Alpha Feedback - Jaguar I-Pace

Recommended Posts

To verify and improve our models we need your feedback.  There's many ways we could use help if you actually own one:

  • Drive a plan and compare it to the actual battery used.
  • Drive a plan with the browser active, and update your actual battery percentage in the browser.
  • Contribute data via OBD or other methods.

The best way to improve the data is to provide data directly from the car.  Connecting your car not only improves the models, but allows you to follow up directly in the car while driving! We have several ways of doing that, but we need your help to figure out what will work with your car:

  • An OBD reader can be used in concert with a custom app like LeafSpy, or a PID list and Torque Pro.
  • If your manufacturer has an API to access data from the car we can set up access to that API, like we do for Tesla

If you're familiar with either of these, contact me at jason@abetterrouteplanner.com and I'll help figure out what we need to do to connect your car!

Thanks for providing feedback!

Hi,

no one out there yet using ABRP with an I-Pace?

I'm going to get one 2nd half of June and I am eager to using ABRP. I have used the planner some times offline to estimate travelling times for certain trips that I want to make once I have the car.

I wonder how I could connect the car to ABRP. I have got an OBD2 reader. Is there a known way to connect ABRP to the I-Pace?

Best regards,
Harald

If there is, we don't know about it.  Of course, if you're technically savvy you could try exploring one of the methods that have worked for other vehicles.  With OBD2 you could reverse engineer the manufacturer PIDs:
https://mechanics.stackexchange.com/questions/39093/how-to-reverse-engineer-the-manufacturer-specific-protocol-on-obd2-for-acquiring

Or if Jaguar has a decent API we can explore that option.

Thanks for the hints, I can try once I have the car.

Meanwhile I have found that there is an API (not documented by Jaguar) for the Jaguar InControl App (JLR Remote Car API). Somebody reverse engineered and documented it in order to build a Python control interface on top of it: https://github.com/ardevd/jlrpy 

This goes to a JLR server, I am not sure how responsive it is. Don't know whether this is helpful.

Hi, would like to contribute. Do you have an overview with data needed?

Last 3400km 27,4kWh/100

11040km total, trying to get the total data available.

That JLRpy tool seems like a perfect fit for the job!

When I or Bo have time we'll build an implementation, we're also not opposed to some help implementing.  Much easier to do when you have access to a car and can test with live data.

Hi, this is great news. I would be willing to help. I am not sure about programming, that depends on language and environment. Definitely I can help with testing, as I will presumably have the car by end of next month.

My experience is that in suburbs travelling 25km to/from Warsaw everyday, I've got ca 22 kWh/100km efficiency and while travelling 140km outside Warsaw using mixed roads (half express/highway speed up to 140 and half national road, speed 100-110) I spent 25-28kWh/100km.

If you use Jag Api to create their standard "Incontrol app" I'll be glad to install it.

On the Jaguar I-Pace, it defaults to 100% SOC instead of 90% like Tesla.  There is no option for partial charging, nor is it needed.

Use 2.5 mi/kWh as an average consumption.  I'm 2.65 mi/kWh driving aggressively for 7,600 miles at speeds of up to 127 mph (limiter) and some track use and dragstrip use.  Typical cruising speed 77 mph.

DOH!!!  I had planned a ABRP route for the I-Pace, and it had me stopping 45 miles from home on a 146 mile segment that I had driven a few times before, so I looked at the settings to figure out why.  

Obviously, I cannot retrofit the data into the software.  But my car did save the most recent trip of that segment which involves a ~4000' climb/descent and 146 miles.  It recorded 2.60 miles per kWh at an average speed of 81 mph and 75-91°F.  A trip with less than 2000' of climbing of 151 miles was 70 mph average (ACC set at 77) at 32-44°F was 2.65 mi/kWh.

Hi there. I have an i-Pace First Edition and live in Scotland. I have used and been thoroughly impressed by ABRO to plan a few longer trips. I don't do many, but for the couple I have done, ABRP was excellent. It even precisely predicted I would arrive at a charger with 34% SOC after setting off with 90%, so I'm very impressed for an alpha model.

