Has anybody tried something silly like carrying 5 fully charged batteries in their trunk, and every time your about to run out of energy, you stop, switch to a new battery, and keep going till you’ve gone through all 5?(Then you stop somewhere and recharge them all).
Last time I checked on EVs, it was 2010, when they could only do 10 to 30 miles per battery, and I remember somebody did this with their own EV converted from a gas car to travel long distance, lol.
Right now, I’m carless, and depend on myself using a bicycle to travel anywhere(I have a 50 mile a day range, lol.) I’m injured right now so I can’t ride, so probably why I started thinking about EVs after all these years.

A Tesla Model Y battery weighs 1,700 lbs. Think what lugging along five of them would be like.
That’s a plot twist I didn’t see coming, last time I saw an EV battery in the early 2010s(from a custom car) it was still at a weight that a person could pick up with both hands. (That’s all I remember, and why somebody was able to rotate battery packs for long drives.)
Well, a few things have changed since then. Your idea isn’t in practice, but there ARE things called EREVs. Basically, imagine a motorcycle motor in an EV. The motors are electric, the battery powers the car, they just get a little tiny motor to charge the battery and extend the range
Your thing is basically the space issue is a nutshell; you need more batteries for more range but each battery adds weight, which requires more batteries etc
That actually sounds like the best possible setup for a car, the best of both worlds of electric and combustion engines.
When I made this post, I didn’t realize EV battery sizes had increased exponentially, I would have assumed the size stayed the same and capacity increased x10 by now.
huh? No
The battery in a Model Y is 1,836 lbs and is the entire dimension of the passenger compartment (below the floor).
You can’t just “carry 5 full charged batteries”. That would be almost 10k pounds of battery. Not even close to reasonable.
I’m still living in the past(2010) when people made their own EVs out of gas cars and batteries could be picked up by a single human. What a plot twist that batteries increased in size to increase battery life instead of increasing in capacity while staying a small size.
I’m wondering what other “advancements” have been made in the EV field since then.
Well, as revealed in this very thread, somebody did in fact make their own DIY workaround to this problem. lol
No. There might some day be a market for range extender batteries but these are probably going to be for Towing.
In a single use situation an Air-Zinc or Air-Aluminum battery might work. These are single use.
