The future right there!! Light outboards, batteries getting lighter less than full tank of fuel, and can do many hours on one charge - this plus solar recharge. Imagine clipping your boat on car or untying launch from berth knowing you have full tanks for free, huge range and better performance.

I can't see (or don't understand) data regarding (a) power output and (b) hours available on full charge. How does this pan out for say 60 HP motor? What would battery weight and hours/mileage on a full charge be? If I was repowering electric would be really attractive option. If $$$ sensible. |

Its all BS. The motor weighs 150kg, they conveniently don't mention the space, the weight and the cost of the batteries you'll need. The energy density of batteries is so low that there is no practical solution for electric engines in boats other than little tenders. Even hybrid things like the Greenline 40 will do about 4 knots on electric for about 3 hours so a range of 12NM going at a crawl. So essentially useless for anything other than niche uses like a river boat. Just for fun let's do some quick math on the 150hp outboard. It is 90kW nominal so at cruise it will deplete a 90KWh battery in an hour. The 85kwh battery pack in a Tesla weighs 540kg. So you have a powertrain weighing 700kg plus. You have an endurance of 1 hour at cruise (imagine this engine on say a Haines Hunter SF600 maybe 25knots at its nominal power). So you have an engine that: - Weighs 700kg (the full weight all the time) - Goes about 25NM and then is completed depleted at planing cruise speeds. - Will then take 2 -10 hours to charge and obviously can't be done on the water - Based on the current premiums of tender electric motors vs outboard will costs 2.5-3x the price of a petrol outboard. So in summary, not for me.

WS number crunching is on to it... Based o WS number etc which look pretty much well thought thru and correct.... Around the 25kn (28mph well powered) But...that is for around a 200 hp and normal engine/fuel weight. Now add the difference in weight between a normal engine setup and the electric setup to the gross weight on the water, then suddenly the power requirements (and weight of the electric system becomes far bigger. Or stay at the std well powered 200/225hp and the cruise speed and hole shot falls away dramatically. It will take around 85 to 90hp (approx 70kw) of the 200hp engine to cruise at 28 mph. Add another 700kg to the boat weight, you now need approx 130hp to cruise at 28mph.... note: the extra weight will drop the hulls friction constant down an estimated 5 to 7 points in the calculations. Now this is all well and good on flat water, get a bit of chop the HP requirement for standard engine is around 10 to 15%...min So now to be practical looking around 150hp 115Kw min at cruise. Now the battery..A 14kwh tesla only has approx 5kw max output. now things move in to the nah... Now throw in battery plus equipment gets up around the 15K, and you need 115/5 = number batteries.. Thu apply to something like a displacement type hull and used as a tug boat, or a river cruise boat...not a planing hull. Or foil as mentioned above...??? |

Coastguard?, Can you bring me out a charged battery please... Mines gone flat.... And if you are away for a week with now mains power, your boat will go flat.... Planing boats are horribly power hungry, it takes 50l to move my 2t boat 100km, my 2.5t patrol takes about 12l to move the same distance at twice the speed. So we talk of displacement speed being more economical, it's not. It just requires less HP at a given moment. ------------- you can't fix an idiot with duct tape, but it does muffle them for a while... |

Anyone actually looked into installing a battery charger? The cost? We have installed solar panels on house roof...and was looking at cars to upgrade the wifes big horn..which included EV / hybrids. Part of that included the calculations to re charge, time, cost, and cost to install a charge point. Things got to.... batteries have about 10yr life span when storage drops below 80% (think was).. it is not use dependent. And got to $3k for charge point and had not finished fully costing it up... So we talk of displacement speed being more economical, it's not. It just requires less HP at a given moment. Displacement is a whole very different kettle of fish.. longer the hull the faster it goes and requires less hp. Rather simplified Which is why the larger planing trailer boats trawling out wide, as a displacement hull, do so on a oily rag... and the smaller 5/6m chew thru And we have so many threads questioning "why does 'joes' boat only use x fuel and my little boat uses way more?" It also explains why the little 'clip on" electric outboards can have suck little batteries.. maybe a planing hull but at trolling/ slow, or just postion in a current they are displacement hulls. |

I am curious as to what happens to the EV batteries when stuffed. Is the manufacturer compelled to take them back? Do they go back to japan? At whose cost? And what do they do with them then ? How much material is recoverable? The rare earths used in many of the later Gen batteries are horrendous in terms of the mining activity to extract them. Alan ------------- Legasea Legend member |

The battery can be repurposed to provide household power from solar charging or they can be reconditioned, the individual faulty cells can be identified and replaced. Old EV batteries are sort after.. NZ has problems as it is difficult (impossible) to get replacement batteries (for leafs) as they don't like sending them here as freight..

