Charging systems for ships and ports - flexibility of the charging technology and power

The hybridization and electrification of ships also entail a demand for high-performance charging infrastructure. Baumüller closes the gap from the drive system to the charging station and offers the full range of charging technology for both rapid charging systems and shore power. Ports with shore-to-ship power benefit twice. With the sale of power, they open up a new business model and also reduce CO2 emissions and noise at the landing stage.

Baumüller’s different charging solutions for hybrid and fully electric ships demonstrate high flexibility. A precisely tailored system architecture for fast charging can be provided to suit the type of ship and the use to which it is put. This ranges from autonomous telescopic charging via loading crane to ram charging systems to manual charging stations.

Baumüller is also flexible regarding the power demand of the charging points and is not limited to predefined default values. It is therefore possible to individually meet the customers’ wishes. The bandwidth extends up to 5.6 MW. The fast charging stations can be equipped with CCS2 connectors, which enable both alternating current and direct current charging.

Baumüller closes the gap between the drive system and the charging station and offers the complete charging technology, not only for quick-charging systems but also for the onshore power supply.

Baumüller is a partner of shipyards, system integrators and ship owners and is itself a supplier of complete systems.

Baumüller customers benefit from:

  • Our own broad range of products and services from the converter through to the energy management and battery management system
  • Know-how: High-quality and reliable products for charging stations
  • Continuous engineering
  • Fast and customer-focused decision-making routes: The experience and advantages of a worldwide operating, successful and innovative family business with tradition
  • Worldwide service

Charging points: Precise-fitting system architecture for quick charging

We offer the charging infrastructure you want for nighttime charging and periodic charging: Innovative charging solutions for hybrid and fully-electric ships.

We support you with precisely what you need for your order and undertake projects, not only for the charging technology alone but also for charging and drive technology, and work with you to close the gap in your existing technology.

Charging stations at ferry berths

Are you looking for an innovative charging system? In a DC quick-charging system, the mains inverter from AC to DC is located at the ferry berth. Additional battery storage can reduce the mains connected loads and thus enable cost-optimised supply.

The necessary infrastructure on the ship is therefore small and the battery capacities on the ship can be reduced due to the availability of higher charging capacities. This saves weight and optimises the usable space on the ship. With this concept, the charging stations make emission-free shipping even more appealing.

Our know-how extends from manual charging stations for nighttime charging with plugs and a maximum charging capacity of 22 kW, to manual charging stations with CCS2 standard and a charging capacity of up to 425 kW per plug through to automatic charging stations, either via a tappet with plug or a crane solution with up to 4MW of power.

We also demonstrate our flexibility in the different charging solutions for hybrid and fully-electric ships. We offer the following standard alternatives:

  • Autonomous telescopic charging via loader crane
  • Tappet charging system
  • Manual charging stations

The charging period depends on the number of plugs. We offer CCS 2.0 sockets up to max. 500 A, depending on the drive dimensioning and charging time. In future, this will be extended to up to 3,000 A per plug by the MCS standard.

manual charging station for the MS CeresioFully charged in 20 minutes Fully charged in 20 minutes: The manual charging station was designed to precisely fit the MS Ceresio

Charging point, passenger ship MS Ceresio

Baumüller, together with the Società Navigazione del Lago di Lugano (SNL), electrified the MS Ceresio that was built in 1931 with a diesel drive, and also planned and implemented the quick-charging system.

The ship has an 840 kWh battery and is fully charged in only 20 minutes by a manual charging station. A 2 MW transformer was installed at the charging point for the quick charging.


Onshore power supply: Emission-free and cost-effective during laytimes

Onshore power supply: Emission-free and cost-effective during laytimesSource: ZinusUntil now, diesel generators had to secure the power supply so that the on-board system also functioned during laytimes in the port. An environmentally-aware alternative for the power supply is the onshore power system. Onshore power systems use the onshore electricity system and thus enable emission-free power supply for onboard services.

Onshore power supply systems are located directly at the berth in a port or even on a landing stage and are also more cost-effective to operate than units run on marine diesel.
