I think the 120kWh is probably the largest figure for an EV battery, which I think is on a Mercedes-Benz EQS? Even then, it’s only 107.8kWh usable. It uses this to get an EPA (lower than WLTP so trying to get a more extreme scenario) of 277 miles. I don’t think many people travel that much in a single day, so if we assume a more conservative 70 miles (to make the division easier) you only need to top it up perhaps 25-30kWh per night, which doesn’t need 120kW charging.
At 6 hours, you’re looking at 5kW t charge, which is close enough to your 4.8kW figure.
It would be bizarre for everyone to need to recharge a 100kWh battery every night. This is part of the difficulty of shifting to EVs, the mindset has to change. It’s not about empty to full anymore, it’s about top-up charging.
There’s a LOT of vans on our estate, they’re doing miles each day not the daily commute. Plus most houses have 2 cars. The maths start to get crazy.
I’d love to see a profile of the typical mileage done…
Had a ride in a Tesla Plaid recently. 2 serous launches down a dual carriageway and the range halfed.
Is that particularly surprising? I would imagine the range also involves averaging over the journey thus far, and launches are full power. It’s not too dissimilar to how the Veyron famously could drink its entire tank in 12 minutes flat. That’s 100L of fuel too, which is far beyond the average fuel tank size.
TL;DR for you: much power requires much energy

Although it would eat it’s tires in 10, which is possibly of greater concern.

I mean, the same concerns are present in EVs, right? Except in bigger levels in some ways due to the weight of the batteries.
As the @cynicaloldgit says, the best way forward is a reduction in the car population as much as is feasible. I’m guessing it will need a combination of societal shift to more mass transportation options, but also a shift towards more renting rather than owning.

My home town, +/- 18k population.
This doesn’t include 10k students, or (according to Google) 1m tourist room nights per year.
Only a handful of charging points.
Woefully insufficient.
That screams to me a massive opportunity, if I’m being honest. But again, grid and production concerns are relevant. I wonder what the maths works out to be in terms of optimal number of charging points, assuming that all cars there are EVs.
It looks like my wife’s old car can be resurrected by the local Volkswagen wrangler. I suggested that we would look for a replacement car in the new year anyway.
We did go to a local car supermarket place yesterday and it confirmed my view that all modern cars are shite. This probably wasn’t helped by the wind, sleet and freezing temperatures.
Naturally, in the inclement weather, the first thing that caught her eye was a cabriolet…

Not sure if this would get a flaming but I’ve wondered if one method of moving people from cars to public transport would be to cut performance. I mean you can buy a car that can make a mockery of speed limits anywhere now.
You still need to address public transport availability and links etc. but the car is the easy option. Maybe it shouldnt be?
Just saturday morning, shit weather thoughts.

A simple park and ride scheme usually helps. When I lived in Scotland I would never willingly drive into Glasgow or Edinburgh if I could park up and get the train in.
Similarly in Liverpool, I usually just buy a Savaway and forget the car.
If public transport isn’t piss poor and expensive then people will use it.

Isn’t there a thing about how they’re cheaper at this time of year? I think it’s something to do with consumer psychology and how people don’t shop for cabriolets in winter.

Well the one we saw was already sold, but yes. They are a fairweather purchase. I suspect that they are also mainly bought as second cars.
Can anyone explain this stereotype to me? I never understood it… Is it just because so many of them do drive convertibles, or is there a deeper joke?
