The Open Charge Point Protocol (OCPP) is an open standard protocol used by electric vehicle charging station management systems to communicate with connected EV charge points, enabling remote diagnostics and secure data exchange. The three key players in the field of EV charging - EVSE Manufacturers, CSMS Software Providers, and Charge Point Operators (CPOs) - need to cooperate well for a great end-user charging experience. OCPP ensures compatibility across different systems, allowing for more choice in hardware and software for consumers and businesses. It facilitates communication between chargers from different manufacturers and charging station management systems from different software providers, enabling features such as remote diagnostics and firmware updates. To access OCPP-compliant chargers over the internet, charge point operators need reliable connectivity, which can be achieved through public wireless networks. However, OCPP has limitations in terms of remotely accessing and updating chargers, prompting companies like Twilio to offer solutions like Super SIM and Microvisor that provide advanced cellular deployment options and remote device access.
