Powerful and compact Bosch engine creates new opportunities for boat builders

Bosch Engineering is launching a newly developed and powerful electrification solution for electrical systems with voltages up to 800 volts. This solution expands the range of applications for electric boats while increasing the efficiency of the systems.

Bosch's latest generation of electric motors and inverters with silicon carbide modules offer a complete system that enables recreational boats, larger sailboats and workboats to be powered efficiently, quietly and with high power.

The new SMG 230 electric motor is designed for system voltages between 400 and 800 volts. Under ideal conditions, it can provide a continuous power output of up to 200 kilowatts and a torque of around 250 Newton meters. Thanks to the 800-volt technology, the power density of the motor has increased significantly. The SMG 230 provides 80 kilowatts more than a similar 400-volt motor of the same weight or offers the same performance in a more compact and lighter format.

The silicon carbide semiconductor inverter, also designed for up to 800 volts, has an impressive efficiency of over 99 percent. The faster switching processes in the silicon carbide semiconductors minimize energy loss in the form of heat, further increasing efficiency.

Bosch offers a complete boat electrification kit, with controllers, inverters, electric motors and switches adapted for both 400- and 800-volt solutions. This gives shipyards and system integrators maximum flexibility to customize electrification to specific needs and to easily integrate the various components into their vessels. The system components are based on modern vehicle technology and are both robust and reliable. With its comprehensive electrification kit, Bosch contributes to reducing greenhouse gas emissions and noise in maritime environments.
