When it gets warmer, not only will the fans run but the electric air conditioning compressor will run too....at varying speeds.I have a 2017 Gen2 Premier Volt which I acquired in November. I use the included destination charger each night, usual stuff. What's changed is the temperature.(April) I live in Charlotte, NC and in my garage its currently 89 degrees. I was quite surprised when I heard for the first time fans running, not the usual pin ball activity you hear now and then. I opened the hood and there are two fans running. I get that this is "by design". My question is more about, do the fans run all the time during normal charging if temp is > then x or do they come on and off as needed. Anything else to consider or just move along.. let it do its thing?
As others have said, it's normal. Our Volt is completely quiet in the winter while charging in the garage but now is starting to run the fans due to the warmer temperatures. I never checked but it's also my understanding that the car will keep the batteries "warm" too if the temperature dips below a certain threshold.I have a 2017 Gen2 Premier Volt which I acquired in November.
