Embodiment 1

[0018] See attached figure 1 , an intelligent and dynamic calculation method for electric bicycle battery mileage is as follows:

[0019] Step 1: The voltage acquisition module collects the battery voltage to determine whether the battery is fully charged;

[0020] Step 2: If the battery is fully charged, first reset the last calculated mileage to zero, and then start to calculate the mileage again (calculate the mileage through the Hall signal of the motor);

[0021] Step 3: In the process of calculating the mileage, it is necessary to determine whether the start switch of the electric bicycle is closed. If the start switch of the electric bicycle is closed, it is necessary to further determine whether the closure exceeds the set time (preferably set to 7 days, because even if the start switch of the electric bicycle is closed If the motor is not running, the battery power of the electric bicycle will also be lost, so it is necessary to set an appropriate time to more accura...

Embodiment 2

[0026] Application of the battery cruising range calculation method described in Embodiment 1: the latest maximum battery cruising range calculated in Embodiment 1 is displayed to the user through the display module (display instrument), so that the user can know the maximum cruising range capability of the battery in time (The maximum cruising range capability of the battery refers to the maximum driving kilometers when the battery is fully charged).

Embodiment 3

[0028] Application of the battery mileage calculation method described in Embodiment 1: the latest mileage calculated in Embodiment 1 is used as the reference mileage, and the value of the reference mileage minus the real-time mileage of the electric bicycle is displayed on the display instrument, so that the user can Know the remaining driving kilometers of the battery in real time.

Abstract

The invention discloses an intelligent and dynamic calculation method for the endurance mileage of electric bicycle batteries. The method judges whether batteries are fully charged or not through battery voltage, and calculates the driving mileage of a group of fully charged batteries till the completion of battery discharge through a Hall signal. Through the method, the accurate maximum endurancemileage of the batteries can be continuously updated and calculated.

Description

technical field [0001] The invention belongs to the technical field of electric bicycles, in particular to an intelligent and dynamic calculation method for battery cruising range of electric bicycles. Background technique [0002] As the service life of the electric bicycle battery increases, its cruising range will gradually decay, and customers cannot know the exact maximum cruising range of the current battery. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide an intelligent and dynamic calculation method for the cruising range of electric bicycle batteries. Through the method of the invention, the accurate cruising range of the battery can be continuously updated and calculated. [0004] The present invention is achieved through the following technical solutions: [0005] An intelligent and dynamic calculation method for electric bicycle battery mileage is as follows: [0006] Step 1:...
