Re: EVSE options for 2013+ Leafs

Yes It's probably the same as my Zencar but maxes out at 16a instead of 30a.
I guess if your ok with 16a, for example if you only have a Leaf with the 3.8kw charger, saving the money might be nice. I personally like the ability to charge up to 27.5a on my Leaf and would be willing to pay the extra $100 or so it would cost. Actually I custom ordered mine directly from China and was able to get a longer cord and the input plug I wanted, all for cheaper than what Amazon wanted, but not everyone is probably comfortable ordering directly from China :)

I believe I read Juicebox is working on a way to directly connect to the EVSE with WiFi but as of now it's internet only and somehow through their servers. When someone asked what happened if their servers went down, their response was they had a very redundant system, of course no internet connection, no way to change the output current as of now. Again you can use the EVSE, you just can't change the output current from it's last setting.

I think you'll be OK with 6a, EVSEupgrade goes down to a 6a setting and I've never heard of anyone having a problem with it. I believe 6a is the lowest current allowed with the J1772 standard EVSEs use.



If you are of the smartphone generation then the JuiceBox is the way to go. Personaly I do not want to use a smart app on my phone to control my EVSE.

I build OpenEVSE units with a fifteen dollar multi function meter that stores stores KWH until reset; That works for me. I just want to walk over to the unit to read it. It really depends on your generation. I just want an EVSE that is safe and works for me. Most Chinese EVSE's fail the GFCI test since that requires a lot of skill to get it to work without falsing. Most Americal EVSE's like Clipper Creek, JuiceBox and OpenEVSE pass the required GFCI test. As far as I know it is just the Chinese units.

With Chinese parts the semiconductors cost $10 or less. The discrete parts cost around $10 or less. The +- 12V module is $10 or less. The case is around $20 the multi function meter is $15 and the PCB and display is $15 or less. Cables are the most expensive item with a 40A J1772 cable and input cable at around $200 or less. Add $20 for misc costs. It really costs little especially considering I paid nearly $360 just for the Ji772 Cable. Prices have really gone down. Chris is handicapped by the fact that his supplier uses Digikey exclusively. I scrounge parts from eBay. Yes I am cheap. Since I do it as a hobby I do not consider labor costs.
