CHARGING METHOD FOR ADJUSTING CHARGING CURRENT
First Claim
1. A charging method for adjusting a charging current, comprising:
- using a charging system to read a present number of times of charging/discharging cycle and a rated number of times of charging/discharging cycle of a rechargeable battery;
using the charging system to compute a charging/discharging ratio between the present number of times of charging/discharging cycle and the rated number of times of charging/discharging cycle;
generating a current drop ratio from a function of the charging/discharging ratio and a percent charging current by the charging system, wherein the current drop ratio is in a range of 0 to 1; and
adjusting a charging current of the rechargeable battery by the charging system based on the current drop ratio.

Abstract
Disclosed herein is a charging method for adjusting the charging current. The charging method includes the following steps: reading a present number of times of charging/discharging cycle and a rated number of times of charging/discharging cycle by a charging system; computing a charging/discharging ratio between the present number of times of charging/discharging cycle and the rated number of times of charging/discharging cycle by the charging system; generating a current drop ratio from a function of the charging/discharging ratio and a percent charging current by the charging system, wherein the current drop ratio is in a range of 0 to 1; and the charging system adjusting the charging current of a rechargeable battery based on the current drop ratio.

6. A method for adjusting a charging current, comprising:
-
using a charging system to read a present number of times of charging/discharging cycle and a rated number of times of charging/discharging cycle of a rechargeable battery; using the charging system to compute a charging/discharging ratio between the present number of times of charging/discharging cycle and the rated number of times of charging/discharging cycle; using the charging system to determine a relationship between the charging/discharging ratio and a setting value; when the charging/discharging ratio is greater than the setting value, generating a first current drop ratio from a first function of the charging/discharging ratio and a percent charging current by the charging system, and using the charging system to adjust a charging current of the rechargeable battery based on the first current drop ratio; when the charging/discharging ratio is less than the setting value, generating a second current drop ratio from a second function of the charging/discharging ratio and a percent charging current by the charging system, and using the charging system to adjust a charging current of the rechargeable battery based on the second current drop ratio. - View Dependent Claims (7, 9, 10)
