A set of standardized Minimum Required Error Codes (MRECS) is proposed to address the challenges associated with custom error codes in the North American Electric Vehicle (EV) charging ecosystem. Ther proposed MRECs can be effectively used to address the challenges of custom error codes.
The ChargeX consortium recommends that the industry implement MRECs uniformly to streamline error reporting and improve diagnostics. This report is based on independent analysis of custom error codes by ChargeX, and it assigns one or more entities responsible for the resolution of each MREC. It also provides a functional classification for each error code to describe its nature.
