Abstract

A battery pack and a method of operating a battery system. The battery pack includes a rechargeable battery, an analog-to digital converter, and a processor. The analog-to digital converter is able to convert both positive and negative analog signals to digital signals; and, in use, the converter receives analog signals representing battery voltage, battery temperature, and battery current, and converts those signals to digital signals. The processor receives those digital signals from the converter and uses those digital signals to perform a series of calculations.
