Method of measuring and displaying actual quantity of electricity of rechargeable battery being charged by external power source via charger
First Claim
1. A method of measuring and displaying an actual quantity of electricity of a rechargeable battery being charged by an external power source via a charger, the method comprising the steps of:
- (a) issuing a predetermined power out signal from said charger to temporarily disable the external power source;
(b) sending a signal indicating the actual quantity of electricity of said rechargeable battery as feedback to said charger in response to said disabled external power source; and
(c) configuring said charger to have a predetermined reference voltage so as to compare said reference voltage with a voltage of said feedback actual quantity of electricity of said rechargeable battery to obtain a voltage ratio with respect to the actual quantity of electricity of the rechargeable battery, and issue a display signal to a display for displaying a measurement based on said voltage ratio.

Abstract
A method of measuring and displaying the actual quantity of electricity of a rechargeable battery being charged by an external power source via a charger. The method includes issuing a power out signal from the charger to temporarily disable the power source; sending a signal indicating the actual quantity of electricity of the battery as feedback to the controller in response to the disabled power source; and configuring the controller to have a reference voltage so as to compare the reference voltage with a voltage of the feedback actual quantity of electricity of the rechargeable battery to obtain a voltage ratio, and issue a display signal to a display for displaying a correct measurement based on the voltage ratio.