I have some experience with the I-Pace's API, having used it to create a series of Siri shortcuts on iPhone to allow the use of voice commands to control certain aspects of the car (such as locking, unlocking, checking tyre pressures, starting a charge and starting the cabin preconditioning). I wouldn't say I'm an expert coder by any means, and I am also not a high milage driver with frequent public charging stops. But I do have a test vehicle and some experience working with the API. Happy to offer whatever help you need to get the API working with ABRP, which would be awesome. I have no knowledge though of the inner workings of the SatNav and how to pass a route from an app to it.

 

However, I am happy to do what I can, even if it's just offering a test vehicle!

My own experience with my I-Pace after 10 000 km is that adjusting the ABRP reference consumption for the I-Pace from the stated 271 Wh/km to 255 (approx 5-6% down) brings the estimates spot on my actual consumption data for longer trips during summer (at approx 20 deg). It also match very well at lower temperatures (around 5-10 deg) and rainy conditions with studless winter tyres. But this is probably something each and everyone must adjust according to their own driving style. I usually follow the speed limits (I often set the ACC to speed limit + 10 km/h). Great tool! Hope for an integration with the car at some point. More than 3300 sold and registered in Norway by now.

Since beginning of July 2019 we are owner of our first EV - a Jaguar I-Pace.
During our first EV-holiday trip from North Rhine-Westfalia to Sylt I used ABRP in parallel to my own "safety" tour planning (including two pit stops).

It turned out, that the default reference consumption of 271 Wh/km (at 110 km/h) is much to conservative.
APRP forcasted 14% SOC whereas we reached Bremen charger with 32% SOC !
(22" tires, tailwind, 120-130 km/h speed, 214 km distance, 112 km/h average speed)

Because of this lesson I decide to "fine tune" the reference consumption (260 kW/km at 110 km/h reference speed),
drove a bit faster 130-140 km/h and a longer distance of 264 km - unfortunately we had a jam and lost approx 20 minutes.
(98 km/h average speed, ABRP forecastet 12% SOC (Warning! Speed limit at 110 km/h), reached the Bremen charger with 14% SOC).

As Satman wrote I am hoping for an Android Car integration of ABRP.

I have an I-Pace. Travelled 46.000km in 1 year already.

I always put 225 as reference consumption and that is pretty accurate.

Thanks for the feedback, @drPhil and @Yetiman - Sorry I missed it earlier.  We do intentionally make our alpha models a little conservative, but I think that may be a little over-conservative.  When I have some time I'll check back over the I-Pace model and see if I can improve it a touch.

I use 400Wh/mi in my I-Pace at 65 MPH on more or less level roads.  I do have the 22" wheels and that seems to cost me ~10%

Hello I-Pace enthusiasts

I have a 2019 I-Pace first edition and it is mainly used in the city.  I did a trip this week and compared my actual trip with ARBP's plan.  ABRP was very accurate. 

The Plan was as follows

 90% Start Charge, 42% End Charge, Distance 146 Km

Actual

100% Start, 52% End, Distance 128.8 KM average speed 89Kmh. 

 

Unfortunately I didn't use WattCat to track actual power consumption.  I will do that next time.  

 

Kudos to the ABRP team.

Since we now have new app where it is easier to support different live data types, I got curious about the I-Pace API. Has anyone used it for anything? Does anyone want to lend me a token for your I-Pace if I take a stab at integrating it into ABRP?

Ideally, this could mean live car data without any third party HW or SW, just like Tesla.

I’ve used it. I created voice commands using Siri to precondition the car, lock it, unlock it, check the current SOC, check the tyre pressures and a few other things. It works great.

I was going to check this out and let you know. I’m going to work in a couple of hours. I know it doesn’t update the location while the car is moving but I think things like SOC are updated. But I’ll try it out on my drive and let you know. Also, the API issues time limited tokens, so every poll of the API needs a login. It’s fine but it’s not the fastest responding API in the planet. Fast enough for an SOC poll though. Wouldn’t affect the calculations noticeably. What would you need? I assume all you’d need is SOC, as the location could be obtained from the phone exactly as it is now. Would you need anything else?

Just heard on Twitter that it only works when the car is not moving - is that still the case?

I just double checked. The SOC and other values update. Only the location doesn’t. There is a “trick” to it though. You have to send a “force health check” command first and then poll the API. But location would have to be obtained from the phone’s GPS as that will not update while the car is moving.

Do you know if instantaneous power is available? That is necessary for calibration. But yes, SoC is the most important part.

Ah. Unfortunately power is not available via the API. I know you can get it from the OBD port but I don’t know the can bus codes.
