3 Münster Electric Bus Project Project SEB E-ÖPNV ( 1 bus) 500 kw Charging, 4-6 Minutes 85,6 kwh Li-Ionen battery (3 x 621,6V / 46 AH) VDL Citea-Electric length: 12,00 mtr (full capacity, 80 passengers, 43 seats) height: 3,02 (no problems with bridges or garages) Project ZeEUS (Integration of a bus line, 4 buses ) ( new: 4 x 62,6 Li-Titanat battery) Ziehl-Abbegg Achse Folien-Nr. 3 Name Name

4 Opportunity Charging versus Overnight Charging avoide high prices take advantage of low prices Folien-Nr. 4 Eckhard Schläfke

5 Power Prices (stock prices) Folien-Nr. 5 Name Name

6 Ultra Fast Charging Station Depot Münster Power Transformer Bus Shelter + = Add a connector on the bus shelter and install a plug-in connector on the bus roof = Charging Type Münster : A smart and cheap way to charge a bus we are on You Tube Elektrobus Münster Folien-Nr. 6 Name Name

7 Solar power system and storage battery at the depot Folien-Nr. 7 Eckhard Schläfke

8 Nachladung/Opportunity Charging Charging along the busline, high costs, sophisticated city planning, less flexibility Charging only at the terminus stations, by using existing bus shelters less participation in decision-making, high flexibilty inductive or pantograph Conductive, automatically plug-in High charging rates are unavoidable to reduce turnroundtimes Sinhuber, Rogge, Rohlfs, Klawikowski 8

9 The big question: Turnround times versus Infrastructure cost 3-5 Minutes 8-15 Minutes Driver tasks - Cleaning bus/station -Feedbacks office/garage (complaints, accidents, shifts etc) -E-training/E-instructions diesel Cost-Effective, but problems in cases of delays > low reliability, dissatisfies customers and drivers electric Optimized for fast charging, possibilities for extra heating (winter) and extra air conditioning (summer) to reduce energy consumption from the battery, conductive charging up to 500 kw within 4-6 Minutes for km possible, no charging along the bus line > more flexibility for the daily operation The lesson is clear: expended turnroundtimes lead to cheaper infrastructure costs and cheaper buses due to the smaller battery Folien-Nr. 9 Name Name
