What would we do without testing?
Testing by AAA has found that how far an electric vehicle can travel on one charge varies widely depending on the weather. Frigid temperatures can reduce that distance by 57%.
Imagine!

Maybe AA or D batteries might work better. On a serious note, well semi serious, what did they power those lunar vehicles with back in the Apollo days?
Sounds like the Fed could use electric vehicle range as an economic metric.
So using electrical energy from the battery to heat the interior and keep the windshield defrosted means you have less energy to propel the car through the denser cold air? Thank you, Captain Obvious.
What happens when one of these sparky things gets catastrophically rear-ended. What do the rescue personnel have to contend with in that event? There are some huge batteries hiding in the back of the vehicle and given that the consumer is supposed to call in the hazardous disposal people if they happen to break one of the curly 10 or 12 dollar lightbulbs in their homes, do the same hazardous disposal people have to attend a crash site prior to the fire department clean-up crew?
From Wiki:
Power was provided by two 36-volt silver-zinc potassium hydroxide non-rechargeable batteries with a capacity of 121 A·h each (a total of 242 A·h), translating into a range of 57 miles (92 km).[14] These were used to power the drive and steering motors and also a 36-volt utility outlet mounted on the front of the LRV to power the communications relay unit or the TV camera. LRV batteries and electronics were passively cooled, using change-of-phase wax thermal capacitor packages and reflective, upward-facing radiating surfaces. While driving, radiators were covered with mylar blankets to minimize dust accumulation. When stopped, the astronauts would open the blankets, and manually remove excess dust from the cooling surfaces with hand brushes.
After dealing with dozens of customers who own EVs I have learned that mileage is not important, smugness is all that matters. Simply being seen in your eco-mobile is the only metric that needs calculation. It’s all about feeling superior and nothing else. How else do you connect with a society of preening, self-absorbed ego maniacs? They can’t pull that off with me though, as they know that I know that their badge of sustainability is little more than a pile of toxic junk that needs constant, costly maintenance and frequent towing when it dies on the road.
Loss of battery power due to cold weather is not the only problem. According to the article:
“Heat also sliced the cars’ ranges but by not as much: The cars averaged 69 miles per full charge at 95 degrees, 33% less than in 75-degree weather.”
Gasp! Has the inevitable global warming they tell us about struck yet another blow against the electric car? This is what happens when you mess with Gaia.
My son lives in Florida, and they use electric golf carts for 95% of their transportation.
EVs work when you can get to work, schools, shopping, medical facilities, and entertainment venues. However, it’s just a regular golf cart, the kind that have been around since the 1950s.
the GOOD thing about electric cars is that they never run over the extension cord like they do with those electric lawn mowers:-))))
Duh! How many thousands did they spend figuring that out when all they had to do was ask any Saskatchewanite?
This is why leaving them stranded on the side of the road is what’s best for them, other motorists and the environment.
Perfect vehicle for those minus 35 mornings. Not!
I’ve been seeing a few new Teslas in Oakville and Toronto. I’ve seen -none- outside the city.
Its been cold, they probably can’t make it this far.
badump-tsh!
The central weakness of every battery powered device I have ever owned, was/is the battery. Henry Ford early n his career worked for Thomas Edison, who encouraged his experiments with gasoline engines because Edison never found a way to overcome the range limitations in his battery powered vehicle experiments.
I make good money catering to these twits, but I have been sorely tempted more than once to just push it into traffic when another Pious is passing. Puny engine screaming, struggling to haul 1500lbs of dead batteries at 140kph.
The rot at General Motors that led to 1.6M unsafe cars

It’s the industry as a whole
The cause must be similar to why my old 200 horse Case 2670 tractor won’t crank worth a shit when it’s 20 below. Someone should look into this temp vs battery crank-power relationship. It could be important!
N o 60
there is an old, and I mean old saying in the N A auto industry, engineered by bean counters. That’s why innovation was so slow. Ford realized in 2005 that they needed to change, and they started then, that is why they didn’t need a bail out. Shit, GM would still be pushing that venerable 3.8 if you let the bean counters have their way.
Well, as long as you get something out of it.
Was trying to find something like this but had to go to work.
Cold cranking amperes (CCA) is the amount of current a battery can provide at 0 °F (−18 °C). The rating is defined as the current a lead-acid battery at that temperature can deliver for 30 seconds and maintain at least 1.2 volts per cell (7.2 volts for a 12-volt battery). It is a more demanding test than those at higher temperatures. This is the most widely used cranking measurement for comparison purposes.

