Today I noticed PlugShare was showing a local Chevy dealer had a CCS charger installed. Went to check it out and was surprised to see they had mounted a free 25KW CCS charger on the outside of their building. It was branded with "Chevrolet" but some googling showed me that it's made by a Chinese company called Delta. A search for Delta EV Wallbox will pull up pics of the generic branded version.

Has anyone else seen these at their dealer? I had read that all Bolt certified dealers would have to get CCS chargers, but assumed they would not be publicly available.

Would that be H&L Chevrolet in Darian?

Indeed. Two free CCS chargers in Darien, and no other working ones in the rest of the state! I usually use the other free one, but some fool had their Bolt charging unattended for close to two hours. Next time I'm just unplugging it if it's at 80%.

All Bolt EV certified dealers are required to acquire a CCS DC fast charger.

To my knowledge the GM recommended unit that does come Chevrolet branded is the Bosch EL-52240. Are you saying that Bosch is re-branding this from someone else? Or is this a different unit that you saw?

Not sure if it's a multiple listing but Bosch does own the UL listing for this unit as well.

I have never used charging away from home. What is the accepted "protocol" for sharing a station? Is it murky or has it more or less been established? What can one expect?

It is very similar to George Carlin's "Idiot / Maniac" routine.
If someone else is charging when you want to use it, they are an idiot. If they want to use it while YOU are charging, they are a maniac.

I saw photos of the Delta wall box and the Bosch wall box and they look the same to me.

So true. As long as a person is actively charging the vehicle and not breaking any posted rules, calling them idiot is very maniac

Bosch EL-52240C - Power DC Plus 25 kW is only $5k new. I was expecting it to be more expensive. Needs 165A input power. Each Chevy dealer should have one of those... I mean functional one, not like Keys Chevy...

Yeah, both units appear to be the same. I'm guessing Delta supplies them to Bosch who supplies them to GM. Apparently Delta also sells them directly.

Murky would be the right word.

For Level-2 AC slow charging I would say its first-come, first-served. No excuse to unplug someone unless you can tell their car is fully charged.

I have a different view on CCS DC fast-charging. If someone needs to fast charge they should be with their vehicle since the charge shouldn't take that long. And, they should not be charging past 80% if someone else is waiting. I have no qualms about unplugging someone who has left the car and is at >80% charge.

The box is only a fraction of the total cost, though. You're going to need to trench and repave to lay cable out to the box, you're going to need curbing, bollards and paint to protect the box from getting hit by vehicles, signage, $10k+ in electrical work alone and more if the trenching has to go very far... Getting a publically accessible CCS up and running is a mid-5-figures commitment. Having a portable one that plugs into the welder outlet that's enough to test CCS charging on a car being serviced is much less expensive.

A depleted Bolt EV at a 25KW DCFC can take about 72 minutes to reach 80% charge. Clearly, I want to go use the facilities and eat a meal!

I guess I should turn back on the charger alarm.

This makes perfect sense, but I have never heard of this point of etiquette before. Only the one about unplugging once the car is full. I hope the unplugged driver is not provoked by that. Also, it may be impossible to tell the state of charge for some vehicles.

Running inside to grab something quick and use the facilities is fine. But, leaving the car for >30 minutes seems inconsiderate to me. I don't know about others, but the alarm wouldn't stop me from unplugging a Bolt that's showing over 80% charge. The general public is well conditioned to ignore car alarms.


A lot of the issue is that 25KW chargers aren't fast by any means, and definitely not appropriate to "fast charge" a Bolt or any EV with a large battery.

Now reread my post SLOWLY and CAREFULLY: I said I leave my Bolt EV to charge to 80% and you want to chastise me about charging in excess of 80%.

I monitor my Bolt EV's charging progress with the MyChevy app and I return in the high 70s.

So, your apology is accepted!

Your last sentence is nothing short of idiotic!

I don't know if I'd call it proper etiquette. It's just my opinion. The absent driver would likely be annoyed at being unplugged, but there isn't much they can do and it's their fault for being inconsiderate. It's a public resource and no one has exclusive rights.


As for state of charge, a lot of the chargers show it, and often the car's display shows it.

First, chill out. Your post was two sentences and made a general statement about how long a Bolt takes to charge to 80% at 25KW and how you like to use the facilities while it's charging. If you monitor your charge level and come back before your car exceeds 80% then you never have to worry about me unplugging you. Not that we live anywhere near each other.


No idea why I would apologize to you, and I don't.


My last sentence is absolutely correct. 25KW takes forever to charge a vehicle with a large battery. It's far too slow for that purpose unless someone dumps their car at the charger for hours which is an issue for other who want to use the finite resource.
