TOSA Flash Mobility, Clean City, Smart

Power Supply”. It originally stood for Transports Publics Genevois, Office de la Promotion Industrielle, Services Industriels de Genève and ABB Group, the four partners of the demonstrator project TOSA2013[1]

3 The technical concept

The energy is collected along the route at some dedicated bus stops (every 3rd or 4th bus stops) while people are disembarking and embarking. Thus, there is no impact on the timetable. The automatic electric connection is made TOSA Energy Transfer System from the top within 1 second while the bus is stopped at the bus stop. Than charging is made at high power (400 The TOSA concept and test bus is a full large capacity kW on the demonstrator) during the 15 seconds the door urban battery system developed in Geneva by remains open. At the terminal, the battery is topped up ABB Sécheron, a subsidiary of the ABB Group. within 3–4 minutes.

1 Aim of the concept and project 4 The infrastructure

The aim is to provide a zero local emission mass public According to the line profile (total length and altitude) transportation bus system with high passenger capacity and service (frequency), the Flash Feeding Station (FFS) and no overhead line. are distributed along the line at some (each 3rd or 4th bus The concept supports same operating timetable and fre- stops - roughly 1.5–2 km) intermediate bus stops.
