Abstract
A charging system of the present invention is connectable to a power grid having a monitoring device. The monitoring device monitors the power delivered to a plurality of loads and determines a power factor and a power factor correction value associated with the loads. The power factor correction value indicates the difference between the power factor and unity. The charging system includes an electrical device, a charger in communication with the electrical device, a charging controller, a power factor correction circuit, a communication device, and a controller. The communication device of the charger receives a data signal from the monitoring device indicative of the power factor correction value associated with the plurality of loads. The power factor correction circuit is configured to communicate an input current to and from the power grid, which adjusts the power factor of the associated loads to about unity.
