Abstract: Exemplary embodiments are directed to systems, devices, methods, and computer-readable media for calibrating a charging current. A device may include a charger for conveying an output voltage to a chargeable device. The device may also include a monitoring system including an analog-to-digital converter for measuring a current received by the chargeable device. Further, the device may include a control device configured to receive a charging current value from the monitoring system and convey a signal to the charger in response to a comparison of the charging current value to a target current value.

Abstract: A method, apparatus, and non-transitory computer readable medium are provided for high current battery charging using IR dropout compensation. The method first measures a battery current value and then multiplies that battery current value by an effective resistance of the battery to produce an effective dropout voltage value. The effective battery voltage value is then compared with a desired battery top off voltage value. The switch mode battery charger output setpoint is adjusted based on the setpoint voltage. Battery current and terminal current are then compared. Charging is terminated if the battery current is less than the terminal current. If the battery current is greater than the terminal current the battery current value is measured again and the charging process continues until the condition is met.
