TOSA (bus)

The TOSA concept and test bus is a full large capacity urban battery electric bus system built by Carrosserie Hess and developed together with ABB Sécheron, a subsidiary of ABB.

The aim is to provide a zero local emission mass public transportation bus system with high passenger capacity and no overhead line.

The following aspects have been considered to comply with a sustainable mobility approach: TOSA stands for Transports Publics Genevois, Office de la Promotion Industrielle, Services Industriels de Genève and ABB, the four partners of the demonstrator project TOSA2013[1] The energy is collected along the route at some dedicated bus stops (every 3rd or 4th bus stops) while people are disembarking and embarking.

Then charging is made at high power (400 kW on the demonstrator) during the 15 seconds the door remains open.

According to the line profile (total length and altitude) and service (frequency), the Flash Feeding Station (FFS) are distributed along the line at some (each 3rd or 4th bus stops - roughly 1.5–2 km) intermediate bus stops.
