A charging device for use with an electric vehicle having a power storage device includes a current control device configured to selectively enable current to be received from an electrical distribution device and supplied to the power storage device. The charging device also includes a processor coupled to the current control device. The processor is configured to determine a first amount of current available to be at least one of received from the electrical distribution device and supplied by the charging device, and control the current control device to enable a second amount of current to be at least one of received from the electrical distribution device and supplied to the power storage device if the second amount of current does not exceed the first amount of current determined to be available.