I find it funny that every one of these pieces of crap (Volt,
Leaf, Prius and Tesla S) have user forums that on the one hand
complain that the range of their cars is a fraction of what has
been promised, but are nevertheless satisfied with the same
piece of crap because the government subsidized the manufacturer,
bribed them $7,500 to buy them and is paying a good part of their
electric bill!
The same goes for bird shredders and solar power.
If your Chevy Volt cannot get any better mileage on the electric
motors than a 100+ year old Roberts electric car, you were bent
over and raped in the ass with a 60 grit sandpaper condom.
The Volt promised a 200+ MPG combined fuel efficiency. The
reality is that the Volt gets between 25-30 miles on the battery.
The combined efficiency is about 48 MPG, or less than 1/4 the
promise.
The Tesla S promised 400 miles on a charge with the 85 mwh battery, as well as the ability to change out the battery in
about 90 seconds. These were complete frauds! In a fair fight,
a 100 year old Mo. T would have beat a Tesla S over a course of 700+ miles. The Tesla had to charge for ten hours in two stops to
recharge.
These sparky cars have to stop every 4+ hours to recharge. A
truism is that it takes far more time to recharge an electric
battery than it takes to discharge one. The feces throwers
on this Blog will never understand that the last gallon of
gasoline will take a car as far as the first gallon.
This cannot be said of electric or hybrid cars, or solar or
or wind power! I am at my wits end because these morons
do not understand the concept of conservation of energy, momentum,
angular momentum or matter.
North of Rangoon is a bully, he attacks anyone who disagrees
with him because he is a poser, a dilettante. He has no
concept of mechanics, science or physics!
My oldest and dearest friend is a developmentally disabled kid
I met in 1975. He is a genius compared to North of………
Anybody who believes the green lie is to stupid to live!
Anyone who believes that Al Gore is a God or that Michael
Mann is a Saint is about to have a bad day!
Solar power is viable off grid, in small size applications, but almost nowhere else. If it displaces diesel fuel in remote communities, it can be an economical alternative for producing electricity. The two can balance well for duty cycles. However, the life-cycle economic parameters were developed from good quality N.American and European PV panels. The useful lifetime of Chinese solar has yet to be determined, but judging by the poor quality of most of the rest of their stuff, it’s not likely to be very good by comparison. Caveat Emptor
PV solar is as dirty or perhaps even dirtier than the oil sands. It’s not economically feasible to produce PV solar in North America or Europe. The labor costs are prohibitively expensive and the environmental regulations which keep our air, water and land from being heavily polluted don’t exist in Asia, so nearly all of the PV production is over there where they can pollute and keep their production costs low. The electricity to run their PV solar factories comes from dirty coal and the factories dump pollution into the environment. The same goes for their wind turbines.
Think they’re tied with Land Rover owners for preening, self-absorbed, a need for validation, & poor sense.
PV Solar is indeed a viable option where there is no electrical grid, as long as the demand is low. At the bunker complex I have a 120 watt array charging 36 volts worth of massive 2 volt lead/acid batteries. I also splashed out on a top of the line converter and control unit wired into the household wiring that can be switched to accept current from a semi-portable 12kw diesel genset. It cost a small fortune but there is no other way to get power, much like northern communities, but my demand is minuscule in comparison and only during the summer months @ 49 degrees North. But it works very well if one is diligent. I doubt solar is much more than an expensive novelty in situations where the demand greater than a few megawatts. Again the problem is in storing and/or converting power effectively and efficiently. With appropriate emission scrubber systems a diesel power-plant is the only sensible option for even small communities. Running the power-plant on natural gas is becoming an even better option, assuming the eco-nuts fail in their quest to drives us all back into caves.
And KVB, you are correct. Land/Range Rovers have a very short service life and high maintenance cost to compliment the extortionate purchase price which makes them nothing more than an gaudy and flamboyant symbol of wealth and privilege.
I’m always bemused when some vehicle manufacturer brags about their model XYZ, saying that 90% of them are still on the road.
My first thought: The rest of them made it home.
PV panels are only viable about 6 hours a day. Even if you
pump their overhead output into lead acid batteries, and use
an inverter, you run into another problem:
It takes longer to charge batteries than it takes to discharge
them. So, if you like having electricity less than 12 hours
a day, solar is for you!
I would recommend lead acid batteries because LiOn will burn
your house down if overloaded or charged too fast.
Solar energy is a fools errand!
