ICE Breaker J1772 extension cable technical discussion

[TonyWilliams]

We don't compromise on safety, and we don't do "hot" disconnects.

The proximity arrangement we use for JLong was pioneered by our company. The way we handle this is to not have any 150 ohm resistor.

So, the 150 ohm resistor on the proximity pin of the "host" charge plug is passed through JLong to the car, uninterrupted. When the button is pressed on the host plug, 330 ohms are added in series (480 total) to signal the car to disconnect. Simple, right?

Then, we use our own 330 ohm resistor in the JLong plug, so that pressing the disconnect button at either plug (host or JLong) will trigger the 480 ohms required to indicate to the car to stop charging.

This is a good design and exactly what I did in mine. Simple electronics. Thanks Tony for describing it so simply.

Then, you'd be the first of many who copied our JLong and wired it correctly. I published the wiring almost two years ago, both on this forum and the Tesla forum, for the use of the entire EV community and the enhancement of the EV experience.

you never figured out how to limit the pilot to the max of the cable assembly, right?

We never implemented anything. We manufacture both 40 amp and 80 amp cable, therefore the former will always handle the public chargers at 30 amps and below, and the latter can be used anywhere without restriction.
