1. A multiple function current-sharing charging system, comprising:
- a power source interface configured to receive energy from a power source;
a power converter connected to the power source and configured to regulate the energy received from the power source and to output charging current;
a plurality of power supply interfaces configured for connection to respective rechargeable power supplies; and
a charging controller connected to the power converter to receive the charging current and to the plurality of power supply interfaces, and configured to detect connection of a first rechargeable power supply to a first one of the plurality of power supply interfaces, to determine whether a second rechargeable power supply is connected to a second of the plurality of power supply interfaces, and to provide a first charging current to one of the first and second rechargeable power supplies and a second charging current to the other of the first and second rechargeable power supplies where a second rechargeable power supply is connected to a second of the plurality of power supply interfaces.
