The C-Max Energi should take about 7 hours to charge the 7.6 kWh battery with the trickle charger provided by Ford running off 120v AC. That may be sufficient for most users and doesn’t require anything other than a 120v outlet in your garage. A J1772 Level 2 charger should take about one third that time, or roughly 2 hours. The best price I’ve seen on a J1772 Level 2 charger is the Leviton Evr-Green at Home Depot. It’s $799. I doubt if the Best Buy/Ford charger option will make financial sense but my understanding is it charges faster than the typical 3.6 kWh J1772 Level 2 charger and is available for about $1500. (The Ford site states to contact your Ford dealer for pricing. It’s possible to upgrade the Nissan Leaf trickle charger to J1772 Level 2 for less than $300 at EVSE Upgrade. This could be available for the Ford trickle charger too – check with EVSE Upgrade.) If you decide to install a 240v Level 2 charger, it makes sense to have an electrician install a 240v plug in the garage. That makes it possible to move the charger to another location.
