Responsibility Classifications

This work proposes a new responsibility classification to address the ambiguity surrounding the source of errors and their resolution responsibility within the EV charging ecosystem. Each MREC is therefore split into four categories- 1. EV user, 2. CSO, 3. EVSE, and 4. EV.
