TS : Where does the idea of bi-directional charging come from ?
GI : Bi-directional charging was born after a natural disaster : Great East coast Fukushima , 2011 . After the earthquake and the subsequent tsunami , Japan suffered severe blackouts . To accommodate their energy needs they used EVs during recovery efforts to support rescue and medical personnel . Electricity was required to assist in the rescue efforts and CHAdeMO ' s functionality allowed them to use power from the EVs . That was the first implementation of CHAdeMO ' s V2X functionality .
After this natural disaster Japan developed a bi-directional protocol to use EV batteries as distributed energy resources to formalise the process for future emergencies . Until recently , CHAdeMO was the only protocol that enabled V2X ( Vehicle-to-Everything ) technology , among the international DC charging standards .
