Hi Jay, One of your proposed solutions was: /"By default the J1772 is connected to the chargers, but if you plug 120 volts AC into the RV inlet, the relay switches the chargers over to the 120 volt side, disconnecting the J1772 inlet as a bonus."/ I did something similar to this, only using

Re: [EVDL] Two charging inlets - relay "interlock" / safety question

That would be more "elegant" and I have one of those, the Leaf OEM one, which costs $200-250 to replace if somebody steals it. A $20 extension cord is a lot less likely to be stolen, as it doesn't look "valuable". The relay and inlet and wires/connectors will cost me less than $50...and then

Re: [EVDL] Two charging inlets - relay "interlock" / safety question

Hello Jay. I have two charging inlets that is very simple to use. One is a 50 amp 4 wire 125/250 volt power receptacle and a 20 amp 3 wire 125V receptacle. The 50 amp inlet is under the hinge license plate holder and the 20 amp is under the gas inlet cover. The PFC-50 charger I

Re: [EVDL] Two charging inlets - relay "interlock" / safety question

The PFC chargers uses a 4 wire input which is RED Phase 1, Black Phase 2, White Neutral and Green ground. All four wires are use for 250/125 volts. The Black, White and Green is use for 125 volts. Unfortunately, my chargers are dual voltage and only use 3 wires, L1/N, L2, and ground, so I

Re: [EVDL] Two charging inlets - relay "interlock" / safety question

Its use would also be an ice-head familiar inlet for them to understand and use when the EV is under their care ("Yea, just keep it plugged-in to protect the battery, while you wait for the parts to come in ... [keeps pack from bricking] ). Yes, that is exactly the type of thing that I'd

Here is the specific circuit I have designed. http://s9.postimg.org/ikp4miuhb/inlet_schematic.png I would like any feedback on the above schematic. (Note that it only shows the 240 volt power from the J1227 and 120 volt power from the RV inlet, the Prox/Pilot lines from the J1227 are

Re: [EVDL] Two charging inlets - relay "interlock" / safety question

Any reason not to just use a J1772 portable charger? Lawrence > On Nov 21, 2015, at 13:57, Jay Summet via EV wrote: > > Here is the specific circuit I have designed. > > http://s9.postimg.org/ikp4miuhb/inlet_schematic.png > > I would like any feedback on the above

Re: [EVDL] Two charging inlets - relay "interlock" / safety question

If I understood correctly, your idea is similar to what I would want to do if I had a production EV> add a standard 5-15 inlet for a L1 120VAC charging ability. Those who know my EV history, see http://brucedp.150m.com/blazer/blazer020504-001.jpg image of the 6 inlets in the grill of my Blazer EV
