1. A device, comprising:
- a charger for conveying an output signal to a battery;
a monitoring system including coulomb-counting analog-to-digital converter for measuring a current received by the battery; and
a control device configured to receive a sampled battery current value from the monitoring system and calibrate a signal conveyed to the charger in response to a comparison of the sampled battery current value to a target current value during constant-current charging.

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.
