I wondered if anyone has experienced or has knowledge of how satnav can apparently change the range calculation.
I am in the alps and the last 40k up the valley to my destination is on steep mountain roads. There is an Ionity charger 40k from the start of the steep climb. So 80k from the charger to my destination at the top of the mountain road. Yesterday I thought I should allow say 120k of range from my charge to be comfortable to do the 80k trip. There is an AC charger at my destination.
Whilst charging, when I set the satnav to my destination at the top of the mountain climb, the range on the display dropped by 25%. If I switched satnav off, the range rose by 25%. With satnav off, the range looked about right with 50% charge equating to around 165k range.. With satnav on, that dropped to 110k range.
When I set off from charging with 55% charge, satnav predicted 8% charge remaining at the destination, so around 2k per 1% charge which, on normal roads, is too low.
However, that is exactly what happened.
The only explanation I can think of is that satnav can somehow distinguish elevation/climbs in its range alogorithm.
Does anyone know if that is the case or has had similar experiences?
All insights gratefully received.
Cheers
