Hi Everyone,

First time in this forum. nice to meet you all and thanks ahead for your help.
I've just both my first used Chevy Volt 2013 yesterday, I charged the battery to full, It worked great yesterday.
Today, at 7:30 AM the battery was full after a long night charging. I ran the car and saw that the Energy Flow indicated "Engine and Battery Power". Is it normal? what are the condition of that scenario happens? My understanding is the battery is used first until It's empty then the Engine (fuel) takes its place. Note that the temperature outside was very cold 12F (-11C). Thank you for your explanation.

Below 35F (or 15F, depending on the settings in the center console menu,) the car runs the engine to generate heat for the cabin. If you search on ERDTT (the DIC should show "Engine Running Due To Temperature" while it is happening,) you'll find a bunch of threads discussing this, including some where folks have developed workarounds to prevent it from happening.

So yes, it's normal.

Some situations where gas engine will run even when battery has sufficient charge

EMM : Engine Maintenance Mode. Gas Engine runs once every 6 weeks of non-use, for a few minutes and runs a specific program to ensure all components are working as intended. Refer to owner manual for more info.

FMM : Fuel Maintenance Mode. Gas Engine runs if average age of gas is detected to be more than a year. Refer to owner manual for more info.

ERDTT: Engine Running Due To Tempature. For a 2013, this can be set at 35F (default setting) or 15F. Refer to owner manual for more info.

Boot not latched: If the boot is not latched correctly, engine will start when car is turned on. Close boot correctly. Refer to owner manual for more info. DO NOT press on the boot as it is made of aluminium and dents easily.

Then there is Hold and Mountain Mode, which are user initiated.

Boot?? My Volt is an American. It has a hood and a trunk lid. If you are speaking 'European' then I think you meant 'Bonnet'. :)

My experience with ERDTT is it uses very little gas and aside from having lots of heat it helps pad the battery life a little bit. My range on ERDTT was similar to a warm day with no accessories on, and I wasn't driving easy either.

Keep plugging in, run the heat on comfort and let the car do it's thing. The little bit of gas used is well worth the range and heat.
