Highland Range

[tivoboy]

EPA and WLTP are totally different range metrics.

Display is always EPA. And not even that as of late.

Anyway it does not matter. Energy and efficiency.

Miles are units of energy. You just have to determine the energy content per mile which is different for every vehicle model. Or just determine your total energy and ignore that detail.

WLTP is so far from being accurate that it's not even funny. Way off even from the EPA estimates.

But, is it accurate for what it is TRYING to represent?

That depends on what you mean by what it is trying to represent.
If you mean how many miles you can actually drive, it is not very accurate, and way too optimistic.
But as a representation of how much energy is in the battery, it is as accurate as any other metric, (EPA, etc.), as long as you know the conversion constant in Wh/mile that it uses.

What indicated range are people getting on the highland after charging?

My 1 day old LR is currently showing 203 miles at 67%. Multiple that up and it would be 303 miles at 100%. That’s a far cry from the advertised 390 miles.

I suspect there is some calibration to be done by the BMS before the quoted figure settles down, however meaningless it may be.

My 2021 LR shows 245 miles @ 75% which would give about 327 at 100%. Originally showed 335 miles at 100% when I picked it up 16,000 miles back.

Well I simply mean that WLTP as a measurement set, is quite different than the USA EPA measurement set… and that WLTP is higher is an indication of much lower speeds, more time at those lower speeds. It’s not just a European or different implementation of the EPA test suite. so, for what IT represents, is it off too? It’s certainly going to be higher, but then driving in Europe is different than in the USA as far as miles travelled on what type of highways, city speed limits, etc..

It is very meaningful. It tells you the very accurate (within a few % nearly always) estimate of the energy content of your pack. It’s the best estimate in the world for your pack.
