Abstract
A charging system for a battery of an electronic device is described. The charging system comprises an adapter configured to derive a transfer current at a transfer voltage from a power source. Furthermore, the charging system comprises a battery charger configured to charge a battery of the electronic device with a battery current at a battery voltage using the transfer current at the transfer voltage. In addition, the charging system comprises power transmission means configured to transmit the transfer current at the transfer voltage to the battery charger. In addition, the charging system comprises communication means configured to transmit feedback information which is indicative of the battery voltage and/or battery current from the battery charger to the adapter. The adapter is configured to set the transfer voltage and/or transfer current in dependence of the feedback information.
