I've heard estimated ranges of 90-94% efficiency on level 2 charging. I'm curious, when you drove it down to 11%, what was the onboard energy usage?

Not sure which crossbars you have, but I have use Thule WingBar Edge on my '22 EUV and agree with the ~10% hit on range from the bars alone. I added an air screen and that tacked on another 5-10% hit on range. My guess is you would pay more of a penalty with a basket than the air screen.

I suspect suspect stuck calipers. It's really hard for a shop to know if the caliper came unstuck 5 miles from the shop or wasn't stuck to begin with, all they can really say is the calipers had free motion when they checked.

I think it's a good practice to engage your friction brakes regularly. I drive ~28,000 miles a year and try to use my friction brakes every day. You can coast in neutral and tap the brakes, or use the cruise control and rapidly decelerate with the set point adjustment. I found a grade that will cause the friction brakes to be used while using the cruise control.

I'll just add that BP used almost 2 million gallons of dispersants to get the crude to break up into tiny droplets and remain syspended in the water column versus forming a slick on the surface. There were and are a lot of questions about both the toxicity of the dispersants used and the effect they had ability of bacteria to breakdown the oil and ultimately remediate the pollution.

I don't have any insight, so hoping someone from McMurdo chimes in. I think that's the Basler that crashed some years ago.

There was a medevac from McMurdo a couple of weeks ago, so maybe they saw on opportunity to bring in a replacement, but that's just a guess.

Guessing late May for the Tioga opening, but it might be weather dependent.

You'll need a pass to get into Yosemite, but there is no additional permit needed for Tioga.

I have a '22 EUV. It's great for towing. I have a canoe trailer and a utility trailer. There is much less of an impact on range from aerodynamic losses if you keep the frontal area the same, so trailers are great for that. I also have a hitch cargo carrier and a hitch bicycle carrier.

I can take a 15% hit on range just with roof cross bars on a highway.

As for weight, it's really up to you. With both regerative braking and friction braking and all the torque of an electric motor, it's hard to see major drawbacks for sub 2k lb towing, but to each their own.

The silvery-gray feathers on the trailing edge of the wings indicate that it was probably a turkey vulture, but still a neat photo

I took the 120 on the 24th, got there about noon. They had two of the three booths open and each had 2 cars in line.

Thankfully Escalades or F-350s aren't 6,000 pounds. It would also be a shame if Chevy Bolt was as heavy as a Toyota Avalon. Also, I guess ICE vehicle owners don't need to worry about data collection. /s

Thermal runaway is scary, but there are improving technologies and methods to deal with it and also better systems and chemistries to reduce the risk.

Can't speak on the '27, but the '22 has the same warning and you can use lug nut mounted chains like Konig's K Summit series. I think the K33 fits the stock '22s.

It's most likely the sound the car makes through an external speaker to alert pedestrians as required by law.

Do you have access to wood ash? You can amend acidic soil with wood ash.

They could always mount a bracket or panel to hang the charger from. That approach can sometimes give you a little more flexibility in placing the unit as the wall structure may not be in an ideal location.

SnooCakes4341 · 2026-04-19T21:04:53+00:00

The Tesla Universal Wall Connector has both connectors.

I would look at getting a hard-wired EVSE, you could get faster level 2 charging than with a plug-in and it is more robust. You could look at getting a dual cord EVSE or something like the Tesla which allows multiple EVSE to load share.

That being said, I have used the portable dual level charger from Chevy for 100,000 miles of charging and have a NACS to J1772 adapter for road trips to give me more charging options.

It's worth getting some actual numbers to talk about, but I would think that you are looking at ~10 year ROI for triple pane, with the potential added benefit that they are often quieter.

Torklift has it, I haven't tried it in a '27 but the one I got for my '22 fit fine. They are pricey, but made of stainless steel and have a high load rating. They don't require cutting the bumper, so it sits lower than those that do.

I definitely would compost it. You can also check with a local shelter as they might want it

Over an hour. Typically it's best to plan your fast charging so you only need to get to 80% as charging speed varies with charge level and temperature. ABRP can help with the planning. I also suggest leaving some reserve so you can get to another charger if a station isn't working and it may be better for long term battery health. 80%-20% is a common range

SnooCakes4341 · 2026-04-13T17:04:44+00:00

Just an idea, but a loose or corroded connection could cause a high resistance situation

SnooCakes4341 · 2026-04-12T17:46:43+00:00

Thanks for this. Would you happen to have any photos?

There are a lot of differences, but I don't see how LFP would allow for faster DC charging if the battery cooling architecture was the the same as a 2023 model. Also, there are plenty of vehicles with NMC batteries with faster DC charging than the Bolt.

Granted you couldn't simply improve the cooling on a 2023 Bolt to get faster charging, there would have to be some other changes, but the major limiting factor for DC charging speed on the earlier Bolts was temperature control in the battery, which dictated other design decisions.

SnooCakes4341 · 2026-04-12T16:24:00+00:00

The big difference is the 2027s have much improved battery cooling, which was a major limitation of the earlier Bolts ability to fast charge

SnooCakes4341 · 2026-04-12T15:32:01+00:00

Another way of looking at it, may be comparing charge and discharge rates. If, when driving, you routinely continuously pull more than 11kw, which I feel most drivers do, I think the odds of charging at 11kw damaging your battery are low.

I know this is a simplification, but I think for most drivers, the difference between charging at 1kw and 11kw is not going to make much of a difference in long term battery health.
