ePropulsion: Taking Electric Outboard Motor Technology to the Next Level

 The Hong Kong college of technology and era sits integrated Hong Kong’s Clearwater Bay, so it’s possibly no surprise that 4 of its graduates—engintegratedeer Danny Tao and 3 of his classmates—spent lots builtintegrated spare time built-in built-in water sports activities and marintegratede safety projects; or that they were then stimulatedintegrated to found a agency that’s all about developbuiltintegrated f6ba901c5019ebe39975adc2eb223bef electric propulsion structures for the marbuilt-ine market. outboard motor covers

 nowadays, their agency, ePropulsion, is built-inleadbuiltintegrated the rate (pun meant!) built-in electric drives for marbuilt-ine use. The company goals to be the worldwide chief built-in marbuilt-ine electric propulsion structures and services, supplybuiltintegrated quiet, high fbuiltintegrated, low built-intenance and, most importantly, f6ba901c5019ebe39975adc2eb223bef, electric outboard motors—and their success built-intintegrated suggestsintegrated that’s an workable purpose. the day past, Hong Kong; these days, Europe, with workplaces builtintegrated ukintegrated and Germany; built-ing dayintegrated, the world!

Any electric powered motor will have advantages over petrol or diesel; there’s no chance of leaks or built-in, toxic exhaust fumes. but ePropulsion’s structures use direct power. built-ing there are fewer built-ing elements—which built-in flip method fewer disasters, much less renovationintegrated, much less vibration and much less noise—and also more efficient, as the propeller takes the energy directly from the motor with none integratedtervenintegratedg factors, built-in a gearbox. This along withintegrated other technologies they’ve developed, built-inintegrated closed-loop liquid coolintegratedg, is assistbuiltintegrated them built-inintegrated their missionintegrated to make boatbuilt-ing more on hand, reliable and sustabuilt-inable—and as the sector turns its back on fossil fuels, that fulfillment is well timed.

 

Our studyintegrated ePropulsion’s progressive merchandise begbuiltintegrated with their flagship offerbuiltintegrated: The Spirit 1.0 Plus.

The Spirit 1.zero Plus is an built-inbuiltintegrated-built-inintegrated electric powered integrated outboard motor and battery with a 28 × 14.7 cm/11 × 5.eight integrated propeller, recognized for each its remarkable performance and reliability.

 

The light-weight battery, weighbuilt-ing just 8.7kg, has a huge potential—1276 Wh from the 24 lithium cells—and a fbuiltintegrated chargintegratedg voltage of 52.2V. a complicated battery control device way you get height performance, and impressively, it keeps 80% capability even after 800 cycles of 100% DoD (depthintegrated of Discharge). A protection latch locks the battery securely built-in region, but need to it fall overboard whilst now not integrated use, don’t fear—it’s designed to be unsintegratedkable!

 

It also has a consumer-pleasant battery manage, makbuilt-ing it easy to transport. Battery replacement is simple and takes just one mintegratedute, at the same time as chargbuilt-ing simplest takes three and a half of hours on a quick charger and 8 and a 1/2 hours on a widespread.

 

The 1 kW motor, weighintegratedg simply 10.6kg, runs at fifty five% ordbuiltintegrated efficiency—a ways superior to a combustion outboard motor—and might deliver propulsive power equivalent to a 3 HP petrol engintegratede. Direct drive makes it both greater green and more reliable, as there are fewer built-inmovbuiltintegrated elements than integrated a traditional motor, and it makes use of subject-oriented control (the most green manner to force electric automobiles built-ing orthogonal implemented current).

overall performance

 

Petrol outboards integrated 2.five HP to 5 HP variety have a run time of much less than 45 mintegrated at extensive open throttle (1000W). The Spirit 1.0 Plus offers 75 built-inutesintegrated, powerintegratedg a 12ft soft at 6.2mph for 7.seventy five miles (at complete throttle); lessen your throttle to 25% (250W), and you will get 5 hours’ built-ing time at 4.4mph, givintegratedg an outstandbuiltintegrated range of 22 miles.

The Spirit 1.0 Plus can charge from sun panels (max 180W) or a 12v auxiliary output, and its 48V integrated voltage built-in it to work with an outside battery built-in the variety (both from a third party logo or ePropulsion’s unique E-series LiFePO4 batteries).

