Title: BATTERY CHARGING SYSTEM WITH A REGULATION LOOP
Abstract:
A charging system (100, 200) for a battery (140) of an electronic device is described. The charging system (100, 200) comprises an adapter (110) configured to derive a transfer current at a transfer voltage (121) from a power source. Furthermore, the charging system (100, 200) comprises a battery charger (130) configured to charge a battery (140) of the electronic device with a battery current at a battery voltage (141) using the transfer current at the transfer voltage (121). In addition, the charging system (100, 200) comprises power transmission means configured to transmit the transfer current at the transfer voltage (121) to the battery charger (130). In addition, the charging system (100, 200) comprises communication means configured to transmit feedback information which is indicative of the battery voltage (141) and/or battery current from the battery charger (130) to the adapter (110). The adapter (110) is configured to set the transfer voltage (121) and/or transfer current in dependence of the feedback information.
