Abstract:
1. A method for controlling charging of a battery, said method comprising: providing a target charge current; measuring battery current; determining if the target charge current is less than the measured battery current; enabling a current integrator if the target charge current is less than the measured battery current; integrating a charge current value over time if the current integrator is enabled to provide an integrated charge current value; providing a target charge voltage; measuring battery voltage; determining if the target charge voltage is less than the measured battery voltage; enabling a voltage integrator if the target charge voltage is less than the measured battery voltage; integrating a charge voltage value over time if the voltage integrator is enabled; and adding the integrated charge current value and the integrated charge voltage value to provide a charge current value that is used to charge the battery.
