Any Programable EVSE

Thu Aug 31, 2017 6:53 am

Any idea which EVSE unit is program-able or mobile controllable on time and charge rate ?
(Honestly I couldn't get my FFE value charge to work - it always charge immediately after plug in - I tried many different ways.)

I want to have some sort of control remotely on start and stop time of my charge (e.g. 3AM start and 3 hr to stop at 6AM.) to avoid over charge.
And I also want to control the rate, I want slow charge rather than typical L2 charge rate. I understand Jxxxx protocol use pulse width to tell car how much it can draw, so it should be easy.

Unfortunately, I couldn't find such product now.

eMotorWerks also has a new product (backordered) called the JuicePlug, which lets you custom configure charge rate (slowing it down) and time for any EVSE-

Can't get Ford to fix the issue? Mine was resolved by replacing the TCU.

The simple solution is to use a timer on the outlet your EVSE is plugged into or build your own EVSE with a timer. If you want remote control of charging time and current then I hope you're an EE because you will have to build and develop this yourself. There are no products on the market that can do that.

The eMotorWerks Juice Plug should do just that. Once it's in stock that is... lol

Huh, I though all the juice plug does is record the kWh put into your car and upload it's status using your wifi to emotorwerks website for you to view. Guess I was wrong... Interesting....

Some OpenEVSE equipment would have this capability. Current firmware has a remote API that can be accessed via WiFi (if installed). There is a very basic built-in web interface that allows issuing commands to the EVSE (start/stop, charge rate etc.) and I believe there is some gui development going on. I haven't played with it much but I can control the EVSE state and charge rate from a phone within WiFi range. I'm sure you could also set it up with a home network that you could access remotely. My unit doesn't have the real-time clock circuitry required for advanced scheduling but, on EVSEs with that capability, I believe those commands are also enabled in the remote API.

This unit should have all the necessary capabilities. You could also save a bit by ordering a kit instead and assembling it yourself.

I heard a rumor that eMotorWerks FINALLY got UL listing for some of their products???

That certainly is a nice, and quite attractive, EVSE. However, as far as I can tell, it will only do part of what the OP wants. Charge scheduling would not be a problem but it looks like the max current draw is NOT adjustable. On OpenEVSE units, max current is adjustable via software in 2 amp increments and this can be done remotely via wifi on appropriately equipped units. JuiceBox units have similar capability with more polished remote access/apps etc. At least the old ones did - I wonder if UL listing required limiting the adjustability of max current?
