The present solution may perform a handshake process to establish a bi-directional session using communications, which may be implemented on EVs and chargers from various manufacturers. The present solution relates to a charger that may perform handshake process communication between the charger and an electric vehicle to establish a session for bi-directional power transfer between the charger and the electric vehicle via a power cable. The charger may transmit a data structure to the electric vehicle during a handshake process, the data structure including a field for a minimum current, the value of the field being less than zero. After transmitting the data structure including the value of the minimum current, the charger may be configured for a session of bidirectional power transfer between the charger and the electric vehicle via the power cable. 本解决方案可执行握手过程以利用通信来建立双向会话，该通信可在来自各种制造商的EV和充电器上实现。本解决方案涉及一种充电器，该充电器可在充电器和电动车辆之间执行握手过程通信，以建立用于经由电力电缆在充电器和电动车辆之间进行双向功率传输的会话。该充电器可在握手过程中将数据结构传输到电动车辆，该数据结构包括用于最小电流的字
