When we did our taxes this year, we got the vehicle credit no problem, and a credit for our solar panel installation, but even though we filled out the form for the EVSE (TurboTax), it kept calculating our credit as zero. Since we only spent about $900 for the unit and bits to install (did it ourselves), we didn't worry too much about it. With the size of the refund, the extra $300 didn't seem like a big deal to worry about, but we couldn't ever figure out why it wasn't giving us the credit...
If you care to see why, go to turbo tax, and look at the forms view. bring up form 8911. double click on the value in line 17 and that will bring up the form 6251. Walk through the math they did on 6251 and 8911 and you'll see what happened.
I suspect you had the same issue I had. I put solar hot water in during 2011. as such I took the 30% credit for that - a nice chuck of change, thanks everybody!. However, the EVSE credit can't make your tax bill drop below the TMT (tentative minimum tax, I believe). so, as the energy credit (or the EV credit, if you had a 2011 purchase) will typically drop you below the line. So, only way to get the EVSE credit is not have any other major credit that year....
