NOT really Solid State:
IM calls the battery pack in question “Lightyear”. It’s not a strictly zero-fluid solid-state chemistry, instead utilizing a semi-solid layout that includes solid material suspended in a liquid electrolyte.
The 900-V Lightyear pack has a capacity of 130 kWh for a total range estimated to exceed 1,000 km (620 miles). Just as impressively, it’s said to be capable of adding 400 km (249 miles) of range in just 12 minutes when wired up to a properly quick ultra-fast charger.
No details on what the chemicals are in the pack, or HOW big of an ultra-fast charger it takes to reach that 12 minute number. It’s all in the details with EVs.

This is easy to calculate.
You never drain a pack more than 10%’so the rates range is over a state of charge window from 100% to 10% or 90% of pack capacity it’s called the effective capacity of the pack. 113kWh effective over 620 miles is 188 watt hours per mile.
249 miles needs 46.8 kWh @ 188wh/mi add in 10% for DC/DC losses you need 51.48 kWh DC from the charger. Over twelve minutes that’s 0.2 of an hour so you need 5 times 51.48= 257.4kw this is V3 fast DC rates at 900V that’s 285amps the NACS plug has a 500amp standard and has been tested and certified up to 900amps the CCS standard used in the rest of the world is rates to 500kw with a cert to 1000kw before you move to a megacharger standard that tops out at 3,000kw with the plugs coming from the maritime industry where 10 megawatts is used for navy ships and cargo ships on shore power.
My solar panels made 139 KwH today so if I wanted to fill er up I guess I could :)
