Use Cases for Communication Between Plug-in Vehicles and the Utility Grid
Description / Abstract:
This SAE Information Report establishes use cases for
communication between plug-in electric vehicles and the electric
power grid, for energy transfer and other applications.
Purpose
The purpose of J2836/1™ is to document the set of use cases which must be supported by SAE Recommended Practice J2847/1, Communication Between Plug-in Vehicles and the Utility Grid.
Use Case Methodology
Each use case is described by a ‘package' comprising several components:
• Brief written description of the use case, its actors, and intended purpose.
• Scenario matrix, specifying required and optional use case attributes.
• Equipment diagram, depicting actors and physical components of the use case.
• Communication path diagram, depicting communication transports and components.
• Activity diagram, depicting the interactions among use case actors.
• Sequence diagram, depicting the sequence of message flows in the use case.
Several of these concepts – notably, actors, and the activity and sequence diagrams – derive from EPRI Intelligrid methodology, which in turn is based on Unified Modeling Language (UML)1
