Handling 3,000 amps of charging current requires communication reliability comparable to nuclear reactor safety interlocks. This paper evaluates C-V2X PC5 for MCS.
Field measurements during 1.2 MW charging pulses show that 5.9 GHz C-V2X suffers zero packet loss despite extreme switching EMI from silicon carbide MOSFETs.
In the event of coolant loss, an unacknowledged broadcast packet trips substation breaker coils in 8 milliseconds, preventing catastrophic cable fires.
