I believe you are confusing charging the battery with the car’s predictive range. You don’t charge to a certain mileage, you charge the battery to a percent and then the car provides a theoretical distance to empty. I don’t know how Tesla arrived at their theoretical prediction, but the Jag is a ‘learning’ algorithm, so your theoretical range is going to change based on what Jaguar has collected in data. Your charging changed and you haven’t ‘lost’ range, but based on your driving history you are seeing a more realistic range prediction
Yup, I think your right. I'm just use to always seeing a certain mileage number after 100% charge and feeling like that's what I got on long road trips. With the I-Pace I have not taken it on a long road trip and have not depleted the battery. I also did not do any proper tracking when I had the Tesla. After reading the article from What Car? on how they did real range tracking I can see where you guys are coming from and where I gotta be wrong.
So in their test they see 253 as real range on the I-Pace. Right now after a 100% charge my I-Pace is showing 213 range (which I understand now is estimated). So lets say I want to go on a long road trip, say 300 miles in distance. With the short in town trips I've been making and current driving behavior, environment, etc. the car estimates I will get 213 miles. So would I see that possibly increase if ideal road, weather, driving conditions, etc and I may get closer to the 253 real range number on the long road trip? I know I'm probably missing some important details here, but maybe you see where I'm going and that really I'm trying to see and understand the range. So when What Car? and others state real range of 253, 240, 234, etc (all numbers I have seen quoted) I'm not understanding why I'm not seeing that number after a full charge. It's a bit confusing to me as you can probably tell. When I jump in my car, I see 211 or 213 miles and I think, "that's it"?
The service manager at the dealership I'm working with is also confused on how the range works and he is working with someone from the Jaguar NJ office, which apparently is or one of the main offices. Yesterday he said an engineer told him that the main issue they are seeing for not getting the quoted 240 range is not using preconditioning so that the battery is at the right temp. He stated the ideal temp is 80 degrees and range increases when operating at ideal temp. I don't know anything about the preconditioning. I didn't turn it on because I don't have a set schedule when I use the car. To me it seemed like you had to set each day when you plan to take the car out, but maybe I'm not understanding that.
