somehow, still only 3 photos per post... ;)) Last one below - showing ~100A output.

Hi All - Just thought to post some updates on our CHAdeMO efforts from eMotorWerks.com. Lots of progress since our last posts in 2014 (really busy 2015 with our JuiceBox enterprise didn't leave any time for CHAdeMO updates). We now have ~20 units operating in various settings with our...

Hi All - Wanted to start a thread here to facilitate the discussion on this new product from eMotorWerks. Take a look at our JuicePlug: a Universal Smart EV Charging Adapter! Turn any EVSE into a smart charging station, enjoy world-class smartphone / web interfaces and get: - Anytime /...

Thank you for posting! We will be creating a separate thread on the forum to facilitate the discussion on this [we think ;-)] revolutionary device! val

Good question, Wayne. Assembled from UL listed parts per their conditions of acceptability, and reviewed & approved by the PG&E compliance specialists. Val.

Thanks Dennis - that's right - PG&E and other utilities have approved our UL-compliant WattBox smart energy meter for installation under the CPUC submetering pilot (CPUC = California Public Utility Commission). This was a 6-months process to get them to this point so we are pretty happy...

Hi All - The new version V8.11 of the JuiceBox EVSE is now shipping in four configurations! A large number of new features and significant improvements, including: - Revenue-grade energy meter now on board - 0.1% precision at 25C, better than 0.5% across the operating temp range! - Precise...

Thanks brinkhamer for your report. What kind of issues are you experiencing? Could you pls email us at [email protected] so we can see what we can do? thanks, Val

sorry about that, Graplr. I will check on why we did not respond. the answer to your immediate question is easy - you need to have that file in your sketch folder. That file has functions that operate on EEPROM to store / retrieve all config and energy data. You can get one from any of the...

Thanks Heinz for your kind words and for your suggestions. You are absolutely correct regarding balancing resistors. This will have to be done in the next revision of the boards. Regarding pins - after a reasonably long search, we now can finally make complete plugs with pins and all. We have...

Hi Ryan - this could be a known issue 8.7 firmware that manifests itself in rare combination of states. What I'd like you to do is replace a line in getState() function. This is what you should change it to: ------------- if(mode==1) pV=((pV-pV_min)*PWM_res+pV_min*set_duty)/set_duty...

nice thread. but Chris, then we would have to compare JuiceBox KIT and not the fully assembled unit - with everything mounted to the enclosure and connected and ready to plug in. Base Kit is $179, Premium Kit is currently off the site due to ongoing redesign of the enclosure (to make it much...

IMO unlikely. The input power seems to be limited via input current limit. In other words, regardless of the input voltage, the car seems to be cutting off at 30A - we have confirmed that on 240V and 120V input. I am fairly confident that 208V will be no different. What I am interested in is...

dsinned - thanks for your suggestions. We are happy to provide space but we will have to get volunteer gurus to help run the sessions. I don't think we can manage this just by ourselves - yet, anyway.

Thanks chadwick110! Do you have an FTDI cable? If not, get one (from us or any other DIY electronics shop - sparkfun, adafruit, etc). Once you get it, you would plug it into the programming header of your JuiceBox and connect to USB of your PC where you have installed your Arduino IDE. See page...
