Hi, I would like to connect the power supply shown in the following pictures to my department's E-van (Ford E-Transit). My boss told me to just go buy a dryer cord and connect them, but when I look online none of the cords for sale have either of the configurations that we have in our wall sockets. The power seems to be 208 volt. I would appreciate any guidance in how to connect the van to this power supply. I also attach photos of the van's receiving port and two cords that fit into the wall receptacles. I have no idea what that one with the four blades in a circle is about.

Many thanks in advance.
