Detailed Product Description

JuiceBox is an Open Source 15kW Level 2 EV charging station  costing 3-4x lower than currently existing EVSEs.

This product was initially successfully funded from a KickStarter campaign. The project received over 230% of the target funding amount from around 300 backers. As of May 2014, over 1,000 JuiceBoxes have been made!

The device is a full-featured J1772 charging station and supplies up to 60A 15kW to your J1772 vehicle (all production cars sold today) and operates on any voltage between 100V and 240V. This means up to 10x faster charging than from a regular household outlet. Generally, most of the newer EVs will experience at least 4-5x improvement by going to 240v with JuiceBox. See a table below for details. 

JuiceBox is built around an Arduino microcontroller and we are making both the hardware and software open source. It is small enough to be used as a mobile charger (plug in at the RV park, friend's house's dryer outlet, etc). It is faster. It is Wi-Fi ready. It is more affordable and flexible than other EVSEs available on the market today. 

We expect many JuiceBox extensions to be made available in the future - developed by our company or our JuiceBox developer community.You will be able to get the benefit of the great open source community around this product and get much more mileage out of your investment!

Finally, the JuiceBox is designed to be inherently portable. The Base version's dimensions allow you to take it everywhere and enjoy up to 15kW of charging power! There is an automatic power derating for 120V outlets so you don't have to worry about overloading your house wiring in that unfortunate event when you have to resort to 120V charging.

There are FOUR main configurations of the JuiceBox - Base Kit, Base Assembled, Premium Kit, and Premium Assembled.

How to order:

  1. Select the right JuiceBox Edition using the first drop-down menu on this page
  2. Next dropdown, select whether you want to add a standard 6-foot input cable with a 14-50P plug (also known as RV 50A) - this cable is matched to the cable glands on your JuiceBox and will work with all our adapters
  3. Next, select your desired output cable (J1772 cable). You do not need to do this if you are planning to reuse your existing charging cord's J1772 cable. 
  4. Next, select if you want WiFi added to your JuiceBox
  5. Next, select if you want any input adapters
  6. Next, select if you want a matching 14-50 outlet for your JuiceBox installation
  7. Next, select if you want a mounting bracket for your base JuiceBox
  8. Finally, select if you want a professional installation of your JuiceBox (in select areas only - see description) 
  9. Add resulting combination to the Cart

Note that the list of cars above is NOT exhaustive - JuiceBox will work with ANY production EV that uses J1772 standard.

 

Base Edition - DIY Kit

Includes a FULLY ASSEMBLED PCB WITH ARDUINO CHIP PROGRAMMED with latest firmware, all sub-components (power supply, relay), hardware (bolts, washers, lugs, cable entry lugs, etc), and matching enclosure needed to enable J1772 charging of your vehicle up to 240V 60A (output current limit is user-adjustable via a simple trimpot). No LCD screen or advanced controls.

Size: portable with ~11x7x3" waterproof enclosure. The cables are exiting from the bottom of the enclosure (from one of the small 7x3" sizes) so you will need some space below the JuiceBox to allow for cable routing.

You will need to add input and output cables - e.g., an RV plug (14-50P) with cord for input and J1772 cord for output - a variety of options are available through our store - check related products below. Or you can reuse the J1772 charging cord that you got with your EV. 

Basic assembly and safety skills required. With the fully assembled PCB, only minimal soldering required for some wire connections. Estimated assembly & testing time is 1-2 hours

 

Base Edition - Assembled 

Same functionality as our Base Kits but fully assembled & ready to go. Just add input and output cables - check related products in our store for more information for cable details. If you buy cables from us before your JuiceBox ships, we will connect them to your JuiceBox for free.
 

Premium Edition - DIY Kit

Same functionality as our Base Kits PLUS:

  1. Full energy metering with persistent storage (i.e. all energy data survives power interruption).
  2. Color LCD Screen with charging info, total $ saved by driving electric, total energy consumed, etc.
  3. Time of Day charging control - save money by charging at night without having to remember to plug in at midnight
  4. Larger, very cool-looking, unique enclosure custom-designed for the JuiceBox - with provisions for LCD screen, etc. 
  5. Remote control via a secure 4-button keyfob. Can be customized to user requirements

Just add input and output cables (see Base Kit description for details). Or you can reuse the 120V charging cord that you got with your EV.  The kits will require just basic electronics safety and assembly / soldering skills and can be assembled and tested in 2-3 hours. The PCB will ship 99% populated, with only a couple of large components still to be installed (LCD, wireless received, second current sensor).  

Size: the enclosure is a 6" diameter half-cylinder with flat backing, 16" in height. The cables are exiting from the bottom of the cylinder so you will need some space below the JuiceBox to allow for cable routing.

 

Premium Edition - Assembled

Same functionality as our Premium Kits but fully assembled & ready to go. Just add input and output cables (see related products in our store for cable details; if you buy cables from us before your JuiceBox ships, we will connect them to your JuiceBox for free)
