Replacing Juicebox with NACS?

[bwilson4web]

Since 2016, I have been using Juicebox 40 Pro at home and a public location. They have fully met my expectations but eventually they will fail. Requirements for a replacement, the existing Juicebox is bold:

• NEMA 14-50 plug to grid
• NACS (Tesla) native plug
• 24 ft cable
• Wireless communication in priority order
  1. Cellular data, low rate and cheap, preferred
  2. Local Bluetooth direct to cell phone(s)
  3. Local WiFi
• Management
  • Operational health and state indicator(s) lights
  • Requires plug to be holstered before use
  • Operation status log
  • Time of day operation
  • Charge kWh limit or duration
  • Recording sessions: time, duration, kWh, optional customer or guest
  • Optional - customer or guest charge back
  • Optional - customer or guest notice of charging state

I'm surprised you don't you have one of those good-looking Tesla EVSEs. Do you use an adapter with that old Juicebox?

My first EV was a 2014 BMW i3-REx that had a J1772. That is now her car and I just have the Tesla.

To the best of my knowledge, the Tesla EVSE has no wireless communications but I need to check.

Other than the cable and connector, EVSEs should last 10+ years. They are pretty simple. The contactor switches with zero current except for ground faults. Are they dieing?
My carport EVSE is hardwired. You'll be pleased to hear I have a UMC2 with a J plug for portable use.

In the MINI Cooper SE forum @F14Scott set up two Tesla EVSEs to charge both his Tesla and SE. It sounds like the Tesla EVSEs negotiate with each other for power draw.

I have a second Tesla-to-J1772 adapter assigned for the home Juicebox. The problem is removal often leaves the adapter in the Tesla.

I'll drill a shallow hole into the side of the J1772 flange and screw in a short, self tapping metal screw to hold the two together. I'll approach it from the ground wire side incase the ground wire is close to the edge of the adapter ... problem solved.

If my Juicebox ever dies, I would be tempted to get an Emporia model, only because I already have the Emporia Vue, and their EVSE integrates more tightly with the Vue.

Recent changes by Enel-X have not impressed me at all.
