I needed a way to charge my wife’s new electric car and got a quote from an electrician to install a charging station in the garage. Their quote was over $3100 including a new electric panel and increasing the electric service to the property. I did some research and figured out that a 240v outlet could be run off the existing panel with a quick change to a couple tandem breakers with no upgrade to the service (already 300 amps!). Same charging capability, and doesn’t require buying special equipment from manufacturer. $280, installed by a licensed electrician, and working great.
Lesson learned: do research before paying more than seems reasonable.
