We’ve only got a stated range out of this (252km/157mi) but there are a lot of factors where this could do well. Sodium batteries should be cheaper, so it’d be great if that translated to the final sale price. Depending on charge times and where you live, this could be a perfectly practical vehicle. If it doesn’t degrade like lithium batteries, then that’d be even better. Might make for a great secondary vehicle (or everyday driver, depending).
That’s a perfect range for me. If it’s relatively cheap and charges reasonably well in the winter, I’ll buy it.
We currently have two cars:
- hybrid sedan - only used for commute (50mi round trip) and around-town trips
- minivan - mostly used for long trips, or when my spouse needs to take the kids somewhere while I’m at work
A lot of my neighbors have a similar setup because either one person doesn’t work or works at home, but they often need to use both cars simultaneously. If it’s priced well, it’ll sell well.
The main problem with existing EVs are that they either have far too little range (e.g. original Leaf w/ 70 miles range), or are way too expensive because they try to get too much range (200+ mile range). That higher range is kind of necessary because of degradation, whereas if the battery were cheaper to replace, more people would be willing to buy something with lower range and replace the battery after a few years.
The economics of an undegrading car battery are interesting.
It’s looking like these batteries will allow electric cars to be comparable to an ICE car in terms of price and cheaper to run.
So people will buy them as it makes sense. Then run the car until it falls apart then they will have a very large battery effectively for free. Does that get placed in a new car? Converted into home storage? Grid storage? Cheaply recycled?
I’m expecting to see dual battery EVs in the not too distant future. A Sodium battery for the primary that gets the most charges and discharges which can be easy and cheaper to replace. Beside that a Lithium battery which would only be drawn from after the Sodium battery was exhausted. This way if you’re doing shallow discharges for your “around town” driving then charging at night, and deep discharges for longer road trips where the energy density of Lithium shines.
I’m still dreaming of seeing EVs with flexible battery space, which users can fill according to their needs.
Like a car comes with space for 10x 10 kWh slots.
If 20 kWh serve your usual needs, the other spaces remain empty.
And if you plan longer trips and don’t want to recharge each 100 miles, you put in additional batteries. Those batteries don’t need to be owned, but can be rented.
Ideally there are lots of battery rental stations, where you can get charged batteries and instead of recharging the batteries in the EV, the rent’n’swap stations recharge them.
During (EV) wise low use times, these stations can provide a buffer to the energy grid.
…one can dream…
I’ve seen a video with some electric mopeds that had very easily removable batteries. Like you just pop it out and exchange it at a gas-station equivalent.
It’d be ideal if we could settle on a few sizes - kind of like how we have AA, AAA, C, D, etc. batteries. One can be for such mopeds, one larger for cars and some smaller ones to fill various otherwise empty spaces in a car.
So if your battery goes bad or just want to change its tech you can do that.
For normal city driving you carge the car at home. If you go on a trip make a few stops for charging. If you’re really in a rush, you can always pay a premium for swapping your drained battery for a prefilled one at a gas station equivalent.
To me this seems like the ideal solution for EVs and I wonder what facts make it unrealistic.
Idk about renting, sounds like ass.
A core charge would make more sense, like swapping propane tanks you get a discount for having the empty core with you.
You know, putting and removing batteries would be a very tedious task and I really doubt that many owners will bother with it.
Lithium batteries dont like being stored fully charged they will degrade over time.
This is a solved problem. Most EVs won’t let you charge it to the actual 100% level or discharge it to 0.
So only charge it to 80% and pretend 80% is 100%, like iPhones do. Why is that a concern?
