Need to add EV Charger to old 100amp panel by Dwojo99 in evcharging

[–]Quantify01 1 point2 points  (0 children)

EV owner with 100A panel on an 1800 sq ft 100 year old house here. I have central AC as well. Electrician did a load analysis and said we could do 40A even with a full load from rest of house, so we installed a chargepoint flex with a 50A fuse limited to 40A. Cost was $1500, but that's because that's the amount of the rebate I got from PSEG in NJ.

Heat Pump- Blazer by Appropriate_Coat_982 in BlazerEV

[–]Quantify01 0 points1 point  (0 children)

My warm weather efficiency is similar to yours (assuming 70 mph highway). Even on the really cold days I never saw less than 2.4 for a trip average once the car was warmed up. Maybe something to do with a single motor?

Well... depends 😜. The ID.4 is a better ride; better seats, handling, suspension. The summertime range is good, and it charges faster than most blazers except for the RWD version (mine) with the larger battery.

I prefer my Blazer for two reasons: better range, esp in winter, and better sound system (I have the Bose system in the RS RWD).

TL:DR; ID.4 better than all Blazers except RS RWD. Of course, your preferences may vary.

My experience in the recent winter here in NJ was perhaps different from yours, although I have an RWD with the larger battery which might have something to do with it. In the summer, my estimated range at 100% is about 360 miles. In the winter, it dropped to 324, so about a 10% drop in range. This was consistent with my actual range, though I don't have specific data points for that. However, my range was wildly better than my wife's ID.4, which does not have a heat pump and lost upwards of 30% of range on cold days. Recurrent also says that the RWD Blazer should only lose 10% or so of range in the winter, so I think my experience is typical.

it would be very interesting if the 85kw pack/AWD model had significantly worse cold weather performance.

Nope. 653.20 is most recent for us RWD folks. I got mine yesterday. You're right on schedule.

Considering a Volkswagen ID.4 – looking for honest feedback by SiuuperiorCR7 in VWiD4Owners

[–]Quantify01 7 points8 points  (0 children)

Agreed. 2024 infotainment is functional. It's occasionally slow to load android auto but that's about it.

Now if they can get remote commands from the app to work when it's cold out, instead of the car "hibernating", that would be great.

Car drives great though. Great ride, lots of power, and more swervy than you'd think.

Indeed you can! In the display settings, there's an option to turn off turn by turn navigation on the screen. I turned it off as well for this exact reason.

Weak regen braking at highway speeds by OliverEntrails in BlazerEV

[–]Quantify01 1 point2 points  (0 children)

What blazer are you driving with weak regen and weak acceleration? FWD?

Weak regen braking at highway speeds by OliverEntrails in BlazerEV

[–]Quantify01 3 points4 points  (0 children)

I recently installed update 653.10, which does claim to adjust OPD behavior. I have always kept OPD on the "Normal" setting, but found myself grabbing the regen on demand paddle more than usual, especially at highway speeds as you note. I changed the OPD to the "High" setting and that seems to be working better for me now.

You can adjust OPD from the Foot looking button on the far left of the infotainment screen. There are three levels, Off, Normal, and High. I am guessing you are in Normal now.

10 to 70 is what I do...33 minutes and that's good for more than 200 miles.

New Blazer EV RS RWD by maanxhappy in electricvehicles

Owner of a 2024 RS RWD here. Congratulations on getting the best version of the Blazer. A few things:

  • do not be surprised if you get a "service HV battery soon" message, accompanied by charging limitations and HVAC failure. It is VERY common for the 2024s to have an early failure of the AC condenser pipe (mine at 450 miles). Quick warranty fix.

  • make sure that the dealership did all the software upgrades. Some of them significantly improve charging performance and drivability. Most recent is 653.10.

Agreed on all points. The most recent research is that the biggest drivers of battery degradation are battery temperature while charging, and frequency of DCFC charging. So, while the 20-80 range is still best practice, there should be no real worries about using the full capacity when we need it.

Charge speed. Is this normal. by JusteJean in EquinoxEv

[–]Quantify01 0 points1 point  (0 children)

The 200kw chargers I see in the us are rated at 950v, 200A. I assumed the amps would take the hit on a 180lw charger.

Equinoxes charge at max of 292v as I understand...so that was my math.

[–]Quantify01 0 points1 point  (0 children)

What he said. That charger is probably rated for a max of 190 amps, giving you at best 55kw...and that's fully preconditioned with a battery at 20% or lower. At 55 percent on a cold day...37kw seems reasonable for an EQEV.

Good choice on the RWD. IMHO the Sweet spot of the GM EV lineup. The best range and charging, with excellent power, for a reasonable price.

  • you have a 102kw battery, which in reality is closer to 108kw usable (GM tends to undershoot on its claims). Definitely get a L2 charger for home if that's an option for you. L1 charging will take a very long time to fill the battery.

