For the first few weeks after I bought my Fusion Energi, I averaged one trip per day, and was able to do it all on one charge. So the 7 ½ hour charging time for a depleted battery was not an issue; I would charge the car overnight. Lately, though, my trips have been longer and/or I've made more than one trip a day, resulting in a depleted battery before going out again, or the battery being depleted before I return. A charging state costs in the neighborhood of $1,000 installed, and even with the 30% tax rebate, it's still about $700. Is it really worth it?
