Operation modes:

d) Full electric bus network

c) Operation in a part of the

bus network

b) Operation on a (special / single)

bus line

a) Operational trials

(redundant vehicles)

Trials and test projects

(e.g. FC buses in HH, Pinneberg,

tests in Bonn and Bremen)

Agenda

■ Ideal case: Minimizing operational efforts by a one-by-one replacement

of an diesel by an electric bus

□ Implementation of this strategy is limited by technical feasibility

□ Analysis and evaluation operational data (vehicle schedules) required

Operational expenses

□ „Opportunity Charging“

▪ High charging power („fast charge“)

▪ Infrastructure in the city

▪ Implemented in:

Münster, Cologne, Berlin, Hamburg,

Oberhausen, Braunschweig, …

Different Charging Concepts

Terminal stop 1 Terminal stop 2

□ „Depot Charging“

„Overnight Charging“

▪ Large batteries

▪ Infrastructure only in bus depot

Technical and Operational Feasibility AnalysisExample: bus route 130

■ Diesel bus operation

□ 3 vehicles; total deadhead: 31,1 km Best case, minimum vehicle number

and minimum deadhead

■ Operation with Depot Charger (350 kWh) and additional fuel heater

□ 4 vehicles; total deadhead: 56,6 km additional vehicle and 2 charging

phases during the day required

■ Operation with Depot Charger (250 kWh) and additional fuel heater

□ 4 vehicles; total deadhead: 73,5 km additional vehicle and 4 charging

phases during the day required

■ Operation with Depot Charger (250 kWh) and pure-electric heating

□ 5 vehicles; total deadhead: 99 km el. heating reqiures 2 additional

vehicles and 6 charging phases during the day

■ Electric buses will not replace conventional buses 1-by-1

■ Electric buses are not a solely technical issue Significant changes in many fields are required

□ Operation strategy: number of vehicles, deadhead and driver time

□ Workshops (vehicle maintenance)

□ Bus depot: additional space required

■ Each city (each bus network) has individual characteristics that impact the choice of the most suited electric bus concept.

■ Dedicated planning algorithms tailor the system to the local-specific requirements (route characteristics, infrastructure, timetables and current planning practice)

■ Experience from other cities available
