Unique in being modularly built, designed to be quickly and easily assembled, customizable in motor power and battery capacity, equipped with smart software that automatically manages consumption levels, suggests travel modes, and much more.

Each component (electric motor, battery bank, etc.) is fully modular and ready to plug&play. The end-user can choose the optimal solution (propulsion power, battery capacity, charging time, ...) for his own needs and each deployment is capable of being customized. Future scaling is also possible and very simple. Same as a new installation, scaling is also plug&play. This makes the retrofit very effective and reasonable.

NT Systems can be used in various applications where there is a need of reducing pollution, operating or manufacturing costs. Recreational and transfer boating is initial roll-out market, including tourist or cargo transportation for river or channel crossing, small ferry, taxi boats, harbour applications, work platform/barges, service crew, marina crew, rescue crew, coastal diving centres, coastal security and police boats, smaller towing applications, by-boats for ocean cruisers or personal use, island cruising, fishing boats, aquafarming, leisure personal boats and yachts, sailboats and much more. It is also very convenient for eco-sensitive environments such as lakes, rivers, national parks, city canals etc.

Consumption optimization

Optimal power tracker (OPT) can automatically optimize consumption based on battery SOC, GPS log data, select user mode, etc.

Electric motor

Motor unit is preassembled

We are using a permanent magnet synchronous motor with best in class power density, which is up to 10 kW/kg peak power. The performance is by itself state-of-the-art, while still being low weight and plug&play: you only mount the motor into the boat, connect the power supply, the communication cables, the seawater for cooling and it is ready for operation.

Plug-and-play motor unit includes prewired and premounted: electric motor, optional gearbox, drive controller, cooling pump for inner circle (glycol), cooling pump for outer circle (seawater), a heat exchanger between inner and outer circle, filter for seawater, expansion tank for an inner circle, electronics with CANbus communications (ECU), all the water plugs, all the electrical plugs and motor mounts.

The design supports multiple-motor installations and thus increasing the propulsion power, which expands modes of applications and usefulness. The power options of an individual electric motor are in the range 25-350 kW of continuous power which brings universality to the system. Stacking the motor to a quadruple set can easily provide 1400 kW (1880 HP) or more if necessary.

User control

Throttle lever

The throttle lever is engineered in-house and specifically designed for electric propulsion. It is simple and ergonomic, with all marine functions. It supports control over multiple-motor installations and multiple stations, while Dock assistant feature will help with complex and precise manoeuvres.

Display

The user interface is intuitive and easy to use. It shows all important data on the home screen. An overview of all parameters from system components connected through CAN bus is available in submenus. Resulting in being used as a handy tool for any service without major intervention.

The system features also remote access, with an additional hotspot or ethernet connection, which will allow a unique customer experience, remote system updates, customisations and customer service.

Optimal power tracker

OPT can optimise numerous parameters, make predictions on energy and power needs, optimise energy and fuel consumption, select smart mode (when to start range extender regarding prediction, SOC of battery, environmental factors such as temperature, noise level, etc.), customisation, different pre-sets for different users and other more basic tasks. The optimization of best-case scenario will not be based only on current driving parameters, but also on data from previous trips.

Battery bank

Batteries are an essential part of electric propulsion. Safety and reliability are very important factors within the system. Therefore, we support and supply manufacturers with extensive marine experience.

Optional range extender (internal combustion engine or fuel cell) can be connected to the battery bank serving as a generator, allowing to extend the range of propulsion system or combined hybrid use.

Future development

Our development team is already working on features such as dock parking automation, sky-anchor (position maintenance via GPS without anchoring) and other intelligent applications. The software itself is modular, so upgrades will be easy to install.

Engineers are already preparing 500 kW motor. Stay tuned or contact us immediately if you would already like to hear more details.

About us

NT Electric was established in 2018 out of 2014-borne sole-trader entity and founded the NT Systems brand. The company is based near Kranj, Slovenia, 15min from Ljubljana airport. The team consists of 8 full time employees, experts in boating propulsion systems, electric engineering and electric systems development. Background of our staff includes track record in business and boating industry, and development of Greenline vessels, the biggest hybrid fleet in the world in the class 10-20 m.

Based on past experience from hybrid world and daily encounters with integrating complex systems into yachts, the idea of advanced plug-and-play electric propulsion was born. The aim was to develop innovative electric propulsion technology, specifically designed for water-borne usage, coming with a disruptive motor cooling system, high-performance and easy plug-and-play installation.
