Farmington Hills – The electrification of cars and public transport continues to grow. A next step is to drive the electrification of maritime solutions to reduce environmental pollution and better protect lakes and rivers in metropolises worldwide. This is a trend seen at shipyards and many boat manufacturers. Increasing customer demands for an eco-friendlier solution are also spurring the industry on. Bosch Engineering therefore offers electrification solutions for recreational boats and motorized yachts, enabling shipyards, shipbuilders, and system integrators to implement drive electrification quickly and easily. “With our electrification solutions we intend to play a key role in driving this change in the maritime sector. Whether boat manufacturers require an individual or platform solution, we want to offer them the optimal solution for their needs. In addition to providing original equipment, our solutions can also be used to retrofit existing fleets of boats,” explains Philipp Kurek, who is responsible for off-highway and maritime solutions at Bosch Engineering.
Highly dynamic electric drive offers new degree of enjoyment
Boat manufacturers receive individual components that they can integrate into their systems themselves. The overall system for boat drive electrification from Bosch consists of an electric motor with an optional gearbox, an inverter with an integrated DC/DC converter, and an electric control unit as the system’s core component. The motors are available in 90 and 140 kW power levels. The design of the 400 V permanent magnet synchronous motor is characterized by a high-power density and very high efficiency. The inverter is equipped with a powerful DC/DC converter for supplying the 12 V onboard power supply system. The transmission impresses with its high efficiency and quiet, low-maintenance operation.
The compact dimensions enable boat manufacturers to easily integrate the components even into small spaces or to retrofit existing applications. The low overall weight of the components allows the maximum range of the boat to be increased. The dynamic behavior of the electric drive effortlessly drives pleasure boats and yachts and offers a new level of driving pleasure.
Outlook: Electric drive system platform – simple integration thanks to platform approach
With the electric drive system platform (EDSP), Bosch Engineering offers boat manufacturers a solution for electric boat drives. This comprises Bosch’s own drive components, such as the electric motor, inverter, and transmission, as well as solutions for all other relevant components, such as the high-voltage battery, charger, and cable harnesses that come from third-party providers. Users also receive a description of all the key information they need to incorporate the technology into their boat. This includes a system guideline, component specifications, electronic control unit software, and a commissioning packet. Ultimately, the EDSP approach significantly shortens the development time to series use. With the EDSP, boat manufacturers benefit from a predefined solution that can be installed quickly and cost-effectively in recreational boats or yachts. The EDSP will be available for the US market by end of 2024.
