Retrofitting boats with electric propulsion is a huge market opportunity. This is already established in the automotive sector. Kudos!
Thank you for an interesting presentation.
Has "Ocean volt" ever thought about taking a 30-35 ft sailboat hull and ditching the mast, sails, winches and rigging and fitting a full length "solar roof". You could fit 15, 4OO Watt panels for a 6Kw array. In the summer Med that might give you around 30 KwHrs a day of electricity. What you end up with is a "boat for the Med". A cheap mono hull Greek Island hopper with sunshade protection and enough power for all the comforts of home such as air con, cooking, lighting, water makers and continuous 4Kt propulsion using a suitable refurbished EV battery. It would be an eye catching electric propulsion, Island hopping boating option. While the sailors struggle with sail changes in light, variable winds and get to their anchorage tired to then sleep in a hot, humid cabin the solar boat glides to it's destination at 4-5kts and everyone spends the night relaxed in a fully air conditioned cabin!
We don't refit boats ourselves, but our customers sure have thought of this before.
What’s the fuel type for the generator? Does it need water cooling like a combustion engine? How does it exhaust? How loud? What’s its fuel capacity?
how do you protect against lightning ,? MOV'S? its the biggest concern on a sailboat ,as the oceanvolt system is sort after but pricy for many and lightning would generally take out an alternator, that can be repaired or replaced at a low cost ..but I'm sure replacing oceanvolt components isnt ready available or cheap as replacing an alternator ..?
The best protection is obtained by galvanically separating as much as possible. If you install a 120/230V Transformer on your boat then it is usually the only thing that breaks, but it is really easy and cheap to replace anywhere because of Victron's excellent service network.
2.5 to 3hp of torque Being Inclusive of the Reduction of course. ( or don't say that to someone directly connecting an electric motor to a prop shaft ) The Nice Thing About Approved Systems Is They Are Approved For Their Voltages, People Out There !!!!
on the piece meal stuff:
there may be some provisions, in the emerging salt code, having to do with connections; which may allow for higher voltages than 51.2Vnom.( Not Anytime Soon Though ) but i think that center tap sea ground may have to be there, ( But Then You Have To Have Protection From EMP ) at some point; for packs over 25.6Vnom.....and the same connection code Might allow for floating packs, under those regulations, which are a little higher than 25.6Vnom.......but as it sits at the moment, electrically floating packs are still limited to 25.6Vnom
Hello, I am curious about the "Continuous Run" characteristics of the AXC 12 and 24 motor configurations.
Example: Runing for extended periods in the series hybrid configuration while the generator is online in to recharge the batteries
12 kW ja 24 kW continuous run, 15 kW and 30 kW peak for 10 minutes. The generator usually determines the motor output, because in that way the batteries do not get drained. Rule of thumb for sizing the generator is 50% of the motor power, or cruising speed.
Do you ever have plans to go with higher voltage systems or is there any benefits of having higher voltage to say 96v?
That will come for sure, as they eventually move to 400V car batteries. I think the cheapest option in the future is to get a 30-100kWh battery made for a car. Will always be cheaper than low volume 48V batteries.
i sized a system for a little Grinde 27, using one of the newer axial flux motors and got the pack down to 24V ( 25.6Vnom ).....that's the gold, because the system can still be electrically floating..
On Salt, anything over 25.6Vnom ( up to 51.2V Max nominal Li-Ion ), you really need the center tap sea ground, to center reference the pack;
but as soon as you put in a sea ground, you need faraday cages, and a way to route lightning current to sidarcs.....So don't put in CTs....but what are we going to do ???
What if I want to covert a large (60') cabin cruiser into a hybrid, but without losing top and cruising speed (22K / 17 K). It has a semi-displacement hull, so I'd like to have the power to get it up on plane.
how motor you use in leopard 40, I have one catamaran 47 feet and I`d like to change the motor to electric
