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

I'm sick of reading phones and cars charging in a matter of minutes for the past decade.

Don't worry about it too much. These sorts of articles focus on battery tech, but the ultimate limiting factor is the ability of the plug to supply power.

A Tesla Model 3 has a 75kwh battery. Let's say it's at 20% charge. That's 60kwh to get it full (assuming 100% charge efficiency). It would take 600kw to charge that in 6 minutes.

The SAE J1772 plug is only rated to go up to 400kw on DC level 2, and you'd be hard pressed to find a charger that does it. I couldn't find info on Tesla's plug, but since it's about the same size, it's likely around the same. Tesla's superchargers are themselves only going up to 250kw.

It would take yet another plug standard, and chargers that can actually handle such a load. Oh, and upgrading the electrical network to handle such a beast in widespread use.

Most of which is pointless, anyway. EVs are best handled by giving them a little charge wherever they're parked. For road trips, unless you're the type to pee in a bottle and eat sandwiches you prepared ahead of time, about 300mi range with existing charge rates is sufficient.

Didn't think of this with this point of view
