ELECTRIC VEHICLE WIRELESS CHARGING WITH MONITORING OF DURATION OF CHARGING OPERATIONAL MODE
First Claim
1. A method of transferring wireless power to an electric vehicle, the method comprising:
- initiating a charging cycle of a wireless power transfer system, the charging cycle comprising a plurality of operational states comprising;
at least one initialization state during which a wireless power link sufficient for charging is established between the wireless power transfer system and the electric vehicle; and
at least one charging state during which wireless power transfer from the wireless power transfer system to the electric vehicle is performed;
generating a first timestamp indicating a start time of the wireless power transfer in response to entering the at least one charging state; and
generating a second timestamp indicating an end time of the wireless power transfer.

Abstract
Systems, methods, and apparatus are disclosed for electric vehicle wireless charging. In one aspect, a method of transferring wireless power to an electric vehicle is provided, including initiating a charging cycle comprising at least one initialization state during which a wireless power link sufficient for charging is established between the wireless power transfer system and the electric vehicle and at least one charging state during which wireless power transfer from the wireless power transfer system to the electric vehicle is performed. The method further includes generating a first timestamp indicating a start time of the wireless power transfer in response to entering the at least one charging state and generating a second timestamp indicating an end time of the wireless power transfer.
