ADDITION OF SIGNALS INTO ISO 15118-20: PARAMETER: V2XAvailableDischargeEnergy / EVSessionTotalDischargeEnergyAvailable

A computer-implemented method comprising:

• receiving, by a device comprising at least one processor, a communication comprising a discharge request, wherein the device is located on an electric vehicle (EV) wherein the discharge request is received from an electric vehicle supply equipment (EVSE) coupled to the EV, and wherein the discharge request is for discharge of electrical energy from a battery located onboard the EV;
• determining, by the device, an amount of electrical energy available for discharge at the battery, wherein the electrical energy is available for discharge to an electrical grid operated by a third party;
• and
• transmitting, by the device, to the EVSE, the determined amount of electrical energy available for discharge.

A computer program product stored on a non-transitory computer-readable medium and comprising machine-executable instructions, wherein, in response to being executed, the machine-executable instructions cause a system located on an electric vehicle (EV) to perform operations, comprising:

• receiving a communication from an electric vehicle supply equipment (EVSE) coupled to the EV, wherein the communication comprises a discharge request, wherein the discharge request is for discharge of electrical energy from a battery located onboard the EV;
• determining an amount of electrical energy available at the battery, wherein the electrical energy is available for discharge to an electrical grid operated by a third party;
• and
• transmitting, to the EVSE, the determined amount of electrical energy available for discharge.
