RE: Scary GMC commercial

While it is "hands free" the online info indicates the onboard camera also pays attention to the driver and pretty much checks to see if you are paying attention to the road. if it looks like you get warnings, followed by the vehicle slowing down, Reading the description it's more like an extension of active cruise control on vehicles coupled with lane keeping assist. and then lidar and other info to keep track of the roadway. That’s pretty much it. The Tesla system is different but provides similar level 2 facility. Unlike the GM super cruise though, it is a hands on system. If your hands are off the wheel too long (20 to 40 seconds) you get warnings and eventually it will assume your incapacitated, bring the vehicle to a stop and turn on the hazards. If you violate the rules too many times it locks you out of the autopilot system until you stop the vehicle and exit the vehicle. The tesla system uses visual instead of radar and lidar. Pros and cons to that. The pro is that it works anywhere on most roads, or at least the ones with lines. It recognizes bikes and pedestrians. It can not be used in construction zones etc. Different manufacturers have different approaches. Supercruise definitely seems pretty cool as well.

RE: lithium question

To be pedantic, there are almost no EVs with LFP batteries except a few homebuilts. All manufactured EVs use some other lithium chemistry, typically lithium cobalt. LFP (short for Lithium Ferris Phosphate) are less energy dense, but much more fire resistant. I'm just pointing this out because many people will say the lithium batteries are unsafe and burn, just look at the Tesla and Boeing fires, without understanding the difference. Hmmm. Might be a misunderstanding of terms on my part. I’m not an expert. Presently all the Tesla model 3 SR plus models sold in China and Europe are using LFP batteries. The US made model 3 SR plus (now just called standard range) are available with the LFP battery. They are a little slower and heavier. Presently the LFP battery for these models come from China but the Tesla Nevada will also be building these in the new year. This is a fairly recent development. All over the last 3 to 9 months depending on factory. Heads up, all the long range models still use the normal Tesla batteries. They are not LFP. Lithium cobalt etc. https://www.greencarreports.com/news/1133942_tesla-plans-shift-to-lfp-cells-for-model-3-and-model-y-likely-with-us-production

RE: lithium question

EVE LifeP04 cells are 10% to 90% for 3500 cycles, they should still have 80% capacity at that point. If so these should outlast me. I think your missreading that a bit.. the industry standard is that the cycles they list are based off a 100% usage. they recomend 10-90% use range and that will extend your cycle life possibly up to 5000-7000 cycles, before you reach that 80% threshhold. then that 80% could be maintained for another 10 years or longer, if you treat them good. Steve Yep. This is why Hertz rent a car is buying 100,000 base models of an EV that uses LFP batteries. An expected battery lifetime of a million kilometres vice other chemistries. You can pretty much run LFP to zero frequently without as much worry of damage. 10 to 90 is much better though. The sacrifice is they are heavier and performance suffers a bit from the higher end models. We are kicking around the idea of putting something like a battle born in our new little trailer that comes with 2 x 6 volt AGM’s. The cheap skate in me says live with the AGM’s and wait a few more years and the price delta to come down. Guess we’ll see. haha AGM, up here, are more expensive that some of the new LFP on the market. and if you can hook up a four 6V battery sety up in your camper you can build your own batter setup with prismatic LFP cells which is so much cheeper. Battle born is way over priced now, there trying to hold on to the prices they set when they were only one of 3 competators in the market and I believe they all agreeded on a price range. Steve Yep, they are pricey. But am I right? You seem to have a good handle on this. The trailer comes from the factory with 2 x 6!volt AGMs. Would an LFP 31 not be giving up a bit as far as useable amp hours? They are in a heated area so that’s not an issue.

RE: lithium question

It seems a Lithium battery is kinda like pregnancy…If you’ve never experienced charging or discharging one, it may be a bit difficult for the uninitiated to relate to - occasionally, a few imaginary red-flags tend to find resonance… 3 tons :). Also just found out that the new trailer will come with a “lithium ready” converter which is new for this year. So I guess that is good. Now leaning a little more that way. Still seems a shame to remove two brand new 6 volt AGM’s. They are mounted inside under the bed just behind the axle. If I replace them with a battle born 31 I believe I’ll lose some useable amp hours so may have to go with two BB’s. Ugh. At least they will be where it’s wam. The hydronic heat appliance is in the same space. :) We’ll see how it goes.

