Can anybody recommend a good introduction/overview of electric systems on a boat for somebody that knows nothing about it? How it all works? How you know how much generating/battery capacity you need?

Thanks,

Donnie

Donnie, this is a really important question and what this website claims to be all about. We have a category devoted to "resources" and a page for "technical resources" but it is lacking in good information at the moment, I have to admit. It is near the top of my to do list to add some good resources here and really make Electric Seas a central source for general information about electric systems on boats. Please check back here in the next few weeks and you might find what you're looking for here on this website. There is a lot of good information out there but it seems to be scattered and I want to do a better job of collecting it all here. In the meantime, a lot of our members have collected some good information and have good reading lists, like Capt Mike has posted here.

A basic primer I used in building my all electric dory was "Electric Boats: The Handbook of Clean, Quiet Boating".  It's an older book but goes into a lot of detail on how to calculate power needs and battery size. It mostly discusses small electric boats but the information is easy to transfer to larger boats like I did with my 26' dory.  

 It doesn't, however,  go into any details on how to integrate it into larger mechanical systems such as diesel engines etc.  It also doesn't discuss how to integrate it with AC systems in larger boats, nor does it discuss the newer Lithium Iron phosphate batteries that could be used.  The lithium technology looks exciting but it is still  about 3 times as expensive and the standard lead-acid.  I keep hoping the prices come down so I can put into my electric pick-up truck.  I will keep the lead acids in the boat however because they provide my ballast as well.

 

You can find used copies on Amazon at a reasonable price.  I believe it is out of print so new copies are expensive.

Another good source of information on batteries in general, but only batteries, is the "battery university" web site (www.batteryuniversity.com )by the president of a company called Cadex.  You could print off their information pages and compile them into a notebook.

2015 Harbor Test Data

Posted the 2015 results of the annual Harbor Test of my Thoosa 9000 EP system. My boat is 30 feet long and 16,000 lbs with an 11 foot beam. No real surprises after eight years with EP. Still doing the happy dance that I made the conversion:http://biankablog.blogspot.com/2015/07/harbor-test-2015.htmlCapt. Mikehttp://biankablog.blogspot.comSee More

ASMO Controller--Data Logging?

I have an ASMO Thoosa 9000 system in my Ericson 30+  Does someone have a guide to pulling data out of the system?  I have heard that the controller keeps some event data.  I notice when I open the controller black box, that the big green brick inside has an RS 232 port. Is that just for programming, or can one also pull data out of it?  I've like to be able to keep a log of what's happening with the motor and battery system.  Thanks. --Ernie GalvanZenergy, Ericson 30+See More
