Did this upgrade today: http://gm-volt.com/forum/showthread...-how-to-modify-Voltec-L1-EVSE-to-do-L1-and-L2
Turned out really well. Car charges at 12.xA @ 240V or 12/8A @ 120V. I made one small change to the protocol: I substituted a NEMA 14-50P for the L14-20P and a NEMA 14-50R for the L14-20R. Otherwise, followed the instructions.
Modded the foam block to accommodate the new hardware. Below: On the left, the new yellow cable is 14g (14/4 SOOW Yellow Portable Cord 600V UL/CSA); added a Conntek NEMA 14-50P. On the right, I cut away the foam to allow the 240V/120V adapter. The adapter is the leftover 120V cable from the EVSE after the mod mated to a NEMA 14-50R.
Below: new 14/4 cable with NEMA 14-50P.
The goal of this mod is simple: I carry the Voltec EVSE all the time; it's weakness is that it is limited to 120V/12A. This mod is effectively a simple soldering project that voids the warranty of the Voltec and...um...er...oh, so that I could charge at 240V/12.nA in a pinch. Yeah, that's the ticket.
