OPEN SMART CHARGING PROTOCOL 2.0
OSCP 2.0 is officially released in October 2020. OCA adopted the Open Smart Charging Protocol (OSCP) in 2015. After processing the experiences from several pilot implementations of OSCP 1.0, a new, improved version 2.0 is now ready for use.
The OSCP was originally designed for communicating a prediction of the local available capacity to Charging Station Operators, to enable them to fit the charging profiles of the electrical vehicles within the boundaries of the available capacity. The new version describes use cases in which the messages are applied in more generic terms than OSCP 1.0, which was specifically aimed at smart charging of electric vehicles by a Distribution System Operator (DSO). The reason for using more generic terms is that this specification does not want to limit possibilities of the protocol to smart charging EVs. This is driven by the integration of EVs in larger energy ecosystems, including PV, stationary batteries, heat pumps and other devices. Other changes are the switch to JSON / REST, additional types of forecasts (generation, consumption, fallback) and a message for reporting errors.
