Electric vehicles could fully recharge in 5 minutes with new cable design

My thoughts exactly. I charge drone batteries (with caution) and their "C" rating determines how fast you can charge them. It is a physical property of the cells. You need a beefier battery (higher "C") to charge at a higher speed, not a better charger. I need more details, as obviously drone batteries are clearly not EV batteries!

Charging a modern electric car is like charging many drone batteries at the same time with one power strip. It's not like charging one or two cells.

In this case, the "power strip" is passing 50kw and needs active cooling.

C rating still applies, charging at 1C is usually "fast" charging for most cells and that takes an hour, charging in 5 minutes is is 12C which is normally "bad", would need lots of active cooling.

50kw would take 2 hours on a 100kwh pack so it would only be 0.5C. To do it in 5 minutes would require 1.2 megawatts of charge rate.

Good thing lots of EVs have active cooling systems for their battery packs. It doesn't just extend range, it increases charging rates as well.
