Thanks for the video 👍 just small suggestion. It'll be cool to have one extra camera pointed/zoomed on the display and have that view in front of non-zoomed display so we can better see and read what's going on there 👍
Very well produced video slanted to the technical side of things..a refreshing change for this type of video. My LRMY will arrive at the local service center in about three weeks. I will install a roof sunshade with a screen and a heat reflector sheet. Between them I will install a thin layer of THINSULATE in order to reduce heat loss in winter and heat inputs during the summer. Heat always flows from a warm body to a cold region also known as the ultimate heat sink. I never look through the glass roof when I’m driving and and I have the same setup in my LRM3. Take care.
Thanks for this video. I am a new 2023 M3LR owner and have not taken any roadtrips yet. It was nice to see the details on the energy monitor. I have driven 544 miles with about 275wh/mi avg. The OAT has been 20-35 degrees and my speeds are averaging 45-50mph. So, I am pleased with this winter efficiency.
Hey John, I just came across your channel a few days ago and really like your videos. I am in Minneapolis and get out to Chippewa Falls every so often in my 2022 MYP so I can appreciate your videos A LOT. I am also a "numbers-junkie" and use the Tessie app to download my driving and charging data into a spreadsheet for analysis. I have some interesting results to share with you if you'd like them. Let me know how we can connect. In any case, safe travels and May The Electromotive Force Be With You (we are roughly the same age so I thought you'd appreciate such a "dad joke" so to speak).
Yes - I love the dad joke! My gmail email address under under the 'about' tab on my RU-vid homepage (not posting here to avoid the 'bots'). I grew up in the Lake Vermilion area and still have a cabin and family there, but lived in St. Paul before moving to Eau Claire. Most of my car's mission is to get us around to those three areas. The purpose of this RU-vid channel is to share knowledge and joy of Tesla ownership - so, yes, I'd love to check out your data sometime. Thanks for stopping by to check out the channel.
@@JohnVanDeVoort Hi John, maybe I am missing something but I do not see an email address on your YT "About" tab. Check your FB Friend Requests / Messenger for a msg from me
Got the FB request! I didn't see anything come across on messenger, but maybe because we weren't connected there yet. My email address is first five letters of my last name, then numbers 058 afterwards @gmail.com. It is somewhat hidden on the about tab - need to click a button to reveal it next to 'for business inquiries.' YT doesn't make it super easy...
The largest factor is that I didn't have a heated garage on this trip to keep the car warm overnight, so the battery was very cold at the trip start. From my understanding, the car needs to warm the battery to 35 deg C (95 deg F) for optimal charging. The trip start was -6 deg C (~22 deg F), and driving in the cold ambient air, so longer charging was needed on this drive. Other times of the year I usually experience about 10-15 min of precondition time.
@@JohnVanDeVoort interesting, it make sense. I had a trip in December it was rainy and cold 4C. Destination a SC 80km away estimating 12%. The car started to preconditioning right at the beginning of the trip I was concerned it will increase significantly my consumption since we were just starting the trip. I turned off everything except the seats heat on medium. I drove at a reduced speed around 80 km/hr, in the next 40 km range gradually increased to 16%. I ended up going faster and with AC on at 22C and arrived with 14%. As you said the main factor is speed! Next time I won't give up on comfort.
John, thank you for the Minnesota/Tesla winter content! We're looking at a YLR and we're in the south suburbs wanting to drive between the cities and Brainerd at 150 miles one-way. Do you think we'd have issues getting one-way on a single charge even when it's below zero? Thanks!
Not at all. I regularly drive between Eau Claire and Duluth in the winter, which is about the same distance. I've also made the trip to Brainerd during the winter (with a stop near St. Cloud). There is a Supercharger at the Arrowhead Lodge in Baxter that is very convenient for the return trip to the Cities.
I'm not an engineer, but found an air density calculator that shows air is about 90% as dense at 25 deg C (77 deg F) as compared with -6 deg C (21 deg F). (these temps are average 'approximate' difference between summer and winter driving in my area). Over that temperature range, it will have a larger impact to drag, but vehicle speed (drag due to speed) and elevation (drag due to air density at different altitudes) are variables as well. Good question, but difficult to answer as far as range impact.
@@JohnVanDeVoort Also no engineer here. But let's give it a try. You found that when going 31ºC down in temperature, the mass of a fixed volume of air goes up +10% (I am also no mathematical wonder.. anyone correct please). I don't know if this is linear, but that on average would be 10/31= 0.3226% more air resistance per ºC down. (if 2x density gives 2x resistance, another thing I don't know for sure). Air resistance is a big factor, thus this little part of air resistance is not to ignore. To make it easy, can we say that 3ºC less = 1% more air resistance?
And one more thing, totally off topic: John van de Voort sounds extremely Nederlands! Are your parents from here? (that is where I live). I don't here Dutch in your voice.
Yes - that is my family heritage. But I'm the 4th generation in the United States. I can speak German (was an exchange student in Stuttgart), but helaas spreek ik geen Nederlands.
Yes : . At -10 °C, the drag force is about 12% larger than at +20 °C, Air density at 20 C = 1.14 kg/m^3 and at -10 C it is 1.28 kg/M^3 and drag is proportional to the air density.
Average speed on the first 30 miles was 60mph, last 60 miles 65-70mph. Drive time is about 90 minutes. I made a quick stop after 30 miles that wasn't on camera for snacks, etc.
