The described technology is generally directed towards implementation of an electric vehicle (EV) as an energy generator for a vehicle to grid (V2G) power discharge operation. Energy available at a battery onboard the EV can be discharged to an electrical grid, e.g., via an electric vehicle supply equipment (EVSE)/wallbox. The EV can forward a EVSessionTotalDischargeEnergyAvailable parameter identifying an amount of electrical energy available for discharge from a battery onboard the EV. The EVSE can configure a power discharge profile for the V2G operation based on the value of the EVSessionTotalDischargeEnergyAvailable parameter. Accordingly, the power discharge profile can be configured so as to not exceed the value of the EVSessionTotalDischargeEnergyAvailable parameter. Communication between the EV and the EVSE can be in accordance with ISO 15118-2, ISO 15118-20, etc.