RE: Lithium cost keep dropping!

"The trailer comes with a 1200 watt inverter and is not hooked up to the microwave so I don’t see a huge load from it." Some newer Rvs come with an inverter that is meant to run the res fridge they often come with now. Makes off-grid a challenge. Yes I’ve seen that. But in this case it is a 3 way dometic. I’ll wait to see how much power it uses. It’s a small trailer and the heat and hot water are hydronic, so no furnace blowers etc. It has a 163 watt solar panel on it as well with room for another similar sized unit. Until we get out there I don’t know what to expect. Our first long trip we’ll be up your way. Starting in the Okanagan, following the gold trail up highway 3 to the coast, then a few weeks on the island starting in Victoria, tge. Up the island and the inside passage to Prince Rupert and then points unknown heading east on 16. We have a week or two of dry camping with friends as well but will probably bring a little 2 K propane generator with us. Should be fun. Thanks for the info.

RE: EV's I know there are folks better versed than me in here

GM's Cruise Starts TestingThere are already autonomous vehicles driving on the roads in certain towns. Not to mention winter driving, snow, rain, other conditions. It's happening now in testing and the test are going well. With Lidar, Video, thermal, radar, sensors they can tell the difference between a person or an object. So if the choice is to hit a kid or an oncoming car or tree, the car will know which one has the least amount of potential impact for the driver or other humans. There are tests just like this going on right now all over the world. I work in this industry and you would be surprised at the level of testing that is going on. Autonomous trucks will come before your average car because they can move goods across wide areas with little impact. Autonomous shuttles are here now in Vegas and business campuses across the country. There’s already some pretty cool videos of super cruise on YouTube. Pretty impressive.

RE: Lithium cost keep dropping!

Depends! :) Relion says: "More Usable Capacity 25-50% more capacity than lead-acid equivalent." Many say 100% is usable with LFP, but many users here like doing 20-90s for 70% range in real life, so that compares with 50-90s using 6s at 40% range. You could do 40-90s at 50% range with your 6s too. 70 is 30 more than 40 and 30 is 75% of 40. 70 is 20 more than 50 and 20 is 40% of 50. You also have "inverter usable" vs "furnace usable". The LFP stays above inverter alarm 11v to a lower SOC than 6s do. But you can go lower with the 6s and still run the furnace even though you can't do inverter anymore at that lower SOC. That last explanation using the inverter and furnace makes a lot of sense and gives some clear context, at least for me. Our new trailer that arrives in a couple or so months has two x 6 volt AGM batteries mounted under the bed. I had thought of switching it out for a battle born group 31 but I’ll see who’s it goes. The trailer comes with a 1200 watt inverter and is not hooked up to the microwave so I don’t see a huge load from it. Entertainment centre and a plug by the bed seems to be the only thing it’s hooked up to. Kinda wish it was hooked up to the microwave. That may be our first mod. We’ll see how it goes with the AGM’s but I’m not adverse to swapping it out with a battle borne. Thanks for the explanation.

RE: EV's I know there are folks better versed than me in here

... Tesla exports the majority of the cars it builds in the US. This wouldn’t be possible if Tesla didn’t import raw materials from other countries. I wish you could back this up with Tesla investor data. Like real SEC reports. Tesla only provides world-wide production and sales information. Tesla does not provide country level data like other vehicle manufactures. Would be Yah. True. Tesla does not report sales by country. Straight up, my numbers come from an investors forum I participate in and the number I gave was for year 2020. Those numbers are derived from adding up sales in other countries and subtracting from total sales. I’m sure they are approximate numbers as there are no official numbers. I think export numbers for 2021 will probably be considerably lower as Tesla China is now fulfilling a lot of those markets. And in 2022 Tesla Germany will fill a lot of the European market demand. Tesla Texas is expected to cater mainly to North American demand. The hope is that this will trim the 8 month waiting list for cars in North America. So yes. You are correct. I can not verify those numbers. Cheers.

RE: EV's I know there are folks better versed than me in here

I just read my previous post. A correction. The 2170 cells are used in the 3 and Y. Made in Nevada. The 1865 cells are used in the S and X and are imported from Panasonic Japan. The packs are assembled in Nevada.

