jray3, where exactly are you measuring that 12v?jray3 wrote:...I confirmed that the ACC position does not bring in the dc-dc, as my house battery (a yachting term) is resting at a measly 12.1V even after an overnight charge plus an hour of driving. With temperature correction for 50 degrees F, that's only 25% state of charge, and turning on the headlights and radio pulls it down to 11.5 V within a minute.
Yup, the inordinate cycling contributing to its demise, which is why I keep my Tesla's 12v battery on a float charger. Left to its own devices, the Tesla wakes up and recharges that 12v battery from the main pack a few times daily, depleting the main pack at about 1%/day.jray3 wrote:Teslas are notorious for a short service life on their 12V batteries due to the standby loads and continuous wireless connectivity.
Back to the i-MiEV: if I know one of the i-MiEVs won't be driven for even a couple of days, I slap a float charger onto it. Have a fused Anderson PowePole connector directly across each i-MiEVs 12v battery.
