Toroidion 1MW electric supercar

Battery that you can carry indoors... that's a good one. Maybe you can take the individual cells out, meaning you only have to do +-50 trips to get the whole thing inside and charging. Practicality spelled with a capital P right there.

Charging small modules separately and then hooking them together (with potentially different levels of charge) would be a recipe for disaster!

Looks like a kit car, especially the interior.

Sarcasm aside, in theory you could concieve a powerstrip that you can connect the cells to (if you construct them right), and it only starts running/charging when all are present, and it has all the BMS functions you'd want.
However, a battery to move such a vehicle over a respectable distance would weigh at least 500kg, unless we're looking at the new, now-and-forever champion of Wh/kg ratio. So bringing the whole thing inside is a silly notion either way, especially if the alternative is to plug in a cable. Or, have your butler plug in the cable for you, given the car costs in the seven figures.

I have no idea how serious they were about taking the battery indoors for charging, but I think we really do need to remember this type of car definitely does not have the same mission as a Tesla. Everyday practicality is not the driver and we should adjust our thinking, I think, to that mission.

So, the thinking about a battery you can take inside for charging changes a little if you think of - say - having two or three of the batteries (hey, money is no object at this price range anyway) and charging them beforehand for a trackday or a race. If, say, two-three people can realistically carry/swap the battery, that might offer some practicality at the track, to be able to swap the battery by hand. Putting the whole car into a charger for some hours is not the answer.

Obviously taking the battery indoors for charging is not meant for your average daily commute, but then, this car hardly is either.

p.s. As for a kit-car interior, a concept from a small startup, it probably is off-the-shelf components put together. Could be anything from near final to nothing like final at all.
