Characterizing a Battery for use with a Battery Fuel Gauge
Jul 1, 2011
Battery packs require characterization to maximize battery fuel gauge chip performance in various applications. To obtain the best performance from a battery fuel-gauge chip, the battery pack must be characterized so that the cell's behavior in an application can be fully understood. To do this, characterization designers should charge the pack at room temperature and then discharge the pack at heavy, medium, and light loads at room temperature, and medium loads at cold and hot temperatures....
