The new order means that a fifth of Wiesbaden’s buses will be electric
Mercedes‑Benz has received a record-breaking order for the eCitaro electric urban bus. This massive order comes from the public transport company ESWE Verkehrsgesellschaft from Wiesbaden in Germany’s Hesse region.
As a provider of comprehensive electromobility solutions, Mercedes‑Benz does not just deliver electric buses, it also takes care of the adaptation of the service yard, the equipment and setting up of charging infrastructure, as well as the charging management process itself. With this commission, the city of Wiesbaden is switching a fifth of its bus fleet to electromobility within a short period of time.
Head of marketing, sales and customer services at Daimler Buses Ulrich Bastert said: “Due to its outstanding features, the new eCitaro has won through in no time. Wiesbaden’s invitation to tender however also shows the systemic challenges involved in the introduction of e-mobility, which we are happy to play a part in.”
Managing director at ESWE Frank Gäfgen said: “We are now starting to realise our vision of emission-free driving in Wiesbaden’s public transport. And in this regard, we want to take the lead in Germany.”
The first 15 eCitaro for Wiesbaden will be equipped with current-generation lithium-ion batteries. These are NMC batteries (lithium-nickel-manganese-cobalt-oxide cells). Each eCitaro is equipped with 12 battery packs with a total capacity of 292 kWh.
The remaining 41 eCitaro will be equipped with solid-state batteries. With this new battery technology, the eCitaro once again takes on a leading role, and is even among the pioneers in automotive construction.
Solid-state batteries have a very high energy density. In this case, seven battery packs are sufficient in order to provide a huge battery capacity of 441 kWh. Even in winter when faced with the difficult demands of using all-electric heating, the eCitaro can still cover more than 200 km according to the SORT 2 testing method. All 56 buses are charged by plug in the depot.
Charging management is also part of the order. It will be realised together with the Berlin-based partner company IVU Traffic Technologies, a renowned specialist for customised IT solutions.
First of all, this involves assigning each bus a defined charging point upon arrival at the depot. Smart charging management ensures that all buses are charged with the necessary amount of electricity for their next trip. This also includes preconditioning, i.e. the temperature control of the passenger compartment and batteries, and thus ensures maximum efficiency.
