10-80% in 3 minutes 44 seconds (not-so-plain old LFP)

The 10-35% in one minute is also pretty impressive, in case you need a quick "spark and dash" to get to the destination. Other sources mentioned 280Wh/kg, which is in the same ballpark as quoted for advanced NMC (Cobalt-containing & more expensive) batteries.

Semi-related: the Donut Labs saga seems to be Theranosing.

I think we ll start seeing models being launched in UK with 600kw+ charging speeds in 2027. I imagine cars like the upcoming i3 / C class will be outgunned pretty quickly in terms of range added in 10 mins .

I see Ionity has started installation work for some HYC1000 chargers and BYD also rolling out their flash charging stations.

I expect even on a 800v / 400kw charging station these new BYD / CATL batteries will be able to top up more quickly than the new ix3 / i3, as they should be able to hold the max charge for longer.

Seams majorly confusing. We start we a battery that can be charged super fast, then move onto battery swapping and then another battery that can also be charged super fast. Why do we need all these development if the Shenxing battery is so good?

This is all very well but it can only apply to public charging stations. Home charging is where the economy of EVs lies and that will remain limited by the power limitations of domestic supplies.

Time isn't a factor for most with regards to home charging though of course. Even with EV tariffs limiting cheap charging to 7 hours. that's still 150-200 miles a night for most EV's on a standard 7kW charger.

The real limitation with home charging isn't speed, it's accessibility.

What’s confusing? The made it perfectly clear the battery swapping is designed for extreme temperature situations.

There's usually a difference, but charging with IONITY (with passport Power) in Finland costs less than the basic household electricity rate in Geneva. I think even with the dual rate (about 0.19€/kWh nighttime), you might just break even if you account for AC charging losses.

Policies, technical developments and competition should narrow the gap between home and public charging (eventually).

100%

No one gives a toss how long it takes to charge once you're at home sipping wine or snoring. It takes exactly 10 seconds to charge at home: 5 seconds to plug in, 5 seconds to unplug in the morning.

Quite so.

The first genuine lab sample solid state cells have barely improved on li-ion energy density anyway. The potential for solid state to massively increase energy density is real, but as with li-ion, it'll take a lot of time post initial commercial readiness to actually approach that potential. There's no chance that solid state EV's are going to arrive and instantly make existing EV's worthless.


Also... if you have an EV then it's existing range and packaging obviously works, and even when there is an improvement, it doesn't mean that everyone suddenly 'needs more'.
