We went thru Hurricane Irma and lost Electric for 2 nights....had it gone a 3rd night, we seriously considered sleeping in the C-Max with the AC running/Garage door up. I do wonder how often in a segment of 1 hr the ICE would have kicked in to charge the Battery...and how long the ICE would have run to charge the batteries. May sound a little out there but there was no way we were leaving our Home unprotected....after the storm and all homes and streets in total darkness.

I've thought about doing the same thing for a night out camping. I think the ratio of ON to OFF time would be small.

I will guaranty that it would kill your MPG's.

Oh no - now I won't get any sleep thinking about that! Back to a tent!

Sorry, I didn't mean to do that. Do what you got to do.

To answer the OP's question: it depends on conditions - ambient temperature, humidity, set point temperature, blower speed, whether the radiator fan runs (to get airflow through condenser).
Based on likely hotter but less humid conditons and daytime sun when we'd leave our dog in a locked car for an hour or so with the AC on, I'd say ICE will start between 2-4 times an hour for just a few minutes each time ICE starts. You will only be using about 15% of the HVB capacity during the charge / discharge cycle. I don't know of any way you can force a higher use of the HVB (charge to a higher State Of Charge) as the algorithms won't run ICE just to increase SOC much past 50% when there is no driving load demands to be met.
Also, just so you know, the battery display symbol does not show actual SOC of the HVB but the "usable range" of SOC - between about 30% and 70% when the very tip of the symbol shows filled.
