The aero advantage can be real but only if you drive within a couple of feet of the back of the vehicle in front
That hasn't been my experience - but maybe I'm kidding myself? It definitely has the benefit of preventing me nudging the accelerator a bit 'coz 50 MPH IS SO BORING!
Maybe I should try 50 MPH with nothing in front of me and check what wH/mile I get (compared to behind-a-truck)
When I've done it I chose a tall vehicle, and set TACC to max follow distance. So I'm definitely not in the "attached"! follow-range.
there is an increased risk of stone chips, nuts and bolts and other things falling off the lorries and causing windscreen damage
Definitely. I've had way too many replacement Tesla windscreens, and Autoglass has been problematic every time (even without the current dearth at Auto
Glass)
Whenever I'm driving then unless I have overtake opportunity I follow on max TACC distance, or more than that if I an on ManPilot.
Single windscreen damage would wipe out years of such range savings!
When I have done it it wasn't for the moeny savings, it was because back in 2015- there weren't many places I could charge, and if I did something idiotic like missing a junction and having to get to next and double-back, then I had to do it on the original juice-allocation
Anyone found a decently efficient way to do this?
I take the view that I need to do some planning for a trip (e.g. across France, rather than "I'm nipping to the shops"
I do that in ABRP.
'I want to drive 2 hours between stops'
Can't help with that, per se, but my experience of driving across France was that Superchargers were rarely placed such that a leg would be 2h30m (which is my absolute 100%-10% distance at 130 KPH), so in practice stops were mostly 1h30m to 2h00m, and a few a bit over 2hs. Obviously that interval gets longer with time as more Supercharger locations are opened.
'I want to drive no more than 6 hours in a day before stopping for the night
I think that, along with "where shall I stop of lunch" is doable.
Our trips are either leaving midday or later, and overnight en route, or leaving at 7AM or earlier and doing the trip in a day but stopping for a decent lunch.
So for a hotel stop I'm looking for a hotel at around about our stopping time. We want to get to hotel by 7PM so that the restaurant is still serving food
I set the DEPART time in ABRP, so its list of stops is actual-time for my trip. Thus I can see roughly where we will be 7PM and then I look for a hotel nearer to our start point than that.
Then add that as a WAYPOINT. Also (assuming it has charging) set it to 7kW and the depart time as 07:00 the following day. ABRP will discover that the battery will be full by then
Similar for Lunch - check were we will be at 12:00 and then look for a lunch location further away than that (but if it is more than 13:00 then that's probably too far). Then put that in as a WAYPOINT. For me this will be at a Supercharger (not a destination charger), so I will get from 10% to 95+% within an hour - I just need to eat my meal within that time

) Set the WAYPOINT for the departure time (e.g. 1 hour) such that ABRP will discover that charging has reached 95+%, otherwise it will be wanting to leave at 70% charge.
For both the overnight and lunch stops I set the ARRIVAL % at 10% - I want to arrive "empty" so that I maximise the charging whilst I am sleeping / eating.
Then I fiddle with the stop-time at the port e.g. travelling by Chunnel I'm going to top up on the way out, and on the way back I'm going to fill enough to skip the Sevenoaks Supercharger as everyone else coming off the train will be charging there ... I have a note of what %age I need at Calais to get to a charger nearer to home, and also a figure to get all the way home. Depending on when I get to Calais, and the time of train departure, I'll charge somewhere between those too (missing a train if necessary - and provided they haven't fallen to "hourly")
Telsa will throw it all out the window if you put that into its nav in the car
Yeah. Particularly if I have decided not to go the most direct route. I put a DESTINATION in which Tesla will match with ABRP. That's likely to be a specific Supercharger, or a Lunch / Hotel stop.
I find ABRP to be a bit cautious on its planned stops, often recommending stopping earlier than I may need to or for more time
I find ABRP very accurate. My suggestion would be to fiddle with the %age over-speed, or the "wH/mile at 60MPH" figure until you get predictions that match your driving style.
