OmegaOmega, the only devices that run off the high-voltage NiMH battery are MG1 and MG2 (the motor-generators), the air-conditioning compressor, and the dc-to-dc converter that charges the 12-volt battery from the NiMH battery. That's the only way the 12-V battery gets charged, and the charging can only occur when the car is in READY mode. All other devices are powered by the 12-V battery. In ACC mode, the current drain from the 12-V battery (with all accessories off) is ~4.5 amperes, meaning that the 12-V battery would discharge in under 10 hours. In ON (but not READY) mode, the current drain is ~9.7 amperes, under which condition the 12-V battery would drain in under 5 hours. I posted these measurements in a different thread on this Newsgroup.

Stan - I think that's what I meant to imply (re-reading my post...) I assumed in accessory mode that it would use everything off of the 12v battery and eventually kill it... But if the car is in READY mode, you're parked, and no engine is running, are all devices not running off the NiMH battery? Similar to if you were parked in a running car, the devices would be running off the spin of the alternator... Does that sound correct?
In other words, sitting there in E-Mode (or on battery) while the car is on (READY) would cause drain on the NiMH batteries to the point where the ICE would kick back on to recharge the NiMH battery. OR, were you indicating that all power draws come from the 12v battery, regardless?
