Continuous power at the service of your nautical performance
Weenav reaches a historic milestone in the nautical industry with its KRONOS engine. Where traditional electric propulsion limited their performance, KRONOS delivers 300 horsepower of continuous power, constant, with absolutely remarkable performance peaks reaching 408hp. This technical feat redefines market standards and opens a new era for sport electric navigation.
Weenav, pioneer of high-performance electric propulsion
Weenav establishes itself as the architect of a silent but powerful nautical revolution. Our mission: to design mais puissante. Notre mission : concevoir des 100% electric propulsion solutions that compete with and surpass traditional thermal engines, without any compromise on performance. With the KRONOS range, we demonstrate that ecology now rhymes with technological excellence.
An unprecedented technical architecture
Exceptional power and efficiency
The KRONOS 300 develops more than 300 horsepower continuously (220 kW), a peak power of 408hp (300kw) with a propeller torque of 752 Nm available instantly from startup. Its efficiency of 97% shatters the performance of thermal engines, transforming every electron into pure propulsion. This efficiency translates into a maximum range and operating costs reduced by a third.
Next-generation battery technology
At the heart of the system: LFP Solid State battery modules (Lithium Iron Phosphate with solid electrolyte), a revolutionary chemistry that guarantees absolute safety, zero risk of explosion or flammability. Each module weighing 49.5 kg and 35 litres is strategically distributed within the hull to maintain the optimal centre of gravity of your vessel.
With 11 battery modules, you benefit from an energy capacity of 56 kWh. These modules boast an exceptional lifespan of 6,000 full cycles, equating to an estimated longevity of 30 years. At the end of their life, they are 97% recyclable, placing your navigation in a resolutely sustainable approach.
Current battery technologies allow for these power levels, ensuring optimal performance for all your navigations.
Ultra-fast charging: freedom regained
No more range anxiety. The KRONOS comes standard with a 22 kW onboard charger (three-phase 32A) compatible with standard Type 2 sockets. Need to set off quickly? The technology Combo CCS accepts the fast charging up to 200 kW (350 kW on certain infrastructures), allowing you to go from 10% to 90% in just 30 minutes. It's faster than filling up with fuel, with no smell or handling.
Reliability that redefines standards
The mechanical simplicity of the KRONOS is its main asset: 100 times fewer parts than a thermal engine. This streamlined architecture results in 100 times greater reliability and almost non-existent maintenance costs. The first service only occurs after 5,000 hours of operation, whereas a thermal engine requires repeated and costly maintenance.
The base, designed to support up to 780 Nm, ensures robustness and longevity. Certified IP67 (waterproof to 1 metre for 30 minutes) and operational from -20°C to 90°C, the KRONOS faces all maritime conditions with absolute serenity.
Smart connectivity by GARMIN
The partnership with GARMIN elevates your user experience to new heights.
The EmpirBus interface centralises all navigation and energy management data on a dual screen of up to 16 inches (12 inches included in the offer).
Intuitive control, perfect readability and total control, you benefit from direct access to alarms, notifications and essential information for safe and controlled navigation.
Navigation without limits or constraints
The KRONOS opens up all horizons: Marine Protected Areas, Low Emission Zones, sensitive mooring areas... Navigate anywhere, without environmental restrictions. Enjoy absolute silence, without vibrations or toxic emissions. Your comfort, that of your passengers, and the preservation of marine ecosystems finally reconciled.
