I don't think people can hear this loud enough. I own an EV with CCS, I'm glad the rest of the industry looks to be going NACS. CCS is in fact objectively terrible. CCS could only seem decent when it was following on something as truly atrocious as Chademo.

Can you explain your reasoning? I have an EV with CCS and have never had a problem with it, so I don't know what is "objectively terrible" about it.

Heavy. Huge. Expensive. Complex. Prone to failure.

Basically like any design-by-committee output.

Sandy Munro has a conflict of interest he doesn't always highlight when reporting on Tesla-related issues.

Please tell.

He is really into good engineering which has made him a huge fan of Tesla, especially since they took some of his recommendations and incorporated them into their manufacturing process.

It is fair to say he is biased, but at the same time I don't see why his assessment of NACS vs CSS is wrong.

Its a plug, its bigger than NACS but apart from that its hard to notice the difference as a consumer

It's better engineered and designed. It's that simple. Yes, the differences aren't mind-blowing, but who cares. As long as they properly open it up and standardize it as they are saying they will, then this is a perfectly good outcome. Most EVs and fast chargers in the US have Tesla/NACS ports anyway, so this is the easier lift to standardize.

It's not black and white: CCS supports 800V charging, NACS does not (yet). Higher voltage = lower current and lighter cables and less strain on the connectors.

Superchargers wete also lagging on liquid-cooled cables, which will be included in v4.

If it's possible for NACS to support 800V charging then that is not really a very meaningful advantage of CCS, is it? I think Tesla themselves will eventually switch to 800v at some point.

V3 Superchargers have liquid cooled cables, that's why they are thinner than V2 cables. V4 has even crazier liquid cooling, where the conductors are directly immersed in the coolant.

From what I can see, telsa use CCS2 but with a different plug.

In the EU/UK they have the CCS2 plugs on them, and are compatible with any CCS2 capable car.

(source: me, I used one last week for a non tesla car)

Sure it can support higher voltage in a new revision, but that means currently deployed chargers have an inferior design in that aspect, doesn't it?

Sure, but I don't know whether that would be a hardware revision or just a protocol thing how complicated it would be. Could be a software update for all I know. Is it the case that all currently deployed CCS chargers support 800v charging? If not, is it possible for an 800v architecture vehicle to charge at a 400v CCS charger?

Plus, if the concern is the port then I don't necessarily mind that fast charging companies will have to deploy new hardware, as long as the cars don't need to get retrofitted all the time or use adapters.

> it can support higher voltage in a new revision, but that means currently deployed chargers have an inferior design in that aspect

It's tough to bring currently deployed chargers to CCS's defence, given most deployed chargers are Tesla's.

That sounds like goal-shifting, considering I was arguing against gp's rather absolute claim on NACS having superior design and engineering:

>> It's better engineered and designed. It's that simple

CCS currently supports 800V. NACS is going to support 800V. The number of extant chargers with 800V capability is, to a reasonable approximation, the same for CCS and NACS. So NACS being able to support 800V rhetorically balances CCS being able to roll out 800V chargers (or any, period), at least in my mind.

Put another way, one solution is deployed and capable of upgrading. The other is also capable of upgrading, maybe comes upgraded already, but hasn't been deployed. The first strikes me as better engineered. (The latter may have superior design, but I have trouble buying that argument given NACS can be upgraded.)

This is what Tesla fans say, but the actual reasons they give are weak.

The advantages of CCS: It supports 800V today, it supports V2L/V2H/V2G today.

The advantages of NACS: It's smaller, which nobody cares about except Tesla fans.

Did you watch Sandy Munro's analysis on it? He's one of the leading minds in the auto industry.

what are the bullet-point issues?

V2x is a matter of protocol, not the connector.

The advantage of NACS is that it has a working network of chargers, and plugs in effortlessly.
