Madmax98 Posted May 14, 2015 Report Share Posted May 14, 2015 Did 'some' putzing around with the lights for a couple hours.Then drove the car in EV mode for 20 minutes.My wife may have driven in EV only mode for past 2 or 3 days.Got to destination,got out of car.closed door and heard a double honk TWO fast honks - Beep Beep.tried a few doors, all doors gave same double honk(perhaps car was still 'running'), not sure.came back out after maybe 30 minutes in store. Battery Dead, needed jump. So, question is whether A) how'd I kill the batteryandB) if it was cumulative wear on battery, is the lesson learned that owers need to drive in non-EV mode at least a few miles every week to charge the 12V battery.orC) do I have a bad battery or charging system that isn't charging the battery properly.

plus 3 golfer Posted May 14, 2015 Report Share Posted May 14, 2015 (edited) The quick, double horn honks is to alert you that the car is in ready to drive mode, you exited the vehicle with your keys, and closed the door. What I do know (for the Hybrid and I assume the Energi) is that if you leave your keys in the car in ready to drive mode and leave the car, the 12 V battery and HVB will not discharge completely as ICE will 1) start up to maintain the batteries (ICE charges HVB, HVB via DC/DC converter charges 12 V battery), 2) shut down once charged, and 3) repeat the on / off cycle until ICE runs out of fuel. Apparently, this did not work per the owner's manual: "Accessory Mode Battery Saver for Intelligent Access Keys (If Equipped)If you leave the ignition on after leaving your vehicle, it will shut off 15 minutes after you close all of the doors."

ArizonaEnergi Posted May 14, 2015 Report Share Posted May 14, 2015 (edited) The 12 volt battery is charged from the HV battery, no need to run the ICE. But only driving 20 minutes isn't going to charge it much if it had been discharged by fiddling with the lights. Don't know how you killed the battery though because if you left it running it should have been charging the 12v until it shut down automatically. A double honk means you left it running and have the fob outside the car. Many of us on the Energi forum have bought DC meters that plug into the lighter socket and can be used to check charging voltage and turned off voltage.
