I have a 2023 AWD Bzx4. The fastest charge I’ve ever gotten was 74kW, but on average only get 37kW. I brought it into the dealership today, and they showed me a setting on the dash that you can get to for Charging speed. Mine was already set to Max. It’s pretty disappointing how slowly this thing charges. Makes it ineffective to drive outside of town. Thank you for charging with Electrify America.

Welcome to the forum, Crookster! Have you noticed if the charging speeds improve under certain conditions, like temperature or battery state of charge? Do you have any specific road trip plans in mind now that you've got the bZ4X?
 
#222 · (Edited)
I've had my bZ since April of 2024. 80% charge had gotten me 250 miles range constantly. The few times I've charge to 100% has gotten me 290-to-300-mile range. I'm waiting for the change in weather to see how the charging will be affected.

I got my 24 bZ AWD Limited in July, since then I’ve only used DC charging 3 times and haven’t seen more than 90-100 kW and 80% of battery between 30 to 40min. That was until yesterday (we currently have temperatures of 20 degrees Fahrenheit) and I was driving the car for around 20 minutes, also tried to yoyo drive it. When I plugged at the usual DC Fast station it only did 13 kW with less than 50% of charge, I didn’t even check the time to 80% because I knew if was going to be excessively slow even after “warming” the battery.

We all know that performance will be slower in the cold, but I hope the 13kw that you saw was just an aberration!

39F ambient temp car was driven for 30min prior. Max speed 55kw after starting at 40. When I turn on cabin heat it throttles to 40s again. Started at 13% charge. Disappointing

Same here. I also note the consumption rate has dropped. My average consumption during the summer months peaked at 3.8, it's now down to 3.5.

Serious buyers regret as winter hits. I didn't expect my efficiency to drop like this. Temps have been 32F-40F and i went from getting about 4.0 mi/kw (that's with A/C on) in the summer to about 2.7-2.9mi/kw in the winter. I used to DCFC once a week since my weekly commute was about 170miles, but now i need to DCFC twice a week. Even after driving the fastest speeds I see are 55kw. Its pretty bad. I was going to move to an apartment with level 2 charging in the spring, but that come any sooner. I just didn't expect it to be this bad.

IDK, I did my homework. LOTS of homework and analyzed it every which way to Sunday before pulling the trigger. Also owning a hybrid car helped me understand just how huge a hit cold weather takes. As cold weather (talking less than 30F) hits our RAV4 to the tune of nearly 40% which actually is about the same as I see as a "hit" with our BZ. Currently in the throws of a pretty nasty cold snap. So, my "indicated" range is in 170 range at 15-20F temps. But, I expected it.
I honestly feel, much of the "complaints" are due to people not doing due diligence prior to pulling the trigger on ANY BEV not just the Toyota.
Even so, I still get a little "blindsided" not so much by the car but by the lack of charger information easily available through navigation apps.

ICE vehicles also take a winter hit. Big difference is a gas station anywhere you go. Same with hybrids.

My experience so far owning now 2 "electrified" vehicles is the "hit" is worse on electrified than straight ICE vehicles. I.E. where my old Highlander 3.5 V6 would typically avg ~20mpg in my mixed driving in warm weather on summer blended fuel (which also has more BTU per gallon). In winter on winter blend that would drop to 17 mpg or so.
Whereas my RAV4 could easily do 48-50 mpg summer, in winter same driving is hard to avg 35. Many times even less. But 35 typically. I think the combination of lower efficiency from the ICE, and the hit the hybrid battery takes makes it even worse.
The BZ especially in this very cold snap we're in has only been doing about 2.6 MKWh as opposed to 4.2 avg in nice weather. Basically about the same "hit" the RAV4 takes.
But with the RAV4 the "hit" isn't as much an issue since I can fill the RAV up easily. The BZ hasn't been an issue since I charge at home.

I rented an EV6 last winter so I'm well aware how the cold effects EVs. Sure it didn't charge in 17min as they promised but it still hit 200kw of speed during the winter. It had less range, but it wasn't a bother to charge. I think the lack of pre-condition is what is killing my experience. I get to the charger and start at 30kw, by the end of my charge i'm at 55-60kw, but at that point i'm already at 60-70% charge.

For any new EV drivers, here are some tips based on my experience. The front defrost (defog) reduces a full charge by 50 miles in my bZ. The regular heaters in Eco mode are about half the reduction. Fan speed seems to make no significant difference, so if you need either you might as well crank it up. Seat and steering wheel warmers seem to have very little to no effect on the battery, so I try to use them instead to increase my mileage. And lastly; only use high octane electricity. (Just kidding). ;)

I tried out a Tesla Supercharger location near me that was updated with Magic Dock adapters. At 42 deg F, with 44% SOC, the Bz4x kicked off at 33kw, and never got above 42kw.

I've done some analysis and in ~30°F weather, if the battery is cold (35°F) then it takes it 40 minutes to heat it up to 80°F. This means that your charge speed can increase for most of the time. Here are further observations. This is a 2024 AWD.
  • You can charge 5%-80% in 1 hour in 30°F weather with an ambient temperature/cold battery
  • After 30 minutes of driving the battery went from 89°F to 81°F (coefficient of 0.00009195)
  • This means that:
    • 1 hour of driving the temperature would be 72°F
    • 1.5 hours would be 66°F
    • 2 hours would be 60°F
  • Based on the speeds I saw when the battery was 60°F at 23%, I believe this means subsequent stops would be 40-45 minutes 10% to 80%.
    • I would expect 60-65 kW at 10% on plug-in. This would increase up to 70 kW and peak around 40% SoC before it starts dipping.
    • This means 20 minutes from 10% to 40%
    • 20-25 minutes from 40% to 80% with a toasty 80-90°F battery
Takeaway: Your first stop should be as low as possible and be a long stop to get the battery warm. Then, stop frequently.

Brutal. The only reason I'm enduring this is that it's free and near the airport where I had to drop someone off. 24 degrees.
