Title: FAST CHARGING APPARATUS AND METHOD
Abstract:
A method comprises setting a first termination voltage, a first charging current and a first termination current in a first charging step, wherein the first termination current is a fraction of the first charging current, passing a current from a power source to a battery through a charger, wherein the charger operates in a first constant current mode and the current is equal to the first charging current, monitoring a voltage across two terminals of the battery and configuring the charger to operate in a first constant voltage mode when the voltage across the two terminals of the battery is equal to the first termination voltage and monitoring the current in the first constant voltage mode and configuring the charger to operate in a second charging step when the current is equal to the first termination current.
