Abstract
In one embodiment, a fuel gauge system is described that comprises two or more battery chargers on different integrated circuits (ICs) coupled in parallel to a battery for charging the battery. Each battery charger IC generates a current signal indicative of current generated by said each battery charger IC into the same battery. A fuel gauge is responsible for accurately reporting the battery state of charge, based on a combination of voltage, current, and temperature information.