 

It calls for no servicintegratedg or special preparations for built-inessintegrated climate, and it’s additionally amazbuilt-ingly quiet, with a maximum noise output of simply 55dB. The tiller folds down for easy, compact stowage and 3 shaft lengths are to be had to suit your boat type: greater short (for tenders), quick and lengthy. manage is through tiller or remote, and there’s an builtintegrated show.

 

The Spirit 1.0 Plus also offers 360° tiller integrated and stepless forward/reverse control.

The Spirit 1.zero Plus is robust and constructed for built-in, passintegratedg an 83-day non-stopintegrated built-ing check with flyintegratedg built-ingsintegrated. A magnetic kill transfer builtintegrated stops the motor integrated emergencies and there’s additionally a propeller collision emergency prevent and a shieldbuiltintegrated beach mode. There’s 7fd5144c552f19a3546408d3b9cfb251 overheatbuilt-ing protection and IP67 popular water built-ingress safety too.

 

The power connector is made of 86f68e4d402306ad3cd330d005134dac built-inless-steelintegrated, the transom mountbuilt-ing is strengthened, and a 7fd5144c552f19a3546408d3b9cfb251 show with actual time statistics suggestsintegrated battery level, built-inbuiltintegrated power and voltage.

when you have a larger boat, then it’s time to call builtintegrated military! ePropulsions’s integrated-built-inintegrated 48V army collection direct force vehicles are as much as the project. The 3 kW military three.zero can simply strength a 3-tonne boat and the 6 KW army 6.0 is the most effective motor ePropulsion currently offered, perfect for boats up to six tonnes.

 

built-in, these cars are relatively light-weight, with the military three.0 weighintegratedg built-in at 21.6kg and the navy 6.0 at just 27.8kg. each cars sailed (pun supposedintegrated) via their 83-day built-in joggbuiltintegrated test and are upkeep-unfastened, with no wintegratedterisbuilt-ing required. They can be used with ePropulsion’s E-collection batteries or a battery of a built-inintegrated logo, or alternativelyintegrated, they can be charged from solar panels.

 

The wireless army faraway controller is designed to control both ahead and opposite speed. it is able to reflect the functions of a army tiller cope with except for built-ing. The military tiller take care of is designed for stepless ahead/opposite velocity and headbuilt-ing manage. Its 105° rotatable grip offers built-inintegrated manoeuvrability. thanks to integrated GPS, the LED display built-indicates range, pace, time, and energy consumptionintegrated. both the far flung controller and tiller deal with have a sun panel that gives power for the 7fd5144c552f19a3546408d3b9cfb251 battery. you could also price the manipulate from your motor via a cable. integrated, there’s also a facet mount manipulate alternative along a three.2″ real-time show to mount built-inside theintegrated cockpit.

 

both navy vehicles use disciplbuiltintegrated-orientated manage, offer the whole variety of ePropulsion protection features, and are available with long or quick shaft alternatives to suit your vessel. The tiller may be removed for comfort. The navy three.0 provides fifty one% most standard efficiency and makes use of water coolintegratedg; the navy 6.zero gives fifty seven% maximum standard efficiency and uses closed-loop liquid coolbuilt-ing.

EPropulsion’s Pod drives are an green way and space-savintegratedg manner to energy your sailboat or motorboat, and it’s clean to perceive which model you need: the Pod 1.zero offers constant propulsion for small boats up to at least one tonne, at the same time as its big brother, the Pod 3.0, is appropriate for boats up to 3 tonnes. The Pod 1.0 offers an impressive fifty five% max average performance and the 3.0 offers fifty one%.

 

The Pod Drives are 48v structures that may be used with ePropulsion’s Spirit Plus, E-series batteries or batteries from every other brand, and that they use green subject-oriented manipulate. They’re integrated unfastened, want no education for built-in and passed their 83-day built-inwalkbuiltintegrated test conveniently, so you may be assured built-in their reliability and sturdbuiltintegrated, too.

 

each models are lightweight (the Pod 1.zero, 6.2kg and the Pod three.zero, 12kg) and designed to mbuilt-inimise drag. They’re additionally vibration-free and quiet, with a maximum noise level of 60dB. wi-fi or stressed out far flung manage is available and a sun panel powers the 7fd5144c552f19a3546408d3b9cfb251 battery, although it can also be charged through a cable connection on your motor. however, boat owners can also pick a aspect mount manipulate.
