The invention relates to a protocol for discharging DC power from a propulsion battery pack to an off-board charging station. A method for coordinating a discharge session in which direct current power is offloaded from a power source, such as an electric vehicle (EV), to a bi-directional off-vehicle charging station includes exchanging charging data between the EV and the charging station in response to the power source being connected to the charging station via a set of charging lines. This occurs on the low voltage communication line, where the charging data includes power and current limits of the EV and the charging station. In response to the limit indicating a negative limit representing a request for a discharge session, the method includes transmitting the EV power and current limit to the charging station to confirm the request. In response to acknowledging the request by an exchange of a unique identifier indicating support for the discharge session, the discharge session is initiated.

    本发明涉及从推进电池组向车外充电站的放电直流功率的协议。一种用于协调放电会话的方法,在该放电会话中,直流功率从例如电动车辆(EV)的功率源卸载到双向车外充电站,所述方法包括响应于功率源经由充电线组连接到充电站而在EV和充电站之间交换充电数据。这发生在低压通信线路上,其中充电数据包括EV和充电站的功率和电流限值。响应于所述限值指示负限值,负限值表示对放电会话的请求,所述方法包括将EV功率和电流限值传输到充电站以确认该请求。响应于通过指示对放电会话的支持的唯一标识符的交换来确认请求,启动放电会话。
