2011 Chevrolet Volt: Full House
April 05, 2011
Now that a 2011 Nissan Leaf has joined our long-term fleet, it has created a small impact on our long-term 2011 Chevy Volt.
We purchased a Coulomb Chargepoint CT2103 charger with the expectation that it could handle two EV vehicles. And it does. Our Coulomb charger supports simultaneous charging of one Level II (240VAC @ 32A) Electric Vehicle and one Level I (120VAC @ 16A) EV (or Plug-in Hybrid EV, PHEV).
Our Nissan Leaf requires a charging time (full charge from depletion) of 8 hrs on Level II and 21 hrs for Level I. The Volt, in contrast, needs only 4 hrs on 240V and 10-12 hrs on 120V.
Because Level I charging takes so long for the Leaf, it generally gets priority on the stronger Level II charger. That leaves the 120V charger for the Volt. And if the Volt's battery is depleted -- as it was over the weekend -- it results in that 10-12 hr charge to full or a incompletely charged battery. I got the latter last night.
So we may have to allow the Volt to remain parked for the night here and there to get fully charged, or re-visit our charging priorities.
All of this probably won't apply to a Volt owner, unless she, too, has another EV.
But maybe that's our future.
