Claim 4:
5. The electric vehicle charger of claim 1, wherein communicating with the electric vehicle over the charging connection includes identifying the payment method associated with the electric vehicle by:
receiving, from the electric vehicle over the charging connection, a first indication including a public key of an asymmetric cryptographic key pair associated with the payment method;
generating a random number;
sending, to the electric vehicle over the charging connection, a second indication including the random number;
receiving, from the electric vehicle over the charging connection, a third indication including a payload and a digital signature for the payload, wherein the payload includes the random number and payment data, and wherein the digital signature is signed using a private key of the asymmetric cryptographic key pair associated with the payment method;
validating a signature of the payload using the public key; and
communicating with a payment network to authorize the payment method for payment for the electric power supplied to the electric vehicle by communicating, based on the payment data, with the payment network using the communication device to authorize the payment method,
and wherein the controller is further adapted to initiate supply of the second level of electric power subsequent to authorizing the payment method for payment for the electric power.
