Will the upgraded EVSE work with the Chevy Volt?
This used to be problematic, due to picky timing on the Volt's SAE J1772 Charging interface, but GM has since corrected this with a software upgrade in the Volt. If you have had the dealer installed upgrade, your Volt is now compatibile with our upgrade! All recent Volts are delivered with this installed from the factory now. Our unit will now properly charge a Volt at 120 or 240 volts, and in addition it is built much more ruggedly and heavier-duty than the original Voltec unit. Our unit is equipped with 12awg cable whereas the Voltec only has 16awg! (same size as standard lamp cord!)
Are you also offering an upgrade for the Chevy Volt EVSE (Voltec)?
No, we don't feel this is a safe or viable option. We recommend our upgraded Nissan EVSE to Volt owners, as is much more rugged and better built than the Voltec unit, and in addition is more efficient. The Voltec is equipped with #16 AWG cable throughout, while the Nissan/Panasonic unit uses #12 AWG. We do not feel the Voltec unit is reliable and safe enough, and in addition, the Voltec unit is ultrasonically welded together, so it is difficult to open without damage.
