The photo at the top of the article shows a Mercedes FCEV bus, but the article is about a bus built by a company called "Tosa". Poor image choice.
The article states: "The fully electric buses roll into bus stops as they usually would, but then a contact on top of the bus rises to meet an overhead charger. Thirteen of 50 stops have the charging technology. The flash charger delivers up to 600 kilowatts for 15 seconds. At the bus depot, the chargers fill up the bus in three to five minutes using 200 kilowatts."
I am wondering how an EV battery can charge at a 600kW level, even if only for 15 seconds. I looked all over the abb.com website but could not find any technical details. Closed I got to an explanation was here

But that isn't an explanation of how it works.
