Industry jargon

CSMS

Also called: Charging Station Management System, EV charging back office, charging back office A Charging Station Management System, or CSMS, is the backend software platform that communicates with and manages EV charging stations. CSMS is the formal term used in OCPP 2.x. OCPP 1.6 used the term Central System for the equivalent backend role. In day-to-day EV charging, Charge Point Management System (CPMS) and EV charging back office are also commonly used for the same or closely overlapping software category. “Back office” can describe a broader product suite that includes billing, tariffs, user management, roaming and reporting as well as OCPP charging-station management. A CSMS can receive charger status and meter data, authorise users, manage transactions, change configuration and issue remote commands or firmware updates. The exact capabilities depend on the OCPP version and the software implementation.
