I'm planning my first ever trip (in my (soon to be collected) M3 LR)) to visit family. This will be 200 miles south, then 100 miles east, then 200 miles north (home) over 3 days / 2 night. I will need to get 200 miles on the clock somewhere near Reading or somewhere along the M3 / M40 . . . . what/where is the fastest / cheapest way t do it?
Here's my suggestion
As other have said visit ABetterRoutePlanner. I recommend you use a PC / Screen / Browser, at least initially, to have plenty of screen space. The phone APP is fine, once you know what you are doing, but until then it may be harder because of limited space on the phone screen. Download the phone APP for your actual journey-days.
Choose your model of car. You probably don't need to do any other config, at least initially, but in mid winter (
or if rain / snow forecast for the day of your journey) it would be prudent to put in Temperature and/or Rain as that will impact your fuel consumption. You could put in weight (of passengers / luggage) but that has much less impact on range.
Put in the start location (ABetterRoutePlanner will find it from a reasonable description - PostCode or name of a landmark / building / town / whatever)
Put in the final destination (may be the same as the start)
Press ADD a Waypoint (several times if you like)
For each waypoint type in Postcode / Name etc. You can DRAG the waypoints if you got them in the wrong order.
Press the ROUTE PLAN button
If you choose a Tesla vehicle (M3 / MY) I am reasonably sure that ABetterRoutePlanner will have automatically restricted to CCS Supercharger locations only. These will definitely be your easiest option (
reasonably likely cheapest as well, excepting that you might be able to get "free" at some other places). If all the charging locations you see listed are "Tesla Supercharger" then that will be feedback that it has indeed filtered to "Tesla Superchargers". If you see other brands, like Ionity, then you may want to change the preferences of where you charge. More on that later.
That's your route, and charging locations.
If any of the charging locations require you to charge over 80% then a) you will have a long stop and b) the places you are visiting are a long way from Superchargers. I suggest if that happens you come back here and ask for further advice because, if all your charging stops are a) Supercharger and b) No more than 80% then your journey will be easy. If not then it would be better to consider using other charging locations.
The planning algorithm will aim to get you to arrive at Supercharger at 10%-ish. That's about 30 miles of "detour contingency". For a newbie that might be disconcerting at best, and "tight", or worse!, at worst. I recommend that you charge at least 10% more at each stop (
but try not to include any charges over 80% in your plan as they will be time consuming). At each stop you may find that by the time you've had a pee, and bought a coffee etc. that the charge will be higher than necessary to get to next stop anyway. Dawdling until the car gets to 80% won't take very long. I recommend that you do that anyway, on your first trip - it will give you contingency for unexpected heavy thunderstorm, detours and so on. If you charge to 80% at the first stop, instead of (say) 50% as ABetterRoutePlanner recommends ... well, that will just mean you arrive with more, and at the next stop you can charge to 80% as well. It will take about the same time (charging from 10% to 70% happens faster than 70% to 80%; 80% to 90% is slow. 90% to 100% is very VERY slow)
If you have e.g. an overnight stop and you are going to do some running around there - e.g. sightseeing - then you want to allow some extra charge for that. Also when you set off in the morning you will use some energy to heat the car. So on the leg between Charger and Overnight stop, and from that stop to next Charger make sure you have charged "extra". 1% charge is about 3 miles. So if you need an extra 30 miles then charge 10% extra.
If you get to the overnight stop and there is a 13AMP socket on the wall park there and plug in! You will get about 5 MPH from a 13AMP socket - so a 10 hour overnight stop is good for an additional 50 miles. I've dangled an extension lead out of an upstairs hotel bedroom window to the car park below on more than one occasion ...
If the overnight stop has a proper EV charging station all the better. But don't rely on that, it might be occupied or bust. If there is one, and it is working, you can leave with 100% charge the following morning and save time at charging stops
Ditto for lunch, if you can have lunch at a Supercharger. A 50 minute lunch stop will get you from 10% to pretty much 100%
When you set off on your journey put the destination into SatNav - your next actual stop, not the Supercharger that ABetterRoutePlanner lists. The car will then recommend a Supercharger (
assuming you don't have enough juice to reach your destination). Either that will be the same as ABetterRoutePlanner, or different.; If different you'll have to make up your own mind which choice you will make. if you prefer ABetterRoutePlanner then change the destination to BE that Supercharger. If you have enough juice to reach your destination, but you need to top up before you get there, then put the Supercharger location as your destination. You can zoom in on the map, the chargers are displayed as round circles with a number in the middle (the number of stalls current available), click on the one you want and choose "Navigate there"; or type in the name of the supercharger, into SatNav, instead.
When you are driving use the ENERGY display and the TRIP TAB. That will show you a graph (in grey) as initially predicted, and then a line (in green) of actual energy used, and a projection for the rest of the trip based on that. If you are going to arrive with more than 10% speed up, if less than 20% slow down (I know, those two figures don't add up! If you are 200 miles out then 20% is a good target, once you are within 50 miles you only need to be aiming for 10%). The lower the charge when you arrive the faster the car will charge.
The car will charge faster than your drive ... what I mean is that if you drive faster you will save some time, but it will take less than that amount of time to make up the difference when charging (up to at least 90 MPH), so no need to dawdle if you have more than enough juice to get there
If you are going to use any chargers OTHER than Tesla Supercharger (or if you don't have a Tesla!!) then you will need to have the APP, and quite possibly an account, all set up BEFORE you get to the 3rd party charger. You also need a backup plan (for alternative placed to charge) as 3rd party chargers are notorious for being broken.
