GM Adopts Tesla NACS like Ford!

[Sillybibbles]

I think my main issues will remain:
1. cost per KWH,
2. Location

I live in a multi-family without home charging, so for me this isn't just for occasional road trips. Cost matters, and right now only the L2 ChargePoint slow chargers managed by my county are affordable ($.16/KWH).

I would probably go back to 100% ICE if it wasn't for home charging. I'm not sure how you manage that. When people ask me what I like about EVs my answer is always; home charging (never having to go to a gas station and much less expensive) and the instant power.

I think Electrify America will be fine, E.A. have good locations near me - better than Tesla-and are affordable-ish with the membership. E.A. have worked well for me.

But for the life of me I can't figure out why anyone would use the horrible by-minute, EVGo chargers. I cannot fathom who would still choose to use EVGo if they have any option - especially when their chargers are 50KWH slow, and per-minute charging is insane and ridiculous for the last 20% - even over $1/KWH. I suspect EVGo will be bought out within a few years.

Per minute is not an EVGo thing. It's how many different companies operate in various states. In California, per minute charging is illegal and EVGo uses per kW here. They have native plug n charge, which is very rare, so that makes them even more lucrative. As for slowness, do your research before stopping because many, many different companies have lower amps (with higher voltage) than the MME will charge at, netting slow speeds on the MME.

Interesting. I'm in VA, so who knows why they do per-min. Maybe they will see most consumers hate it and eventually change over- there are EVGo chargers near me I drive past to get to 150 KHW electrify America Chargers, so if EVGo would make the change I would switch to them immediately.

Also a good insight on the voltage versus amps. But I have not yet seen any voltage that can't manage the full 150 khw that the MME can do. Maybe in future 800v chargers, but that's still very rare.

It's not the voltage that's the problem. Most of those older units have low amperage which leads to the low charging speed. You need both. For example, a charge unit that maxes at 150a and the MME maxing at 400v would be 60kW delivered before losses.

This is a chart of current EV charging plug AC and DC "CCS-like" standards and their regions, across the world (a bit more than two):

Well there goes the neighborhood. Watch all the Bolts line up.

Good news is the bolts are dead.. they are being replaced by other crappy gm cars.

Wonder what will happen with the billions of govt money being poured in chargers that were going to be CCS

Dongles for a decade...

Dongles for a decade...

And lots of non-rated dongles for sale on Amazon.

Unless GM comes out with next gen Bolt hot hatches. Not sure on likelihood, but thst would be kind of cool if they can reinvent the Bolt with better charging and performance.

Why not? Tesla already has an adapter out that does CCS to NACS and it can do 250kW, why would an adapter that goes NACS to CCS have some harder limitation? The only reason to worry about the adapter and rate limitation is if they have to implement cable as well due to the short length of the SuperCharger cables. If it's a cable also adapter then the rate may be limited since the cooling won't extend to the cable.

How far are the cable runs inside the MME? I don't think those are liquid cooled.

Re the necessity of an adapter making our cars obsolete, I'm not saying it's an invalid concern... but our cars' internal constraints on charging speed are gonna make our cars obsolete much faster than the necessity of an adapter. So I don't think it's anything to get worked up about.

At least in the short run, an adapter gives us more versatility.

there may be eventual pushback from the public since their prices are 10-15 cents higher than others, making it more expensive than an equivalent tank of gas.

Here in CA Tesla has/had been charging ~$0.42/Kw and even if they charge $0.50 (20% more) the gasoline equivalent here in CA ($5/gal) will still be far more expensive.

Obsolete is such a strong word - don't underestimate the size of the used car market for people who just want something to commute in - students who just need something to get to and from school, seniors who just want local driving, people who need something reliable to get to/from work and don't have the money to go on roadtrips even if they wanted too, people who are happy to save several grand on a car purchase if it means just putting up with occasional slower charging, etc.
