Yes, Tesla too has vampire drain, but who drains more is another debate. Lucid’s “start” button is stepping on brake to initiate all systems.
My DE seems to have more Vampire Drain lately, more that 1-2 miles per day. Not sure why, new software?
I got drained only 7% while out of country for 4 weeks, then I get 1~2% drain a day when I got back home. The difference is my mobile phone is back home near the car, weather got a lot hotter and new OTA updates. Somewhere along the parameters is the culprit or all of above. Right now it seems trivial since charging to 85%+ SOC is like 400 miles+ which can last me for awhile anyway.
I agree and I would like to dig into further, but sadly I have no L2 charge at home, L1 charge is not working for me and I wouldn’t want to EA charge to 100%, so the saga will continues when I get that 100amp sub panel and NEMA 14-50 improvement.
Man if I was a thief and your Lucid didn’t lock with the fob inside it…wohoo free Lucid!
Something is very wrong if it takes 3.5 hours to add 4% to the SOC with a 9 kW charger. This should take about 35 minutes assuming 85% charging efficiency.
Where do you live that has 13c/kW in summer? Here in Houston, our rate is going to 18c/kW now
Yeah any vampire drain replacement I’ve seen when it’s refilling back up to 80% takes about 20-30 min on my 9kw home plug.
I’m glad you did this test and brought this up, as it’s a valid point. However your math only applies if you plug in every night and charge back up to 80%, and really experience drain of 4% while plugged in overnight consistently. I usually plug in once per week or less, and when the car hits 80% and then wakes up in the AM it has lost more like 1-2%, and total energy costs where I’m at (delivery charge, supply charge, efficiency charge, etc) adds up to .18 per kW total, so you’re replacing maybe 2.5kw once per week due to drain which is a couple hundred dollars a year, not $1,400, still not zero but way less than your math estimates. If you plug in every single night though I can see how it would be an issue, and Lucid does recommend doing that, I just don’t follow their recommendation because battery degradation probably isn’t much of a problem with this car, it barely is with 100k mile Teslas that have been mostly fast charged and run down to very low SOC repeatedly (I think InsideEVs test showed 9% degradation over 100k miles).
Cool, I’ll be another data point, I’m charging to 80% tonight too and will see what SOC% it is in the AM as soon as I wake the vehicle up. Here’s what I suspect will happen, I started at 20% SOC so it’s going to only have been charged to 80% for about 30 min to an hour by the time I leave for work tomorrow AM, so it’s unlikely I’ll see much if any vampire drain. If however I plugged in before I went to bed at 70% SOC and charged to 80% then I bet we’d see greater vampire drain because the car had been sitting while not charging for longer.
Check your drain when you get back in the car after work. I find that the drain continues a few hours after a charging session.
That is when I see the drain. It occurs within a few hours after charging and I lose 3-4% of the battery during those hours. If I don’t charge, the drain is only 2-3 miles overnight.
Identical to what I’ve had since taking delivery in May. Every charging session outside of an immediate road trip after unplugging. EA is 5.5 miles from my house, so when I charge I lose ~4% in the few hours after parking in my garage. Charging at home and driving to work is 16 miles, still lose ~4% after parking at my shop. Otherwise, most nights I won’t lose miles.
