Systems and methods for single channel fault encoding for inverter for electric vehicle

A method comprising:

• detecting, by a point-of-use controller for an inverter for an electric vehicle, a fault;
• determining, by the point-of-use controller, a fault type of the detected fault from among n fault types;
• determining, by the point-of-use controller, a fault response group to which the determined fault type belongs from among m fault response groups;
• encoding, by the point-of-use controller, the determined fault response group;
• and
• transmitting, by the point-of-use controller, the encoded fault response group via a communication interface to a phase controller for the inverter for the electric vehicle.

A method for communication between a point-of-use controller for an inverter for an electric vehicle and a phase controller for the inverter for the electric vehicle, the method comprising:

• receiving, by the phase controller, an encoded fault response group from the point-of-use controller via a communication interface;
• determining, by the phase controller, the fault response group from among m fault response groups;
• decoding, by the phase controller, the determined fault response group;
• and
• outputting, by the phase controller, the decoded fault response group.
