Classification: CPC H  G | IPC G  H

Claim 4:
5. The system of claim 4, wherein the device controller is further configured to control the battery charger circuit to implement a charging current profile comprising:
a precharge trickle current flow during a first part of the charging current profile at a level below the threshold and at or above the other threshold;
a constant current flow during a second part of the charging current profile at a level at or above the other threshold;
a constant voltage during a third part of the charging current profile during which current flow declines from a level of the constant current flow to a minimum level, due to increasing charge stored on the battery; and
continued minimum level current flow in a fourth part of the charging current profile in which a battery has reached a fully charged state.
