Route Planning/Charging Advice

[TakeDuo]

I planned a long test route and the map is adding a charge stop when it looks like it can do the entire distance without (at least that's my guess based on real world range). Is it adding the stop because it estimates conservatively using real range that I can't see, or is it assuming a desired destination soc that's higher than needed which in turn is causing it to add a stop? Basically I can't tell why it's adding an 8 min charge even though it doesn't seem strictly necessary? Also I have the EA only toggle on in search but the added stop isn't EA .. I can manually add an EA stop (free to use) but how did it pick that brand .. best combo of fast charge, availability and SOC for optimal charge curve?? Can I force EA only in the auto added stops? TIA!

I did a cross country trip. California to DC. The car added those 5-10 min stops frequently. It was conservative. 15% was my best guess at lower threshold. So, I think the 5 min stop was to get us to a longer destination over the 15% bottom end.

On our trip, I fiddled with adding and removing stops. Like sometimes 3 stops got us to a further destination quicker because it was ~20 mins each instead of 60 mins and a 10 min “quick” one.

The problem with the “just making it” approach is who knows if that charger is full, down or non existent. Somewhere in PA, the car was routing us to an EA that had just closed for upgrades the day before. Thankfully, a few miles off the turnpike there was an EVGo. That’s why I think the car is conservative at that 15% or so when using the navigation.

Thanks. Something's still off as that same trip in my prior EV with less range and lower efficiency would make it and still have 10% (my bare minimum). So the car must be making very conservative calculations. I planned the same route in ABRP and it's adding a similar 8 min stop (from 44% to 66% in 8 mins, which would be amazing!), which gets me to destination with 20%. I'm assuming abrp is using real world range - but even then, I think I'd that trip with no stops and still get there with 20%. And I think I should trust abrp more on the calcs? If we could switch the display to predicted range instead of epa, that would help clarify for sure.

Remember the time on charge is less important than the target percentage. The 8 min is unlikely tbh. The 66%+ leaving that charger is the goal. I did not use ABRP or anything similar. I just plugged in my next destination and let the car do all the math. I never was below 10%. Ever.

I actually found the range on arrival very accurate in the car. Within a few miles or so honestly. It seemed to take into account my miles per kW and terrain (possibly?). I now completely trust range on arrival as a result of that trip.

I cannot recommend enough switching the displayed range from miles to percentage. This gives you a better idea and is much more predictable if you can figure out what your 1% of range is or your 10% of range is for your driving style. Simple math numbers.

Thanks, again! Yup will switch the display to battery % for trips. I'm spoiled as my prior car used Android automotive (aaos) with ev features in Google maps, integrated to the car data. It's range prediction was outstanding and charge stops were well integrated. Biggest help on the lucid will be addition of predicted range on the displays rather than EPA rating, although I have a feeling the Epa numbers are there for marketing purposes. We'll see! Thanks again for all the info.

Same here, it's hard to beat (or give up) having native Google Maps running fullscreen in the car, with integrated SOC management and route planning. I'm hoping that Lucid's AA implementation could give us some of this functionality eventually.

I took a look again and unfortunately the car makes it a little harder than it should be. What I really want to know starting a shorter trip is can I make it there and back without a charge. And the math doesn't tie with the mileage and battery info in the car (even if I look at mileage remaining at destination, and I use starting mileage and trip distance, those don't come close to adding up and there's no display of battery remaining at arrival, so the whole thing can't be calculated fully. also can't tell whether mileage at destination is based on predictive mileage as it appears or EPA rating based on remaining battery). the whole thing is made harder than it should be - we as drivers fully appreciate that EPA rating and real world can differ, so just give us the info to properly plan a trip. or if they are going to make it elegant and do everything for us, at least tell me what my estimated battery be on arrival, for the round trip, etc. anyway enough rant, really appreciate the tips and I'll see what I learn on some longer trips when I take them. meanwhile I'll assume that Lucid is continuing to work on the software and will enhance or if we get the gravity UI that it will include more.

and even if not via google, then replicate some of the features including battery estimation on arrival, battery estimated for the round trip, etc. and if they want to beat the competition, allow us to specify a SOC at arrival and have the car calculate the shortest charging time for each stop or even better configurable for fewest charging stops or quickest charging time (e.g. calculate charges at lower SOC to get faster charges even if more frequent). And even better than that, look at the charging stations en route and optimize for power delivery as well.

Lucid's nav software does do this when you enter a destination. It's normally pretty accurate.

Thanks. Where? I'm on 2.5.4 and regardless of whether I have the display units on miles or percentage, the capacity at arrival is on the main screen as miles and I don't see battery soc on arrival anywhere?
