Reply to comment by SSGSS_Bender in New Nio 500 kW ultra-fast Power Charger 3.0 can charge a car from 10-80% in only 12 minutes by Surur

This was my first question. We are offgrid on solar power for 15 years and now have a good lithium battery. Charge rate is very important and measured in hours not minutes for the very reason you state.

The misleading thing for most people is still thinking in gas terms. You don’t use a fast charger as often as you would a gas station.

I charge at home every night. My car gets almost 300 miles. Most people don’t drive anywhere near that daily. So the only time you need a fast charger is when you go on a road trip.

And using fast DC chargers that infrequently has a negative effect.

True enough if you can charge at home. I think the article referenced fast charging as an option for ppl who can’t charge at home. I would like to know how the occasional fast charging effects battery life, I know for our Lithium battery the charging cycles are stringently controlled so as to avoid quick charges. I imagine all these current issues will be resolved as the technology matures. I would like to consider an ev vehicle as our next car but we would have to add a significant amount of solar and if the car is not there during the 10 AM to 2PM sweet spot, then that causes other issues.
