Charging device and methods for controlling a charging device
First Claim
1. A charging device for use with an electric vehicle including a power storage device, said charging device comprising:
- a power conduit configured to electrically couple the power storage device to said charging device;
a first protection device configured to electrically isolate said charging device from the power storage device if a current flowing through said power conduit exceeds a current limit; and
a controller configured to control the current flowing through said power conduit if a temperature within said charging device exceeds a predetermined threshold, wherein said controller is further configured to transmit, when the temperature exceeds the predetermined threshold, a signal from said charging device to the electric vehicle that causes the electric vehicle to adjust a current drawn from said charging device by the power storage device, wherein said charging device is external to and separate from the electric vehicle.

Abstract
A charging device for use with an electric vehicle including a power storage device. The charging device includes a power conduit configured to electrically couple the power storage device to the charging device. The charging device includes a first protection device configured to electrically isolate the charging device from the power storage device if a current flowing through the power conduit exceeds a current limit. The charging device also includes a controller configured to control the current flowing through the power conduit if the current flowing through the power conduit causes an integration threshold to be exceeded, wherein the integration threshold is representative of a predetermined amount of current that is enabled to flow through the power conduit over a predetermined period of time.

4. A method of controlling a charging device, said method comprising:
-
supplying current to a power storage device of an electric vehicle using the charging device; measuring a temperature within the charging device; and adjusting the current supplied to the power storage device based on the measured temperature by transmitting, when the measured temperature exceeds a predetermined threshold, a signal from the charging device to the electric vehicle that causes the electric vehicle to adjust a current drawn from the charging device by the power storage device, wherein the charging device is external to and separate from the electric vehicle. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A system for use in charging a power storage device of an electric vehicle using current received from an electric power source, said system comprising:
a charging device comprising; a power conduit configured to receive current from the electric power source and to provide the current to the power storage device; a first protection device configured to electrically isolate said charging device from the power storage device if a current flowing through said power conduit exceeds a current limit; and a controller configured to control the current flowing through said power conduit based on a measured temperature within said charging device by transmitting, when the measured temperature exceeds a predetermined threshold, a first signal from said charging device to the electric vehicle that causes the electric vehicle to adjust a current drawn from said charging device by the power storage device, wherein said charging device is external to and separate from the electric vehicle. - View Dependent Claims (15, 16, 17, 18, 19, 20)
