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.
i = current in amperes
V = voltage
P = i times V (watts)
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.
Wow! That’s hotter than the ‘third rail’ on a subway.
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.
Living in Florida, I see EVs all over the place every day, mostly Teslas, but Rivians, and others..............
It does...............
Independent now, but still owned by China and Volvo.
Cables must be red hot!..................

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 just checked FWIW:
Washington DC Metrorail runs 660kW at 750VDC. Arithmetic says WMATA trains are pulling 880Amps.
This charging station is delivering approximately half the current of a WMATA train car, at roughly the same voltage. That’s some serious power. Switching it is going to be interesting. Cooling the battery and the charger is also going to be interesting.
I’m impressed with how far they’ve come with batteries and battery charging. I’m also impressed with the ease, safety, and simplicity of delivering a whole lot of kWHr through a gasoline hose ...
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.
