Seems like this board could support an additional j1772 with no new parts to the board.
posit1: Board already supports two dc contactors?
posit2: PP pin is connected to a pwm?
posit3: risk doesn't increase with this feature.
examples scenerios, A, B ,C.. pilot1 is PLT.. pilot2 is PP
Say controller is configured for <=32amp output for this example.
A, state: 0 cars connected.
A, contactor1, off
A, contactor2, off
A, pilot1: allows 16 amps
A, pilot2: allows 16 amps
A->B
B, car is connected to pilot1. Requests 16amp (per pilot advertisement)
B, contactor1, on
B, openevse detects amprage draw of ~16
B, pilot2 gets set to 1amp allowed.
B, pilot1 gets set to 31amp allowed.
B, contactor2, stays off
B->C
C, car gets connected to pilot2. Reqests 1amp (per pilot advertisement)
C, pilot1 gets set to 16amp allowed.
C, wait for monitored amperage to be reflected to <16amps before enabling c2.
C, pilot2 gets set to 16amp allowed.
C, contactor1, on
C, contactor2, on
In all scenarios if amperage is ever detected to be over.. cut all contactors(just like now)
The only new part needed for the kit would be a contactor and j1772 assembly. No additonal coils. second j1772 would flow through same current sensors but differnet contactor.
I assume I'm missing something safety wise.. Sorry for wasting everyones time, unless someone learns something, then I regret nothing.
Side question.. is there there a reason we wouldn't move the coils to be on the input instead of the output of the 5.5 diagram
