Method and system for current regulation at a receiver of an electric vehicle configured for wireless power transfer

A method of protecting against overvoltage in a vehicle assembly of an electric vehicle, said vehicle assembly being in communication with a ground assembly as a part of a wireless power transfer system for electric vehicles, said method comprising:

• repeatedly transmitting a power request signal to the ground assembly via a communication unit in the vehicle assembly;
• detecting an overvoltage event across an output of the vehicle assembly;
• and
• diverting current off the output of the vehicle assembly, into a by-pass circuitry, upon detection of the overvoltage event,
• wherein upon receiving an indication from the protection circuitry of the overvoltage event, stopping transmitting the power request signal to the ground assembly via the communication unit.

A non-transitory computer readable medium for protecting against overvoltage in a vehicle assembly of an electric vehicle, said vehicle assembly being in communication with a ground assembly as a part of a wireless power transfer system for electric vehicles, the computer readable medium comprising a set of instructions that, when executed, cause at least one computer processor to:

• repeatedly instruct a transmission of a power request signal to the ground assembly via a communication unit in the vehicle assembly;
• receive a detection of an overvoltage event across an output of the vehicle assembly;
• instruct a diversion of current off the output of the vehicle assembly, into a by-pass circuitry, upon detection of the overvoltage event;
• and
• instruct stopping of the transmission of the power request signal to the ground assembly via the communication unit, upon receiving an indication from the protection circuitry of the overvoltage event.
