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

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

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
