Bolt!

[mzziaz]

Yeah, that battery is both weird (small) and pricey. Had to replace ours earlier this year. It never recouperated properly after a pretty deep discharge last winter.

[CaminoRacer]

Dealership said it's $350, so I'll go with Advance Auto's for $250

how does a discharged 12v prevent the car from starting? there's no starter/engine to turn over

Is there an alternator or how does the 12v get charged?

Everything but the motor still runs on a 12-volt system.
Ask me why they can't make an integrated step-down voltage regulator that can jump the 12v system off the high voltage batteries, and I will tell you I don't have a clue.

On boats, it's considered better to have a lead battery in addition to a lithium bank. Lead acids can absorb electronics-frying dump loads on BMS shutoff while DC charging. And if you're going to flatten _a_ battery (which destroys lead acid and lithium alike), lead acids are the ones you want to kill. Dunno how much of that applies to EVs though. Certainly weight is less of an issue on boats than it is on cars.

Electric cars could be better and lighter if ancillary systems ran on higher voltage, but 12vdc systems are so prolific across so many vehicular industries.

I'm stoned and I just made that up, but it sounds good.

The 12v battery flips the big relay or whatever to activate the big battery pack system.

The remotes also operate on the 12v system. We couldn't get into the car with the remote, had to use the backup physical key.

That checks out. You need something to manage the BMS.

When I have BMS, I use Metamucil.

Its actually quite a bit more difficult changing voltages in a DC system. It could be done through the main motor's inverters, but it would be really inefficient.

I'm a way from home at the moment and I left the Infiniti, with an own-band four-year-old Autozone battery, on a Ctek battery-minder thingy. My understanding is that heat is usually what brings batteries to a premature end.

[CaminoRacer]

I got Cross Climate 2s installed today. The old tires still had decent tread on them but not enough to inspire any confidence in light snow or slush.
Now that the car is better prepared, I'm sure it won't snow again all winter.

[FoMoJo]

I had a set installed on my car a couple of months ago; mainly because I like the tread pattern.

[Laconian]

I love our CrossClimate 1's. Great tires. They perform well in all conditions.

I test drove a Bolt EUV in the same outing as the EV6 and Ioniq5. It's a really great car. Very fun to drive. It's so easy to spin the front wheels. GM's redesign of the front seats was a great success. I had no issues with the seat width or bolstering.

[CaminoRacer]

At some point I might try to find newer seats to swap in.

[MrH]

I need to test drive a Bolt EUV.  If it was AWD and better looking it'd be an even bigger success

  I have the 2s on the Infiniti, put them on just over a year ago. It never effing stops raining here (plus the autumn leaf goop, plus the wintery stuff.) They transformed the car - recommended. These will replace the CX5's OEMs when the time comes.

Nah, it'd be much more expensive. Whatever the Bolt EUV is, it nails it. Great car that drives and feels much nicer than the pricetag suggests.

I have the CC2s on the Alfa... Work really well year round, minor lack of lateral grip in the summer

How do the tyres affect range?

[CaminoRacer]

How do the tyres affect range?

I didn't expect much reduction since the car had Hankooks on it, not the OEM Michelins. But the range does seem to have taken a small hit. I'm waiting until the tires are broken in a little bit more before I fully judge the difference. I've heard some Bolt owners say the range of any new, non-OEM tire is bad at first and then improves after a few hundred/thousand miles.

[CaminoRacer]

AWD is also much less efficient. There's more of a range hit from AWD than decent tires. I don't see much need for AWD. I've driven to work in my Miata in the snow all week without much issue.

EV6 LR batt AWD: 274 miles
EV6 LR batt RWD: 310 miles

That's a 12% range reduction. Not the end of the world. But yeah, people have been absolutely fine with FWD for many decades.

[CaminoRacer]

These wheels looks awesome, I should get some.

[Eye of the Tiger]

Hou should get ultra light forged 13" wheels, or the smallest that fit over the brakes

I looked at getting 16" wheels before I bought the CrossClimate 2s in December. Would probably have better ride quality

[MrH]

Those do look really good.  I saw that earlier on Reddit.  I like the gold + red combo.

How did the CrossClimates impact range and efficiency? That's probably what I'll go with once these stock tires wear out in a couple years.

I love fat tires. They make all the sense on these crappy public roads. I have convinced more than one person to give up their rubber band tires.
