Re: [Electric Boats] Re: Current 48 VDC alternator/generator options

 

Actually I have found a couple options besides the one I first mentioned.  There is a fellow at Shawnee Power Systems that has a good package deal.

Also, I found an outlet for 48 volt DC portables that will work if I can survive with 2.8 K.  But they are small enough, I could install a pair with diodes and then have twin everything.  I am looking at both of these options seriously as the cost is not too much, and they are suitable for marine use, since I am using a drystack and need forced ventilation for the battery bays.  But thanks for the advise anyway.

If you want to build a DC Generator you could use:
 
The 100amp gen-head will set you back about two thousand bucks. 
 
Then you still need a marine engine to attach it to.  Your cheapest option by far would be to just buy an AC marine generator and run a couple of chargers off the AC output.
 
There would be some convention lose this way, but with the money you saved over a Packaged DC generator, you would still be ahead money wise  for decades.

Thanks a lot Myles,  But I am needing to build a genset to power what some might call a "floating Prius".  According to the Eggheads at the controller plant, I only have 20 minutes of power at theoretical full power.  The engineers at the Motor makers say I have 2-6 hours of batteries.  And the battery distributer says I will have 8-14 hours of batteries.  So to narrow it down, and if I combine what all the "intelligent folk" are telling me, I have a precise amount of 20 minutes to 14 hours of battery storage...  So with this in mind, ... I am working on a small, SIMPLE, diesel genset that will feed my flux capacitor at about 60-65% of my Mr. Fusion... Confused yet???

As for chargers:

If you're using lead-acid, consider the Genius series of chargers.

I'm using 2 of their multi-bank chargers for my 14-battery pack on my 1920 Milburn electric car ( www.evalbum.com/348 ) --- the GEN3 (delivers 10amps to 3 batteries and manages the SOC of each) and a GEN4 unit.

Genius GEN3 chargers: https://no.co/gen3

I don't use these on my nom. 42v pack on my boat though especially since my pack is lithium these days: Enerdel 10p(2p(12s(2p))) with 17.5ah cells --- 700ah @ 31-48v
