(later GEC-Alsthom N.V.) acquires Kiepe stake from ACEC S.A. 1973 Belgium’s ACEC S.A. takes over the family business. 1959 Establishment of the subsidiary Kiepe Bahn und Kran Electric Ges.mbH, Vienna. 1952 An order of 700 trolleybuses for Argentina (built by Daimler-Benz, MAN and Henschel) 1950/51 First orders received for complete traction equipment for trolleybus and tram. 1906 Theodor Kiepe establishes a "special workshop for the repair of electrical-arc lamps" Modern e-bus propulsion systems Why electrical traction? No energy loss at a standstill (e.g. at traffic lights) Electrical Motor = Electrical Generator Energy recovery when braking (start stop / downhill) Excellent acceleration (maximum momentum from standstill) High efficiency Minimum of energy consumption Powering e.g. two axles allows traction for longer vehicles higher passengers capacity Lowest possible noise level No exhaust / CO2 / particle emissions at the site Highest level of environmental friendly transport technology Modern e-bus propulsion systems Electro Bus concepts and their application Outside city Diesel bus Long distances between stops CNG bus High transport capacity / BRT Trolley bus Inner city Hybrid bus Short distance between bus stops Trolley bus Flat street profile Systems from Battery bus Low noise Vossloh ZERO Free of gases (exhaust & CO2) Fuel Cell bus Kiepe Trolley bus EMISSION 100% Electric Gradients Trolley bus bus Modern e-bus propulsion systems Trolley Bus Propulsion System System Integrator make it work reliable optimize 4 6 homologation 3 2 long term availability 1 6 5 1 Energy Management Controlling Units, Diagnostics 2 Brake Resistor 3 Power Electronics 4 Current Collector 5 Traction Motor 6 Auxiliary Power Unit (APU) 27 Modern e-bus propulsion systems e-Bus Variations: Serial Diesel Electric Hybrid 4 3 2 5 1 7 Electrical traction for 7 powering two axles zero emission mode 1 Energy Management Controlling Units, Diagnostics 2 Energy 3 Power 4 Brake 5 Main Power 6 Pantograph 7 Traction Storage Electronics Resistor Unit (MPU) Motor 29 Modern e-bus propulsion systems Advantages for two driven axles Applicable for articulated or double articulated buses Four wheels drive for better adhesive grip for: slippery conditions – e.g. for ice & snow streets with gradients strong accelerations (anti slip / ESP) strong deceleration / breaking more recuperation Back up in the unlikely event of a failure of one motor Weight of motor(s) is more even distributed in the vehicle (Higher load allowed on driven axle compared with non-driven axle) Return on investments due to cost savings Less wear of rubber tires No gear box needed (less costs, less maintenance, less noise, less vibrations) Less wear of axles & cardan shaft (avoiding maintenance costs of ca 10.000€ / axles) Customers who ordered once double traction (e.g. Geneva, Lausanne, Lucerne, Zurich) re-ordered double traction since then Rheinbahn Düsseldorf Modern e-bus propulsion systems Battery bus with overnight charging Braunschweig Modern e-bus propulsion systems Battery bus with inductive opportunity charging Project SEB Dresden Modern e-bus propulsion systems Battery bus with conductive opportunity charging Esslingen Modern e-bus propulsion systems Battery bus with In-Motion-Charging (IMC) IMC is also suitable for articulated and double articulated buses Project Rheinbahn Concepts Overnight charging Battery Bus Max. charging power: 90 kW Installed energy: 200 kWh Range: app. 110km Charging time per day: 2,5h night + 0,5 h during breaks 37 Fits in existing time schedule (Rheinbahn), charging during scheduled brakes Project Braunschweig Concepts Battery Bus inductive charging Max. charging power: 200 kW Installed energy: 60 kWh Average charging time per hour: 8min + coupling 38 Project SEB Dresden Concepts Battery Bus fast charging via pantograph www.edda-bus.de Max. charging power: 500 kW Installed energy: 86 kWh Average charging time per hour: 3min (+ coupling < 1sec) 39 3 min Usable in normal line operation !?
