Abstract
Techniques are described for quick charging of batteries. For example, a battery charging system can include a battery charger integrated circuit (IC) and a fuel gauge IC coupled between a battery and a central processor to execute a stored multi-phase battery charging protocol. Executing the protocol can include charging the battery in a constant current regulation phase by applying a constant charge current until a charge voltage (e.g., measured by the battery charger IC) reaches a defined regulation voltage that is higher than the nominal voltage of the battery plus the voltage drop across series components of the battery. Protection of the battery during such charging includes monitoring a present relative state of charge (RSOC) of the battery (e.g., by the fuel gauge IC) to detect when the present RSOC reaches a defined regulation RSOC level that may be substantially 100 percent of the charge capacity of the battery.
