"Stuttgart transport operator SSB has put in operation the charging infrastructure at its Stuttgart‑Möhringen bus depot. The facility features 28 charging points capable of supplying up to 180 kW each, allowing simultaneous overnight charging of 28 electric buses. Additional buses can be charged during the day. The installation, carried out by Daimler Buses as general contractor, was completed in cooperation with Daimler Buses Solutions GmbH and partners Omexom and Power Electronics."
"The depot currently accommodates ten Mercedes eCitaro G articulated battery-electric buses and ten eCitaro G fuel cell buses, delivered in April, all equipped with the latest NMC3 battery technology. An additional 43 vehicles-including eCitaro, eCitaro G, and eCitaro G fuel cell buses, some with NMC4 batteries-are scheduled for delivery by October 2026. Buses charge using integrated pantographs in a "panto down" configuration. Charging voltage reaches up to 720 volts, with power levels of up to 180 kW, depending on battery state, the manufacturer says."
"The articulated battery-electric buses carry seven high-voltage battery packs totaling 686 kWh, while the fuel cell variants carry four packs totaling 392 kWh and six hydrogen tanks with 30 kg H₂ capacity, allowing a range of up to 200 km. Load management software optimizes energy distribution and vehicle readiness."
The Stuttgart‑Möhringen depot operates 28 charging points capable of supplying up to 180 kW each, allowing simultaneous overnight charging of 28 electric buses and additional daytime charging. Daimler Buses served as general contractor with Daimler Buses Solutions GmbH, Omexom and Power Electronics completing the installation. The project received roughly €13 million in state grant funding under LGVFG. The depot currently houses ten battery-electric eCitaro G and ten fuel-cell eCitaro G buses, with 43 more eCitaro variants due by October 2026. Vehicles use integrated pantographs in a "panto down" configuration at up to 720 volts. Battery capacities and hydrogen tanks provide up to 200 km range. A turnkey solution included steelwork, full electrical installation, the Sinos charging management system, and a three-year service contract providing 24/7 support, spare parts and annual DGUV safety checks.
