Abstract

A system for charging a plurality of power storage devices includes a first charging device and at least one other charging device coupled to the first charging device to form a network. The first charging device includes a processor programmed to determine whether said first charging device possesses a network token, and if so, to determine a first charging parameter and a first priority associated with said first charging device, a second charging parameter and a second priority associated with said second charging device, and to determine a second amount of current to be at least one of received from the electrical supply or supplied to the first power storage device, based on the determined first and second charging parameters and first and second priority.
