If you have a 100 kWh battery, that is 14 hours to charge at 7 kW.  Max overnight charge is therefore limited at that level.  No point having a larger battery than that. ... Still no point in a larger battery capacity because you can't charge that between one day working and the next day working.

That may be true if you are road warrior doing a job that requires 300 to 400 miles per day. But the majority of the population aren't, and only drive 20 to 30 miles per day (which is me). I still want a large family car that can take 4 to 5 people and all their luggage, and I want to be able to drive anywhere in the UK for my holidays. So I have a car that can do up to 300 miles in one trip, with an 80kWh battery but that doesn't mean that I need to completely charge it overnight. If, on the remote possibility that I needed to do that mileage on consecutive days I could always stop at a charger that will stuff in 135 miles of range in 15 minutes.

We seem to be in agreement

300 miles on 80 kWh is 3.75 miles / kWh so my target of 4 miles / kWh is realistic:

3 to 4 miles / kWh, so 300 to 400 mile range so the vast majority of daily demands are met.  Actually, the 4 miles / kWh is an achievable target and I think realistic to achieve.

We also agree that a battery larger than about 100 kWh is beyond requirement.

No we don't agree on that. The requirement is an individual thing. For a second car doing the school run every day, an old 24kWh Leaf would be fine.

The issue is with the 'need' to fully charge the battery overnight. If I have a 50kWh battery, and a charger that will just do that overnight, then all is fine. If I buy an EV with double that battery size - 100kWh - then nothing changes, I can still recharge the same amount overnight (which relates to the miles I've driven) I just have a bigger reserve. If I buy an EV with a 200kWh battery (assuming it was an option on my car), then the same applies - I can still charge the same overnight, but I now have a much, much bigger reserve.

The reserve will get topped up eventually and all will be fine.

To come back to my original response: the size of the battery isn't limited by the amount you can charge overnight.

I would like to be able to do 250 miles in the cold and wet at 75mph.  The 77kwh ID4 will do about 170 in these conditions.

You could try driving within the speed limit. You might just make it then. 3+ miles/kWh shouldn't that hard to achieve, these days.

Welcome to the party Australia.

EV sales triple in 2021 which seems to reflect a lot of news I see that demand for BEV's exist, but supply is low. And not just Tesla, the article matches comments I've heard* that MG's and Hyundai's are really in demand, just need more supply.

*A newish Youtube channel 'Electric Viking' based in Australia gives lots of info especially from Asia and Oceania, and  the host Sam definitely has a liking for the excellent products from Hyundai.

New electric vehicle sales triple in Australia with Tesla outstripping other makers

The number of new electric vehicles in Australia has tripled after years of lagging sales, off the back of incentives introduced by state governments to support their uptake.

Australia recorded 24,078 EV sales in 2021, a significant increase from the 6,900 sold in 2020, which means electric cars now make up 2.39% of the new car market.

“We’ve been waiting for quite a few years to hit the 1% mark, so to skip that and go straight to 2% is a big deal,” Jafari said.

“We’ve been waiting for quite a few years to hit the 1% mark, so to skip that and go straight to 2% is a big deal,” Jafari said.

It has been reported that Tesla gave the wrong figures to the Electric Vehicle Council.

The Guardian has issued an amendment to that report:

• This article was amended on 1 February 2022. An earlier version, based on information supplied by the Electric Vehicle Council and Tesla, said there were 24,078 EVs in total sold last year, including 15,054 Tesla Model 3s, but this included sales for both 2020 and 2021. As a result the proportion of new cars sold that are electric has been amended from 2.39% to 1.95%.

Tailgating small lorries at 70 it will do 225 miles 100% to 0% at 4 degrees with no heating on.

The Skoda Enyaq has an option for a heat pump to keep the batteries at optimum temperature in cold conditions. I presume the ID4 has the same option, as it is built on a common platform.

How salary sacrifice is giving electric vehicles a lift

Long associated with pensions and shielding long-term savings from the tax man, salary sacrifice schemes have been springing up as a way of driving electric vehicles (EVs). Similar to the cycle to work scheme, it lets workers pay for around just as half the monthly payment, using their salary before tax is deducted.

That drop in costs helped the Tesla Model 3 become the second-most popular car bought in Britain last year, propelled by leasing companies snapping them up.

The benefit also grows with the wealth of an individual. with the very best deals reserved for those earning between £100,000 and £123,000. They can reap discounts of 60pc because of reductions in their personal tax allowance.

Mini and Maxi.

Not sure if the electric Nissan Micra has been mentioned, but one is planned, built by Renault, and I'm sure would be very well received.

Nissan Teases All-Electric Micra Successor For Europe

Designed by the Japanese automaker, the model will be based on the Renault Nissan Mitsubishi Alliance's new CMF B-EV platform shared with the future Renault 5 EV. Both vehicles will be built at Renault ElectriCity in northern France, a complex of three plants (Douai, Maubeuge, and Ruitz) repurposed to form Europe's largest EV production facility.

And at the other end of the size scale, we have another leccy loco, that can run for upto 24hrs on a charge doing rail yard switch work.

Union Pacific buys ten more all-electric locomotives, this time from Caterpillar Inc.’s Progress Rail, investing over $100 million in total

Progress Rail’s EMD Joule is a 118.1 ton electric locomotive switcher with an available battery capacity between 1.9-2.4 MWh, with additional options available. It has a nominal power of up to 3,000 HP, and a run time of up to 24 hours on a single charge, depending on utilization. Like the Wabtec FLXDrive, the EMD Joule battery recovers energy reserves through dynamic braking.
