It's hard to make direct analogies because unlike gas vehicles, EVs "refuel" at home. You wake up every day with a full tank of gas. Fast DC chargers are mostly for road trips. And while it's a good thing that everyone has adopted the same charging standard, branding is just as important. Gas at gas stations is fungible. EV chargers are most certainly not. Right now Tesla's charging network is the only option that is…

People in denser neighborhoods, appartments buildings or who rent their property will be looking to top off while running errands or at work.

If I'm in such situation, I never buy BEV unless charger is installed at my parking. Without home parking charging, it's pure downgrade from gas experience. It will be eventually installed if govt really care about BEV.

In europe the connections are a lot lower amperage, around here for example 35 ampere per phase. But having 3 phases is pretty normal and the standard in any new house, which means 3 phases can let you charge at 22kW with a few Ampere left, while with 1 phase you can only charge at 7 KW. That does make it useful to charge it in a few hours in the afternoon, instead of having to wiat the night.

In which European country is triphasic power for houses becoming normal?

apartment blocks always do

I expect a degree of intelligence to be important in the adapter. Specifically, unless the adapter is rated for the highest possible current and voltage that the physical form factor can support (1kV, 600A? Is there even a pre-ordained limit? Tesla reports that they’ve tested NACS up to quite impressive voltages and currents.), then the adapter needs to tell the car and/or charger to limit voltage and current. Otherw…

Isn't that negotiation already part of the CCS protocol? Otherwise 400v cars would be fried when they end up getting 800v from an L3 charger, or a Bolt would end up getting 300kW that it can't actually use

Yes, but if there’s a dumb adapter between the car and the charger, how do the car and charger know it’s there and know its current and voltage limits (which may be less than the car’s)?

>Every single EV can plug into every charger. Nit picking, but there's a bunch of Nissan Chademo still around. Like my Leaf. I'm a bit perplexed that Nissan is still selling new Chademo cars here, since it's on the way out. I very rarely need DC charging though, and there's still lots of Chademo locations if I do. That aside, the Leaf is a wonderful car.

DalasEVRepair on YouTube is testing a Chinese CCS to CHAdeMO adapter. If that ever becomes a reliable product, then NACS to CHAdeMO would be an incremental change.

Convert 50kW by random cheap adapter, it looks like a one of the most dangerous thing.

I am the founder of Starlight Charging[1]. We are working on crazy-low-cost L2 chargers for multifamily apartments. Plug-and-charge is a sine-qua-non for us. One still major unsolved problem is the lack of agreement on a standard for payment/powerline communication from the EVSE to the vehicle. OCPP 2.0.1 and ISO 15118 is supposed to bring "Plug and Charge" capabilities -- this, in theory, would allow drivers to simp…

Some feedback: I only barely realized "plug-and-charge" means something specific. [1] Generally speaking, I wouldn't expect people to know what you mean by the phrase. The problem is that people think they know because it sounds so obvious. The phrase comes across more like: "obviously, yeah, I plug it in and it charges". That understanding leaves vague the number of steps required between "plug" and "charge". [1] e.…

Aah wait so it's Plug-And-Supply-Currency rather than Plug-And-Supply-Current?

But it also takes away Tesla's biggest advantage, no? The charging network was a big reason to buy a tesla and now that's gone. So perhaps they will actually end up losing more revenue than gaining.

Tesla was always going to lose the EV battle in the long run - if not to VW and co, then to BYD and co. This lets them pivot to something where they have a huge moat.

Will Tesla slowly reduce market share as the market grows? Yes, But I don't see a situation where Tesla doesn't have quite a while of sales growth and best in class EVs.

That may be your perspective, however I have family members who owned a plugin hybrid, had no at home charging capabilities, and found the experience superior. I suspect this is a use case that will become more prevelant at the regulatory incentives begin ramping up.

I don't realistically see us being able to rollout sidewalk chargers on the scale needed to provide home charging at the sidewalk for people without driveways or garages.

If they are the last domino, they also have the worst negotiation position. Whatever number Tesla says will be their cost.

why would Tesla be involved? NACS is an open standard

Will every car that implements a standard be able to use the Tesla Superchargers at full speed? Or would the charger decide if it trusts the car first?

The design of the car is only loosely related to the skateboard that contains the battery and the drivetrain.

Considering 90% of modern consumer automobiles use a monocoque frame the design means everything to the chassis

All cars made by the Volkswagen group are based on like 20 platforms. For example the Audi A3 and the Skoda Yeti are the same platform. They look quite different.
