Highway Range & Battery Efficiency

Okay, so you all know that in my first few days of driving my new 2019 Jaguar I-Pace (mostly around town for city driving), I settled in around 39.0 kWh - 39.5 kWh/100 mi., so theoretically, my I-Pace should be getting approx 210-230 mi. of range on a full 100% charge. So, now as promised, I did a nice long, mostly highway drive today to a customer's house and back. Here are the stats I experienced in my I-Pace today for highway driving (pictures attached):

Vehicle set to: Normal, Comfort Driving Mode, nothing on (no A/C or cooled seats today as we had a cold front come through last night and it's a crisp, "cool" 67 degrees F, lol! ) except I had the radio blasting the entire time. Cruise Control set to 77-78mph but the car kept adjusting the speed based cars in front of me, etc. The Air Suspension was set to Normal ride height (can't verify if it did in fact lower as it's supposed to for higher speeds).

Total Miles Driven: 113.3 mi. (about 105 mi. on the highway)

Total miles left according to the vehicle: 77 mi.

Average Battery Usage: 44.1 kWh/100 mi

So, correct me if I'm wrong, but it seems that with normal driving on the highway in regular weather conditions, I should theoretically get a max range of approx 190 mi., correct? Maybe a bit less if I have the A/C and Seat Cooling on...so likely 180 mi. I would imagine. Does that seem fair to you guys? Thank you.

Thanks that sounds about right for those speeds. In fact it seems to indicate a pretty good aerodynamic performance. On my other BEVs going 77-80 would cause a more significant range hit. If you are ever bored and want to try you should reproduce the same trip around 60-65 mph.

I get 204 miles:

90kWh battery capacity / 44.1kWh consumption x 100miles = 204.1 miles

I would be ok with range in this ballpark.

Yes, I've always said that if I can can consistently get a max range of 180+ mi. in my I-Pace, then I'm good as the most I'll drive in one day is typically about 150-170 mi. I would rather have 20+ mi. to spare when I get home rather than having to find a Fast Charger and stop for 45 min. or longer. And, again, that's driving in Comfort mode rather than Eco mode.

FYI - although it's a 90kW battery, the actual usable battery capacity is 84.7kW (so 84.7 / 44.1 = 1.92 x 100 = 192 mi.) ...

I think only about 82kWh of the 90 are available according to testing by Bjorn Nyland (Jaguar says closer to 85kWh), hence the 180-190 mile range.

Okay, so this screen shows slightly different information; even better 43.6 kWh/100mi. efficiency instead of 44.1 kWh/100 mi. Here ya' go...

BTW - anyone know what the 7.0 kWh is indicating? Is that how much of the small accessory battery (for the radio, HVAC, etc.) used? Thank you!

I think the 7kWh might be the regen during your trip.

Here's my stats for Trip A.

Interesting to me is if I take 89.5kwh battery / 41.8kwh consumption * 100 I get 214.11 miles and my dash shows estimated 215 miles of range at 100% charge.

Also, not sure if anyone is interested, and I'm not saying you need to do this, but I got the steps for how to reset your battery. The dealer was instructed to do this for my car because it was the demo car and at full charge my estimated range was showing 195 or less. The engineering team told the tech at my dealer they thought it was showing this low range because they car had been used for test drives. I haven't done the reset myself since the dealer did it last week.
