JuicePlug - an $89 Universal Smart EV Charging Adapter

$50,667

303

TL;DR:

JuicePlug is a small, WiFi-connected adapter that attaches to your charging cable and transforms your existing charging station into the smartest station on the market. 

That gives you full anytime / anywhere control, saves you money (up to $800 / year from taking advantage of time-of-use tariffs and our JuicePoints rewards program), and reduce emissions from your charging.

JuicePlug requires no tools or assembly, takes 10 seconds to plug in, and is compatible with all EVs and EVSEs on the market.

You can get one for just $89 while the campaign runs ($139 pledge less $50 rebate when you sign up for our JuicePoints rewards program in California)

Detailed Version:

In the Summer of 2013, we rocked the EV industry by launching our first Kickstarter project for a smart charging station. It was a smashing success - we raised $60,000 (plus $100,000 in additional pre-orders) in 30 days and over the last 2 years our JuiceBox has become the industry benchmark for what a Smart Charging Station should look like.

To date, we have sold over 8,000 JuiceBox stations. JuiceBox is now routinely the number one best-selling and 'most-wished-for' EV charging station on Amazon.

We are thankful to the KickStarter community for your help in making this happen!

But, as great as it has been seeing almost 10,000 satisfied JuiceBox customers, it is still a far cry from our vision of helping every single EV driver worldwide to charge smart and clean. Today, that's over 1,300,000 of you!

And that's why we are launching this campaign for a truly revolutionary device - JuicePlug! 

JuicePlug is a small (but very smart!) adapter that transforms your existing EVSE into the smartest charging station on the market. You simply plug your EVSE's charging cable into JuicePlug, which then plugs into your car. Once connected, JuicePlug is able to communicate with our servers over WiFi. 

Finally, every single EV driver has a chance to bring 21st century connectivity, smartphone control, and automatic smart-grid integration to any EVSE that they might already own. 

Here's what's cool about JuicePlug:

  • Anytime / anywhere monitoring and control of your charging via our best-in-class smartphone and web interfaces. Set up Time-of-Use schedules, your maximum wiring ratings, turn your charging on and off remotely, etc.
  • Up to 10 automatic notification types that help you manage your EV charging experience. For example, JuicePlug can notify you that your car is still not plugged in by 10pm, etc.
  • Access to your charging history, cost of energy, and CO2 budget (pounds saved by driving electric, pounds saved by charging smart, and total pounds spent) 
  • Guaranteed full charge by specified time using the cleanest possible power - using award-winning smart charging algorithms from our JuiceNet platform
  • Ability to join JuicePoints, a revolutionary EV driver rewards program that pays you to plug in. With JuicePlug + JuicePoints, you can make money and win awesome prizes in your sleep.

JuicePlug is based on the technology that we've perfected through two years of JuiceBox EVSE refinements. Additionally, we have already tested all the circuits with other EVSEs. For example, our joint work with ClipperCreek - the leader in residential charging stations - produced JuiceNet-enabled ClipperCreek stations which we have been successfully deploying for months. 

Finally, we have built and thoroughly tested JuicePlug production prototypes (also shown in the video above). This confirmed full operation as a standalone adapter.

In order to complete the prototypes, we have used off-the shelf J1772 inlets and plugs. Naturally, that resulted in relatively large prototype units. As a part of this Kickstarter production run, we will be combining an inlet and a plug into a small, ~6-inch-long single-piece adapter. We already have designed the final CAD model for the production version.

The Specs:

  • Voltage: 100-270 VAC
  • Power: up to 40 Amps / 10 kW
  • Full J1772 support for compatibility with all vehicles
  • Measurement precision (current, voltage, power, energy): better than 0.5%
  • Monitoring & Control latency: less than 3 seconds for full smart-grid compatibility

We are now ready to build JuicePlug and are confident that it will revolutionize the relationship between the EVs and our electric grid. 

As our founder Val mentioned in the interview to a major Smart Grid publication in 2015, EVs can be a tremendous resource to the grid. EVs are the largest grid-connected storage type today and EV charging is the ultimate flexible load. If managed properly, EVs can reduce cost of electricity across the nation, make our grid more reliable, eliminate the need for dirty "peaker" power plants, and pave the way for much higher penetration of renewable generation. And now every one of you can do your part with your very own JuicePlug!

Now that the design has been thoroughly proven, we need your help to bring it to production. We want to make smart and clean charging as affordable as possible and that means volume manufacturing. The KickStarter campaign proceeds will be used to set up production processes, purchase materials in bulk, and commission volume builds of JuicePlug from our contract manufacturers.

We are looking forward to your participation in this campaign. Help us bring this revolutionary new product to the market and build the new energy future together!

Update 3/16: we have received a number of inquiries about pledging for multiple units from backers who have 2+ EVs, etc. It is definitely possible - please just pledge the multiple of your desired pledge level and we will have your multiple JuicePlug units ready to go.

Risks and challenges

Hardware projects are not easy. Hardware projects with software components are harder yet.

The good news is that we understand the challenges very well. Over the last 2.5 years, we have demonstrated excellent execution against such challenges as we brought the JuiceBox charging station from a KickStarter project to the leading smart charging station on the market - with 400-500 units now shipping every month. Our hardware and software have been pressure tested by thousands and thousands of users in all kinds of environments and with all kinds of vehicles.

As a result of all this work, we have existing relationships with 10+ key suppliers, 3 key contract manufacturers (all in the US), and logistics partners in China, New Zealand, and the US.

In addition to the successful EVSE projects, some other successful products our team produced include 300hp+ electric BMW 3-series, and 12 / 25 / 50kW DC charging charging systems. Each of these projects were highly complex, requiring tremendous amount of coordination and flawless execution.

Our team combines experience across all the areas required to deliver on this project. It is the best possible team to bring JuicePlug to the market. For more information, visit our About page on our website (link on the bottom of the page)
