Addendum re hybrid battery systems
Have done some sleuthing, understand the Prius's (maybe all..?) dance 'twixt the 12V battery (an hugely overpriced item ~$250 in Prius) and the HV battery pack. In stasis (however long) the nest of cells in HV batt are completely disconnected from the world; self-discharge is minuscule--but not zero
(thus as with all of the Li-Ion chemistry, super-long stasis Can do bad things if V drops below (x volts for Li_Ion.)
But that takes many months (and with cars which autostart and recharge both batteries, one probably need not worry about the many-months danger date, whatever exactly that calculates out to be, (via discharge rate -vs- months to reach the MIN allowable voltage-per-cell.).
Details == tmi, but the gist is: if 12V batt is near-dead then nothing works, some settings are lost, like clock etc. IF the 12V battery is too low, then the gadget cannot heal-thyself via running engine: all of which requires that main battery pack is er, viable (so it can also replenish 12V batt. {sheesh} ... its another bug-hunt aka N! sequences.
Clue then: for "too-long" disuse periods, easiest SYA is to have a *good* quality smart charger on the 12V battery, all along.
Like: my Duracell-vi-Xantrex 15 amp charger, like a lunchbox with big handle (and it's light.)
Has a cpu, digital display (checked OK via Real test eq.) and can resuscitate sometimes even badly abused Pb-acid batteries.
No hint! of a Model#, just a phone $ on Manual and www.xantrex.co_/support. Stole mine for $30 but Lists (Listed..?) for 70ish IIRC.
Chump change for maintaining exotica like these cars. This stuff is in my bailiwick and.. this is the sanest, scientifically-smart charger I've seen yet (except in labs.)
tl;dr With some basic Ohms Law and lore on battery chemistries: one Can setup an automated SYA for hybrid battery systems being stored:
is my current take-away, subject to correction (especially re specific Car Mfg. design weirdness.)
Jeez.. this shit used to be Fun, but putting "some complexity" out there to the many sci-illiterates of the dis-US ... sounds a lot like folly to moi.
Battery warranty likely covers the idiocy-caused damages; after that though: ya gots to Thimk-accurately.
Ed: Happened months ago to stumble upon a video re rebuilding a [any hybrid] battery pack/with CAUTION and some basic follow-the-steps exactly ...
(even if you barely know Ohm's Law and what-means "KW-HOURS" stored there.)
I could do this, but likely wouldn't ever need-to. And moi bloody-well Knows what a KWhr "means". It's now in my genes.
