Ford is recalling 2012-2015 Focus Electrics, 2013-2015 Fusion and C-Max Energi vehicles. This is due to the 120V EVSE included with the vehicles doesn’t have a sensor (thermistor) in the plug to reduce the charge rate if it detects that the plug (the wall side plug) is overheating. The idea is that not all households/buildings have the capacity to handle a sustained 12 amp draw from a standard outlet. In those cases the outlet may overheat and cause a fire. By including a thermistor in the plug the EVSE can detect this situation and instruct the car to reduce the charge rate down to 8 amps. This is a nice automatic safety feature in the EVSE (at least it is in the ones that have the thermistor).
GM handles this a little differently with the Bolt: When you use the included 120V EVSE the car will default to charging at 8 amps. If you wish to charge at 12 amps you have to go into a menu setting on the car and turn on 12 amp charging. Thus it takes manual intervention on the driver’s part to charge at the higher rate (in either case charging a Bolt to full on 120V Level 1 EVSE takes a looooong time–even Chevy’s charging guide doesn’t give you a value, only says 4 miles per hour–because it would take a whopping 60 hours–2.5 days–to charge!).
The recommended home charger for the Bolt is the Level 2 EVSE which brings the charge time down to something a little more reasonable 9.5 hours or “overnight”. For my usage I’ve been charging the car overnight when it hits the 1/4 tick mark. From there to “full” takes a little bit over 6 hours.
If you’re driving one of the recalled vehicles take the EVSE back to the dealer you’ll get a new one. Drive safe everyone.
