...which will not be applicable to the passenger vehicle market.When we have a need for multi megawatt charging,
Those are going to be two entirely separate markets, so no, there won't be any need to make the big megawatt power connections for semi trucks fit with cars.At that point, people will just toss out the old stuff and start over, and there will be a set of adapters to get the old cars to work with the new standards.
Television transmission is one market, not two separate ones, like this.The same thing happened with NTSC (made to be backwards compatible with the old black and white TV) to ATSC (different enough that they just started over and gave anyone who wanted to keep using an old TV a converter box).
It's not. We are already supporting about 300 kW with the existing connectors for passenger vehicles. Charging times are already down to about 15 minutes. It's not going to need ridiculous megawatt level charging. That 300 kW kind of level is fully sufficient from the connectors there. It's two other things in other areas that make the connector hardware not the issue:the old hardware is already too limiting.
1. Battery tapering. The connectors supplying 300 or 350 kW are fine, but vehicles can't accept it for very long. So that's where it's limited, and there really is room for more improvement--to receive what the connector can provide.
2. Cumbersome cable thickness. This is why there will need to be a distinction between large bulky cumbersome connectors versus what is smaller, lighter, more convenient, and easier to handle for the consumer market. Many things in many industries are like this. The big high power industrial versions of things are allowed to be big and bulky because they need it, while the public doesn't stand for that in consumer products. Cables as thick as your leg can't become a thing for regular car charging standards.
