Still, a problem that persists is the process of recharging.
Let's assume that in a few years we will have a battery pack that will be as light and as compact as a petrol tank and will be able to store 150 kWh, which is almost thrice of what the Tesla Roadster's battery pack can cope with. Great for the car and its range, but in order to recharge that battery in a reasonable amount of time, you need to push in enormous currents. Let's assume it takes 15 minutes, which probably would be acceptable for the average driver. 150,000 Wh in 15 minutes is only possible with industry standard power supplies, which still doesn't solve the problem of cooling the battery during the process and providing a plug and a cable that are easy to use as well as safe and that can cope with the necessary currents.
A battery swap station in combination with better batteries would probably be the best solution, but that would need standardized cars as well as changing stations and thus a completely new infrastructure. But since we need that anyway whichever way we go, we probably should just see where the future takes us.
Batteries have been advancing for decades too, and this new lithium advancement has made a huge impact on it. The physics behind it aren't promising though. You simply can't fill up a 400 mile battery in 2 minutes like you can a tank of gas.
Okay, lets assume, like the vast majority of consumers (in the UK at least), that you do less than 100 miles a day, which seems to be par for the course for new EVs.
Lets assume that your 100 miles is done at a (high) average of 50mph. You'll therefore spend about two hours in the car.
Couldn't you charge your car in the other 22 hours of the day that you aren't using it?
Robert Llewellyn, of Red Dwarf and Scrapheap Challenge fame, is currently running a Mitsubishi i-Miev. Although he's clearly talking a little tongue in cheek, he makes a good point in this video:
How long does an EV take to charge? About five seconds, the combined time it takes you to plug it in and unplug it...
Now obviously, once you make a one-way journey that's longer than the car's range then you'd obviously want a much quicker recharge, but then I covered this earlier - the money you'd save over a year in "fuel" costs would easily be enough to hire a car several times over.
It's quite simple, if range is an issue, then don't buy an EV. But there are a lot of consumers for whom range really isn't an issue - and
that's who EVs make sense for.
Because our electricity supply will still be fossil fuel reliant for the forseeable future.
It's been mentioned several times over that the required emissions used to produce enough electricity for a single charge are far outweighed by those produced from a tank of petrol - not
least before you consider how much energy fuel takes to drill for, refine, transport etc...
Though I would love to know what kind of energy uses there are between the two methods. Say, doing 300 miles on a single charge, and how much electricity that uses, and how much fuel we need to make that electicity, compared with the, say 8-9 gallons of fuel that your typical road car would use to do 300 miles.
Again, such an equation would have to take into account how much energy has had to be used to create that 8-9 gallons of fuel, right from the point the crude oil leaves the ground.
Majority of cars on the road in the early 1900s were electric cars, that didn't work out.
Figures? I'd like to find out how you worked out that the "majority" were EVs. There was quite a mix actually, with EVs, petrol cars, steam cars...
The only reason they didn't work out is because petrol was incredibly cheap and companies like GM and Ford gave up.
Then we had the EV from GM, that didn't work out.
The EV was widely praised by everyone who drove it. It was good even on lead acid batteries - it would be
very good on modern Li-ions.
The only reason it didn't work out is because GM killed it and crushed all the evidence. I've no doubt that people would still be driving EV1s now if they hadn't all been destroyed.
Our nuclear, solar, wind, whatever power plant infrastructure CAN'T handle mass production of the batteries that will be needed for these cars.
First, you make the mistake of assuming that
all cars on the road would have to be EVs.
Secondly, you're forgetting that not only is electric energy over-produced, but that there is also vast spare capacity at night, for example. And night time is more than likely the time that everyone would be charging their EVs.
Unfortunately I can't find the video, but somewhere on youtube there's a vid of a guy in California who owns one of the old Toyota RAV4 EVs they produced a dozen years ago. He has solar panels on the roof of his house and even those are enough to power his entire home, his car, and still have enough excess energy to sell the power
back to the grid. That would of course be another option.
This tesla car going 300 miles while driven in a way no one would ever drive, is a joke. Drive it normally and the range gets cut by half. It's not that I love paying the Saudi's for their precious black gold, it's just that I'd have to pay 10x more for electricity if EV cars become the norm. No matter what becomes the standard, the consumer will get screwed by whatever companies we're going to rely on to provide that power. Until someone makes an engine that runs on rain water, I won't be happy.
Clearly. Some people are never happy unless things are being handed to them on a silver platter.
It's just as well really that companies like Tesla are at least
attempting to work with new technology rather than just giving up because they can't match a technology that's had over a century of constant development...
Let's assume that serious EVs have been under development for, I dunno ten years. That's probably a little under-estimating, but we've probably not had proper EVs on sale for too much longer than that.
The first motor car was released in 1882. I wonder if the EVs available now are roughly comparable with the petrol cars in 1892? If nobody bothered developing things then they'd have given up before the 1900s because horses were still so much quicker and easier to run.
