Fully Charged in Just 6 Minutes – Groundbreaking Technique Could Revolutionize EV Charging
(scitechdaily.com)
This is a most excellent place for technology news and articles.
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.
