Problems solved by technology

[0002] At present, the known electric vehicle adjusts the driving speed of the electric vehicle through the right-hand speed control handle, and the manual speed control handle slowly rotates inward, and the electric vehicle starts slowly; however, most people who drive electric vehicles have no practical training. For those with a driver's license, it is difficult to precisely adjust the speed control handle when turning the speed control handle and starting the car.
Ordinary people are used to turning the speed control to a large angle to start the electric car, but under the weight of the car and people and the limited power factor of the motor, it cannot start at a high speed at once, and the output current of the battery is too large, resulting in excessive power consumption. Reduced driving range and battery life on a single charge

Embodiment Construction

[0010] In the figure, the input terminal (7) of the speed regulation control line of the electric vehicle controller (6) is connected in series with a Zener diode (5), and its voltage regulator value is half of the control voltage of the speed regulator (2.5V); The other end of the voltage diode (5) is connected to the Hall element speed control output line in the left-hand speed control handle control line (3). and wiring remains unchanged. The basic principle of the left-hand speed control handle (4) and the right-hand speed control handle (1) is the same, the difference is that the left-hand speed control handle (4) is based on the existing right-hand speed control handle (1), and the magnetic The steel is taken out and installed in a reverse direction of 180°. The spring in the left-hand speed control handle (4) and the spring in the right-hand speed control handle (1) rebound in the opposite direction, which changes the Hall element in the speed control handle and the mag...

Abstract

One left hand controlled speed regulating handlebar is increased to electric bicycle to limit the starting power consumption, increase the running mileage after once recharging and increase the service life of accumulator. The left hand controlled speed regulating handlebar is the same as one right hand controlled speed regulating handlebar principally, but has only one half of the controlled voltage. The left hand controlled speed regulating handlebar is applied mainly for the initial speed regulating control within the motor power of one half the maximum power, and after the speed reaches 5-10 KPH, the right hand controlled speed regulating handlebar is replaced for speeding.

Description

1. The technical field [0001] The invention relates to a speed regulating handle of an electric vehicle, in particular to a left-hand control speed regulating handle which prevents the starting power consumption of the electric vehicle from being too large, shortens the driving distance of a single charge and protects the service life of the battery. 2. Background technology [0002] At present, the known electric vehicle adjusts the running speed of the electric vehicle through the right-hand speed control handle, the manual speed control handle is slowly turned inward, and the electric vehicle starts slowly; however, most people who drive electric vehicles do not have actual training For people with a driver's license, it is difficult to accurately adjust the speed control when turning the speed control handle and the start of the car. Most people are accustomed to turning the speed control to a large angle to make the electric car start, but under the weight of the car an...
