8% range increase and 107kW charging imminent?

Post by DougTheMac » Fri Oct 11, 2019 9:33 pm

<t>The following has been posted by Radi513 in the SOTA thread. I thought it deserved its own thread:<br/>

viewtopic.php?f=8&t=2450&start=240#p35833

<br/>
<br/>
In connection with the Drivers Experience event we had at Rudskogen Motorsenter in September, we had a visit by the chief engineer of I-PACE Stephen Boulter. He has been able to answer some questions from both customers and interested parties. Below we highlight some of the points listed in the starting thread.<br/>
<br/>
- Infotainment is not made by JLR, but by a third party<br/>
The infotainment system comes from other model lines and is therefore not developed specifically for I-PACE.<br/>
Due to many extra functions around battery management, charging and the like. the amount of data and processes is significantly higher than for other models. This means that Engineering is working on improvements that will optimize the speed of processing this data by prioritizing tasks and removing irrelevant processes. But the upgrades depend on national standards and equipment variants.<br/>
<br/>
<br/>
- SOTA currently handles only Infotainment. More modules will come later.<br/>
This is absolutely right. Already this year there will be a physical update to be made at the dealer. It will open up for more updates via SOTA. Specifically, from Stephen Boulter, the following will happen:<br/>
<br/>
1. In October we will inform all existing I-Pace customers about a significant new SW update. Through a mixture of real customer data harvesting and a dedicated development fleet, we have been optimizing the Jaguar I-Pace to make a number of improvements:<br/>
• Improved Regenerative Braking:<br/>
Regen can now operate at lower speeds and is stronger at higher SoC. This im- proves the 1 pedal driving experience and efficiency.<br/>
<br/>
• SOTA:<br/>
The battery management, charging module and telematics unit will be updateable over the air.<br/>
Efficiency: *<br/>
We have improved the efficiency of the I-Pace in real world driving conditions, resulting in range improvements of up to 8%. Some of the improvements are particularly effective in cold temperatures:<br/>
In ECO mode, the torque split is optimized for better efficiency<br/>
Higher depth of discharge in the battery<br/>
Optimized cooling strategy to enable the active vanes to be closed more of the time<br/>
Improved cell balancing strategy<br/>
Prioritize heat recovery from ambient at start up, this allows the vehicle to reach optimum operating temperature sooner<br/>
Reduce use of high voltage heater<br/>
<br/>
- Improved charging curve coming (100 kW over a longer register)<br/>
Jaguar Land Rover has been conservative around DC charging from the start. This has been to protect the battery, but after 1 year of experience and data collection it opens up to be able to charge more efficiently. Depending on the car's status (especially state of charge and battery temperature), charging efficiency is defined from a look-up table stored in the BCCM (Battery Charging Control Module). When conditions are optimal (battery temperature 30 degrees and tate of Charge below 10%), BCCM will ask the charging station for 107 kW. In all other cases, the charging speed will be lower and cannot be maintained for long periods. In countries like Norway, the battery rarely reaches 30 degrees. But with large amounts of data collected and experience from test cars and with over 800,000 kilometers driven, Engineering is almost ready for optimizations that will provide more efficient charging. In particular, one should focus on loosening up the requirements for temperature and State of Charge.<br/>
<br/>
- In general, JLR is very focused on improved charging and efficiency (range)<br/>
This is correct. Engineering is already focusing this year on improving the efficiency of charging.<br/>
<br/>
- To fully replenish the battery, the battery must be given the necessary time to balance the cells. You can 'lose' more kWh if you charge the charging cable too early even when the car reports to be full. Smarter balancing algorithms are being worked on to reduce this 'problem'.<br/>
This is correct, it is something that most electric car manufacturers work with and there will be ongoing optimizations via SOTA.<br/>
<br/>
- The maximum theoretical charging speed for I-Pace is 107 kW.<br/>
This is also true.<br/>
<br/>
- There will be an update at the end of this month.<br/>
This update is scheduled to come this month.</t>

Great news then. But they didn't tell us that we were beta tester when we bought the car ...

As long as the cars are constantly improved and not made rapidly out of date I don't mind. It is a fantastic car and I do not regret my purchase.

Happy to see them take this approach and be a real world tester. I just hope the actions match the talk as its been almost a year for me and so far their ability to deliver has been less than stellar. Its time SOTA became SOTA not call the dealer, convince them there’s an update and to send it to you. The car is awesome but let down by the software and lack of SOTA and meaningful updates/fixes in my opinion.

IF this update is correct, the I-Pace could be a 500km car on a single charge.

IF the menders fix my car and it gets this update I will try for it. The problem is, my car already has 3% battery degredation, though can still achieve 300 miles.

Seems like Jaguar Norway wanted to set things straight after a lot of rumours following the event with the chief engineer from Jaguar

Actually, unless you consistently drive 200+ miles a day and/or uses rapid charging all the time, these updates probably won't make that much of a difference to your day to day life. It is indeed nice to have for that one road trip that I do every few months, but saving 10-20 mins every few months really isn't that big of a deal in the grand scheme of things. Having the SatNav to calculate better routes with better traffic data, on the other hand, will save me that amount of time on a daily basis.

Make no mistake, I like the improved charging curve, if possible, I would like my car to have rocket boosters too. :D

But the truth is that I rarely use rapid charging, and when I do, I plan the stops so that I can spend 40 mins eating etc. So the improved charging curve would actually mean that I have to interrupt my meal half way in order to unplug. (Yes, I am the good citizen who unplugs straightaway at 80% SoC to vacate the chargers). Or I could just deliberately use the 50kw chargers, in which case the improved charging curve makes 0 difference.

Everybody has his own use case for the car, but I doubt my particular usage pattern is that rare. And for people like me, the range and charging speed isn't what's stopping me from enjoying the car and recommending it to my friends.

The infotainment system, that's a whole different story.

Maybe it’s because I’m driving in the UK and longer round trips don’t exceed 300 miles or so, but on my rapid charging stops I usually only need an extra 50-80 miles. 100kW charging means that those stops can be very short, not much longer than a fossil fuel stop including a visit to the loo and buying a take away coffee. Perhaps those situations are where 100kW is most useful providing it doesn’t involve a single visit fee per IONITY’s model in which case it only makes sense to fill up.

Do you use a Windows based PC?
If you do then you have been a Beta Tester since Windows 95 was released.

Fact of life when it comes to the majority of software based systems really.
