In the article they state they charged it at 1C, which is 1 hour from 0% to fully charged (200kw for a 200kwh battery). Who knows what the final numbers will be

In the article they state they charged it at 1C, which is 1 hour from 0% to fully charged (200kw for a 200kwh battery). Who knows what the final numbers will be, but very promising if true.
- pkulak 5y agoYeah, but maybe that was one of the 100 the battery can take before it's at 70% life. There are just so many sliders with a battery, and they all effect each other. Getting them all up at once is the grail.
- Wistar 5y agoNice analogy, the "sliders."
- karamanolev 5y ago1C is usually not 1hr from empty to fully charged, because of CC-CV charging. Most Li based chemistries charge at 1C until a certain threshold (when the needed voltage for 1C charging reaches a maximum predetermined level, usually the target max cell level, e.g. 4.2V). After that, you charge at constant voltage until you reach full charge. If the battery is significantly oversized, i.e. it treats 85% charge as 100% for the user, then 1C might be possible from 0 to 100%, but usually it's not.
