Nothing like sneaking a little pejorative propaganda into your supposedly "impartial" news article. Nice work there, Paul Ridden.
P = i*V
Numbers for "i" and "V"? Article didn't say ...
THought polestar was discontinued/sold/disowned by Volvo.
Fabulous driving experience, though.
What size charging cable would you need to carry 375 amps, and also be insulated against 800 volts?
But I have a problem with: But those needing to make longer daily trips are going to be plugged in more often. Ummm...no. If you daily use DC fast charging you're wearing out your battery. Use it only for every now and then long trips (or unusual long day of running over 200 miles in errands around town).
No one should think about getting an EV as one of their cars unless you intend to drive it with mostly home charged (slow charged) miles. And that needs to be at least 12K miles per year for the gas savings to offset other costs that come with an EV (at least that's my humble opinion based on the past year of gas and power prices in Alabama).
Then there are other requirements like, don't get one if you plan to use it for a lot of snowy winter driving, or drive on trips through charging deserts, or drive a lot of long trips without your wife (assuming she's the one who wants to stop every 200 miles no matter what kind of car you drive LOL). Don't get an EV unless it's one of two cars (i.e. you're married) so the other car can be the gas car for the times you might take a trip that an EV is bad for. For us, it's the gas pickup since I every now and then need a pickup for pickup chores and it requires a load with many more miles than an EV pickup is good for. With those parameters, our EV works well for us, driving it 15K to 16K miles per year with home charged miles in the warm southeast.
Now test it again on Christmas Eve when the temperature is below zero and let’s hear the results.
Just like every other rechargeable battery....eventually it will begin to degrade in distance and charge capacity.
How many charges until that begins?
How much is a new battery + installation labor cost?
Somebody correct me if I’m wrong but I thought speed charging a rechargeable battery shortens the lifespan.
Use the sun or wind or waterfalls, or it’s just pretending.
My 30 year old Honda will go 400 miles with a 5 minute fill up.
I have an electric golf cart. Amazingly boring. I can’t imagine driving around in a car with an electric motor.
I like V8 engines. Exciting to operate and maintain.
Filling up a touring sedan with 20 gallons 87 octane takes less time than 10 minutes— and gives a full tank range in the most efficient models with cruise control of 500 miles. Game over. EV is no way to to— and, the batteries degrade on storage, and they will still catch fire. No comparison.
And their testing revealed what about the effects of fast charging on battery life?
Handling such large current flows is dangerous. Branched medium weight hydrocarbons are still the way to go, both for convenience and safety.
None of which changes the fact that our electrical infrastructure is too marginal to support a significant portion of our populace switching from dinosaur-powered automobiles to battery-only EVs.
Pretty much everything in the sourcing, processing and delivery of fossil fuels to the retail distribution points is powered by still more fossil fuels and puts ZERO additional load on the electric power grid. Everything to do with operation of BOEVs puts still more load on the grid, which is finite in capacity and in some regions already overtaxed.
I can fill my RAM 1500 in five minutes and drive 500 miles. My cost per mile when considering cost of vehicle and maintenance etc. is less than an electric car. When an electrical truck can do this at the same cost to me without a government subsidy I will buy one. I am familiar with chemistry, energy fuel density, cost analysis, and how much those damn batteries weigh.
When Air Force One takes off from Washinton DC and flies non stop to Tokyo at full gross weight with only battery power I will buy an electric vehicle. It will not happen.
The laws of thermodynamics aren’t just good ideas, they are laws.
Firstly, where is all of that power going to come from?
Secondly, SO FAR, batteries and capacitors with a very high charge rate also have a very high self discharge rate. Wonder how this one specs out.
