After five years, a new and improved version of the Open Smart Charging Protocol (OSCP) is now available. After processing the experiences from several pilot implementations of OSCP 1.0, some Open Charge Alliance members requested to broaden the protocol scope to serve more wishes than just smart charging electric vehicles from a DSO perspective.
The OSCP was originally designed for communicating a prediction of the local available capacity to Charging Station Operators (CSO), 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.
Lonneke Driessen, director of the Open Charge Alliance: “We are very happy to present this new and improved version of OSCP. We are looking at a future in which electricity will cease to be a one-way street. We will have large appliances in and near our homes that will use energy and others that will provide or store it. OSCP 2.0 will help implementing this new flexible demand for electricity.”
