Bunch of reponses here
Good to see that you are alive and well Evan, Diane as well, of course. I suppose the little one is no longer little. We ahve had some serious knock down drag em out parties on the Cavu.
Ya these are lithium polymer batteries, scared the **** out of me at first. The numbers are outrageous. 80 kilos, 10KWH, $20k. 12 fed ex sized gooey packs all in a nice aluminum
box. Ran the air conditiong all day long, wow. You are absolutely correct on overcharging, small meltdown occurrs, no where as resilient as lead acid.
Genset will be the limit as it is with all hybrids/ diesel
Hybrid cars work because of the opportunity for recouping power with the brakes, boats just do not work that way.
Third article from Nigel Calder has introduced a parallel system that works when needed, like cars do. His writing partner has the a patent on that system. Third article in Calder series now online.
Right you are about the term hybrid. Two types, Serial
which is no batteries and the battery
centric multiple input and output kind. Calder gets into this in this last article
AC induction genset is on the boat we just launcehed the electrical
side of the genset is tiny, 10 kilos and 12kw. Very effiecient, very new, very leading edge, very scary for boat builders.
All other argumnets aside what is really driving this issue will never be effiecency but quietness, it's liking having a sewing machine
running in your bilge
