Seems like about twenty minutes to me. But of course it depends on how hard the A/C is having to work and the state of your battery when you start the experiment.billvon said:I just ordered a Prius (delivery in 6-8 months) so I can't try this myself:
How long will the A/C run off the traction battery alone? i.e. how long can you sit there stopped with the engine off before the engine gets restarted to charge the battery?
