3 minutes with this charger gives an EV how much range?

Answer: 100 kilometers (about 62 miles).

BMW’s and Porsche’s new electric vehicle charger is so powerful that only a specially modified car can use it at full capacity without frying its battery. The two car makers teamed up to build the charger, which can put batteries at an 80 percent charge in 15 minutes. That’s half the time of Tesla’s popular supercharger.

In order to avoid cooking the system, the car’s battery and the charging cables themselves have to be actively cooled. Therefore, the charger that was just installed in the state of Bavaria for charging BMW’s i3 will only deliver 50 of its full 450 kW. It will give 150 kW to the iX3, slotted for release in 2020.
