Lexicon

Welcome to our glossary. You will find clear and concise definitions of essential terms related to our business. We want to offer you a quick and accessible understanding of the key concepts related to electric motorization for boats.

These boats are used by ports, local authorities and river operators. They benefit greatly from the reduced maintenance costs made possible by electrification.

Navigation

Shell

The main structure of the boat, which gives it its shape and ensures its buoyancy.

Navigation

Skipper

A person who steers a boat. This may be a professional captain or an experienced recreational boater.

Navigation

Starboard / Port

Starboard = right side of the boat (as seen from the stern). Port = left side of the boat.

Sustainable development

Sustainable development aims to meet current needs without compromising those of future generations. In boating, this involves reducing pollution, adopting clean engines and sailing in a way that respects ecosystems.

Environnement

Système de propulsion

Le système de propulsion désigne l'ensemble des éléments qui permettent à un bateau de se déplacer. Pour Weenav, cela fait référence aux moteurs électriques, aux systèmes de gestion de l'énergie, et aux moyens de recharge. Ce système peut être conçu pour être totalement électrique ou hybride, en fonction des besoins du bateau et des usages prévus.

Moteurs

Torque

Torque is the rotational force generated by the motor, expressed in Newton metres (Nm). Weenav electric motors are distinguished by their high torque, enabling immediate and efficient acceleration, even at low speeds.

Moteurs

Tourist boat

Tourist boats carry passengers on sightseeing trips or discovery tours. Electric propulsion offers a quiet, pleasant experience that is more respectful of the natural environments being observed.

Navigation

Underwater noise

Underwater noise consists of sounds generated by ships and human activities. This noise disturbs marine wildlife. Electric propulsion significantly reduces this disturbance.

Environnement

Yachting

All recreational activities carried out with sailing or motor boats, often for leisure purposes.

Navigation

foghorn

Audible signal used to warn other vessels, especially in poor visibility.

Navigation

État de charge (SOC – State of Charge)

SOC corresponds to the percentage of energy remaining in a battery relative to its total capacity. For example, an SOC of 100% means that the battery is full. Weenav navigation screens display the SOC in real time, helping to anticipate the remaining range.

What is a retrofit?

The transformation of a thermal vehicle (car, boat, bus...) into an electric or hybrid vehicle, also called retrofit, involves the replacement of the combustion engine by an electric motor or the integration of a hybrid system. This includes installing batteries, an electric motor, controllers, and other components needed to provide electric propulsion. This process reduces greenhouse gas emissions while increasing the vehicle's fuel efficiency.

What is the energy consumption of an electric motor?

Our electric motors range from 50 kW to 400 kW. At low speeds, consumption can drop to 10 kW, which ensures a minimum autonomy of 10 hours on any boat, depending on specific sailing conditions and battery capacity.

What is the maintenance difference between electric and thermal motors?

Electric motors require less maintenance than internal combustion engines due to their mechanical simplicity (fewer moving parts) and the absence of certain critical components such as oil filters, spark plugs, etc. Electric motor maintenance focuses primarily on maintaining electronic systems, batteries, and the motors themselves, with less need for mechanical adjustments or frequent replacement of parts.

What advanced technologies are used in electric motors?

The advanced technologies used in electric motors are high-performance permanent magnets, vector control and oriented flow controls (FOC), advanced sensors, variable frequency drive (VFD), improved cooling, monitoring and self-diagnosis systems, modeling and simulation, modeling and simulation, modeling and simulation, compact optimized coil technology, compact optimized coil technology, optimized compact coil technology, cooling at the core of the rotor optimizing efficiency as well as the development of the dashboard with a connection of information between them.

What are the ecological advantages of electric motors?

Electric motors offer undeniable ecological advantages by reducing local emissions of exhaust gases and particulates, by reducing the carbon footprint through the use of renewable electricity, and by minimizing noise pollution, thus maintaining marine ecosystems. Their design with fewer moving parts and simplified maintenance also contributes to reducing the overall environmental impact while meeting strict environmental standards.
