My very occasional drive from home into the Big City is about 40 miles, or just about the range of my 2015 Volt. Is there a quick rule of thumb that can tell me whether it is more cost effective to pay to charge rather than using gas on my way home? I just got my Volt and haven't used a public charging station yet. I hear that they can charge by time or by the amount of electricity used. What should I keep in mind? Such as, "If the price of gas is above X and the cost per (hour/Kwh) is below X, it's cost effective to pay for a charge."
