Since the batteries are on a loop in the battery replacement station, they don't need fast chargers or special high amperage, high voltage grid connections ... regular chargers are built into the box that hold the batteries in the loop. Relying on charging at regular household voltage and amperage also simplifies the charging at home.

The main innovation in that system was in the commercial side, in selling miles/month like a mobile phone company sells minutes per month.

I don't know if this Chinese company has special fast charging technology, but in many batteries, heavy reliance on fast charging reduces battery life.
