Stickler Posted Saturday at 03:12 PM Posted Saturday at 03:12 PM When sitting on the ground with only the engine master switches ON, according to the EFB, one can cause an electrical demand of 355 Watt with all consumers connected to battery and essential DC buses switched on. A 24 volt, 11 ampere hour battery should take around 44.6 minutes to fully discharge when supplying this demand. I just spent about 80 minutes on the tarmac in that condition using time acceleration and the battery was still not empty. Is battery depletion modelled?
Zabuzard Posted Saturday at 04:47 PM Posted Saturday at 04:47 PM It should be modelled and I do remember testing it explicitly a few years ago. Could you send a quick track for the setup, would be useful, thanks :)

Zabuzard Posted Monday at 05:15 PM Posted Monday at 05:15 PM Thanks for the track. This seems to indeed be a bug. Something triggers the Reset() function on the battery every ~3s. We are investigating. 2

I just watched the battery go down in time acceleration and could literally see how the in-cockpit-lighting slowly got dimmer and dimmer over time because of the reduced voltage output from the battery, until the lights eventually faded completely 3 1
