My suggestion will be to use a standard 4 pole locking NEMA inlet and supply the 100V pack and 12V to the vehicle, but since you won't want to have exposed pins carrying the full pack voltage, you will want to add a contactor onboard to close when the plug receives the 12V. You can use the BMS signal to open this contactor even with 12V present and your charger should switch off when the current goes to zero, so no signal needs to be sent back. Suggested wiring: - 2 pins for pack +and- (use the industry standard phase pins for this) - one standard ground pin (use the industry standard pin for that) - 12V pin, similar to "Pilot" in the J1772 (use industry standard "Neutral" pin to carry this signal) that also will allow accidental connection to a 240V extension cord with 240V AC present but since there is no 12V between ground and Neutral, the contactor will not close and the 240V AC will not connect to the pack...

That would be dangerous, there are many standard 5 conductor plugs that would be usable if it's just to make a single cable coming out of the car. I was making the assumption (bad bad) that the charger was on board and that it might be possible to add the handshake to make it J1772 compatible.

I don't want to put in in the car in order to save weight. But it does look like a J1772 port has 5 conductors. This might fit the bill. >> -Chris >> >> From: Lawrence Harris <[email protected]> >> To: Christopher Darilek <[email protected]>; Electric Vehicle Discussion List <[email protected]> >> Sent: Thursday, May 19, 2016 11:52 AM >> Subject: Re: [EVDL] Charger connector options >> >> Is your charger 110/220 volt compatible? Have you considered putting a J1772 inlet maybe where the gas cap is? There is some electronics to install behind it - a relay and a pilot signal. I suspect the hardware is for sale somewhere as I see the inlet ports are readily available for about $90 and then you could use any standard charge cable. >> >> Lawrence >> >>> On May 19, 2016, at 9:01 AM, Christopher Darilek via EV <[email protected]> wrote: >>> >>> I'm ready to upgrade my charger connector. Right now I'm using NEMA plugs on the ends of pig tails under the hood (I have to open my hood 2x a day). My charge rate is 18A @100V (reduced to not melt said plugs). I think I need 5 connections: +100V, battery ground, +12V, chassis ground, and BMS output to turn the charger Off. I'd like for the connector to be accessible without opening the hood. What do ya'll use?
