I had the orange turtle at 31%, red turtle at 30%. I would say don’t drive this car at all if you’re going to drop below 40% when temps are below 10*.
I had basically the problem, Saturday but I got the orange turtle at 30% HVB while driving 70 mph heat set to 65F. I had to pull off the interstate and take backroads for the last 10miles of my trip. Its absolutely ridiculous how underpowered the heater is.
While I did not monitor it via OBD, I know what the charging curve is and I know I was well below it for the first 20 minutes. It takes a lot of time to warm up 1000lb of battery 60 degrees with a 4kW space heater.
I understand why you’re skeptical, and I’d like to look at more qualified data...
Yes the faster charging speed more than makes up for the preconditioning energy loss, that’s the whole point. It makes a big difference. Last time I DCFC it was at least 15 minutes before my battery was up to temp and it wasn’t even that cold.
I definitely get better efficiency after preconditioning because the car doesn’t have to waste battery energy to heat the battery to a decent range. Unfortunately preconditioning was pretty expensive, at least $20/month so I stopped doing it every day. It’s a trade off of battery cycles vs...
There are literal scientific studies that show charge percent has a huge effect on battery degradation. Yes people will say 8% is better than 10%, not that it’s a lot. I want my battery to last as long as if can while being as usable as possible.
People will know because they will ask. It’s like knowing the mileage of a used car, hugely important. I wouldn’t buy a EV without knowing the State of Health. Battery degradation is a large factor in EV resale right now and will be super common for people to be thinking about in the future...
