Abstatt – The integration of an electric inboard motor into recreational boats or commercial vessels involves considerable engineering effort and requires a high level of understanding of the overall system. The complete system electric drive for marine applications (EDM) from Bosch Engineering enables fast and simple high-voltage electrification. Boatbuilders, system integrators, and naval architects benefit from this when equipping motorboats, sailing yachts, catamarans, and smaller commercial vessels.

Plug-and-play for modern boat building

Bosch Engineering delivers the EDM as a ready-to-install inboard motor, which combines the electric motor with gearbox, the inverter, the on-board charger, the heat exchanger, an E-box with control unit, and the necessary cooling pumps in a single compact unit. The scope of delivery of the system also includes the high- and low-voltage cabling, a charger inlet along with a display and control elements. But hardware is only half the story: the complex control software offers extensive application flexibility to precisely calibrate and tune the propulsion system to the respective vessel.

High power density and installation flexibility

With a continuous output of 160 hp or 120 kW and weighing only around 195 kg, the EDM sets standards. The resulting high power density of around 0.6 kW/kg makes it one of the leading direct-drive inboard solutions in this performance class.
The installation dimensions of the compact EDM unit are comparable to those of an inboard combustion engine with the same power output and offers great flexibility for mechanical integration. Thanks to a shaft coupling that can be tilted by +/- 8 degrees fore or aft, the motor can be aligned precisely with the propeller shaft and installed flexibly in either direction depending on the available onboard space. This enables easy integration into an existing hull design or replacement of the drive as a retrofit solution.
In addition to cooling the integrated drive components, the thermal management of the EDM also ensures effective temperature control of the high-voltage battery. The high-voltage battery is not included in the scope of delivery. The standardized communication interface of the EDM ensures software compatibility with various high-voltage batteries on the market. This provides customers with great flexibility to choose freely based on their specific requirements and space constraints.

Automotive-grade quality flexible from quantity one

Bosch Engineering supports EDM customers from the initial installation concept to the eventual commissioning of the drive on the water. The system components of the EDM are sourced from Bosch's production for the automotive sector and satisfy the high quality standards of the passenger car and commercial vehicle segments. Bosch Engineering supplies the EDM complete system from quantity one, making it possible to economically electrify even custom one-off projects and small series.

Impressive driving dynamics in the demo boat

Bosch Engineering demonstrates just how well hardware, software, and system integration are coordinated as a complete system with a 6.5-meter-long sports boat on the water. With a peak output of 140 kW or 190 PS, the test boat proves just how dynamic this technology is. It accelerates to planing speed in just four seconds and reaches its top speed of 30 knots after 14 seconds. The EDM system in maneuvering mode demonstrates that this power can also be controlled with high precision: This special control function enables sensitive and controlled maneuvering in the harbor, even in the tightest berthing situations.

The Electric Drive for Marine Applications (EDM) will be presented at METSTRADE in hall 1 Stand 01.462.
