Does any charging standard support daisy chaining?

Ubbquittious

So that if you arrive at a charger that's in use you plug your car into the car that's being charged instead to get some bit of power and when that car finishes or slows down you automatically get all of it?



Even if it''s not implemented are there any that would at least support it in theory?

Just a wild guess here but I imagine the charger is giving all the car can take,I'm also thinking both cats would have to talk to the charger at the same time and have a duplicate set of lines within the first cable ,that or the two cars have a chat to each other and work it out themselves.
I'd be going with it would be easier/ cheaper to add another charge point than try to reverse engineer that mess.

An then when the owner of the middle car in the chain comes back, he’s going to have to extricate himself and hopefully plug the next car back in. That in itself may complicate things where payment for charging sessions are involved.

That's a silly idea.

If the limit is on number of cabinets, it'd make more sense to position each fast charger at centre of a grid of four spaces, with four cables, and balance the 150kW or whatever between the four cars.

Then you'd get interesting boy-girl-boy-girl formations of Teslas and rapidgating Leafs. You could even have an app suggest which space to take based on the available power, and a possible model for discounting time-based charges for slower-charging cars.

Queuing for a 150kW fast charger when only 50kW is being drawn is just stupid, given the relative cheapness of cables.

You'd need another port on the car too (if fast charging), huge expense

Tesla Superchargers already do some this 'pairing' with A & B chargers are same stalls:

Most already know, two stalls at Superchargers share one charger. For example 2A and 2B are connected to charger #2 and share it's power.

The way they switch is actually interesting. Superchargers are made from (I believe) 12 smaller chargers that each max out at 12 kW. 3 are always grouped together as they use the three phases from the commercial grid power. When both stalls (that share a charger) are used, the power output can only be switched in groups of 3. So when you arrive and the other car is using all the power, you will get the minimum which is 36 kW. Once the other car tapers down enough you will get another group of three which adds up to 72 kW. The next step is 108 kW.

Not sure how this works now with V2 & V3 Superchargers however.
