Chevrolet Bolt EV & EUV 2022 Official Thread

Just curious. What's 'broke' on your Prius? The very typical Head Gasket?

There is news that the Bolt may not be canceled after all.
There may be a pause in production while they change the battery pack layout.
Nobody knows for sure.
You could pay for a test drive in a Bolt. Do you know about Turo?

After renting an M3 for 4 days and using the SC network.... the $10k difference is for a reason. It was an amazing experience!
You can actually take road trips so much easier.
But ,,, you can take road trips in a Bolt. It just takes longer. And it may be cheaper to buy the electrons.
How often do you travel on long trips?

 

Yeah, I’m getting an intermittent misfire / rumbling symptom.
Mechanic took it for a drive and couldn’t feel it, but he probably didn’t drive it long enough.
No codes, and he didn’t want to throw parts at it.
So I’ll probably pay him to look at the egr and plugs, maybe coils, but there’s only 30k on the engine.
I recently read about turo, I may do that.
This will be an around town car, we have the hycam for traveling.
I could never convince Mrs B of ev traveling, she gets nervous when the gas tank goes below half

 

GM recently announced they were going to continue the Bolt with a new battery. If they do these fixes, I would take a closer look:

• Tesla plug - integrated with the SuperCharger network
• +100 kW charge rate - the existing 50 kW does NOT work
• Different battery - announced to be an Ultium
  • Go with 4680 cell battery

This would be a reasonable refreshed model incorporating the best of today's technology. I don't expect serious competition to the Tesla EVs. GM's Bolt still has 'body in white' legacy to carry everything around. But as a former GE manager once said to the software lead, "90% isn't good enough, it is perfect! SHIP IT!"

The GE manager needed to get the software into the hands of the integration and test team (I&T) and early operations staff. That way they could identify the problems, assign priorities, and get the software team focused on what was really important. As the VAX/VMS operating system programmer, I consulted with I&T about issues the software developers would never bring to me.

i drove an hour to the dealer, only to have them tell me they don't do refundable deposits. i got up and started to walk, and the sales weasel said hold on, i'll go talk to my manager.
came back and said they'd make a special exception for me.
i said, 'you think i'm going to do business with a company that lies?' and walked out.
tesla drive saturday, and i'm looking at leaf's.

 

So it's full of stale gas? That sure could explain an intermittent misfire...

 

i wish it were that simple. the gas is only a few weeks old from the local mobil station.

i've since realized the the stumbling is only on light accelleration, which is how i drive, but probably not how the mech drove it.
in another egr thread, a claim is made that this indicates a clogged egr valve. however, in the same thread, they claim disconnecting the egr input power will show it is clogged if the behavior goes away. something about the knock sensor, but this was also disputed by a knowledgable member who said a disconnected egr would be the same as a clogged egr.

 

Do you have an OBD scanner setup?

Often the error codes can map where to look for problem(s). They are really easy to operate and the codes can often be detailed by clever folks in PriusChat.

--The Tesla plug is coming, but it's only the connector that changes.
It doesn't mean you have to buy your electrons from a Tesla Supercharger, if there's a different DCFC station across the street and they charge less for the same flavor of electrons.
And, as you know, we're throwing lots of tax dollars at making the charging networks bigger.
And adaptors will be common place for years to come for legacy CCS EV's.
Imagine a 'Gas Buddy' app for EV's?

--50kW DCFC DOES work with the Bolt. That's how I drove my Bolt home from LA to KC, and that was back in '20. Cheap lease returns were showing up everywhere!!
It works, just slower than more modern EV's.

--I don't think the Ultium is going cylindrical. For one thing, that's a lot of stainless steel cans. Packaging is not ideal.

 

the mech has tech stream, no codes, no trouble lights

 

So this was today with the BMW:

Had to get home to access a better editor:

• $0.28/kWh = $2.27 / 8.0 kWh :: nominally cheaper than SuperCharger
• ~29 mi = 3.7 mi/kWh * 8.0 kWh :: @70 mph range added in just under 12 minutes
• ~145 mi / hr charge rate = 29 mi * ( 60 min/hr / 12 min)
• ~87 mi = ~75% charge :: longest distance between 50 kWh, CCS-1, fast DC chargers, 0%-75%

Knowing how charging worked, I stopped just before the next minute charge. So I got about 58 seconds of free .764 kWh. Learning how to stop a charging session for maximum good is an art.