RE: EV's I know there are folks better versed than me in here

Tesla's supplier of batteries are made by Contemporary Amperex Technology Co out of China. The Lithium used comes from mostly China but also South America. The Lithium mines in the US do not supply enough Lithium for cars, so not used by any car battery manufacturer. I have been researching Lithium battery companies for about a year, and this is what I read every time I come across info on EV's. Tesla battery packs for cars built in the US are built under contract by Panasonic in the Giga factory in Nevada. Raw materials and some 2170 cells used in the S and X are imported from other countries just like any car manufacturer. Some new standard range model 3’s can be optioned with an LFP battery pack built in China by CAT. The Chinese Tesla factory builds Teslas with battery packs and cells from China. Many from CAT. Tesla exports the majority of the cars it builds in the US. This wouldn’t be possible if Tesla didn’t import raw materials from other countries.

RE: EV's I know there are folks better versed than me in here

I didn't listen to the entire video, but he left out some important parts - not American built. First, electronics don't come from America - he mentioned that, all cars have Chinese built components so Tesla is not different, although they might have more electronics than other cars. But, how about the batteries. These come from China. They are shipped to the US in ships, not unlike shipping oil to the US from foreign countries. Tesla is building a US manufacturing plant, but the Lithium and other hazardous materials in the batteries will be shipped from China and South America to the US. What happens if one of these ships sinks? Lithium does not float like oil. What will this do the oceans? There is not enough Lithium in the US or in the world to support the batteries in EV's. It is not a renewable resource and is not as abundant as oil. I know they are working on new battery technologies, but none have been found to be as good as Lithium. We can hope they get better, but that is a ways off for now. Lithium is more hazardous than oil and LI-ION batteries are catching fire burning down garages and houses. How many times has an ICE burned down a house for no reason other than just sitting there? Buy American - but buy American and don't hide the fact that the most important part - the battery is Chinese... Most Tesla cars built in the US have batteries built in the giga factory in Nevada.

RE: Winterizing Residential Fridge

For ours it was easy but we left the fridge water filter in place. We just did a normal winterize and then used the front water dispenser to run water thru it till it was pink. Then tell the i emaker to come on until pink showed up. A little messy but fairly easy. Takes pretty much a jug of antifreeze by itself though because of the coiled line and the filter. A little more time consuming but meh. Not a big deal. Hope you get it worked out.

RE: 400 mile electric RV

It's Delta T temperatures that count. 72°F to freezing is 40 Drop it to 0°F is 70 Again to -20°F and it's 90°F And family size is critical for hot water heating, and keeping bedrooms at 70°F during the day not 45°F But thank you for your example. My pleasure Mex. I have to admit, you lost me ion the delta T discussion. But that’s probably because I think I’m celcius. Cheers and stay healthy.

RE: 400 mile electric RV

Electricity versus petroleum includes more than motor vehicles. There are so few examples of all electric homes outside California and perhaps Texas and Florida that obtaining sample data is frustrating. Do *any* of you know what it takes to HEAT a 2,000 sq foot home when the Delta T is one hundred degrees? People scream in agony when they receive a bill for cooling a home with 30 degrees Delta T. Drop it to 60T or 40T Add an electric stove, kitchen accessories, fast recovery 50 gallon hot water heater, and presto zingo, you are looking at eight to ten times the power consumption as a motor vehicle. The government is going to chop carbon emissions by the old classic way. Tax it. I live in a country that allows the 1st 75 kWh inexpensively. 76 to 150 kWh is double the price 151 to 300 kWh triple that. But wait there's more DATA ALTO CONSUMO allows for "X" total kWh to be consumed in a two-month period. Then the cost triples AGAIN and all lower tiers are eliminated for the next six months to a year. Fifty cents, US per kWh. Can't be done! Won't be done? The federal annual mileage tax proposal is a myth. So are Pennsylvania Turnpike Style toll booths and automatic chip readers for cars. Nahhhhhhhh, they'll NEVER tax out of state purchases... Unless you are a credentialed electrical engineer that worked with power generation and transmission projections, be very careful about your theories. Start with this --- Pencil up a work sheet with 150,000 BTU electric heat, a six burner stove, 50 gallon water heater--- Forget about the car. What size electrical service does an all electric house consume. Hint: In 1977 The Summit, an all electric, new, luxury subdivision in Lake Tahoe had a revolt by new owners. Their bills were averaging $700 month To control consumption during the 1972-1974 gasoline shortage, they simply rationed gasoline. Don't be foolish and start believing the USA will not go the way of its southern neighbor and price tier what they consider excessive consumption. New construction will utilize underground distribution construction, with conductor size amplified 33%. Steel cored aluminum power lines will exceed doubled 1000 MCM cable. The price of aluminum will blast off like copper did. My crystal ball is becoming clearer. Wait for the day, a $50 or $100 excise tax is passed for LPG and natural gas water heater sales. Not green, I'll have to settle for a mild TAN down here. Before you show outrage, my TOTAL energy averages 88 kWh monthly. And ten dollars per month in gasoline at $4.00 gallon. You're champing at the bit, but I'll blow your arguments first, all electric houses are new construction presently in California. But if you're young, brand-new slip-in electric heater replacements will appear. Electricians will be hired, and petroleum energy price increases will encourage you to not delay. I'm fortunate to have a single-digit years lifespan ahead. It will spare me from hearing all the weeping. Well, this is our friends totally electric home in BC Canada. Cold winters and very hot summers. Three vehicles, all electric. High efficiency heat pump and water heater and air conditioning. he has a modest sized solar system on the roof and is grid connected. Actually not bad. He has chosen not to go the Tesla power wall route...yet. Seems to work pretty good. He published these results on our discord group. He gave me permission to republish them. https://live.staticflickr.com/65535/51543434523_e92e90cc2c_c.jpg

