What would be the difference in batteries like this?
Are you asking why some cars have a 50 mile range vs. 300 mile range on electric? It is all about battery capacity.
A Tesla has a huge amount of high end batteries. A Plug-In Prius, not so much. The Nissan Leaf has a fairly small amount of battery capacity compared to a Tesla or a Chevy Volt.

The Prius:
Not exactly sure what you mean since you seem to have left out a few key words. But I’m going to assume you mean why did the first electric cars have only a small range and newer EVs have much longer range. Is that correct?
Battery technology has vastly improved, and car makers have added more of them to the car. One of the first modern EVs, GM’s EV1, used lead acid batteries. They then switched to nickel-metal-hydride (NiMH) batteries which pretty much doubled the range. Modern Lithium-ion batteries pack even more power into a smaller package meaning less weight, longer range, and better acceleration. Modern EVs have learned a lot from previous generations and are in a state of steady improvement.

What I was really wondering about is, using the latest battery technology and a customer did not need more than 50 miles range what would the physical and cost differences in the battery be?
There are plug-in hybrids, that sounds more like what you’re looking for. Figure $5000 to $10000 cheaper.
Get an old Nissan Leaf and update the batteries for a 50 mile range and maybe the whole thing could be as low as $20,000.
But I don’t believe anyone is mass producing an electric only new car with a 50 mile range currently. So hard to say.
I guess I will put this question in the same thread as it is related. Let’s say we built cars with a dry weight of 500 or maybe 600# with a loaded weight not to exceed 1200#. Maximum speed was say 35 mph but special lanes for these cars were set at 25 mph. I would think this could be feasible and very tolerable for most local driving.
Those weights are very low. Keep in mind these numbers:
Teslas weigh 2,723 lbs to 5,390 lbs
Even a Smart car weighs around 1,550 pounds
Honey Badger, what you’re describing already exists! They’re called NEV (Neighborhood Electric Vehicle). Many municipalities have laws and accommodations for them.
The problem is that they’re not particularly cheap. Where they exist, they’re a 3rd vehicle for wealthy people to tool around in when the weather’s nice, or a vehicle to keep at a lake or beach house for traveling the grounds. They can’t compete on price with, say, a used Nissan Versa, while only providing a fraction of the utility.
It would be nice if vehicles like this could actually replace a gas car every once in a while instead of just existing alongside one, but communities would have to be built around them and gas would have to be much more expensive.
I figured they did exist; I just don’t hear much about them.
Sorry to fight the hypothetical, but that’s really swimming against the tide. Most studies cite “range anxiety” as the top reason buyers avoid electric cars, with too few charging stations right behind. That’s why Tesla always touts its models’ range.
Let’s turn the question around. How cheap would a gasoline powered car have to be for people to want it, if it only came with a four-gallon tank because most trips are less than 50 miles.
There is a huge difference, and the gasoline powered car would not be a good comparison. An electric vehicle can be plugged in and charged at many of the destinations while a gasoline vehicle requires going to a service station.
A brand new 2022 Nissan Leaf with a 40kWh battery is going to get about 100 miles on a charge in the winter. So that is new technology. If you require that you EV car be capable of being licensed to drive on the freeway as an actual car then around $20k is as cheap as it going to get. Anything less will likely not pass saftey or crash test standards. Going with a smaller battery will not save you much. Maybe get the car down to say $17k. Problem is not enough people want to buy an actual car like that to make it worth building. And the Leaf is a good example of how low you can go with newer technolgy.
Possibly yes but it very well may be that it just came in too early in the process of switching to these ultra-lights. It has to start somewhere.
You probably don’t hear much about them because there’s almost zero interest in cars that are too slow to take on the freeway and with with a range so short you can’t take them across a large metro area and back. But they’re the answer to your hypothetical.
Just because I’m fascinated with the probable scam nature of the entire enterprise, I’ll note that the ‘new vision’ of the Elio is something close to the OP’s intent - a cheap, light, all electric vehicle.
Which I believe as much as all the other claims of a company that was going to sell their cars with all ‘off-the-shelf’ parts in just a few years…nearly a decade ago.
You wouldn’t believe the number of lawsuits and cash flow issues they’re under based on the website, but here we go.
For the record, a reasonable review of the Elio timeline can be found here instead, which I think would dissuade anyone from investing time or energy in these yahoos.
This article could have inspired the op.
The argument is that most users are wanting to buy a car with their edge case in mind, leading to excessive use of the needed commodities compared to buying cars with batteries right sized for nearly all their actual driving needs.
LMFAO. Like the battery is the only cost in the car. Good quote @DSeid.
FWIW I think the argument is not less cost than less use of the various commodities that are in limited supply and for which rapidly increasing supply may have untoward environmental and geopolitical consequences: “supply side constraints”.
'Zactly.
Our collectively ability to build various ICE automobiles faster than customers want to buy them is not constrained (except by the recent chip shortages).
Our collective ability to build batteries is nowhere near as robust. If tomorrow everyone wanted a battery car, not an ICE, we’d be able to build everything except the batteries at the necessary scale once we retooled. Batteries themselves would definitely be the long pole in that hypothetical changeover tent. And in that scenario, “rationing” batteries by putting half as many in twice as many chassis might be a collectively smart move. At least until battery production caught up.
