How Oil Cooling Can Make EVs Even More Efficient
Like internal combustion engines, electric motors are designed to operate in a certain temperature range. There may be significant temperature variation in the different components, but the windings' temperature should be between 100°C and 150°C (212°F–302°F). As temperature increases, so does resistance in the windings. Thermal expansion can further decrease efficiency by modifying tolerances inside the motor, causing even higher temps and eventually permanent damage.
The kind of oil cooling Tovar is talking about for electric motors is similar to what we see on high-performance internal combustion engines. The oil can be circulated inside the motor through journals, and sprayed on components where journals aren’t practical.
Obi_Wan_GREENobi will be furious I’m supporting the use of fossil-fuel-derived fluids in EVs. Meanwhile, Darth_V8er is going to stroke his lightsaber as he teases the tree-huggin hypocrites still needing oil for their EVs.

Fun fact:
A wind turbine consumes how much hydraulic oil?
For lubrication, each wind turbine requires 80 gallons of oil, which is not vegetable oil but a PAO synthetic oil based on crude 12,000 gallons. That oil must be replaced once a year.

German Minister Threatens To Ban Weekend Driving Over Climate Law
April 13, 2024
Volker Wissing, Germany’s transport minister, has argued that if amendments to the country’s climate laws are not brought in soon, he could be required to impose Draconian measures, such as a driving ban on weekends.
He added that, without an amendment, the transport ministry would have to introduce “restrictive measures that are difficult to communicate to the population, such as comprehensive and indefinite driving bans on Saturdays and Sundays.”
In March, it was revealed that the transportation industry had failed to meet its legally binding emissions targets for 2023, reports The Local. Under law, Germany is bound to cut its emissions by 65 percent between 1990 and 2030, while meeting annual emissions targets.
Greenpeace also objected to Wissing’s rhetoric, claiming that he was turning his ministry’s failure to reduce emissions into political pressure.

In a totally unrelated story:
EV Sales Plunge 55% In Germany As Incentives Dry Up
Germany previously provided tax incentives to citizens purchasing electric vehicles. However, in December, the nation’s government abruptly decided to end the incentive program, and in the aftermath EV sales have cratered.
Compared to December 2023, sales of new electric vehicles were down 54.9 percent, while sales of plug-in hybrids were down 19.6 percent in the first month of 2024. On the other hand, the markets for vehicles with internal combustion engines were up more than 9 percent — +9.1 percent for gas, +9.5 percent for diesel.

Looks like you have to pay people to buy EV's in Germany too.

Just how do you get to 40,000 miles a year at 300 miles a charge? I spend many years in the 40,000 plus club as a manufactures representative and I can tell you the last thing a road warrior is going to screw with is a EV.

"fewer extreme weather events" What a moron! go ahead and prove that you green idiot.
For 14 years I was one of those 10-percenters. I looked in to EV starting in 2013. And your point is correct, even now it is difficult to find an EV with the daily range for a 175 - 200 mile commute on a single overnight charge fuel recovery. Add in winter range and good luck. EV do not make good long-distance commuters.

Happy TAX Day.

It's also appreciate all your tax payers that funded your EV rebate day.

I've never set foot in this thread before today, but it's incredibly hilarious to me that y'all sit here, day-in, day-out, screaming bolded taglines and EV memes at one another, like my parents and grandparents on Facebook.

Echo chamber, much? Don't you have some kids on your lawn to harass?

Regardless of what side someone falls on the EV spectrum, they'd both eternally cringe at the likes of most of you. For a bunch of boomers who eternally berate kids for being "terminally online", y'all never cease to amaze me with the scale of your internet data usage.

I took my reply down, because I didn't want to get in another alternate-logic discussion. But this plays to my point. Horses are much more difficult to maintain than cars (even early 19th century cars). They have a very complex diet and can easily die from improper nutrition.

For someone to say oats don't catch fire just shows more ignorance. And hay, if stored with too much moisture content, can self-ignite just like a lithium battery , though hay is easier to extinguish with water and takes less to do so.

But I digress.

KIA EV9 less energy efficient than Grand Highlander Hybrid

I saw a new KIA EV9 on the road last Friday. Looked cool. First one I've seen, but I ran the numbers and wasn't impressed. It's actually less energy efficient than a Grand Highlander Hybrid, and is only slightly more energy efficient than their own Telluride.

I did all of these calculations myself. You have to use real-world MPGe or range numbers, because claimed EV ranges especially on the highway are complete lies, on top of MPGe itself also being a lie. The Highlander Hybrid's 40% thermal efficiency (peak) is factored into its own MPG numbers, but the 40% overall efficiency of the power grid is not factored into MPGe for EV's? It's such BS, but that's on purpose and they hope you don't notice. C&D's real-world 75 mph highway range and MPGe numbers, which includes charging inefficiency and total energy put back into the battery, and not just energy consumed while driving, has been quite useful.

Anyways, good luck with an EV9. I mean if you're just shuttling larger numbers of people/gear/dogs or whatever locally and never really leave town I guess it could work, but why pay more for less capability? The reality is on a highway trip somewhere, you're not even making it to 240. Try more like 200-220 fully loaded with AC or heat running, and not really making it more than 2 hours without needing to find your next charging stop ASAP, where you'll only be able to charge back up to 80% quickly, and then get another 2 hours of range at best? We've legit gone 6 hours in my Suburban and emptied three-quarters of the tank before stopping for bathroom breaks and dog walks. Fill the 31.5 gallon tank in a few minutes and go another 600+ miles. I don't see how you'd ever get anywhere in an EV9. It would drive my entire family insane.

Creating a factor for weight is helpful and illustrating. As you can see on the far right, the EV9's powertrain is indeed more efficient at moving masses of vehicle around, but not more efficient enough to compensate for being 1400 lbs heavier than the Grand Highlanders. It ends up consuming more energy because of its weight, which is a similar story for many EV's vs. gas or hybrids, which is why they needed to create new ways to lie with the MPGe BS. So the battery weights are a huge issue. For reference, 20 gallons of gas weighs about 120 pounds, and will get you twice as far as a 1400 lb battery.

Interestingly, a fully loaded Suburban utilizing all of its space is consuming more energy, yes, but consumes less energy per unit of vehicle mass than either the Grand Highlander or the Telluride.

Pro tip. Take any MPGe figure and divide by 2.5 (or multiple by 0.4) to get the gas/hybrid MPG equivalent figure. I call this the "grid factor" for power grid efficiency, which must be factored in also to have a level playing field.

How are they more difficult? We have been riding, caring for, and living with horses for 5000 years. Horses are respected as individuals and often are honored for heroic deeds such as in war or policing. I already have stables near (or in) my home and grew up riding horses on a farm. The extent of my exposure to machinery is likely a tractor or factory where my dad works. It seems dumb to think I would use something that only works on paved roads, especially since I dont live in a major city. Besides, what if theres not a “gas station” within 20 miles?
