Yeah, CarScanner is showing me a 205kW limit with a battery temp of 64F right now. So these aren’t like Teslas where you have to get the battery nice and toasty (but not too toasty) for peak charge speeds. I guess my point is: After a couple hours driving, when you’re using Apple Maps for...

Yea, I’m curious about that too. I always use CarPlay for navigation (so I don’t get the benefit of preconditioning) and my truck always hits 175-180 kW for the first 6 or 7 minutes at a Tesla Supercharger, then 120-125 kW until 80%. AFAIK, that’s as good as it gets. The weather is pretty mild...

Another week another update. They finished the charge port! Service writer called me on Friday with the happy news! Did they diagnose the HV battery, like I asked last time we spoke on the phone? Uh, no, but the charge port is fixed! Did they at least test the very specific symptoms that I...

Door sticker says date is 12/22 (had to find a picture from a few months ago). Current milage is ~47500, but I would estimate I saw the first symptoms around 46k, maybe as early as 45k. The previous module replacement was at 40k miles.

I might as well post my update too: Dropped off the truck last week Thursday. I wrote down my symptoms in the reservation (basically same as Mpi and AntJohn73) and also explained the same verbally to the service writer. To help them diagnose the issue as the HV battery, I also mentioned that...

I was going to try something like this with mine when I got home from a business trip. The plan was to check for a similar “drop to zero” effect at the bottom. But after @Mpi reported in the other thread that his dealer found a bad cell, I scheduled an appointment with a local dealer for...

What if the your vehicle just understood simple voice commands like “turn on/off seat heater” or “turn on/off defroster”? A man can dream…

@Ford Motor Company ping me for a third example.

@Mpi Holy moly, 18% variation! On my way back from Palm Springs I got a 5% power reduction at 25% displayed SOC and 7% reduction at 22% displayed SOC. I think those power reductions are happening at higher SOC than expected? Same as on the way down, DCFC dropped to ~50 kW between 71-73%...

I wonder if the BMS software is incapable of balancing the modules when they are grossly out of balance. Some BMSes only top balance under certain conditions, and it’s possible those conditions are never met when the imbalance exceeds some threshold.. For example: If one module reaches the...

This (and I mean all the symptoms you described here) is very similar to what I am observing in the thread over here. If you get a Bluetooth OBD dongle, the free app (you pay to remove ads) Car Scanner can directly show your cell state of charge imbalance as well as the difference in average a...

Well… I’m back… with another long-winded post ☹️ After 6 trouble-free months I started to get some weird symptoms. The first thing was on a ~300 mile trip down to Santa Barbara, about 6 weeks ago. I charged to 100% the night before. Battery percent started dropping rapidly immediately after...

Nope! That’s why Volts have “mountain mode”. It sets the engine run target SoC to 50% instead of ~5%. You’ll burn down a couple/few bars of battery if you drive fast up a steep grade (say, the Tejon pass). Try the same thing in normal mode (with a depleted battery) and you’ll hit a speed...

Important to remember that’s for a study in Europe. Lots more people over there drive company cars because it’s more tax-efficient to give an employee a car than it is to pay them more. Couple other important factors: Typically, the employee can select a car from a list of several options...

Sounds right to me. I look at the math like this: Assume you want to drive up a 6% grade at 65 mph with a total rig weight of 15000 lbs. I’m going to do everything in metric because that makes the math easier: 6800 kg * 9.8 m/s/s * 0.06 * 100 km/h =111 kW = 150 hp At 65 mph we get around 1.9...
