Verkehrsbetriebe Hamburg-Holstein GmbH (VHH) is a partner in the Hamburger Verkehrsverbund and operates 160 lines with around 2,100 employees and over 670 buses at 12 locations in Hamburg and Schleswig-Holstein.

The subject of the present procurement procedure is the conclusion of a framework agreement on the supply, construction, installation/assembly and commissioning of charging infrastructure for electric buses and the necessary electrotechnical equipment. The aim of the present tender is the binding procurement of a total of 78 DC charging points (binding purchase quantity) as well as a further 100 retrievable charging points (non-binding purchase quantity), including the foundation and the associated electrotechnical infrastructure. The calls of the additional 100 charging points are to take place by the end of 2027 in separate annual calls (approx. 25 pcs per year with a maximum of 3 calls).

Verkehrsbetriebe Hamburg Holstein GmbH intends to fully equip the Bergedorf depot with charging infrastructure for battery-electric buses from 2023. The area currently used for diesel buses will offer a parking for a total of 78 + 8 vehicles in a separate test lane.

The traction batteries of the vehicles are to be charged during the operating breaks. For recharging the battery system, the CCS charging interface (CCS Type 2, Combined Charging System, System C according to DIN EN 61851-23, configuration FF according to DIN EN 62196-3) for direct current charging (charging mode 4 according to DIN EN 61851-23) must be provided taking into account the standards DIN EN 62196, DIN EN 61851 and ISO 15118. With reference to the authentication and authorization of a loading process, the message set "Plug and Charge" from ISO 15118-2 must be implemented. In order to ensure the highest degree of interoperability between the systems, existing conformity tests in accordance with ISO 15118-4 or ISO 15118-5 and, if applicable, available amendments from CharIN e.V. are relevant for CCS 2.0.

The aim of the present tender is the binding procurement of a total of 78 DC charging points (binding purchase quantity) as well as a further 100 retrievable charging points (non-binding purchase quantity), including the foundation and the associated electrotechnical infrastructure. The calls of the additional 100 charging points are to take place by the end of 2027 in separate annual calls (approx. 25 pcs per year with a maximum of 3 calls).

All charging points should be able to independently provide at least 200 A of charging current and at least 150 kW of charging power. If required, the power per charging point must be dynamically controlled by a higher-level external charging management system. All contacts of the vehicle coupling must always be voltage-free without connecting a vehicle. Only after the secure contact closure and locking on the vehicle may a voltage apply.

The requirements of DIN EN 61851 and ISO 15118 apply.

In addition to the delivery of the charging infrastructure, the procurement includes the delivery of the complete necessary electrotechnical equipment such as the depot box, the CCS cable as a complete unit and the cable laying work. All components to be supplied must be fully assembled, connected and put into operation in accordance with the recognised rules of technology.

Regardless of the grid connected power, each charging point should be able to provide at least 200 A of charging current with at least 150kW charging power at the same time. If required, the power per charging point must be dynamically controlled by a higher-level external charging management system.

Calibration-compliant measuring points and data points must be provided in all outlets, between all voltage levels and at all other technically sensible points in order to ensure the possibility of a comprehensive energetic evaluation.

The control of the charging infrastructure is to be carried out in accordance with the OCPP 1.6J standard. An upgradeability to OCPP 2.0 or current OCPP standards at the time of commissioning must be given. The control and evaluation of the AC voltage technology is to be carried out via IEC 61850.dem or IEC60870-5-104 as well as Modbuc TCP protocol standard (protection technology in Goose). The possibility of connection via TCP-IP to an external control technology (such as VIVAVIS or Stausberg and Vosding) must be provided.

Communication between the charging infrastructure and the vehicle must be carried out in accordance with the ISO 15118 standard (latest version).