Does the above mean the manufacturer has any obligation to take them back? Or are we left to find a home for them? Re purposing stuffed EV batteries for solar would have limited appeal I think. Solar systems place considerable load on battery supply. Which is why solar batteries are the main cost of the system. What do we ultimately do with them when they don't function well enough for solar? High quality dedicated solar batteries have a life of around 10-15 yrs if run within strict load/maintenance requirements . Stuffed EV batteries would have a very short life as solar batteries I would think. Just wondering what the end of life plan is for them. We will have plenty if we go 'green' energy. I know it is a new lease of life for mining companies like Rio Tinto. They are trying to predict which way the battery technology/chemistry will jump, so they can gear up for the mining demand.

The Leaf is a poor design with an air cooled battery so has weak thermal management. Battery life suffers as a result. Nissan will sell you a new one for way more than the car is worth. Just browse trademe to see cars with only 60% state of charge left after just 40,000km Their value is equal only to what a battery costs. If you are green the waste of materials should put you right off. Yes if you buy a Porsche taycan you’ll get amazing performance and build quality or a Tesla (great performance without the build quality) but these are premium vehicles are well outside consideration of the majority. The issues with energy density, cost per kWh, environmental impact of making and disposing of batteries and reduction of useful life are considerable in a car and much much worse in a boat. Maybe one day there will be a better solution but it is almost certain to not be Li ion tech which we have had since the 90s. Contrary to the hype there has been very little progress in battery technology in recent years. We are left with needing a large, bulky, heavy and expensive battery to compete with ICE vehicles that take a long time to charge and degrade constantly from the day you get them. |

So I am coming to the conclusion there is no long term system in place to deal with dead EV batteries. And the 'green' solution is to electrify our vehicle fleet. Apart from where the extra charging power may come from, we seem to be heading towards a large collection of dead batteries and defunct vehicles. So ,back to topic, I can't see E powered boats making much headway either - other than very niche applications -eg MinKota, The energy equations are so unfavourable - as pointed out, plus all the other issues associated with electric vehicles. You might ask ... why? A lot of the greenwashing is basically smoke and mirrors. Passing on other environmental issues to someone else's backyard. I am a fan of solar power (have a house totally off grid), but there are real environmental issues around a lot of the proposed solutions. Alan ------------- Legasea Legend member |

Hi Alan, Your right to be wary of electric tech. I was a big fan. But the cost of the batteries in making and disposing displaces there value if you give a long term **** about anything. I don't have the answers but I do recognise the limitations in many areas of electric tech. I'm still looking and waiting to see the hydrogen tech and its overall consequences. I take the view now to look at the beginning of all vehicles, from the mining or development of raw materials for construction. To their manufacturing footprint through to there real time use and final end date. It's not simple, it's contrived unless you evaluate its core components through time. Still looking. Interesting stuff. ------------- Just cruising in my now sweetas pimped out Southern 755 HT0! |

This development will be good for getting the cost down but the batteries will weigh more than Li-ion (Na weighs 3x Li) and offer the same energy density limitations so not very good for a non displacement boat. Better for trucks and buses and perhaps cars. As an aside also the talk about fast charging is a bit of dilemma as faster charging is associated with lower battery life. That’s why your iPhone tries to work out what time you normally wake up and trickle charge as much as possible while you sleep.

My point being you are cherry picking the info. They don’t say how long you can go 30 knots but I’d estimate 20 miles and you’d be dead in the water. Conclusion. Electric boats are a niche product for hull speed use.

my feelings is that electric boat propulsion currently makes most sense for dinghies - essentially on a small scale and for short run times. if i had a need for dinghy - less than a tender to a yacht - just to do the ship-shore-ship trip i think a battery elec outboard would be high on the list i like the 'minimalism' of this; http://www.electricpaddle.com/ep-carry-dinghy-electric-outboard-motor.phtml" rel="nofollow - http://www.electricpaddle.com/ep-carry-dinghy-electric-outboard-motor.phtml

Hmm. There is a big push for EV cars in NZ. There is an EV Association - forget their name. They have an aim of something like 20,000+ more EVs on the road in next 2-3 yrs. All good so far. (of course they want to sell plenty) Then the Q of how we charge them all (Rio tinto is back on). I asked them last yr what the plan was for all the dead batteries (not an easy solution as far as I know). No answer. Hmm. So I asked Julianne Denter - who was also prooting the idea - green answer to FF. What I got was basically, we will sort it later. Can you see the problem? You would think if this was a policy to solve an environmental problem, the pending environmental issues of the solution would already be addressed? Then there is the mining footprint (and CO2) for the rare earths used in a lot of the battery technology. Tonnes of earth mined for gms of earth. My money is still on hydrogen - I posted on this a yr or so ago. Alan ------------- Legasea Legend member |