So for my BMW i3-REx running in just EV mode, I would need CCS-1 chargers about no more than ~90 miles along the route. Using PlugShare, there are a lot 'being built' but many of them are at dealers who often have them locked up after hours, ICE by dealer inventory, or 'for our customers.'

used?

 

@bisco, if you're not fixated on a new one and didn't mind a little trip, Todd has several clean Bolts right now at Tampa Hybrids. He's been stocking up on them. They sell fast. I stopped by on Friday and he had one that just came off the truck and was already sold before they could even prep it.

As for road trips, the Bolts works better than a lot of people claim as long as you're not in the "I gotta get there asap" crowd. On our way back from Michigan last fall, we stayed right with an F-150 Lightning all day long. He was there at all four of our charging stops. He was getting more kW, but also needing a lot more kWh.

As for a Leaf, I wouldn't touch one. The 1st generations was really bad for battery life. They improved it, but there is still no real thermal control for the battery even on the newest ones. And for a road trip, forget it. Heat will throttle the charging speed plus you'll be looking for Chademo chargers. They are available and common, but not as plentiful as CCS.

PS: I'd gladly pick you up at the airport if you need a ride and will arrive when I'm available.

 

Is there a message here? A story with a beginning, middle and end?

I can tell you got 0.7640 kWh for free! Is that it?
You actually paid $0.28/kWh. Is that it?
How is it in Athens this morning? That could be a story!!

 

I tend to report the facts and data and leave stories for others. Regardless, once I got home I added more calculated metrics based on measured and observed values.

There was one other EV getting a charge at the four lane station. I used the dual CCS-1, CHAdeMO unit with 150 kW rated output. My BMW charge rate ranged from 42 kW @50% SOC to 45 kW @72%. I wanted to see if it would reach 50 kW with more modest temperatures 81-83 F. I've already benchmarked 106 mi EV range in no-wind, 71 F, 100% SOC. The BMW charge rate drops rapidly approaching 80% SOC and higher.

So back of the envelope:

• ~1 hr :: 75 miles @70 mph and 3.7 mi/kWh
• ~36 min (0.6 hr) :: charging for the next 75 miles, about 0% to 75%
• ~47 mph = 75 mi/1.6 hr :: expected cross country speed on Standard day and 75 mi between available and working CCS-1 chargers

So I have two EVs, 2017 BMW i3-REx and 2019 Tesla Model 3 Std Rng Plus:

• BMW better Urban vehicle - short wheel base, reasonably efficient at urban speeds, highly maneuverable. It is usable for cross country driving on the Range Extender engine that bypasses the worst aspects, unreliability and slow 42-45 kW charging, of CCS-1 charging.
• Tesla better Cross Country vehicle - longer wheel base smooths roads, more efficient at higher speeds, reliable and fast, 178 kW peak rate at SuperChargers, Autopilot/FSD handles driving monotony.

that's what i'm struggling with. an ew premiere to me would net at 25k. there are very few used around here, and usually around 30k, so you can't even get the used 4k credit.
but ordering a new one is difficult with the shady dealers in this area.

 

Sitting in a Sonic or Trax should give you an idea of what a Bolt is like.

The Bolt was done well for what it is. If GM does a gen3, it will be on the newer EV platform. The current one getting a new battery would be part of a typical refresh in the design cycle. GM did upgrade the Volt and Spark EV battery as part of refreshes.

Dealers are traditional car companies worse enemies.

Low miles and light driving can be as bad high miles and heavy acceleration. You could have deposit build up in the engine. I'd put a bottle of fuel system cleaner into a tank, and drive it 'spiritedly' before pulling things apart.

 

no new bolts to be had, but maybe that's not a bad thing:
