Battery swapping is a technology that could solve one key barrier for EV adoption: consumers’ range anxiety and the long waiting time for battery charging. Wouldn’t you feel more assured on a weekend trip if you knew you could stop at a swap station and replace depleted battery packs with fully charged ones in five minutes? But this isn’t easy to do, as Tesla and Better Place’s past failures. In China, however, battery swapping has been a reality for a couple of years. How did Chinese companies like Nio make it work with 2,300 swapping stations nationwide? What can companies outside China learn from the Chinese experience?
It’s not just that, its what happens if you get a battery from a guy named roger who said he knows what he’s doing and fucked with it?
Battery swapping sounds great, until you put it into a real world scenario.
There are already plenty of shady car mechanics named roger who can swindle you out there…
Yea, sure but that doesn’t effect me because I have the chance to know who’s working on my car, you don’t if you habe battery swapping going on.
Government regulation and standardization is the answer.
You know, like fossil fuels also are. For example fuelpumps have to be legally calibrated so that they measure accurately, and there are a myriad of quality standards and ratings regarding what 98 octane or 95 octane or diesel fuel or whatever can contain.
How does this solve the issue of roger fucking with his battery and then you ending up with it during a battery swap? You do realize how many states with counties have no inspections right?
The charger would have some inspection capability. Maybe not physical integrity of the casing but certainly the voltag and current outputs and connectivity of cells which could would correlate to health.
Ok, roger shows up dumps his shit battery or ticking time bomb and gets a free battery out of it. Do you plan on requiring everyone to show ID and get a face scan?
That is why they make you lease the battery. You cannot swap out your old battery, just the battery you are leasing. Your lease payments include the cost of them replacing batteries.
What stops people from messing with their leased batteries?
Quality control on batteries that go out to customers, and make the stations legally liable.
For example: I once pumped petrol in my diesel car due to human error by the gas station’s delivery company (they put petrol in the diesel tanks). They found out about the error as I was filling up and stopped me halfway, so luckily I had no engine damage, but they had to pay for the tow and to get my tank emptied.
Sounds more like a “your government is shit” problem than a “this scheme can’t work” problem.
As opposed to quality control from the manufacturer, once for the life of the vehicle, before you even buy, and with a long warranty?
…… that already exists?
Ah, so you’re wanting to transport tons and tons of batteries back to a centralized facility to be inspected and have testing done?
It’s not a gov problem, it’s a logistics issue.
No, that’s just something new you invented to shoot down the idea.
Batteries can have a tamperproof seal so that customers can’t easily mess with it, just like you normally don’t mess with the electricity, gas or water meter in your home. QC and charging can be done on site where you swap, and can mostly be automated. The only thing that needs to be transported back and forth regularly are defective and replacement batteries. Just like gas stations at the end of the day or week need to order replenishment for the fuel they’ve dispensed.
We already do this kind of swapping with other stuff as well: from crates with empty beer bottles and office water cooler bottles to refilling propane and butane bottles.
The lack of government oversight that you brought up, and which this was in reply to, is literally a government issue. Regulation and inspection works fine in most of the civilized world, the fact that it doesn’t in Backwater USA is no argument.
Fossil fuel distribution already is a huge logistics issue, we have to dig it up in the middle east, transport it in oil tankers, refine it at some central locations, then distribute it again with tanker trucks to millions of gas stations so that finally you can put it in your car and use it to drive somewhere, but somehow we have been making that work for over a century.
So each swap station is going to have batteries techs that know what the fuck they’re doing, checking on every battery that comes in?
What world do you live in? People fuck with their houses all the time, its why you get an inspection when you buy a home(even if most inspectors only find the shit on the surface).
Again so you’re going to have ever charge station have basically certified battery engineers that can check out battery systems that come in? Are you also planning on forcing the EV makers into standardized battery packs?
Cool, when is the last time you saw an empty beer bottle truck catch fire because roger fucked with his miller lite?
Ah so only in good ol EU do you guys not have car crashes and house fires because regulation has solved that shit.
Cool, whataboutism got it…the real problem you should be talking about is how quickly you can charge a battery and how long it’ll last on said charge…not let’s re-invent the wheel…
Gas gets to the gas station somehow. Obviously it isn’t the same as transporting batteries back and forth but it’s bad faith to say this is completely unprecedented logistics problem. I am under the impression that battery health could be screened at the swap facility and would require a small subset to be returned to a hub for additional inspection or repair.
Yea gas is a one way trip, and then it’s into the end customer. It’s not an unprecedented logistics problem, it’s just a logistics problem that ends up requiring a ton of more energy. Batteries need to be able to charge way quicker and hold a longer charge, that’s the problem that should be getting worked, not a how to transport battery packs around.
And that is being worked on. Billions of dollars has been going there. We have solid state batteries in the lab that can charge much faster and safer, and all sorts of companies promising to bring them to production in a couple of years. Do people really think we’re farther from that being reality than from building out an entirely new global infrastructure that will become obsolete before it’s completed?
The issue is we haven’t had real breakthroughs in battery tech since the 70s, we’ve gotten slightly better improvements but we’re still using the same base. We’ve had tons of promises in the lab but nothing has actually made it out. Hopefully there will be a breakthrough but so far there hasn’t been.
Truck still has to go somewhere. Obviously it’s lighter but it doesn’t blip out of existence. Amazon trucks to back to hub after delivery, FedEx, USPS. Both systems can advance independently and mutually.
I’m expecting drones to take a ton of the short space deliveries sooner than EV trucks.
To me, this is the biggest argument against battery swapping.
We have this huge industry for refining, storing, distributing, distributing ending gasoline that we can entirely dismantle with EVs. All that pollution: gone. All that wasted land: gone. All those unnecessary levels of profit-seeking: gone. Now you want to choose a technology that requires rebuilding all that, except two way? You want to force the new technology to conform to old infrastructure ideas?
How can we not prefer the alternative of “just plug it in wherever you are”? How can we not prefer the rare opportunity of simplifying something? How can we not forgo all those unnecessary profit seekers?
At the moment my two biggest fears against buying an EV is it catching fire in my garage and it dying after 5 years then having to buy a 30k battery. Once technology advances that doesn’t happen I will buy and I would love your plan. Why can’t this be a stop gap?
It already doesn’t happen.
Swappable batteries can’t be a stop gap because it would require a huge infrastructure buildout over many years that would become a lost investment, versus technology that’s already here and improving every year. Starting from scratch with swap stations, vehicle design, industry standards, vs hundreds of thousands of charging stations already deployed.
If you think chargers aren’t available enough or expanding enough, consider that they’re known technology, relatively cheap, installable by any electrician, using a national power infrastructure that already exists. Installing a level 2 charger at my house was equivalent to a new stove circuit. I mean I agree we need to speed up the buildout, but think how cheap and easy these are compared to developing an entire new infrastructure from scratch. How simple a ”plug” is compared to a robot that can handle a one ton battery. How long it took to standardize an effing plug, compared to standardizing entire battery packs. How can anyone think this would go faster?
With my EV I follow recommended practice to ensure longevity of the battery. I rarely charge it more than halfway as I don’t need to for my regular usage, and I avoid letting it run down entirely. Once you engage in battery swapping, where’s the incentive to take care of it well? After my first swap my brand new excellent condition battery is replaced by who knows what.
Exactly, this is the equivalent of tire swaps…my tires I take care of and rotate and replace when the tread is worn down, the hell do I want someone’s else batteries being in my car that could end up having a short lift or explode on me.
I can already hear a mile away lobbyist paid by the manufactures rubbing their hands arguing standardization “limits innovations” and “slow developments.”
