceleration phase of starting A device that starts the drive motor after accelerating to a certain speed. It belongs to the technical field of electric vehicles. Background technique [0002] Due to the restriction of numerous traffic lights and traffic congestion, the small pure electric vehicles running in urban areas are forced to brake frequently, stop and start to accelerate. In order to improve energy utilization, current pure electric vehicles usually use the motor as a generator during the braking deceleration phase, and use the battery pack to absorb braking energy. However, the high-current charging of the battery pack during braking is the...
