Embodiment Construction

[0032] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] An electric bicycle with energy recovery function, the processing method flow chart is as follows figure 1 As shown, the main control chip MCU obtains the slope information of the electric bicycle through the gyroscope chip, and the slope information indicates that the electric bicycle is driving on a downhill, an uphill, and a flat surface.

[0034] When the slope information indicates that the electric bicycle is going downhill or driving on flat ground, and the main control chip obtains the brake pedal output braking information through the brake signal acquisition circuit, and if the brake pedal is not stepped on, the electric bicycle will run at the original speed , if the driving speed of the electric bicycle is greater than the predetermined speed obtained through the speed acquisition circuit, the main control chip obtains the...

Abstract

The invention discloses an electric bicycle with an energy recovery function, and relates to the field of electric bicycles. The method includes: a main control chip obtains slope information through a gyroscope chip; When the control chip obtains the braking information output by the brake pedal, if the driving speed of the electric bicycle is greater than the predetermined speed, the main control chip respectively obtains the output power of the motor and the remaining power of the battery, and performs energy recovery according to the output power of the motor and the remaining power of the battery; when the slope information When the electric vehicle is instructed to go downhill and the signal from the brake signal acquisition circuit is not received, if the driving speed is greater than the predetermined speed, the main control chip recycles the information according to the speed regulation; when the slope information indicates that the electric bicycle goes uphill, the electric bicycle Driving at the original speed can ensure the comfort of the vehicle when it is running, and at the same time can maximize the recovered energy and reduce the energy consumption of the vehicle.

Description

technical field [0001] The invention relates to the field of electric bicycles, in particular to an electric bicycle with energy recovery function. Background technique [0002] People cannot live without a variety of transportation vehicles. Electric bicycles are a common transportation tool. During the driving of electric bicycles, braking is essential. Electric bicycles brake through friction between objects. It will convert the kinetic energy of the vehicle into heat energy and consume energy to achieve the purpose of reducing the speed of the vehicle. At present, an important reason that restricts the rapid development of electric bicycles is the battery life problem. [0003] Braking energy recovery is one of the ways to improve battery life of electric bicycles. It can convert the braking energy generated by electric bicycles during braking into electric energy of the battery for storage, and then use the electric energy in the battery for traction. During driving, t...
