The minimum hardware required to upgrade the Juicebox electronics would be:
OpenEVSE Controller
GFCI coil
LED display
With Enel X Way closing their doors, you might just get more interest with this.
I bought a JuiceBox 40 this summer, this might be an interesting project. Admittedly I have not touched electronics in a while, so any pointers or ideas are definitely welcome.
There are now a choice of two direct replacement boards for Juiceboxes.
A very easy and affordable retrofit, see the OpenEVSE parts store (ALL).
This direct replacement retrofit option is great... Excellent work Chris!!!
I just bought two of the retrofit kits, one for my old juicebox and one for the juicebox that my dad bought last year.
However, I wish I knew these were being worked on when I ordered the full OpenEVSE kit a couple months ago. Then I could've just waited a bit saved myself several hundred bucks :(
Does the EVSE retrofit kit allow 48 AMPS draw on a JuiceBox 40 Pro?
The Circuit Breaker is already 60Amps.
We love the 48 Amps charging which we have on another charger and it really does translate to 20% faster charging.
So can we retrofit our JuiceBox 40 Pro with the EVSE to actually supply 48 Amps (or even 50 Amps)?
Thanks
@Ron Y White The retrofit kit will let you set it to 80A maximum, but obviously that is not a good idea. Check the relay specifications and the J1772 cable the cable is likely rated to 40A, so it would need to be replaced to support 48A. The relay may be okay.

I have an old JuiceBox Classic 40a that just died, I believe its the main control board.
I'd like to retrofit the JuiceBox with the OpenEVSE controller. What parts from the openevse store would I need to do the retrofit? (beyond the controller) I want to do a simple retrofit for now, until I get to ordering more parts for a second openevse.
One note: my Juicebox is not standard. Its been modified as I didn't want to keep the evse outdoors.
I've been using it with a tetherless outdoor Type2 outlet. with a Type2-Type1 cable for my i3 and 500e
The plan is to have a 2nd complete openevse set up to use a tetherless outlet as well.
