Read today about a concept bus line starting June 15th in my home town of Gothenburg. Some interesting info:
(Volvo used to be a Swedish company based in Gothenburg. It's now a Chinese company but they still have a factory in Gothenburg and a lot of design and development there)
Energy storage system:
Lithium-Ion battery (Water cooled)
Voltage 600 V
Capacity 4 x 19 kWh (comes to 76 kWh accordin to my math)
Charge:
Fast Charge time 6 min/10 km range
Fast Charge power up to 300 kW
Maintenance charging (400 VAC) 4 h/day
Electrical motorOutput, max (kW) 155
Torque (Nm) 400

In addition to regen braking, "Recharging also takes place via the mains electricity grid at the two end stops, at Sven Hultins plats (Chalmers) and Teknikgatan (Lindholmen). Recharging takes about six minutes and is more than sufficient for the entire route."
They will have 10 buses on this line, 7 hybrids and 3 fully electric ones.
It seems charging happens from above:
