This SAE Information Report J2931/7 establishes the security requirements for digital communication between Plug-In Electric Vehicles (PEV)@ the Electric Vehicle Supply Equipment (EVSE) and the utility@ ESI@ Advanced Metering Infrastructure (AMI) and/or Home Area Network (HAN). Purpose The purpose of SAE J2931/7 is to define the security requirements for the digital communications between the following: Direct wired point to point communication between PEV and EVSE as end devices This mode is required for DC Fast Charging or DC DER as defined by SAE J2847/2. This mode could also be used for smart charging@ DER operation@ or other purposes when the EVSE represents the combined PEV-EVSE to a remote entity and the PEV is completely isolated as with ISO 15118. This mode is used with SAE J3072. Direct wireless point to point communication between PEV and EVSE as end devices This mode would be used for wireless power transfer as defined by SAE J2847/6. Internet communication between PEV and a remote end device by way of the EVSE This mode would be used for smart charging (SAE J2847/1) and with onboard inverters (SAE J2847/3). This mode could also be used to engage with a customer with a wireless or wired connection to the internet. PEV engages a remote end device using telematics link This mode uses a vehicle manufacturer telematics link which exchanges information with an end device using the internet. PEV uses direct wired connection to end device or internet other than by charging port It may be possible to connect the PEV directly to the internet or end device for maintenance or other purposes which could corrupt the PEV software associated with PEV interaction with the EPS. It is possible that the PEV could use a Wi-Fi link rather than the wired connection through the EVSE to engage the HAN. For this document@ the latest version of NISTIR 7628 (Guidelines for Smart Grid Cyber Security) will serve as a reference to define and map the security requirements for the digital communications for Plug-in Electric Vehicles.
