Minimum Required Error Codes
This document defines mandatory error codes necessary for responsible operation
of EV charging infrastructure. Transport shall occur over OCPP 1.6J, and
shall leverage fields defined within the StatusNotification.req.
The substance of the messages defined herein are critical, and the format is that suggested by EVgo. If all conditions, including transmitted data, of a defined code are present within a manufacturer's own error codes it is sufficient for a manufacturer to indicate which internal code maps to the corresponding MREC code.
Motivation
To reduce MTTR of customer-facing charging problems through the improvement, and unification, of EVSE error codes.
