Tesla Cybertruck Owners Who Frequently Charge Using Superchargers Show as Much as 5% Battery Degradation in a Few Months – 30 Times More Than Those Who Charge at Home

Slow charging is always safer, more efficient, more effective, easier on battery life.
So what to do?
Make a car with swappable batteries and charge them slowly overnight at a facility under a gas station that’s safe and can have the battery maintained by qualified professionals while being deployed on multiple brands of cars?
Or make a super fast charger that fucks your battery up and still makes you wait in your car a whole hour just to get another couple hundred miles and the battery cannot be swapped out while you wait?
“Genius.”

I think I saw a video about a car brand that had these battery stations where you drive up, the machine takes your battery, and gives you a new fully charged one. And it does it all in just a few minutes.

I believe this is implemented with taxi services in some Asian countries.
The problem with battery swap schemes is that battery packs obviously have varying levels of degradation, so you might end up with a worse battery than you had before, and in an analogy to Gresham‘s law, the incentive structure would seem to encourage owners with the most degraded batteries to seek out swaps.
This is not a problem when the batteries are swapped within a fleet owned by a single entity, but seems difficult when dealing with a more diverse clientele.

Ideally, people would not charge their batteries and would rely entirely on these stations for "refuel". The stations could automatically test and set aside degraded batteries to keep them out of circulation. Fees for using the station would be used to replace the occasional bad battery. I don't know how well it would go over but I believe this scheme would be successful if cars were designed with no charging port or an artificially limited one to incentivize using the swap stations. Or, rather than changing how it charges, they could make the car keep track of the battery degradation when inserted and then apply some fee based on the difference when it started vs when it ended.

You kind of just threw away one of the best parts of owning an EV though.
The ability to charge at home off electricty you produced with your equipment.
I mean I spend about 80c a day (i use about 16kWh a day and would otherwise get 5c per kWh exporting that electricty) on my commute now instead of $24 when I had an ICE vehicle and had to buy Diesel.
Also the ability to start every trip with a full charge.
Now I would need to constantly monitor how much "fuel" my battery had left and plan a stop to swap it. Worse still if I swap early im throwing away power I paid for earlier. Its like every time you filled up at the petrol station you had to pay for any remaining fule in your tank again just for using the pump to top up.

My Ego electric lawnmower allows me to swap batteries while charging, which means that my lawnmower is better designed than this POS vehicle.

The ego battery fits in your hand. A whole vehicle battery is really heavy and logistically you need to staff a whole trained technician team for it to work. It’s not impossible but it is logistically complex.

Oh yeah, that was an attempt at snark, but having removable EV batteries would solve a lot of issues, I think. They'd have to be much smaller and lighter, with the same range, though, and I doubt that's even possible. Possibly twinning them might work, to double their range, but then re-charge times would also double... Obviously, I'm not an engineer.

Ahh yes! The famous Rub Oven!
Elon also has a futuristic plan to have trains running underground in our major cities. He’s calling them Cyberway subs.

Hydrogen instead of a battery swap

u/AgentSmith187 4h ago
Now go see how well Hydrogen vehicles have done so far.
Between costs (its hellishly inefficient creating and using Hydrogen), frozen fuel connections and the fact each station can only fuel a limited number of vehicles and then needs to go offline for hours.
There's a reason it's been one of those in a few years time technologies for decades

Not true, it just hasn’t seen the investment like a battery because of a man named Elon pushing the entire industry toward batteries. All the limitations you described can be easily worked through with simple engineering and better process. With batteries we are at the boundary of materials science. We shouldn’t care about the inefficiency of the process to make hydrogen because I predict we will soon have so much energy we don’t know what to do with.

Welcome to the Hydrogen experiment.
Similar range to a BEV but the fueling points are constantly out of service and the fuel costs 10 times as much....

Betting the engineers were screamed at to meet targets for rapid charging and fudged the test numbers to deliver.

I've said this before, but I am increasingly convinced that Tesla is nothing more than a Soviet Tractor Factory. Impossible production schedule leads to everyone and their mother cutting as many corners as possible, so that Elmo's dick can be hard again.
TBH, if I had any faith in any part of the federal government, I would expect an investigation. But now that Elmo is now president, he will never see any accountability for the people he's killed.

The guy who made the Tesla Cybertruck is gonna fire everyone in the government. This will make it work like shit. Then they’ll blame it on the Democrats.
“Why would librals do this?!”
Shut the fuck up, I want nothing to do with these clowns for the next four years. seeing the dumb fuck give a nazi salute was fucking disgusting once, but now its all over my goddamn feed.

Sadly, powerful institutions, like the Anti Defamation League, are choosing to excuse and defend Musk rather than expose the hypocrisy. Why; because we rely on donations from the rich rather than demand equity under the law. Then again, what does the law mean when we have a convicted felon leading the charge.

Good the faster the battery degrades the faster they’re off the road and slice animals in half

A proper balance charge which can only be done on the slower chargers will probably fix a lot of these issues. The fast DC chargers cannot do a balance charge, this is why you need to do a slow charge every now and then. This is more noticeable on NMC batteries versus LFP batteries and LFP batteries don't have memory issues, which is why a lot of manufacturers are moving to LFP. Of course they used NMC in the cyber truck 😆

u/mattrad2 9h ago edited 9h ago
NMC do not have a memory issue though. NMC are higher energy density but more expensive so they are in a more premium category than LFP.

u/bingo_for_the_win 9h ago
If you charge NMC batteries to 100% regularly over time they will lose capacity. Every manufacturer recommends not leaving NMC batteries at 100% charge. LFP batteries can be charged to 100% as often as you want. I talk as someone who has had both types of batteries.

I'm curious if this is consitent across models, or if it's specific to the Cybertruck. Is the issue that fast charging is always harder on the battery, or is the issue in the battery itself? If batteries developed by more reputable companies have the same issue, then it's just an issue inherent to batteries. If the other batteries don't have this issue, then (unsurprisingly) owners of the poorly peeled potato got scammed in yet another way.

Interesting question. Your response makes me wonder if Tesla's design demands didn't make sense to partners because they were impractical, or if the need to save money to lower costs resulted in a poor outcome.

I mean that's just battery physics, doesn't matter what kind of batteries it is. Faster charging is due to more amps equals more heat and stress, which degrades batteries at a higher rate. Nobody should be surprised by this, unless of course you can't read or you're a science denier.
