BY ALEX LAUER @ALEXLAUER After a winter storm left hundreds of motorists stranded on Interstate 95 in Virginia earlier this month, many for over 24 hours, we were left with plenty of questions. What went wrong on a governmental level that led to this? How could similar traffic shutdowns be avoided in the future? What should we be carrying in our cars in case of an emergency like this?
The most perplexing question of the bunch was a hypothetical one: what would have happened if all of these cars — stuck on icy roads in the snow in temperatures that dropped down to the teens — were electric? Well, it was posed as a hypothetical question, but most of the people who asked it perceived it as a rhetorical one; the implication was that if I-95 was full of EVs, the outcome would have been a catastrophe of dead batteries, stalled vehicles and frozen occupants.
It’s easy to make an argument against electric cars in extreme cases like these, partially because the technology is so new and thus easily misunderstood, and partially because, as we have previously discussed, EVs do indeed fare worse in freezing temperatures than in warmer weather (as do internal combustion engine cars). But to see whether there was an argument to be made in defense of our supposed electrified future, I did something a little more difficult: I idled in an electric car for 12 hours to see what would happen.

The citizens.
Do some homework 9n how much gasoline is burned and replace that with megawatts.
“LOL. Do you sleep with it in a bottle by your warm body?”
Havey ou seen any early aviation films from Alaska? They did that. :)
Read and profit.
For the unlikely event, you might read this linked article:
...However the electricity source of EVs has to be considered when determining overall vehicle efficiency, and while powering an EV via coal is not as environmentally friendly as using electricity from renewables, it doesn’t mean coal-fired charged EVs are not as efficient as ICE vehicles.
An EV motor is around 85 - 90 per cent efficient when converting coal-fired energy to power. It’s estimated that technological improvements will see emissions from combustion engines falling by about 1.9 per cent a year through to 2040, according to Bloomberg, while EV emissions are anticipated to fall between 3 per cent and 10 per cent annually.“EVs convert over 77 per cent of the electrical energy from the grid to power at the wheels. Conventional gasoline vehicles only convert about 12 per cent – 30 per cent of the energy stored in gasoline to power at the wheels,” according to the US Department of Energy[iii].The difficulty for ICE vehicles is by providing driving flexibility; they sacrifice thermodynamic efficiency. As The Driven points out, “petrol and diesel cars are very inefficient in converting the energy in their tanks into motion at the wheel ... over 60 per cent of the energy is wasted as heat.”
I wonder if heating the battery compartment would be any advantage ?
You can count on the socialist government to issue an edict directing power companies to give preferential treatment to those who have EV’s, leaving us internal combustion cave people in the dark.
—”I wonder if heating the battery compartment would be any advantage ?”
Tesla does it.
Tesla Adds Battery Pre-Heating To Improve Efficiency In Cold Climates
There is no way I would drive anything not gas or diesel up north, and I an sure the test put the least possible strain on the vehicle, but I was still impressed.
—”I bet you were all in on the metric system too when “they” tried to force that down our throats.”
Please tell us about the deficiencies of the metric system?
And contrast with the joys of a collection of feet, hogsheads, horsepower...
Scientific instruments also switched to metric. We should have changed everything except possibly where some sports wanted to keep their records.
Face the facts, the public rejected the metric system, and they are rejecting EV’s. If EV’s were the bees knees everyone would be clamoring to purchase one. Instead, we have the government giving our money to charlatans such as Musk to further their agenda, and they have tools such as you spouting the party line.
Keep your C-note, you seem more of a hick than I.
LOL, that was my first thought also.
Ridiculous
Most cars won’t make for 3 days. My Volvo S60 which is GDI and normally gets well over 30 mpg has a 70 liter tank that’s 18.5 gallons for you yanks. I have a fulltime Bluetooth OBDII transceiver on the OBDII port it feeds a dedicated tablet on the dash with over 100 metrics in real time with one HZ updates. One of those metrics is fuel burn directly from each injector there are 5 so the software sums them up on a one second basis to give grams per second accurate to the gram quantity. That said I idled after earning the engine up to operating temp with a 5 mile drive around the golf course down the road with the heater on full blast and the blower on high with outside temps last night of 18 degrees F it was holding steady at 0.354 gallons per hour in petrol consumption I also was running my XM radio and had my phone pluged into the charge port. Typical set up for running around. 18.5 gallons would last for just over 52 hours of idling at that consumption rate. During the summer with the AC on high it’s 0.46 gallons per hour to idle and I do idle a lot in it F being hot in Texas summers petrol is cheap compared to across the pond in the USA you pay for a gallon what a liter costs across the pond I will idle all day at those prices.
Why not just diesel and gasoline. Ethanol lowers MPB, and takes 50% more regular fuel to manufacture and grow the crop, than it creates in product. It also takes millions of gallons of water for the crops and making of the alcohol.
—” the public rejected the metric system”
Then why is it that all vehicle manufacturers excepting HD, and they use a mix, are all metric?
How did that happen with metric being rejected and all?
Appears to be well accepted; yes there are always a few ill-informed malcontents.
Pls tell us about your great enjoyment with the Imperial system? What is it that gives you this great pleasure?
You should go with Whitworth, it’s the future; for you.
But many will.
You are referring to manufacturers accepting metric, not the public.
Reading comprehension is a skill. Try it sometime instead of flying off the handle and insulting other posters to promote your point of view.
What is the age of the batteries? I suspect the car is brand new.
