I think that idea died out after a couple of fires.

The extra protection to keep the batteries from getting punctured made swappable batteries non practical.

Not dead. Chinese auto maker NIO operates a chain of battery swap stations across China's highway network. However, only NIO owners can use the service.

As far as I can see the newest Hyundai Ioniq 5 (and maybe the tesla superchargers?) they recharge around 400km/250 miles in around 15 minutes. That is roughly 80% charge. As far as I understand they adivse that you don't charge up to 100% unless you do it slowly. The supercharging on the road is where you only fill up part of the battery, and then recharge more often....

The quoted 15 min charge time requires both a car and charger that can work with each other at 350kW. Most "Rapid" chargers are currently around 50kW.
Rapid charging speed is regularly quoted as being the time it takes to get from 10% to 80% charge.
It's mostly because that last 20% can take LONGER than the 10-80% charge.
