My wife just leased a Chevy Volt. We think it makes sense to upgrade our chargers, if we can find a charger that is compatible with both cars.
The "massive charger" is a DC Quick Charge. It feeds high voltage electricity directly to the LEAF battery. The Volt is not designed to use anything like that. Both the Volt and the LEAF have chargers built in to the car which can accept either 120v AC or 240v AC electricity. Those chargers convert it to whatever voltage the battery needs.
At the end between the chargers (as defined in the previous paragraph) and the battery, the cars are different. At the end between the wall and the on-board chargers they are essentially the same. The same kinds of J1772 connectors are used to plug into the car and the same kinds of EVSEs are used between those connectors and the wall. The cars use the same voltages and can support the same amperages. You can't update the chargers inside either car, but you can use the same EVSE for both, whether mounted on the wall or built into a charging cable.
But I'm guessing that isn't what you meant when you said "upgrade our chargers". EVSEupgrade
can upgrade either or both of your portable charging cables. The EVSE specs are different, as described on their website. But the end result is that with either one you get something back that can be used to charge either car. HOWEVER, upgrading the Volt's EVSE gives you one that no longer works at 120v, only at 240v. The upgraded LEAF EVSE works at both 120v and 240v.
