That will never happen. Manufacturers have the electric car users by the short and curlys. The battery will last about eight years and they will price them such that it is uneconomic to replace them so the car will have to be scrapped. They will never relinquish such a piece of planned obsolescence. Also how does the user know how much charge is in the replacement battery?GHT wrote: ↑Tue Jul 07, 2020 6:50 amYou're probably right, but the speed that technology goes at these days, it will only be a matter of time. Back in 1986 I saw my first ever mobile phone, this fellow had, what looked like a small satchel slung over his shoulder, the satchel was for housing the battery, the phone was akin to a landline handset on top of the battery. It wasn't that I thought it wouldn't catch on, it just seemed like a lot of faff to be the first to have a must have. Texting back then was still to come.suffolkpete wrote: ↑Tue Jul 07, 2020 6:27 amYou'll probably find that with that sort of power the batteries last for about 20 miles and take three days to rechargeThe reason that electric is so powerful is because it does away with oscillation. A piston oscillates, meaning that it stop/starts as it goes up and down in the bore. If you can devise a way of just rotating, like a jet engine, like an electric motor or even like a sewing machine, you will have a much faster, more efficient power plant.That's got more to do with the power consumption of the mobile than the size of the battery. To run a car like that at full power for thirty minutes would require a battery of nearly 1 kWh.
To fully recharge it from a domestic supply at 7kW, the most allowed, would take 139 hoursThe new Vauxhall Corsa exceeds 200 miles between recharges and now Tesla have produced the long range battery giving their car 400 miles between charges. It's just my speculation of course, but it's not beyond the realms of fantasy to say that there might come a day where you pull into a garage and instead of putting fifty quid's worth of unleaded in, you simply swap out your batteries for re-charged ones, pay your money and drive off.gas turbine cars never caught on
