I ordered a J1772 connector from China for around $100 and got a big surprise during prototyping my EVSE circuit. I thought about using a micro-controller but realized its not really needed as I didn't have a development environment. But when I looked into the J1772 Proximity function, I...

I have designed my own EVSE but am having trouble finding a precise description of how the EV proximity detection actually works. Does anyone know what the J1772 spec or specifically the Nissan Leaf is looking for on the "proximity" pin to decide the connector is engaged. I've looked around and...

My Leaf ran out of charge and was towed home. I charged it and it refuses to go into Reverse or Drive and reports an "I-Key System Fault". Has anyone seen this and know of a solution. I tried both my electronic keys but neither makes a difference. thanks

Has anyone seen an adapter that would allow the use of the 600 AVCON charging stations in California while we are waiting for Clipper Creek to upgrade them with their grant? My understanding is that the AVCON conductive interface is compatible with the J1773 Level 2 except the connector...

I want to be able to drive from Sonoma County into San Francisco but charging stations seem to be few, far between, hard to find, risky they are not tied up and quite a problem. I've looked at the Coulumb Chargepoint, EV Project, and DOE Alternative Fueling Locator maps below and its tough to...

Has anyone experienced upon starting the Leaf, on the navigation screen, to accept or decline - over and over. I would expect to be asked once and upon accepting, it would never do it again. I'm afraid to decline for fear of creating a problem so I just keep accepting over and over. Its getting...

Has anyone seen solid details on the difficulty of replacing the Leaf battery system when the battery capacity becomes unusable. After 5 or so years, our Leaf batteries will probably have decayed to 80% or so of their original capacity. Given the 100 miles range can be limiting for some...

I'm curious among the people who feel capable of both doing wiring and building simple electronic kits, what would the interest level be in just building your own EVSE and installing it? If all of the AC path items such as the NEMA box, 240VAC GFCI, relays, and the chord/J1772 receptacle could...

I was looking over the J1772 standard I found at: http://wenku.baidu.com/view/8d35b7d049649b6648d747b5.html and it turns out the pilot signal from the EVSE to the EV charger tells the charger how much current it may try to draw. The pilot tone of 1KHz besides defining the coupler state also...

I presume San Diego did their homework in determining what a volume price should be from suppliers. They show labor = $1050 and Materials = $1137 Permit = $85 Total = $2272 Looks a bit like the Aerovironmant $2200 :lol...

Here is a nice presentation by the SAE J1772 Task Force Lead that has a simplified schematic/block diagram should you be curious: http://grouper.ieee.org/groups/earthobservationsSCC/IEEE_SAE_J1772_Update_10_02_08_Gery_Kissel.pdf

I have a Leaf reserved and received an email to set up a charger assessment which led to some confusion when I called the Nissan leaf customer service and they transferred me to AeroVironment customer service. Because of my great interest in getting a leaf, I quickly clicked on the link to set...
