"High" and "Very High" settings are only for mild off-road, huge speed bumps and transitioning from a steep slope where you might scrape the ground.
And to let elderly inlaws get out of the car ... they hate getting out of my (coil springs) MS
I was just exploring the options to reduce the stop/charging times to the minimum. I think I will have to alternate the stops (North/South) for every alternate round trips get the efficient charging time.
I wouldn't worry too much about optimising the efficiency of your charging time, although things I factor in are:
Don't "pair". If a car is already charging at Stall 3A then do not plug in to 3B (and vice versa) [second car to arrive gets a lower charge rate until first car tapers/leaves]. If the only stalls free are "paired" then [if you can] choose the partner who has been there longest. I park up and bag a space, and then talk to drivers [if they are in their cars] and move if it seems appropriate. But I have had-to-wait just once in 50,000 miles of driving, and had-to-pair-and-moved only on a coupe of occasions. In practice I rarely even have to pair.
Stop on the return trip, not the outbound. On Outbound I might be delayed (all stalls full, paired, etc.) which would make my arrival time at Client unpredictable.(Of course if you don't have range for the outbound then charging is a necessity Natch!). So I chose Model, and therefore Range, so that the trips that I routinely do I would have enough range for "Get to client AND back to Supercharger, even in Winter"
The driver needs a break
So on days when I drive more than the 220 real-world mil range I'm OK with that. Actually mostly my returning-home charge is probably only 5 minutes, maybe 15 at the absolutely most (a day with a 300 mile round-trip). A Pee and getting Coffee takes longer than that ...
Charging, on the way home, at the "nearest to home" Supercharger (when you have a choice), means that the Trip Consumption graph will be giving you a very accurate prediction of energy-needed [to complete trip], so you can charge the minimum to get home (and then recharge, overnight, at home).
Also, charging at "nearest to home" location means your battery is lower SoC. Battery charges at linear speed up to 70%, and almost as fast to 80%, and then MUCH slower. So only charging your battery to 70%, or 80% if necessary, is the most time-efficient - hence stop later in your journey, when battery SoC will be lower. The percentages are true for all models [give-or-take], so a 100 puts on 33% more MILES in the time, compared to a 75 (but above 80% SoC they are both about the same)
If you charge earlier in your trip and then hit traffic, and have very economical consumption for half-an-hours frustrating drive
, you will arrive home with spare energy, and have wasted some time at the charging stop.
Coming off a motorway junction, getting to the stall, jumping out and then the reverse to get back onto the motorway adds 5 minutes to your journey (same if you had to refuel an ICE of course), so multiple Supercharger stops have that additional penalty.
Reducing speed (not that I ever do
, except if range is critical) is an option. But you are increasing journey time, so as long as you can get to Supercharger you are better to press-on. I've got home at 2% once, the weather was foul and cost me a lot of range ... not an experience I want to repeat!
If you are tight on range pull in behind an Artic. Even on cruise follow-distance of MAX the consumption saving is worthwhile - and of course you will also be at the max highway-speed for HGV and temptation to go faster is removed
I've done that a couple of times where my nearest , easily reached, Supercharger was a detour on another branch of the motorway which was going to add 15 minutes to my journey time and I was stretching-range in the hope of making the Supercharger on the more direct route. At the point at which I got to the junction-decision I had the preferred Supercharger in Satnav so I could see the Trip Consumption Graph as to whether I was going to make it ... so decision was easily made, and safe.
If your life involves having to do emails then stopping at Supercharger, and doing emails, is same as getting home, sooner, and then doing emails, so can be a time-neutral thing.
