Rewiring AC and HV panel – to avoid any cross talk/noise issues

Rewiring AC and HV panel – to avoid any cross talk/noise issues

vs Public charging stations – part 1. So my initial Walgreens experience gave me a false sense of security in not carrying a full complement of charging cords around, this was my undoing yesterday when three separate public chargers failed to link up correctly.

The common issue is the charger starts delivering current then goes into a fault condition, but not an explicit fault, more of a reset cycling, where the AC relays toggle on and off.

Theories: 1. GFI issue? I'm using the Manzanita which is non-isolated, I have BMS (which are known leakers) and a 40 year car… seems a likely candidate and will be first line of testing.

The only observable behavior from SB side is right before the cycle starts the proximity LED on the AVC unit starts to modulate intensity, and then connection is lost causing the reset cycle to start.

2nd theory Induction issue? So Lily's Blink charger at the house refuses to link up with SB at all, it immediately goes into a reset cycle. I started pulling wires of the panel, and even with only just the connection to the main AC relay, the charger still goes into fault. At this stage there is no connection beyond the relay contacts to the rest of system? If I can't find any potential diffs between the pack and chassis, I'll modify the layout to avoid a potential induction paths… more to come.
