Hi Willie, We are now a daughter company (still independent in many areas) of the energy company Enel.
When I got my kit for the silver enclosure JuiceBox from Kickstarter, I noticed that it was difficult to properly tighten the nuts with the special washers with gasket, in order to weatherproof the enclosure, so I suspect that the majority of self-built kits would not be properly weather proofed. And even if the enclosure is properly weather-proofed, there are still several ways that moisture can get in there, even through condensation out of the air – I have seen water-logged enclosures that had the most sophisticated weather proofing, but simply the fact that moist air could get in there and collecting condensation could not get out, meant that over time the circuit inside failed. This happens all over the telecom industry where you find outdoor installed enclosures for electronics – I have seen many good and bad cases in the many years I worked for a wireless company. It is a tricky field. Sometimes the simplest solutions are the best – I had great luck with an enclosure that had almost no water proofing, but was essentially just a tube closed at the top (cast in one piece of plastic) with the bottom wide open. The actual board was mounted on a plastic carrier to slide into the tube and had a bottom cover that was inserted into and went up 2 inches inside the tube. It had several holes for power and Ethernet and the locking tabs, so it would always drain out if ever water collected inside. It never did. I believe the biggest issue was bugs could collect inside and affect the operation of the (also integrated) antenna, but other than that it just had some spray-on conformal coating and that was it. Never had so few issues related to water intrusion. So, all my later designed enclosures actually had two drain holes in opposite corners. The “JuicePlug” J1772 WiFi adaptor apparently had serious setbacks. I think it did not receive the attention it deserved, but it is not dead. If I remember correctly one of the updates on Kickstarter actually indicated that there were (too) big setbacks, the first revision did not work out as expected and people were advised that they should contact the company if they did not want to wait longer. I was not in a hurry to get the JuicePlug, so I opted to wait. I believe that it is awaiting some long leadtime components and then the new revision can be tested, but I am not directly involved in that project so I have no full visibility. We should talk about CHAdeMO charging. You will be responsible for any weather-proofing as the 25kW charger that is used, is forced-air cooled. I hope this gives some background – as far as I am aware. Cor.

Seems like I've read that EMW has been bought out by somebody? I, too, started buying JuiceBoxes back in the first Kickstarted stage. I think I eventually bought three of the "Premium" versions in the half cylinder cases and, later, about three in at least two versions of the square cases. A couple of years ago, I went with the Kickstarter deal for the J1772 adapter with wifi. Your message reminded me that I'm still waiting for that one. Early on, the JBs were attractive when they could supposedly do 60 amps for ~$300 while the Tesla "Wall Connectors" cost ~$1k for 80 amps. Now, the Wall Connectors are only ~$500 while JBs have gone up in price and down in capacity. I've found JBs to be very poorly weather proofed. I've had little trouble with JBs installed in protected areas but have about three dead ones that were mounted un-protected. I think I have two dead with square cases and one dead half cylinder When an exposed JB died a year or so ago, I replaced it with a very cheap Duosida which has given me no trouble just dangling from a chain link fence. I've just mentally adapted to the reduced 16 amp charge rate or charge in a less convenient location if I need faster charging. Especially the older JBs had illegible displays and troublesome key fob controllers. Can you tell us anything of what is in the works with DC charging? At one time, I was considering trying to set up a poor man's chademo with two of the EMW products. The idea was to charge imievs at around 20kw where the AC limit is 3kw. I gave up on that idea when my JBs became so consistently troublesome. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) -------------- next part -------------- An HTML attachment was scrubbed...
