The other company that makes batteries that charge this fast, BYD, also makes appropriate chargers, which use a somewhat higher voltage, of 1000 V. Those chargers can provide up to 1000 A.

Yes, I am aware that BYD has demonstrated a 1000 kW charging system. In their case it's literally the headline (1) or subheading in other articles (2) Which is very much in contrast with this article not mentioning these numbers at all. It's odd. Are you saying that you know that this CATL charger has the same specs despite this? That was my question, really. 1) "BYD Unveils ... Megawatt Flash Charging " https://www.…

I do not know more than is said in this press release, but I assume that they have coordinated to use identical charger specs, otherwise both would lose. It is said that there already are hundreds of such fast chargers installed, so at this point it would not make sense to try to install other incompatible chargers or to make cars incompatible with the existing fast chargers.

I assume that the chargers are more or less compatible with the older chargers, but they must be able to negotiate a higher charging voltage and higher maximum charging currents.

When either the vehicle or the charger does not support the higher voltages and currents, they should fall back to an older and slower charging mode.

If anything, Nio battery swap stations would allow car users to swap to newer types of battery as they become available. I say this knowing Nio is one of CATL's most important partners[1]. [1] https://eletric-vehicles.com/catl/catl-calls-nio-an-irreplac...

In a well designed urban environment where cars have space for 2-3 modular batteries with swapping capabilities, I see no reason why taxis etc. need to carry battery payload > 150 km of range needed for local use, which would mean better fuel efficiency as well. Battery swapping done right is integral to this

Sorry, but I giggled at this. A well designed urban environment would have no cars.

Cars,those urban monstrosities the vehicles that weigh over 25 times their payload and take up 20 times the space on the roads.

Should I adjust the figures for American sizes?

Should I also add that they are engineered to travel at speeds over 120 mph and usually ply the trade environments where 30 mph is a dangerous speed?

5 minute swap is not needed for this.

Well, if it degrades to 90% after three years, and let’s extrapolate to 81% after another two to three years, then a battery swap in 5 minutes might be reasonable to do instead of charging once every three to five years or so. I guess it depends on the quality and retained capacity on the batteries being swapped in.

The poor grid. The US added basically 0% extra transmission capacity last year. ... Now your local charging station will require a nuclear plant to keep up with ~1MW per car.

For this sort of fast charging you need the charging station itself to have a large pool of batteries to buffer the energy from the grid and to push it at very high power to cars. Probably still requires a good size connection to the grid. I think this is unavoidable for any sort of decent charging station from now on, anyway but does require significant investment in infrastructure.

To add, the technology for stationary batteries (lithium phosphate) is cheaper, because you're no longer constrained by density/size.

The whole fast charge thing is mostly marketing to convert people from "gas car mindset" into getting an EV. The reality of the situation is that most people who buy an EV will use fast charging only a few times a year. The majority will be charging overnight to recuperate their daily use, which amounts to drawing What would be a strain though is large ultra fast charging stations along major travel corridors. But I'…

Wait. You're missing something. Charging was what stopped me from getting an EV when I was a renter. In a world where I can recharge in 7 to 10 minutes, it becomes a lot more feasible for a renter to get an EV without at home charging capabilities. A renter can just pull up to a recharging station. Wait 7 to 10 minutes or (maybe 5 if they don't mind a half charge) and be off.

Renters shouldn't get EVs if they cannot charge at home.

Which sucks, but the majority of people (2/3) don't rent.

the life span stat with the current battery tech is mostly useless for a normal car. 300 mile range most people will need to top up 2 times a week 100 times a year 1000 times in 10 years. The battery degradation is not that bad in the first place.

First, with range decreasing, number of charge cycles per mile, and therefore rate of wear, will increase. Second, average age of car on the road is above 10 years in most countries; and those that drive old cars definitely do not have €26,500* spare to swap their EV's battery for a new one. *That's what Audi charges here for e-tron 50 battery replacement, which are already starting to fail for many owners

> First, with range decreasing, number of charge cycles per mile, and therefore rate of wear, will increase.

By 10% over 10 years, assuming the worst case of nothing but ultra-fast charging. This seems minor.

Old cheaper cars could be 10% less convenient to use for very long trips. This should not shock anyone.

Rather than an expensive battery swap, sell it on at a lower price to someone who doesn't need 100% range.

but you/stuff still needs to go from a to b. taxis (or individual self driving pods) should however be the future of public transport.

They simply lack the required space density.
