An email to k,
Been reading a number of things on the Internet… You know everything on the Internet is true, don’t you?
I am writing this as more of a way to pull things together and give me a document to refer to later.
Very cool stuff… I have come to a number of conclusions based on what I have read so far. Many I could explain, if I had the time and if you were really interested, but not needed at this point.
In my current (Roadtrek) situation… I can expect that the batteries in the Roadtrek are bad. I promise you, they are. With that said, and in a proper “timely” manner, I need to look at the best solution to acquire new batteries. This opens the gambit for a number of different battery ideas. But cost / benefit ratio of each needs to be considered. That is still an unknown.
But before spending all those high dollars on the best batteries I need to learn how “NOT” to destroy them. What I have learned so far, but still need additional information on is the proper process of restoring power back to the battery. Please see
http://www.mrsharkey.com/busbarn/electrics/chapt3.htm
The chapter talks about the three preferred stages of restoring power to a battery: bulk, absorption, and float.
I believe these different stages are very important (as proven) to the longevity of the battery. My thought is that the battery has the proper way it needs to be managed, regardless of “how” it is replenished. A separate piece of the puzzle. Getting a device (which I expect is out there but I have not yet searched for it) that would monitor the “needs” of the battery at any given time and in turn “replenish” the “need” appropriately is what I plan to search for next.
Another point that was brought up was that the batteries work well when they are quickly recharged after use.
Another point was that all batteries in a system be of a similar type and age.
There is also a number of “manual maintenance” things that need to be done on a regular basis to the batteries. I probably need an iPhone app to remind me of all the things that need to be done and when. lol.
Secondly. where is the power going to come from?
For that, each of us would need to look at how “we” would be “living the RV life”? Where will we most likely get our “Power fix”.
On a side note, I thought why can’t I add a small wind turbine to the side / top of the van (not a big one. Maybe multiples) and generate power (to send to the battery when needed) from that. Would the drag on the van, lowering gas mileage, be greater than the benefit received from the additional storage gained? Rhetorical question.
Solar, Wind, Shore power, Engine alternator, and Generator are most of the common sources I can think of. Solar and Wind are inconsistent and not reliable forms of energy. However, they fit the “batteries” (absorption, and float) needs very well. A generator is far to in-efficient to be run to simply recharge batteries. The van’s alternator are not designed to charge House (deep cycle) batteries correctly, but I believe the alternator current could be “channeled” appropriately. The same with shore power (when available) could be “managed” to best fit the batteries needs.
So I have learned more… but still have a number of questions.
