Reduced range

Post by AFD » Mon Mar 23, 2020 7:55 am

I’ve had my I Pace for 2 months now and travelled almost 2000km.

Around town the range indicator suggest ~ 400km, although I’ve never let it go below 200km, before a charge, I’ve done two long return trips (mainly highway) during that time, 550km return. Stop over and charge overnight at 7.7kw. The first one saw the car with 52km left when I got home which was fine, but I did the exact same run yesterday and had only 25km left sub 300km overall range. The cars not changed, the roads were the same the car was full on departure, the average speed was slightly faster on the second run at 94 vs 90kph. The temperature was 28C first time and 20 yesterday. So essentially I’ve lost 22km ?

Is it a lottery, is it my speed or is it the temperature? if it’s the temperature will I make it at 10 - 15C in winter?

Or has my battery lost some oomph!

On the second trip your consumption was 8% higher than your first trip (28.2 vs 261). Most likely the increase in avg speed of 4% (94 vs 90 km/t) explains that. Wind conditions, temperature (ambient and battery) are also important factors.

10 to 15 degrees should be optimum for the I-Pace. My experience is that driving style and climate control is the key factors you can control for range. Yesterday I drove 104km at 5 degrees C, average speed 67km/h, ECO mode, cabin temp at 20 degrees and optimum road conditions. Consumption came in at 18kWh/100km with 18" true winter tyres. But I can easily increase the consumption to 25kWh/100km if I turn up the temperature and have a more aggressive driving style.

I run the AC all the time and have not used the heater but I assume that’s reverse cycle AC, rarely gets colds that 10-15 in winter day time so if it’s not so much the temperatures I need to slow down.

This is a regular problem when you get close to zero how many KW does it take to recharge if it takes much less than 80KW try resetting the range meter (GOM)
From another thread
Could be just a GoM reset required ignition on without pressing the brake then press and hold the brake and throttle pedal for ten seconds). The GoM should reset to show a higher range. Then leave the car plugged in to the AC charger overnight at 100% SoC.

Better not to use GOM for any kind of measurement/analysis - still not perfect but better look at consumption and/or SoC %.

In terms of it being a lottery - that is a little bit true as there are many things that impact consumption/range that are outside your control. Wind speed and more importantly wind direction can have a huge impact, road and weather conditions, little or lots of traffic, temperature, sun or rain.

Then there more impacts that are more in your control like driving style, use of AC or not, amount of passengers/luggage, type of tyres, tyre pressure.

Now looking at your specific situation - trip 1 was shorter and more efficiency than trip 2. Trip 2 has higher avg speed but average speed can be very deceiving certainly if 1 trip had little traffic/green lights and others heavy traffic and red lights - the car records trip average speed not driving average speed.
1) 264.4km * 261wh/km = 69.0kWh used calculating with 82kW available battery = 84.2% = 15.8% left for 52km = 3.28km per % SoC
2) 269.3km * 282wh/km = 75.9kWh used calculating with 82kW available battery = 92.6% = 7.4% left for 25km = 3.38km per % SoC

As you can see - GOM is actually more generous with trip 2 despite showing less range left as % SoC wise.

AFD, you're going slightly further than Jaguar say you can at those temperatures and speeds (with those lovely big wheels);

https://www.jaguar.co.uk/jaguar-range/i ... index.html

You should be fine in your 'winter' too. There's very little difference in range at 92kmh (only 13km) between 10 degrees and 30 degrees with the a/c on all the time.

Just another variable, I charged the car on the second trip using a portable 7.7kw charger. Previously I’d only used the standard 2.2kw charger, is it likely the smaller charger trickles a little more into the battery.

Also I gather the car learns as the range is quite different after a long run. Around town I’m always over 400km, on theses longer runs I see 360-380 range after a full charge, quite optimistic?

Did you happen to note how many Kw it took to re-charge on both trips? Keeping track of re-charge is an important aspect since it shows exactly what you took out which is more important than the range and SOC.

No idea, the portable 7.7 zeros after it finished which is a shame.
