Manufacturer / model introduction

The JuiceBox series of EVSE hardware was first developed by eMotorWerks (EMW), an independent EV shop founded by Val Miftakhov, and they brought the first generation JuiceBox to market in 2013. In 2017 the company was purchased by the Italian utility company Enel, operating under the subsidiary EnerNOC, which was later rebranded as Enel X and Enel X Way. In 2024, Enel suddenly shut down their North American operations.

JuiceBox hardware models:

• original JuiceBox, funded via Kickstarter campaign in 2013; "Base" model was simple metal box; "Premium" model base was designed to look like a huge AA battery; both were available as rewards to campaign backers in either assembled form or kit form (cheaper)
• JuiceBox Classic 40 (basic 40 Amp EVSE, no connectivity / app), released 2013
• JuiceBox Pro 40 (advanced 40 Amp EVSE with connectivity / app), released 2013
• JuiceBox Pro 40 (no model name difference?), overhauled under Enel X, released in 2017
• also 32 Amp, 48A and 75A versions of the above
• JuiceBox Pro 40 Lite (same but stripped of some features)
• JuiceBox 2.00 hardware
• JuiceBox 2.01 hardware
• smartphone app Enel X Way (Apple/Android), required to make configuration changes to the stations (via Enel X cloud), for example changing the current / amperage setting
• smartphone app JuiceNet, predecessor to above that was produced by EMW, deprecated in March 2024
• JuiceRouter, a LTE-to-Wifi gateway used to connect up to 16 stations to the cloud

Oct 2024: Enel X shutdown and the race to support those abandoned customers

• Enel X shutdown news: The Verge, Electrek
• Enel X "creditor claims information" website
• ChargeLab: blog post saying they will support orphaned JuiceBox commercial charging hardware
• ChargeLab: LinkedIn post from CEO Zak LeFevre providing more details, including an Oct 11th deadline after which it might be impossible to migrate
• AmpUp: blog post saying they can take over Enel X's commercial EV hardware
• Noodoe: website section saying they can take over Enel X's commercial EV hardware
• PulseEnergy: offering same, with specific instructions on how to point the station to them
• but also note that many in the business think this ultimately won't work and that you need to start over with new hardware: LinkedIn post from Sona VP, LinkedIn post from Red-E CEO
• TMC thread on shutdown and support options
• JuiceRescue: a DIY community website set up in the shutdown aftermath; includes the juicepassproxy project on GitHub to implement the protocol on open source
• The OpenEVSE community is working on a solution that would replace just the control board; see the OpenEVSE support forums, including
  • thread: JuiceBox / ENEL X Shutting Down (includes hardware details and interface ideas for replacement control board)
  • thread: question about clamps and LEDs (hardware details on current clamps and indicator LEDs)
  • thread: Hardware retro-fit with OpenEVSE (JuiceBox hardware details including many photos of internal components)

Immediate actions for JuiceBox owners to take before Oct 11th, that can only be done via app:

• Note that this might be as early as 12:01am Oct 11th CEST (European time), since Enel is headquartered in Italy; in the USA that would be 3:01pm PT / 6:01pm ET.
• Consider disabling the Smart Charging setting. If it is enabled, your JuiceBox will only charge cars during a preset time window. Once the app is discontinued, we do not know if this setting will become permanent. Note: most EVs have TOU / time window capability built in, and can be set the car's UI or in the car's app (or both). via Kishore Devisetti on LinkedIn
• Make any desired changes to max charge amps. Double check that your station is set to match your breaker; for example, a station on a 40 Amp breaker should be set to deliver no more than 32 Amps (due to the 80% rule for continuous loads). It could be set wrong and still wroked, but only because you had an EV that could only draw a lower current. New EV could lead to blown circuit. Just sdobule check it while you still can.
• Consider disabling any charge energy limits.
• After making last change, edit OCPP server setting to null?
