High-Capacity eBus for Urban Public TransportTOSA - 15 Seconds Flash Charging

Olivier Augé / Global Product Manager, September 2014


Agenda

§ The meaning of the project

§ The concept and the technology

§ Operational experience and next step


Sustainable mobility challengesPublic transportation

§ An increase in urbanization and high mobility demands

§ Traffic congestion§ The need for a transport system with high capacity (BRT)

§ Public health: reduction in CO2 and noise emission§ Evaporation of carcinogenic substances (OMS) coming from diesel

motors Group 1 (since 2012)

§ Imagine vehicles with high energy efficiency

§ Flexible system to be deployed rapidly


TOSA demonstrator projectThe Partners

The four partners of the pilot project:

ABB: Technology provider

TPG: Operator

SIG: Energy supplier

OPI: Project coordinator

Next stepsProject and Technology

§ TOSA pilot-route – Geneva, bus line 23

§ Technical progress


TOSA in GenevaAfter the demonstratorà Line 23: 14km-long line with 12 articulated bus

Tribune de Genève,12.3.2014 Agenda 2014-2018Department of the Environment, Transport andAgriculture (DETA), published 14.4.2014


TOSA pilot-route – Geneva, Bus Line 23Technical Configuration

Configuration of the vehicle (x 12):§ Battery: 2 * 41.4kWh§ Passenger number: reduced from

133 to 124 because of the weightof the battery

Operational use (time at the terminusstops):

§ Terminus Ià II : 3’07 (19 pass.)and 4’17 (78 pass.)

§ Terminus IIà I: 2’55 (19 pass.)and 4’ 22 (78 pass.) Currentlybetween 4’ and 7’ dependingtimetable

Technical progress vs. Demonstrator projectVehicle Equipment


LiTO batteries: Same technology but new modules§ 33% less heavy and 33% less volume

Inverted rectifier of the drive used as charger§ Disposal of the allocated charger

ETS: Recognition of the infrastructure type and automatic equipment of theconnection arm

§ Increase in information amount and independence vis-à-vis SAIEV

Technical progress vs. Demonstrator projectInfrastructure


Height under the girder: >4.5m§ According to European legislation

Coil moved to feeding side§ Reduction of the weight of the vehicle

Flash with or without storage§ Size reduction of infrastructure

Energy storage: Super capacityà Lithium capacitor§ About 2/3 reduction of the storage size for same capacity

Flash : charger of middle frequency with IGBT technology§ Reduction of the harmonization rate on the network and the charger size


High Capacity Concept for High Frequency and eBRT133 to over 210 passengers