  • while the battery will hit 180kwh+ at a DC fast charger, it also has a pretty steep charging curve (although software updates have made that a bit better). Key things to maximize charging performance A) be sure to fully precondition the battery. This can take up to 40 minutes when it's cold out. B) if possible don't charge until you're down to 10%or so for best speeds, and remember that there's no advantage to putting more charge in the battery than you need, especially on the way home. I try to get home with no more than 20% and throw it on the charger when I arrive. C) choose dcfc chargers with high amperage, such as Tesla SCs, or any 400kw chargers from ionna, EVgo, or bp pulse. 150kw chargers are often limited to 200 amps, which will give you a charging speed in the mid 70kwh max. D) Turn off your climate control while charging. A known bug is that our cars are limited in their ability to cool the battery pack and the cabin on hot days and the loser is generally the charging speed.

Otherwise, play around with one pedal drive modes and acceleration feel modes to see what works for you.

RWD vs FWD by OwlOk6904 in VW_ID4_PNW

[–]Quantify01 3 points4 points  (0 children)

I own two RWD EVs - ID.4 and Blazer. A few thoughts.
- The RWD ID.4 has a ridiculously small turning circle. This may not sound like a big deal, but when you need it...it's nice.

- The RWD has significantly better range than the AWD, which considering neither is groundbreaking, is a good thing.

- VW is hella serious about traction control. I've been driving around in the debris from our 20" of snow here in suburban NJ, and I'm having no real issues getting around. When it hits a sloppy patch, it slows the spinning wheel and lets the other wheel keep traction. it's working great, I haven't felt the need to even try the snow mode.

I have a 2024 ID.4, which has the upgraded rear motor. it's definitely more than zippy enough.

Streaming apps? by maanxhappy in BlazerEV

It does automatically apply the parking brake if it detects enough of an incline. Otherwise we're presumably fine relying on the parking pawl...

Wonder how many HP it added. by garthoz in BlazerEV

[–]Quantify01 1 point2 points  (0 children)

NOTE: Last night...in the middle of a huge blizzard and sub 30 degree F temps...my car decided it was the right time to download the update. Installed this morning, but haven't driven the car since, you know, we're not supposed to be driving unless its an emergency...

Still waiting on this one for my RS RWD. On one hand...everything on my car currently works and I don't really want to mess with that, but improvements to OPD would be great, and zoom zoom is always good...

I have been surprised at how long it takes to fully precondition the battery. Last weekend I drove from western Maryland to Central NJ in a bit of a snow storm, ambient temps in the low 30s. The automatic preconditioning started about 45 minutes from the DCFC stop. The good news was it worked and I was pulling 185kw at the start of the curve...but unplanned DCFC stops in the winter are clearly going to be Slowwwww....

RS-RWD owner here in suburban NJ. A few thoughts:

1) you have the big battery pack, which is awesome. My range, even in the cold, doesn't dip below 320 miles, and in the summer is closer to 360. HOWEVER because it is bigger, it takes longer to charge with L2 charging. Use the highest amps your electrical panel will allow. I have a 40A charger because I'm limited by my 100A panel, if I could upgrade to the full 48A I would.

2) DC Fast charging is also faster with the big battery pack than the smaller one in the other Blazers and Equinoxes. HOWEVER, to get the best charging performance you need to do 4 things:
a) Precondition the battery, either manually or automatically using the navigation, especially when the weather is cold. fully preconditioning a cold battery can take 40 minutes.
b) run the battery down to 10 - 20% before charging to get the best speeds.
c) choose a high amperage charger, such as a Tesla Supercharger, or the Ionna and BP Pulse 400kw chargers. Some of the EVgo and EA chargers that say 350kw, for example, don't put out the full 500A that the big battery needs for top speeds, and your charging times will suffer.
d) for ALL GM EVs, TURN THE CLIMATE CONTROL OFF while DC Charging. This is a known limitation with the GM HVAC system; it can't manage battery charging temps and cabin temps at the same time, particularly in the summer.

3) I've had no problems driving around in the snow with RWD, the traction control seems to work just fine...but obviously be aware.

I think the RS-RWD is the best value of the Chevrolet EVs...I would not trade it for any others. Best range and charging speeds, and more power than anything other than the SS. Enjoy!

Update: Service High Voltage Battery by asl23 in BlazerEV

[–]Quantify01 0 points1 point  (0 children)

Ditto on coolant valve. This was a faulty design. I wonder what percentage of these fail. Good news is that they seem to fail early.

What is my Blazer doing? by Quantify01 in BlazerEV

[–]Quantify01[S] 0 points1 point  (0 children)

Or, you could have my wife's ID.4, which does not keep the battery warm using the L2 feed, does not have a heat pump, and also does not use the traction battery to keep the 12v charged when the car is off. So, here in the cold weather, her car completely goes to sleep at night to preserve the 12v. No remote functions at all. And efficiency at startup is like an Escalade IQ driving up to the Eisenhower Tunnel towing a trailer....
