The Enel-X JuiceBox 40 received an excellent score of 89 points on our ChargerRater scoring system which equals 4.45 stars and finished up with a combined rating of 4.6 stars when averaged with our personal 5-star rating. We then offer our own opinion of the equipment, also on a 5-star scale, and average the two scores. The total is then converted into a 5-Star score. Points are then added or subtracted for features and performance. The ChargerRater five categories and in each category the EVSE starts out with 15 points. We'll be reviewing all of the popular EV home chargers so we've created a point-based system called the ChargerRater. If your home charger has the ability to schedule charging, you don't need to fumble with in-car scheduling, and possibly forget to set it back later. We should mention that most EVs today already have that feature built into the car, but you then have to disable it when you're using a public charger and can forget to reset the TOU schedule once you get home. You can also schedule the JuiceBox to charge your EV at a set time to coincide with time-of-use utility rates, which can save a lot of money. Dynamic LED lights show power, connectivity, and charging status. WiFi connectivity with smartphone app and online control dashboard. This makes charging two EVs at home more convenient and the chargers less expensive to install. WiFi-enabled 40-amp smart EV charging station (Level 2 EVSE) with 25-foot cable & integrated cable management. The JuiceBoxes will communicate with each other and ensure that they won't overload the circuit. This allows the user to share more than one JuiceBox on a single circuit. The JuiceBox also has a feature that few other chargers do, and that's the ability to power share between more than one JuiceBox. It also is Amazon Alexa and Google Home compatible and can participate in utility demand response programs. The JuiceBox's app lets you adjust the power the charger delivers, so you can use it on a circuit that is less than the 50-amp circuit required to deliver the full 40-amps the unit can supply to the vehicle. It has more of these features than any other charger available today. The smart charging features of the JuiceBox is really where the unit excels. We think it would be a good idea for Enel-X to offer a cold weather cable as an option in the future. For that reason, we can't recommend the JuiceBox for outdoor installations in areas where the temperatures frequently drop below freezing. The JuiceBox's cable actually performed the worst of all of the cables we've tested so far in the deep freeze test. Once a charging-session starts, you have 90 secs for the car to start drawing a charge, otherwise the Juicebox goes into some 'pause' (eventually changes to 'plugged in') mode and will remain there, not sending a charge - ever. "What did I consume in May?" Is not something you can answer.Enel-x Juicebox undergoes our cable deep freeze test Plugging in the car starts a session, and theres some delayed cloud round-trip to start one. The history won't do something as useful as grouping by month. This is mostly useless information because most of us just care that it is fully charged in the morning.Īlso, the dashboard is mostly useless. You can't tell the app, "the fiat is plugged into evse2 tonight." The only point is to show, in the app, how many miles went into the car during that charge season session. And you can't share the cars between the evses. It's not doing anything cool like storing per-car stats. The idea that you can tell the charger which car is connected is nice in theory, but obnoxious in practice. Once you get a second evse (with or without load sharing), the whole model breaks down. The charging works fine, but so does the free tesla evse. They are trying to build a smart charging solution that works with all electric vehicles. There are some notes in the forums about the security of the SSL certificate being used and how to strengthen it, and if you’re at all concerned about security then you should stick with the official app.īut you still need to send your credentials through a 3rd party to get the login token the first time.Īnd just to be clear: The EMW Juicebox does not currently ask for any Tesla login credentials. The app doesn’t send your password to the vendor or anywhere else, it just logs you in so it can do its work. If you decide to change your password at MyTesla, you’d then have to re-login at the app with these new credentials. This allows you to run the app without having to login again on all future sessions. Similar to Tesla’s official app, the security model on Remote S is reasonably secure - the app asks you for your “MyTesla” login information which it then uses to register a persistent token (cookie). Yeah that's how most shared online account login systems work, and Tesla's API can work that way:
