EV Myths (Cold Winter Range 1/2 rated nominal range) especially climbing mountains at freeway speeds!

On cold dark winter days when you need to run the cabin heater & AC to defrost the windows, your 100kWh latest new battery EV with 300mi of nominal range only gives 140mi of mountain pass climbing in sub-freezing temps while going 70-80 mph. 

Firstly, motor vehicles, powered by batteries recharged, gasoline, diesel, ethanol, methanol, propane, biofuels, synthetic fuels, cow farts or whatever, even nuclear, are not eco-friendly. Industrialization toxic to the biosphere as is human activity on the scale of 8 billion people at the same time. Back to splitting hairs about the differences between ICE refueling range & speed vs EV's with a flaky charging infrastructure that doesn't work during power outages. L1 charging on the go painfully slow. Even L2 way slower than gasoline refills. 

Solar PV be that Monocrystalline Silicon or even better CIGS, those are not eco-friendly to make or recycle. They are the product of carbon intensive heat intensive, chemical intensive, resource intensive, industrial processes & a supply chain that's mostly energized by conventional diesel in commercial trucks, or on heavy fuel oil burning container ships. 

Not emissions neutral, actually Solar PV & wind power turbines have huge manufacturing, distribution & installation emissions before they ever make DC to make AC to power your home or charge your BEV at home, or to charge your home LFP energy whole home battery UPS system, etc 

Anything industrial is eco-toxic. It's called globalization & we are in the middle of #4IR or t he forth industrial revolution. Say "widely applied artificial intelligence or information war" who ever controls the singularity & all information will own all future human societies, economies & governments.  

I can add 600 mi of gasoline range in less than 5 min in our 22 Corolla Hybrid. There are no EV's that charge that quickly widely available like Hybrid gasoline cars from Toyota. I am sure there is some custom super-capacitor EV that charges up in 15 seconds or something, but that's not a real-world car like the Prius which has sold in the 10+ million scale. 

Parking at the ski resort when its 22 degrees F outside & snowing & going skiing or snowboarding for 8 hours (1 hour for lunch, 1 hour for dinner) then you come back and your long-range EV that had 64% battery when you parked. Sadly, for you the 7kw battery heater ran all day to keep the batteries low in chassis above 40F so the lithium-ion battery pack can pick up some regen on your way back down the mountain pass to the city where you live & came from in the first place. But that leaves you with only 15% remaining charge, not nearly enough to get home, even if you capture enough regen to add 30mi of range (optimistic, probably less)(regen usually boosts BEV range in city stop & go by 10-15%.)

Meaning you have to stop & public charge, but there is a problem with the public charger or supercharger or LEVEL 3 charger, and no L2 charger working nearby because of power outages from a winter storm. You find a outlet used for block heaters & reluctantly plug in your EVSE level 1 slow trickle charger that only boosts your battery by 3-5 mi of range per hour of charging, meaning you have to camp in the car or nearby for 10+ hours to pick up enough charge to get home. 

 Its so dark & cold that your vehicle roof mounted solar PV panels did not add much charge, especially while buried under dozens of inches of snow that has covered the BEV while its parked at the ski resort. How do I know about this, 3 different Nissan LEAF's, starting with the 24 kWh model in 2013, then a 2015MY 30kWh version, then a 2019 40kWh SV. I traded all of them in for hybrid electric vehicles, A 2005 Toyota Prius II, 2010 Prius III, 2015 Honda CRz, and the latest a 22 Corolla Hybrid that gives over 50MPH & above 60MPG & even more than 70+ MPG on regular gas when mild or extreme hypermiling :) 

Public chargers are often not free either. And don't for a second think that electricity carbon free. The average kWh of electricity in the USA produces nearly 400 grams of carbon emissions. Oh, and to get that vehicle to you from Germany, Japan or somewhere else distant in Mexico, Canada or some US state not nearby, that means 30 tons of carbon emissions from the diesel trucks that got your 2-5 ton BEV to your local market where you purchased it. 

Did I mention that EV's shred tire tread away owing to their fun instant acceleration torque. Many Tesla BEV owners note having to change $2000 sets of tires in less than 10,000 mi and some in less than 5000 miles. Tesla models this or that are way more expensive to insure, way more expensive to repair, and that water based paint that rubs away more easily means that many Tesla owners spends several thousand dollars having their newer Tesla model whatever viny wrapped. 

A Hybrid Sienna, Tacoma, Tundra, Highlander, Rav4, Corolla or even the ever-popular Prius, now in 2023 with 196HP & e-AWD that still gives more than 50 MPG on real world regular unleaded gas in normal operating conditions when driven by regular people on average real world driving routes and on road trips. 

Try taking your new 100kWh BEV on a 8000-mile summer road trip like Meg & I did in her 2010 Prius III & enjoy many weeks of delays charging, when a few hours of gas station fill-ups did the trick for us. 

Also, we are not running out of gasoline for 300 years because of synthetic gasoline that's naturally unleaded & super clean burning like propane, made from natural gas, bio gas, or even coal gasification gases. Synthetic diesel & Jet fuel can be made with Shell GTL gas to liquids processes industrialized at the giga scale. 

In our Prius III or Corolla Hybrid, we can add 11 gallons of gasoline & go 500+ miles before the next fill up. With gas prices falling like home loan interest rates, we are seeing lower operating or fuel costs now as well. Regular gasoline peaked at $5.40/gal, but now under $4.50 a gallon & even less than $4 a gallon nearby at some stations. There are still millions of gas stations in America, they are not going away either. With Synthetic & Biofuels, there will be liquid fuel gas stations for hundreds of years. NH3 or Hydrogen & DME stations, along with more Propane stations, we will see these cleaner & sustainable fuels replace fossil fuels in the future. 

Hey, for local commuting, a BEV or battery electric vehicle is fantastic. I loved every Nissan LEAF that we owned. I only gave them up because I need more range, more freeway speed with Heat & AC on. I need to be able to road trip my car long distances and have a longer commute as a result of moving further from work to realize lower housing costs. 

EV Future Much Brighter

1MW or faster LEVEL 4 or LEVEL 5 pubic chargers that do 0-80 charging in 10 min or less
** requires industrial sub-station level power connection (not widely available) 

Better EV motors with axial flux & improved magnets, better power, lower mass, better regen. 

Better EV motor controller electronics with better EV motor control software, better efficiency.

Greatly enhanced regen with newer better batteries that can soak up current fast without damaging

Greatly improved battery chemistry that lasts longer, more cycles, more years, fade free, safety maximized & puncture & accidental crash safe without fire or smoke or flame. Way better energy density & improved volume density with packaging flexibility to fit more batteries in more places in the BEV. 

New flexible room temperature super-conductor wires with less resistance & better current flow improve all aspects of power movement through the BEV, battery pack, motor & controller. 

Better electronics with high power SiC silicon carbide chips. 

Gasoline piston & rotary & liquid piston & opposed piston generators will operate at one super-efficient clean burning RPM setting that reduces fuel consumption & lowers emissions while maximizing electrical power generation to energize the ranged extended EV traction motor & charge its traction battery pack. 

PHEV or plug-in hybrid electric vehicles are just like this now. The Rav4 Prim has almost 500HP & the fastest accelerating RAV4. Its also full time AWD traction master with the best grip in all weather conditions. The downside is that it's also the heaviest & destroys tires the fastest as a result.
