Terra Modena (TMM) is a Research and Development laboratory specialized in the design and production of EIPS [Electric Integrated Propulsion System] for high power electric boats.
We have a long experience in the automotive sector, but since 2016 our focus has been on high performance Zero Emission electric boating.


We also carry out complete hybrid / electric propulsion projects on the Customer's instructions: in this case we integrate endothermic engines ICE with high-power radial or axial flux electric motors, powered by the latest generation energy systems. Our service also includes the assembly phase at the Customer's shipyard, water tests, guarantees and the necessary certifications (RINA and BUREAU VERITAS).


We do not have a range of standardized products but we work on Customers’ on demand projects. The EIPS system includes the high-power electric propulsion part, the electronic control and management of the system, including: throttles, display, Data Logger, Energy Storage, inverters, motors, power electronics, control electronics and charging system.
In case of an hybrid propulsion we also supply all the mechanical connections and operational interfaces between the internal combustion engine and electrical machines.

For the transmission and the propellers, at the Customer's request, we use a predictive mathematical simulation model, developed with a well-known company and leader in the sector with which we have a strategic technical partnership. Our experience has taught us that the optimization of performances depends from the predictive mathematical evaluation of the propulsion's characteristics in accordance with the water lines of the hull together with the weight and center of gravity of the boat.

-The software is designed and developed in house, so we are responsible for the correct operation of the electronics.
-We use hardware, electrical and mechanical components of the highest quality standard.


→ Electric motors: axial or radial flux, with peak powers from 20 to 400 kW with electronic control optimization, aimed at obtaining a torque and power response according to the needs and characteristics of the boat;
→ Programmable power electronics on project specifications;
→ Electronic safety systems;
→ Military or Motorsport specific wiring and connectors;
→ Vehicle Control Unit, equipped with CAN communication, analog and digital inputs & outputs;
→ Handcuffs and power delivery system;
→ Dashboard with configurable screens to display all useful information during navigation.
→ Charging system;
→ Portal with an alert system via 4G SIM card that will allow the Customer to monitor 'remotely' the operating parameters of the boat while in navigation.


We have modules complete with Battery Management System (BMS), with energy starting from 42kWh up to 180kWh single modules, which can be coupled. We have two technology:

→Until 2019: Lithium Polymer batteries.
→From 2020: “BB technology”. It is an innovative and patented energy system, developed by a group of International Researchers of which Terra Modena has the exclusivity for nautical use.
→“BB technology” is Terra Modena's exclusivity for the boating industry.
→The very small size and extraordinary energy density of “BB technology” will allow us to offer the market a range of “catalog” electric propulsion systems for any retrofitting need.

We have also developed a hybrid electric / hydrogen project but we consider this configuration too complicated and expensive for boats other than large ships, oil tankers, container ships, etc.
