Abstract
A method for coordinating a discharge session in which direct current power is offloaded from a power supply, e.g., of an electric vehicle (EV), to a bidirectional offboard charging station includes, in response to connection of the power supply to the charging station via a charging cord set, exchanging charging data between the EV and charging station. This occurs over a low-voltage communication line, with charging data including power and current limits of the EV and charging station. In response to the limits being indicative of negative limits, with the negative limits representing a request for the discharge session, the method includes transmitting the EV power and current limits to the charging station to confirm the request. The discharge session is initiated in response to confirming the request through an exchange of a unique identifier indicating support for the discharge session.
