As we all know, electric cars are quite far from replacing the internal combustion engine.
The 2 major problems seem to be:
1. Time taken to charge from flat.
2. Range from a single charge.

One idea that occurred to me the other day could solve problem one. A standardised removable battery pack.

This way instead of waiting to charge you pull into a filling station and just change the battery. Obviously this would require lifting equipment/docking station or some such device to load and unload the batteries and would incur a charge of say £50. Obviously you can still charge these batteries at home if you wish.

What other ideas does PH have for improving the viability of electric cars? Specifically, those that could be implemented with current tech? A 1000 mile range that charges in 1 minute is still a long way off

What about buses? They have known routes and therefore known required ranges. They are much bigger so can house bigger batteries. A bus depot can easily incorporate a battery change out station. Most don't run at night so there's time to charge.

Thoughts?

Anxiety over battery longevity is often repeated. Maybe have a battery health status as some laptops do.

Attitude and expectations.

I think people are making a mistake by thinking of them as a direct replacement for a normal car. They are more limited, but if you are willing to charge overnight, and don't do over 100 miles a day, they are capable of replacing many cars.

The battery replacement thing was tried, but failed. Eventually I think someone will make it work.

This already exists for Tesla in the States I think:

I could easily get away with an electric car for 99% of the miles I do. For the moment it's all about the range for me as we have family a 500 mile round trip away, treble the range and I'd consider one.

Just watched that video after someone mentioned it on the Tesla thread. That's exactly what I was imagining. With standardised batteries they could all have a shelf life and be recycled. Not sure of the exact chemistry behind batteries losing performance over time but would be interesting to know if its a reversible process so batteries could be rejuvinated

Re: Buses, since they follow a route it would be easier to run wires along the route, thereby avoiding the need for batteries:

Replace the electric motor with a small combustion engine fueled by hydrogen?
The production & storage of hydrogen just isn't going to be viable.

The Tesla Model S will do over 200 miles on a charge. I do more than that about once per decade, so the range I need is already here.

Beyond that a range extender is the best option, you only need enough about 10hp to keep a car at a constant speed. That can be done with a very small efficent ICE. Personally of you need long range though, you should stick to ICE.

Not convinced, have a look at the reviews on youtube, or a review from one of our own....

Range is easy to fix; you just have to be happy with the increase vehicle cost and reduced mile per kWh for the extra mass that you may only need once ever 100 trips. This is why most EVs offer in the region of 90 miles range - purely as a compromise rather than an actual limit.

Given the possible saving that can be made with an EV, I think many would still be better off by renting a car for the occasional long trip.

My Scalectrix cars always went better if the track was really clean and the wire braid was straight and tidy.
I would wipe the track with meths and keep the braid neat by trimming it a little with nail scissors.

That, my friends, is the future...

I don't think the battery swap idea will work for cars, but it's pretty commonplace for forklifts.

I did some work for a (huge) distribution centre, and they had a battery recharge/swap area. At the end of a shift the fork would just pull in and swap the battery for a fully charged one.

The idea of just using electric as a KERS type booster combined with a smaller, more efficient IC engine is the most appealing tbh.

Maybe the biggest improvement would be to explain to all the right-on left wing media types who fall for the whole electric car thing, in words of one syllable, that it's not about how the car is powered, it's the root source of the power that matters.
Electricity production in the UK is still a filthy dirty basic process that involves little more than setting fire to stuff.
Internal combustion does the same thing but on site, lectric cars have it done elsewhere and fed to them in a cable. The start of it all still involves digging/drilling stuff out of the ground.
The tree huggers also need to look at through-life costs and impact and see how the production of batteries using rare metals that can't be recycled compares to traditional manufacturing methods using base materials.

I'd rather Drax chucked out filth than the stationary corridors of cars and busses I walk past and work near every day, TBH. Electronics is a horrible dirty business too, but that's a wider problem than just cars and should be of interest to more than just "tree huggers".

swapping batterys sounds like a poor idea , who would want to take thier week old battery in and swap with one out of a high miler

Idea one

A two foot tall sticker on the windscreen of all electric cars saying

" DRIVE OVER 100 MILES DAY REGULARLY?

BUY A DIESEL YOU TARD!!!!!!!!!!!!"


Idea Two

Fit a standard 30 minute fast charger in all motorway service stations so the off occasion someone takes an electric car on a long journey they can recharge


Idea Three

Make bacon rolls in motorway service stations enjoyable so when you are there waiting the 30 minutes a fast charge takes you aren't too bored


Idea Four

Anyone who blocks an electric charge point with their normal car gets shot in the head for being an inconsiderate arse



Two of these ideas are impossible in the UK
