Range question

[borski]

My Tesla just alerted me on the dash when tire pressure was low. Lucids don’t do this?

They do.

I am surprised how many EV owners misinterpret the range shown on their dash. The range shown at any time is based on algorithms that depend heavily on the average range from the last trip(s). If you are driving around town and are getting 4 miles/kWh and have a 80% charge the car estimates a range of 375 miles. this is dead on if you keep driving at the same pace until you drain the battery but all bets are off once you start driving at high speed. I haircut the first leg of any long highway run by 25-30% depending on the weather.

That is not true for the Lucid in my experience. The Lucid will show a range of kWh left in the battery times about 3.7-3.8 miles even if I am averaging below 2.0 since the last charge. My driving habits have very little impact on the predicted mile range on the dash. For this reason I have gone to percent battery so I can multiply it by a number if I don’t adjust habits 2.0 or 2.7 for more conservative driving, and 3.0 for road trips. Keep in mind driving 80 vs 70 is at least a 15% decrease in range. That’s why I use 3.0 so I have some reserve. Driving style can impact range hugely.

We just did a round trip of about 250 mi this weekend using mostly cruise control at 70 to see how close to epa we could get.

Ended the weekend with 3.4 (or 89% or the EPA rating assuming 3.4 x 118kwh, 401miles)

The interesting this is when DRIVING the car, we tend to average 2.8-3.0. So ACC on highway driving produces dramatically more efficient usage. This is great for a long road trip, but given how large the range is, doesn’t super matter for general driving.

I average low 2s on my commute. The above is similar to my experience. Over 3 in easily achievable on a road trip. What I like about the car is you can have your foot in it and still get 70% of EPA on the freeway without any adjustment to driving style. You want 100%, set the cruise to 65.

Our DEP is approaching 3,000 miles of mixed driving, three of which were at 77 plus MPH on 450 round trip mile runs. The average is alternating between 3.1 and 3.2 /Miles/kWh. I do switch to %SOC when on long trips as it is easy to multiply the SOC x 3 to calculate an expected distance left plus a safe 10% reserve. We have taken this trip many times with the 2020 Taycan. While we used to take two 30 minute stops to charge with the Taycan, we now stop once for a 10 minute charge on the way back.

Very helpful. Thank you.

I have been averaging 4.6 on my commute, though it has only been a few days. My biggest losses so far seem to be battery drain overnight.

Not to change the subject from wire size, but these results are pretty shocking. MoniputerLM said they drove 210 miles and the computer said they had 80 miles left (given the story I doubt it would've done all 80). That is only 290mi on a 450mi advertised car. I understand it was cold and it's more than any EV, but 300 mile range still isn't enough for me to switch from gas. 300 miles actually means planning on 210 mile trips (300 * 70%, for running between 10-80% charge), hence MoniputerLM's trip when he/she easily should have made the 300 mile trip. I have a reservation for a Grand Touring and got the email to confirm. I have a test drive scheduled next weekend and I'm going to do my best to get some brief data. But if I can only plan on 230 miles trips (500 advertised * 65% actual * 70% buffers), this isn't the car I've been waiting for. Particularly surprised because 70mph test are showing pretty close to 500mi. And I'm surprised this is "normal." I can't believe people are so happy with their Tesla's if base models are only getting 175 miles (267*65%), and they can really only pull off 122 miles for planning purposes.

And this doesn't just have implications of stopping more often. It also means each stop IS longer. Because 1 mile charged isn't 1 mile, it is only 0.65 miles. You think you're putting in 100 miles of range but it is only 65 miles. So you need to charge longer too.

Am I overreacting? At what point do you get to claim the car is a lemon and send it back or is there fine print saying the car may only get 50-60% of its advertised range?

In case you haven't seen this video, this does a nice job explaining how different things impact range. It shows how speed impacts range, running climate controls at full blast, having "accessories" added to the car, etc. He ran 5 laps on a 2 mile track, to try to keep things "relative" to each other.

Thats a 540 mile range.... Are you driving downhill in both directions Lol

 

[Codyroo]

You can imagine his range could be quite good if he's got climate controls on minimal settings (because of moderate weather) and is keeping his speeds down because he is moving in slow traffic.

Any EV should get phenomenal range if they could maintain a constant speed of 30 mph vs 70 mph..... It would be awesome to hear what GEWC is doing to attain that rate, conditions they are facing during their commute, etc.

If it was 90 degrees outside, A/C blasting, stop and go traffic, keeping close to the bumper of the guy in front of you to keep "dive bombers" out of your lane etc, your mileage would decrease because you are on the brakes a lot and the A/C would be draining the battery the whole time.

If you are on APS, off-peak rates are 8PM to 3PM so you have a long time to charge. You may not need EA very often.

And in a few months, APS off peak will become 7PM to 4PM, even better!

My first EV was an i3 so I got really good it You have to when you only have 70 miles of range. I have also purposefully been driving on non-highways, so lots of stops, in order to get myself used to strong regen again and to learn how the car likes to drive. And I have not been speeding off when the light turns green, like I usually do in my P85. Most of my commute is between 35-45 mph, so I have almost no need at all to use the brake, and I get maximum regen. And I drive with the windows cracked, no AC or anything else. Mind you, as soon as I start taking the highway again and trying to quickly cut over to the HOV lane and speed past all the slow cars until I can cut over to my exit, I have no doubt I will be nowhere near 4.

For a few years I drove a Kia Soul EV, and enjoyed spinning the (front) tires to get up to speed in the HOV lane, once I'd pushed through all the stopped traffic that wouldn't let me in in the other lanes.

I just went over to a nearby (3.5 miles away) EA charging station; 150Kw. When I arrived the car was showing 106 miles remaining and when I hooked up to the charger it showed I was at 26%. 35 minutes later I was at 80% and car showing 356 miles. So 250 miles in 35 minutes. Sat in comfort listening to my book on tape. It started out charging at 10 miles/minute, quickly switched to 9 miles/minute, and then down to 8 and then 7 for the last 5 minutes.

 

[DeaneG]

Nice! On a 350kW station, it should be easy to hit 1000 miles per hour charge rate.

That was a very good video on range impact.

 

[SaratogaLefty]

Wow!! I haven't run my car down that low. I did charge on a 350 in Paso Robles but the car was over 50% when I started and only saw about 230kw max. Did you pre-condition before charging and if so for how long?

Put differently...driving impacts range! I don't plan to spend this kind of money on an electric car to drive it like a Buick. So range is important to me and that is a key reason that I have reserved a Lucid.

Nope totally forgot about precondition. It went higher up to 303 but I forgot to take a pic.

So what is everyone getting for average range? In one week mine is overall 3.8 mi/kwh over 410 miles. I did do a bit of fast driving today, but still got home averaging 4.1, so I'm guessing the lower number is from loss overnight. I have noticed battery drain is quite noticeable some days. I do keep forgetting to lock the car and my keys hang less than 10 feet away, so I wonder if drains while unlocked. I thought the car automatically locked, like a Tesla, but mine seems to only do that sometimes.
