Battery management system with predictive failure analysis
First Claim
1. A battery management system comprising:
- a tag associated with a battery unit;
said tag having a unique identifier;
a battery testing device for acquiring test data on said battery unit;
said battery tester having an input for capturing said unique identifier;
a communication interface between said battery testing device and a computer network;
a database for storing battery-related data associated with said unique identifier transmitted over said computer network, said battery-related data comprising;
an ohmic test value, a baseline ohmic value, an aging factor for determining predicted failure data for said battery unit, and software for generating a predictive failure report from said battery-related data.

Abstract
The invention relates to the management of large stationary batteries. The invention is a comprehensive system and process for the management of stationary batteries that are used for backup power and are deployed in widely dispersed locations. The system is comprised of Mega-Tags, a battery testing and data acquisition device, and web-based software. The system software can automatically analyze, determine and report predicted battery failure data such as a future anticipated failure date by aging standard ohmic test values such as impedance, conductance, or resistance, by multiplying the test value by a monthly factor derived from statistical analysis and comparing the aged value to a baseline value to determine the predicted failure date.
