US Patent 10453282 EV charging connector unlock via biometric input

An electric vehicle (EV) charging system includes a receptacle on the EV and a controller. The controller may be configured to, responsive to a removal request and a discrepancy between a stored biometric record and first biometric data received from a first biometric sensor, compare the stored biometric record and second biometric data received from a second biometric sensor that is different from the first biometric sensor, and responsive to the comparison matching, generate an unlock request.