RE: High profile tires on off road packages on trailers. hmmm

Why do they always feel the need to use a lug tread when they go to taller tires? For extra traction when you shift into 6-wheel-drive! LOL. :)

RE: 400 mile electric RV

If you do the back of napkin calculation replacing gasoline use per day in the USA with electric vehicles generating capacity will have to almost double. That doesn’t include diesel fuel for trucks, machines, and railways. The power grid now is over 50% fossil fueled so that will need to be fixed as well. Should be doable easy enough. I don't know. BC Hydro started working on this back in 2015 and have different calculations than yours. We are an EV only household. Typically 16000 km per year. Our power bill is more affected by air conditioning use than EV use. Our typical commute use is under 8 KW per day which is probably typical for many, at least around here. We are also a non solar house. Those with solar around us pretty much generate all the power they need themselves on an annual basis including charging their cars, heating their homes etc. Lots of variables. No simple answers but rather an aggregate of many. Here is a pub BC hydro put out back in 2016. There is other interesting info on their website. Tons of new EV fast chargers in this province from about half a dozen principal players like BC Hydro, Tesla, Petro Canada, Shell, Electrify Canada, FLO etc etc. The grid will adapt and change as needed. Its a thirty year transition. https://live.staticflickr.com/65535/49831525958_ba59f92eaf_c.jpg

RE: High profile tires on off road packages on trailers. hmmm

Tesla lol now some odd tear drop with basement air. So what is this mysterious SUV? It’s a T@B 400. The AC is one of those Norcold Cool Cats that mount in the basement. The T@B 400 doesn’t really have a basement but the AC is mounted under the booth seat. It uses an ALDE system for heat and hot water. We had a chance to get some measurements from our friends the other day. Think it’s going to be a good fit. Not a lot of outside storage but from what we can tell we won’t need it. Probably put a couple things in the SUV (or CUV as everybody seems to correct me on. I’m not sure I know the difference. :).

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Our model Y order has shifted from February to April and now they just removed the expected delivery date. Meh. It’ll get here. Still, seven month waiting list and no matter how much they keep ramping up production the waiting lines keep getting longer. Good problems to have for them...I suppose. Right now they are building at a rate of a little under 3000 cars per day. Speculation by some that to stop the waiting lists from getting any longer they need to build closer to 5000 a day and 7000 to get the lusts down to a reasonable amount. And that’s without going into any new major markets. Two new factories coming on line in the next 6 months will help. Normally people would switch to another brand with wait times like that, but right now the options are slim. That is changing though. GM, Ford and VW will all be ramping up production of middle class affordable EV’s in the next year. Things might look a lot different in a year. Tesla’s biggest mote is still the Supercharger network. Tesla May open the Supercharger network to some limited extent to other brands but right now it defines the brands. In our province the Supercharger network has doubled in a year (20 to over 40 by the new year). They are literally popping up in every little town on a variety of minor routes. Road trips for us have changed drastically in the last couple years. Anyway, all above JMHO.
