摘要： In accordance with aspects of the present invention, a method of providing a fuel gauge is provided. The method includes measuring a battery current through and a battery voltage across a battery; determining an equivalent resistance from the current and the voltage using a multiplier K; determining an open circuit voltage based, in part, on the equivalent resistance; determining a state-of-charge based on the open circuit voltage; and adjusting the multiplier K based on the current and the state-of-charge.

摘要： Embodiments described herein provides a battery charging circuit that boosts an input current and feeds the boosted input current to a battery for fast charging. Specifically, the battery charging circuit includes a low dropout regulator (LDO) for providing a voltage, a switch mode charger, coupled between the LDO and a battery, and a capacitor divider, coupled between the LDO and the battery, in parallel to the switch mode charger, for dividing the voltage outputted from the LDO by a factor.
