How about a receptacle in the front of the car and a supported 'Bus Bar' type connector that slides into it horizontally ? I think another issue with the huge power draws on future chargers is how well the connections contact or are held together . As I have mentioned , some type of clamping action could be done either by the connector or maybe by the vehicle receptacle .

What article was that? That seems very unlikely to be true.

They claim 97% efficiency has been achieved.

Honda announced this week that they're working on fluoride ion battery tech that can boost LiOn battery capacity (per volume) by 10x. Older versions of that type of battery required heating them up to around 300-degrees, not something viable in a car. They're also non-flammable, so safer in that view. The key is developing low temperature operation and a viable electrode.

Now, take the original i3's battery, bump that up 10x in the same volume and that would be a game changer. Or, use less of that available volume for other things (what, I'm not sure) and your options would grow rapidly. Now, charging one up would almost certainly require CCS on a trip, but you could still recharge it more often so the timing wouldn't be unreasonable from your home EVSE, I suppose.

Think about some of the existing or soon to be released plug-in hybrids right now with limited range...bump that up 10x, or take away the penalty often seen by decreasing luggage capacity and again, a game changer.

Seems that Toyota and Panasonic have formally signed an agreement to produce LiOn batteries. Their goal is to also continue to develop SS versions. Planning factories with enough capacity for over 5 million vehicles per year. They plan to share some of the output with some, including Subaru and Honda. Others may get involved as well.
