Understand the interfaces between systems.
Open charging standards make more sense when you start with the parties they connect. These resources explain protocol responsibilities, terminology, and the questions to ask before treating two implementations as interoperable.
Read the OCPP and OCPI comparison alongside the EV charging operations guide. A protocol name is a useful starting point, but implementation planning still requires confirmation of versions, features, and actual participants. Keep that compatibility check close to your architecture and integration acceptance criteria.
