Metropolitan Paris area launches trials of the 100% electric Tzen 4, funded by Île-de-France Mobilités

This vehicle, designed for Île-de-France Mobilités by the consortium Van Hool – Kiepe Electric – Alstom, embarked on its inaugural journey at the Corbeil-Essonnes Bus Operations Centre, Île-de-France. What advantages does the service with this bus offer?

Alstom, global leader in smart and sustainable mobility, is supplying the static ground charging system (SRS) for the Tzen 4 bus, the first double-articulated, ground-recharged electric bus, 100% financed by Île-de-France Mobilités.

This vehicle will eventually equip the Tzen 4 line, between Viry-Châtillon and Corbeil-Essonnes RER station, as well as the new Tzen 5 bus line, between the 13th arrondissement of Paris and Choisy-le-Roi.

This innovative and sustainable transport solution from the Van Hool – Kiepe Electric – Alstom consortium is made up of 24-metre-long, bi-articulated Van Hool electric buses powered by Kiepe Electric’s high-power, fast-charging battery systems that will be charged by Alstom’s SRS system.

“For more than 20 years now, Alstom has been developing and deploying catenary-free static and dynamic ground charging solutions (APS for trams and SRS for trams and electric buses). These solutions are used in a dozen cities around the world. Trams equipped with APS have already covered more than 70 million kilometres,” states Jean-Baptiste Eyméoud, President of Alstom France.

“Today, I am delighted with this world première: the first circulation of the Tzen 4 bus, 100% electric, bi-articulated and recharged on the ground thanks to our proven and innovative SRS system,” he adds.

Alstom’s SRS solution for electric buses offers numerous advantages to cities and bus operators alike.

SRS is a safe, ground-contact static charging system that recharges on-board equipment automatically, at very high power and in just a few minutes.

Charging can be conducted either on a bus line during operation or in a depot when the vehicle is not in service.

Thanks to its positioning on the ground, Alstom’s SRS solution does not require overhead infrastructure and blends naturally into the urban landscape. SRS is a highly reliable and modular system that is designed to be interoperable and compatible with all types of electric buses.

This means it can be deployed across multiple fleets, regardless of the manufacturer or variations in battery technology.

Alstom’s SRS solution is a technology of the future.

For the development and deployment of the SRS solution for electric buses on the Tzen 4 and Tzen 5 lines in the Île-de-France region, Alstom is relying in particular on the excellence of the teams at Vitrolles site (Alstom’s global development centre for underfloor power supply solutions), to design the product,
and the Infrastructure & Systems teams, in charge of engineering, installation and tests.
