I have been working on trying to figure out which level 2 unit to buy?  In my garage I have a 40 amp breaker and I attached a pic of the plug.  I want to get the fastest charging time I can get using this set up?  What is the largest Amp unit I can purchase and it work with the C-Max.

I recommend clippercreek (CC): made in the USA, longer 3 yr warranty, UL listed (good for insurance purposes) and great customer service (reportedly, I've never needed).

 

That appears to be the common nema 6-20 receptacle, the same one that I use for my 20 amp CC EVSE.   I got the unwired unit, wired a 6-20 plug from Lowes to it and was in business.

If you have 40 amps available, you may want to consider getting a larger 32 amp unit if you're hooked on EV's, want to future proof for higher rate batteries, and only buy once.  It won't harm the CMAX as the car will only draw 16 amps from it.  If not, get at least a 20amp model to max out the Energi's charge rate. (pun intended).  You only want to use 80% of a circuit so a 20 amp circuit can safely handle a 16amp load so your 40amp is no problem.

So I went and did a search and here is a unit that I found was the EVSE-RS by AeroVironment and its a 32 amp, but no moatter what I buy 16 amp or 32 amp, its going to charge at the same rate?

I've been doing my own research on Level 2 chargers for the C-Max, and I think it comes down to:

a) clippercreek if you want a reliable system, but otherwise have all the charging logic and reports handled by the cars and myfordmobile website.

b) juicebox if you want an extremely intelligent system that can handle multiple vehicles and not depend on the cars internal software at all.  Slight concerns about their safety certifications, but apparently this is being taken care of.

c) Juicebox's aerovironment 32amp system if you want the juicebox in a more vendor supported form and with better testing/certification against fires/etc.

Yes, the Energi will only accept a 16 amp/3.3kwh rate that is determine by the charger hardware inside the car.  

 

All this competition is driving prices down.  My first 16amp 240v EVSE (Leviton) cost nearly $750 and was the cheapest on the market in 2012.
