Embodiment Construction

[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution of the present invention will be further described below in conjunction with specific examples.

[0019] See attached figure 1 , a battery mileage calculation and display method for an electric bicycle, comprising the following steps:

[0020] Step 1: The voltage acquisition module collects the battery voltage to determine whether the battery is fully charged;

[0021] 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);

[0022] 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 (pre...

Abstract

The invention discloses a journey continuation mileage calculation and display method for a battery of an electric bicycle. It is judged whether or not the battery is fully charged through voltage ofthe battery, running mileage is calculated through a Hall signal in the process of completing discharging of a set of fully-charged batteries, and therefore the longest journey continuation mileage ofa newest battery is calculated. The calculated longest journey continuation mileage of the newest battery is displayed to a user through a display module, and the user can know the maximum journey continuation mileage capacity of the battery.

Description

technical field [0001] The invention belongs to the technical field of electric bicycles, in particular to a method for calculating and displaying the cruising range of electric bicycle batteries. Background technique [0002] As the service life of the electric bicycle battery increases, its cruising range will gradually decay. Customers cannot know the exact cruising range of the current battery, and due to the degradation of battery performance, the power display on the dashboard will also become inaccurate. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for calculating and displaying the cruising range of an electric bicycle battery. Through the method of the invention, the accurate cruising range of the battery can be continuously updated and calculated, and the updated maximum cruising range can be displayed to the user, so that the user can know the maximum cruising capaci...
