Classification: CPC H  G | IPC G  H

Claim 0:
1. A battery-charging system configured to charge a battery of a device to a nominal voltage, the battery-charging system comprising:
a battery-charging circuit coupled to the battery;
a load-detection circuit coupled to the device, the load-detection circuit being configured to detect a load powered from the device, the load-detection circuit being located electrically downstream from the battery;
memory storing controller-executable instructions; and
a controller configured to execute the instructions, which cause the controller to detect the load above a first threshold load using the load-detection circuit,
control the battery-charging circuit to charge the battery to a high voltage in response to detecting the load above the first threshold load, wherein the high voltage is above the nominal voltage,
detect a load below the first threshold load using the load-detection circuit, and
control the battery-charging circuit to charge the battery to the nominal voltage in response to detecting a load below the first threshold load.
