How does OCPP work?
OCPP is a free open standard for EV component vendors and network operators that enables interoperability between brands. It is essentially a freely available “language” used in the electric vehicle service equipment (EVSE) industry.
Are there different versions of OCPP?
Yes. As the industry evolves, so do the protocols we use. Much like all software, OCPP goes through updates, allowing it to establish parameters for how interoperability plays into new charging station functionality (i.e., Vehicle-to-Grid communications). The most current version is OCPP 2.0, with OCPP 1.6J being its most recent predecessor.
Can any OCPP hardware work with any OCPP software?
Yes. Since both the hardware and the software are OCPP-compliant, they can be configured to work together. However, the process for integrating hardware with a new software needs to be done by the manufacturer to ensure everything is set up correctly.
Can my company join the Open Charge Alliance?
If you are a charging station service provider that makes either hardware or software, you can apply to become a member of the OCA here. There are certain benchmarks your product must meet in order to be considered compliant, but we encourage everyone in the industry to join.
