A big tank in a fueled personal vehicle makes sense because you don't want to have to stop and fill up every day. However, big battery in an EV doesn't really make sense since it should be plugged in every day when you get home for a few hours.
Except some people actually travel. Who wants to stop and charge every 100 miles?
An easy way to get around this would be replaceable batteries. Like how mobile phones used to work.
Running low? Pop to the nearest charging station and swap your battery for a fully charged one. Or bring a spare. I've seen a video of it being done for scooters, don't see why it can't be scaled up for cars
Been thinking about that since EV were just getting started. Of course it means you'd need to create new standards, get all the manufacturers and gas stations to use it, etc. But I really don't see why it couldn't work that way, park the car over the system, empty battery comes off and full battery goes in, pay a monthly subscription or something.
Then take mass transit or get a car that runs on fuel. Having all this extra battery mass everywhere is just bad all around.
I don't think most people appreciate this fact.
And the impact it will have to our roads that are already poorly maintained.
It seems we can only build infrastructure but can't fix it.
We can barely build and deploy fast charging infrastructure. It just doesn't make sense trying to use BEVs for long distance travel.
Exactly. I think a small, light and cheap battery plus a gas range extender for long trips makes way more sense than carrying around 2000 pounds of battery that only gets fully used once a year.
At the very least, vehicle batteries and fuel tanks should be limited to prevent drivers from driving too long without a break. It's kind of reckless to put 600 mile battery in a personal vehicle.
