Can we predict how expensive AC only in parked/idle will be to this EV? Can you safely sleep in the car with the AC on for 6 hours? Any expected danger or risk to doing this?

The only electric vehicle that has some history using AC on battery power is the Chevy Volt. The GM-Volt forum has some postings that mention that the AC runs effectively for hours, using a few watts of power when on, with no danger at all. The onlly complaint is for heating using battery power, which has a large resistive element providing the heat, and that really cuts power. The alternative is running the gas engine which can provide heat effectively, but generates emissions.

Until GM provides final specifications (by next year) on the Chevy Bolt EV, we cannot guess the specific answer to your question about the cost. But I can easily estimate that the eletric AC compressor is more efficient than any belt-driven comressor in normal gas engine vehicles.

BTW, why should you sleep in a car for six hours?

It's also impossible to say how much it will cost you unless we know about what electricity prices in your area are. Some places have much higher electricity prices than others.

With that there's peak and off-peak prices, and over night would fall into the overnight part. Setting it on a timer for when off-peak kicks in is probably the smartest thing to do.

I would imagine that most vehicle charging happens at night anyway, so that will likely be a easy thing for most people to do.

Indeed.

That is for the most part the sort of downtime most folks have after work and all.

Even better if you have somewhere you park during the day that has a charging station.

Maybe they will try the using inverter coolant as the heat source instead of electric heat.
The heat from the inverter coolant is much less than an engine coolant, and if the EV was off, it will be cooled by the atmosphere quickly, and not give up much heat anyway.

Yup, downtime is a big one. Having had problematic vehicles that overheated and needed cooling down to continue driving... downtime can do a lot.
