We should have a North American Standard charging system and require every EV sold here (or imported here) be compatible with it. Lots of things have a universal standard - electrical plug ins, sheets of plywood, flashlight batteries, light bulbs, etc. Can you imagine the public standing for gas stations that only worked with some vehicles.
We have one: CCS: Common Charging Standard. Is the ANSI standard created by All The Automakers, with the exception of Tesla.
Then they expected farmers whose only "crop" is government handouts to build and run the CCS fast charging systems. That worked exactly as well as any reasonable person would expect. It worked so bad you'd think it was a Disney reboot of Snow White.
Then one day Ford had enough and joined Tesla's Supercharging network, created a NACS adapter for their vehicles and started putting NACS on new EVs as soon as they could. GM fell in line quickly after.
So, we do have a North American Charging Standard, it is the Tesla Supercharger. The same plug is used on Tesla L2 connectors (they are fancy extension cords, not chargers) such as the Mobile Connector and Wall Connector where they speak the same J1772 protocol as the J1772 connector.
Way back when, when the SAE/ANSI committee was "designing" their charging system and connector Tesla tried to give them the current NACS connector but the committee didn't believe DC charging was going to be necessary and didn't like having AC and DC on the same pins. No matter the pins are not powered until communication is established with the vehicle, they thought they would have to pay for more expensive DC rated contactors if there was any possibility of DC being present. AC contactors and switches cost less than DC.
So the committee rejected the elegant Tesla NACS connector in favor of the butt-ugly J1772,
And then when they were forced to add DC charging support they made yet another committee decision and grafted DC pins to the J1772 connector resulting in CCS.
Then there was the mess of entities whose primary interest was to collect government funds, "built" the CCS charging networks. Hired one contractor to build hardware. Another to write software for that hardware to communicated with the EV. Hired another contractor to write the billing software. Other contractors to build the charging sites. Other contractors to maintain the charging sites. And then couldn't understand why the work of all these contractors was not meshing together as one smooth operation?
Then there is Tesla who built the Supercharger network without government funding. Didn't qualify as a one-make solution. Spent their own money. Designed their own hardware. Wrote their own software. They did train contractors to build the Supercharger sites. The result is night and day versus the CCS debacle.
