GM will be rolling out with Bolt EV, primarily that would be any GM dealership. I really do not know about the count, but it is interesting place to start. The way forward would be to rope in utilities like NRG(which already has lot of charging stations) to provide the backbone for the system. As days go by it looks like the major car companies are in agreement with their plug standards. The other aspect is free charging is not promised by Tesla on Model 3. So cannot take into consideration for Bolt EV infrastructure.

Right. No existing infrastructure, just cobbled together dealership charging stations. No autopilot in the Bolt. No OTA software updates (in the US, at least), as it violates the franchise agreement with dealerships. No high-voltage DC charging such that a Supercharger can offer (just the designed-by-committee CHAdeMO junk).

That's why Tesla is 5 years ahead.

Tesla started putting out super chargers in 2011, even in 2013 it was anemic and nothing outside of their traditional bastions, from mid 2013 is when they ramped things up and have currently put out there. So 2 years. On Auto-Pilot front Audi, Volvo and Mercedes(these guys have a truck on auto-pilot) are out there and they are not lagging in pure technical terms, as I said deployment wise they have to do the ground work. It does not matter CHAdeMO is supercharger a 20-30 minute fast charging is NOT ideal(too much wait and too much screwing the battery), and people should be looking for better solutions.

Fine. Let's say any legacy automaker can deploy an entire network in 2-3 years. When does that start? Will it be starting soon?

Having used both chademo and supercharging extensively they are totally not the same.

One is 1/3rd the speed of the other in real-world usage.

Chademo charges a Leaf (or similar class car) to 80% in around the same time as SuperCharger does for a Tesla Model S, doesn't it?

If you want 100 miles of range, sure.

I can tell you charging chademo on a Model S is much slower.

Of course, but Chademo isn't designed for a Model S, it's designed for more affordable cars with smaller capacity batteries. The market requirement for both a Leaf and Model S DC fast-charge is the same: charge to roughly 80% capacity in 30 minutes.

As I said elsewhere, the Chademo connector can support higher currents when there is a need. When there are Leafs (and Souls? I think think those are the only two in the US on Chademo) with 200mi range batteries, I'm sure we'll see the existing chargers upgraded to the higher current capability.

You sure about that? When the model s chademo adapter came out Teslas were breaking chademo stations left & right because they weren't engineered to handle 25min @ 45kw.

I'm not aware of and chademos above 60kw today while Tesla has a while infrastructure deployed right now.

Nissan has tried this with the Leaf and hit hasn't worked well. Dealerships aren't incentivized to provide charging and I don't see that changing.

Also there is no currently deployed charging standard that comes closer to SuperCharger. Chademo is 60kW spec but usually 40 or 50 depending on how downrated the charger has been. I've never seen less than 118kW on a Supercharger and had multiple Chademo's that have throttled down to 35kW in some cases.

It's going to take years to build out that infrastructure while Telsa continues to deploy SuperChargers and Destination Charging.

Chademo deliberately selected 50kW as being optimal given the cars using the charger and the infrastructure available; the connector is designed for up to 200A (up from 125A at present) which would yield 100kW.[0] My understanding is that the CCS connector is being deployed at 200A now. I don't know what you're definition of "close to" is, but I would consider 100kW and 118kW to be close.

Business model for a dealership involves buying a lot of cheap land on the outskirts to provide space for a giant parking lot, a service station, room for all the trucks to load and unload, etc. Space around them is usually bought by other dealers, so it can be branded as an auto mall. In most cities you usually have to go out of your usual route to visit a dealership.

Tesla superchargers require less real estate footprint and are next to freeways and frequently next to Starbucks and some casual restaurants.
