Method for checking power status of batteries
First Claim
1. A method for checking power status of a battery set having multiple batteries, the method comprising the steps of:
- determining whether the battery set is in a discharging mode;
collecting discharge data and a discharging time of each battery;
determining when the discharging mode of the battery is terminated;
comparing collected discharge data of the battery with standard discharge data to calculate a remaining power capacity of the battery;
wherein the standard discharge data are obtained from discharge data of different types of new batteries and all the standard data are saved in a standard discharge data base.

Abstract
A method of checking power status of the batteries is disclosed. New batteries are first prepared for discharge tests with different discharge rates, and the standard discharge data for different types of batteries are recorded in a data base for use in power estimation. Afterwards, the battery set installed in an uninterrupted power supply (UPS) system is connected to a monitoring device for continuous monitoring of the test discharge data and discharging time in repeated random discharge tests. The characteristic data including current output, operating temperature, and terminal voltage of the tested battery are then collected and compared with the relevant standard discharge data retrieved from the data base to produce a true estimation of the remaining power of the tested battery.
