Greenest EV Charging Solution On Market Just Released

July 7th, 2015 by  

Originally published on EV Obsession.

JuiceBox Green 40 is the first electric vehicle charging solution (or EVSE) that helps an EV driver to spite greenhouse gas emissions by charging when electricity is greenest. Basically, software developed by a new nonprofit organization called WattTime scans the regional electricity grid and charges your electric vehicle when more of the electricity is being produced by cleaner sources.

Juice Box Green

eMotorWerks, “a leading manufacturer of intelligent and connected Smart[Grid] charging solutions for electric vehicles (EV),” is the other partner on this new charging solution.

“We are thrilled to offer the cleanest charging EVSE ever produced,” stated eMotorWerks founder & CEO Valery Miftakhov. “After developing the most advanced and efficient charging solutions for electric vehicles it was a natural progression to also develop the cleanest. EV drivers now have even greater choice and control over how they charge.”

Reportedly, JuiceBox Green 40 can also charge your EV faster than most EVSEs.

Here’s a bit more info on the JuiceBox Green, JuiceNet, etc:

“Combined with the power of JuiceNet™, which prioritizes time and rate of charge based on user configured profiles, the EV owner simply plugs their EV into their JuiceBox Green 40 knowing the system will do the rest. This latest version of JuiceBox highlights the ultimate flexibility of eMotorWerks’ cloud based EV Charging platform, JuiceNet, by integrating with WattTime. JuiceNet introduces the concept of software based charging profiles that can be seamlessly applied to JuiceBox stations. Full details can be found here: http://emotorwerks.com/Green

Looks good. If I were on the market for an EVSE, I very well may get this one. Thoughts from an EV drivers out there?

    Technologies like this can also help renewable energy integration onto outdated power grids. Smart Demand/Energy use management + Renewables = Future !

  • Kyle Field

    Put up solar panels / wind turbine / residential geothermal and call it a day.

  • JamesWimberley

    Many of us are waiting for integrated domotic platforms that will optimise all the
    many electric appliances of a modern household. Nobody wants to run separate apps for the charger, the a/c, the heat pump, th solar batteries, the freezer, etc. Nest and Apple, are you listening?

    we have to globally ban coal mining as it will reduce forests and make ghost town lik in australia also deplete ground water, also make simple surface mining from sand and trees waste , gus for biostove project, women can gud work home itself if we giv work in rooftop solar,vegetables children looking as growing concern in england for white girl /white boy nly

  • TedKidd

    Seriously considering Charge point’s new home system. Seems really cool and useful.

  • Rceldib

    So instead of me setting my cars to charge in the middle of the night, I should try to charge them while my solar panels are generating? I have thought about that but I have net metering and my electricity is cheapest at night. LADWP pays more if I sell back during day, but my bill is so complex with taxes and fees even me, an engineer, can’t figure it out without investing hours/days of analysis.

    • Omega Centauri

      I think you are doing it right. LA doesn’t have so much solar that it can’t figure out what to do with it. Maybe in a few years the tables will be turned, and daytime power will be almost too cheap to meter, and nighttime power dear, but not today.

      • DecksUpMySleeve

        Which will also depend on if grid battery storage integration catches on concurrently.

    • Greg Hudson

      G’Day. It can’t be ‘that’ had for someone with more than 1/2 a brain… Simply compare how much you EARN when exporting, against how much you PAY at night (I’m assuming it is cheaper). If the PAY rate is higher, then you should export all you can, and buy back during off-peak (which is exactly what I do). My export rate is 68cents/kWh my off-peak rate (after 11pm) is 12c/kWh. You can guess when the dishwasher and clothes washer get switched on… I’m in Australia BTW.

      • Rceldib

        You must have a better utility company than Los Angeles Dept of water and Power. They say my rate is 12 cents at night and 42 cents at peak but that is only June until August. Oh and there are the add on fees and taxes so the 12 cents is really double that and when I sell back at peak I don’t get the 42 cent as they add on fees. The rest of the year I pay a flat rate. So if I use the solar for myself during the day, no taxes. On top of that I will be using green power where at night I am probably supporting the natural gas powered plant.

