This is just one eighth of the LiFePo4 battery bank going into our new ferry, http://www.cmassets.co.uk/en/our-work/projects/current-projects/hybrid-ferries-project.html



 Cool  Cool



Just check out the voltage  norfolk

is that the ultimate 'off grid' bank or what  Grin

Boy you should see the inverters  Shocked methinks a few of those batteries may find a new home  whistlie.

Cheers, Paul

Wow - that looks expensive. 700kWH total it says. It says '2 banks'; you say that's 1/8th, which sounds like 8 racks. A bank != a rack?

Send the pics to endless sphere - they'll go potty over that lot :-)

I make that around 350,000 in batteries alone but I guess you get a good deal if you buy that that many, and prices have been falling steadily. Still maybe 200,000 though?

Excellent initiative - I hope it works nicely. Are you are going to be driving this thing (i.e is it _your_ ferry or just one of the company's ferries)?

Hi Billy,

they are quite small http://www.europeanbatteries.com/, module number EB30 4S6P only 31Kg but 12v and 270Ah we're working on the bank tomorrow Knighty so I'll take some more pictures.

Cheers, Paul

Morning Wookey,

 your maths is just about spot on I'd say  Grin Yup, it is our ferry, though that bank and all the control system is in Holland at http://imtech.com/EN/corporate and belongs to ferry number two. Ours is being launched on Monday the 17th at http://www.fergusongroup.co.uk/shipbuilding/profile.aspx and I've got an invite  bike Mind you she's still around six months off commissioning and entering service on the route.



Cheers, Paul

so... if it's a hybrid ferry...

props/thrusters etc.. will be run via electric motor...

for the power you'll need... you'll have to have a generator running all the time too ? (I'm guessing?)


so... why the need for the batteries ?  I thought most/a lot of ships these days ran generators and then electric motors for the props ? - more efficient etc.. because the engine can always be run at optimum rpm and no need for a crazy large gearbox etc... ?
(not that I really know anything about ships)

Paul,
      You must have the mother of all battery bank.I could do with one like that.No doubt your ferry will be extra busy with folks travelling back and forth but not getting off,,just wanting a tour of the battery bank,, hysteria.
     I would not mind getting up close to have a good look.

So that Paul can drag an extension lead to work with him and charge up his Ferry via the Arnish Power company...  Grin

Might need a few more powerspouts....!

Plug 'em in overnight to make use of all of Pauls excess production.   Grin

20% of the power comes from the batteries according to this;

Hi Knighty and all,

aye you're right for most of the time at least one generator will be running, but that is only a 330Kw generator suppling motors with the potential for 750Kw and it will shut down during periods of low demand. The plan is also for it to be able to run all of Sunday on batteries only (only two sailings). The 'power management system' is much like that on a good 'off rid' inverter in that it will start and stop generators as required using the batteries as storage/buffer.

I can't believe that I'm actually getting paid for this and put up in a hotel with swimming pool on the eighth floor  Shocked



today we've been learning how to replace or remove individual batteries,



just check out that 315 amp fuse.



This will be the tool for removing it



and this the method of bridging.

Sorry, gotta dash, it's time for dinner  Grin

Oh frack, I messed that post up, but you get the picture.

Paul,
I bet that is going to be weird the first time you are sailing and working in the engine room when the genny decides to shut off and it all goes quiet.
You are sure to go and check if everything is alright, in fact the almost silent engine room of an electric ship is going to be very odd.

Too true Billi,
            Its a taste of things to come and the more they do it like this the cheaper and better the batteries and control systems will become.
     Its obviously been treated seriously and can only mean improvements in the long term,, fingers crossed!
