AN AUTHENTICATION SYSTEM FOR A PLUG-IN ELECTRIC DRIVE VEHICLE

摘要

An energy auditing system for a plug-in electric drive vehicle. The system comprises a first device electrically connectable to a first power apparatus and an electrical power connector. The electrical power connector establishes an electrical power path between the first device and a remote device which is electrically connectable to a second power apparatus. The first device comprises control means, a first sensor, a control switch and a receiver. The control means controls operation of the first device. The first sensor selectively measures an amount of electrical energy delivered to or received from the first power apparatus and generates a first signal representative of the measured amount. The control switch is configurable to electrically connect and disconnect the first device to the first power apparatus. The receiver is configured to receive an energy audit signal transmitted from a remote device, the energy audit signal representing an amount of energy transferred over the electrical power path in a specified time interval. The first device's control means is operable to compare the first signal with the received energy audit signal in the same specified time interval and to electrically disconnect the first device from the first power apparatus when a power loss between the respective devices is detected.
