Fully Charged in Just 6 Minutes – Groundbreaking Technique Could Revolutionize EV Charging::Typically, it takes around 10 hours to charge an electric vehicle. Even with fast-charging techniques, you're still looking at a minimum of 30 minutes – and that's if there's an open spot at a charging station. If electric vehicles could charge as swiftly as we refill traditional gas vehicles, it wo

You're speaking with current lithium battery technology in mind. Supposedly, scientists in the article figured out a new technology that can be charged in 6 minutes. No word on whether it's still necessary to slow down at the end, or charging efficiency. Time will tell I guess

It's highly unlikely that they solve what is essentially a heat distribution problem with new battery materials. If you stick a huge number of cells in a giant cooling system then you can charge even lithium considerably faster than we do now for all of the 100%.

We are limited by the space, how good the battery pre condition charging is,maintenance schedule of the car and charging point.

My car has a separate fluid cooling system for ultra rapid charging that has its own maintenance schedule, if this system was bigger and didn't have to go a minimum of 12 months between changes then it could be charged for longer at higher speeds.

If my car had a bigger battery with more cells in a suitable arrangement then again I could charge faster for longer as the charge is spread out across the battery. However eventually you'll hit the point that you are only charging a few of the cells as the rest are full and you have to slow down or the battery will get too hot.

I just don't see them completely solving the heat problem, just improving the current percentages.
