A.      Motivation

To simplify troubleshooting and increase charging reliability, the ChargeX Consortium proposes a unified methodology to define and classify a minimum required set of error codes (MRECs). All MREC messages are critical and must be supported by manufacturers. If a manufacturer’s error code matches all of the conditions of an MREC, the manufacturer can simply indicate which internal code maps to the corresponding MREC code and transmit it using the given their respective fault codes.
