12m Solaris battery-electric bus with the PRIMOVE inductive charging system from Bombardier

Recently, Braunschweiger Verkehrs from Brunswick, Germany got the first 12m Solaris electric bus, equipped with Bombardier PRIMOVE inductive charging.

All together, in the project “EMIL” (Elektromobilität mittels induktiver Ladung, electric mobility via inductive charging), five such buses (12m and 18m long) will operate on a 12 km line.

Very high is the power of this wireless charging system- up to 200 kW.  Buses will not be fully charged at once at bus stops, but instead several times throughout the whole day at different locations (see video). Battery pack capacity is 60 kWh.

Interesting is the receiver, which has some kind of undercarriage pantograph-like mechanism to reduce the distance to the ground charging pad.

The drivetrain of the bus comes from Vossloh Kiepe and puts out power of 180 kW (240 kW in 18m version).

"On March 27, 2014 a 12 m long battery bus from Solaris with electrical traction and on-board power supply equipment from Vossloh Kiepe went into passenger service with the Braunschweiger Verkehrs-AG as the first of altogether five buses. For the first time ever the modular system from Vossloh Kiepe has been combined with the inductive charging system Primove from Bombardier."