        • Greg Hudson

          G’Day again. My power company is called RED Energy, which is the retail arm of the Snowy Mountains Hydro Electric Authority (a semi private Govt organization). As such, they produce 100% green power (which is why I chose them). I have what they call here a Premium Feed In Tariff (PFIT) rate (set by the Govt) that I have (contracted until 2025, and transferrable to the next owner of this house). When I initially signed up, the export rate was 74c/kWh (The govt ordered 66c+8c Red bonus. Red has slowly reduced the bonus to just 0.2c – but on the plus side, they have also reduced the peak rate from 34c to 31c (valid from 7am-11pm Mon-Fri). The off peak rate has gone UP slightly to 14c (as of 1 Jan 2015). The fixed DAILY charge (added on by the distributor for maintenance of power lines – which is a ripoff, because they are all underground here) is just over $1 per day. My base power use is around 500w/hour (24/7) I monitor this real time with an LCD display sitting on my desk. I am currently (as we speak) exporting 410w from my 2Kw solar array (Mid winter, sunny day at 37 degrees South of the equator). Average sun for my location is 5 hours per day. Using this data I can see in real time, what is happening on my roof, and how much power I am using, and exporting. The only thing it does not do is record the data on my PC – but the power wholesaler does this for me on a remote web site. See my power chart for all of 2014 below. Basically, I export as much as possible during the day, minimize consuming before 11pm, then maximize consumption after 11pm (when off-peak rate cuts in). Due to the PFIT, it is not economical to install batteries, because I would lose my 66c/kWh export to the grid. In your case though, if you are not earning much, it MAY pay you to install batteries & charge up during the day – then consuming at night.

      I think we are still at the point where an EV owners should charge when it is cheapest on their network. If you have net metering, and get more for the PV juice you put in during the day than you pay at night, then charging at night save you money. Go for it! If you don’t have net metering and you are give the grid almost free power from your PV then charge them. I’m sure than in a few years you will see EV charge based on flexible load. That is the cheapest charge will be if you allow the grid to have some control on when it happens. When it has extra power, say too much wind, it will charge you. Now if you are thinking of going off-grid then it is a completely different story.
      If you can pick your supplier then picking a greener supplier will, I think, have a bigger CO2 impact than using above charger.

  • Omega Centauri

    The marginal carbon intensity (amount of carbon burned for an extra increment of demand), is not equal to the average carbon intensity at the moment, but rather to the carbon intensity of whatever power plant wil be ramped up/down to meet demand changes. So it doesn’t really minimize CO2. However, it probably helps with renewables integration, as is moves demand towards those times when renewables penetration is higher, so longer term it ought to make a higher level of renewables more attractive to the utility.

    • Adrian

      Even a few hundred chargers likely isn’t going to affect marginal demand over a regional utility’s entire service area. A few thousand, yes. So a potential problem, but likely to be years down the road somewhere.

    • Ronald Brakels

      The “green time charger” will up the average electricity price recieved by renewables and lower the average price received by fossil fuel generators (at least in places where there is an electricity market) and so that is for the good of humanity. And fluffy duckanity too. Platypusanity also benefits.

      • Greg Hudson

        I thought I read somewhere (on this site) that SA FF generators had all been shut down. Initially for 6 days, but then permanently. Am I wrong in thinking this ?

        • Ronald Brakels

          The one operating coal power station in South Australia was shut down as a precaution after an explosion in a coal bunker that injured two. It’s back up an running now, but it will be shut down for good within the next 3 years. Quite possibly at the end of next summer. At that point the state will have no operating baseload generating capacity. And we’ve been there before. The coal plant shut down over winter back when we had a carbon price. Natural gas generators still operate in South Australia for some time, but we’ve great start at cutting natural gas use. All we have to do is keep it up and not let vested interests and their pet politicians get in the way.

          • Greg Hudson

            Thanks for clarifying that. I was under the impression the State ran for 6 days solely on Wind/solar and had no FF baseload generation during that time. Again, I’ve probably misread something?

          • Ronald Brakels

            Yeah, the state has produced enough electricity from wind and solar alone to meet the state’s entire demand at times, but not for six days. But the state has run for seasons at a time without any coal power and so no fossil fuel generators operating in basload mode – that is more or less continuosly. The idea that a grid needs baseload generators is a furphy. South Australia has clearly demonstrated that it’s not necessary. Once we kill the coal plant for good, then we can work on getting rid of natural gas. It may not turn out to be that difficult.

          • Rceldib

            California too. We are down to one coal powerplant and one nuclear. We were in Morro Bay and saw the huge coal plant that closed last year. The Utility is trying to sell it but no buyers. The nuke plant in San Luis Obispo I hears is due to be down for maintenance. Possibly won’t get back on line. California has so much potential for solar, wind, geothermal, hydro, tidal it is crazy to think we need to be developing fracking or any new methods of extracting oil and gas.
