SAE International has published the first in a series of five standards addressing utility programmes for plug-in electric vehicles.

SAE announces standards for EV charging couplers

Exclusive interview with the CEO of Aker Wade: “Standardisation is the key”

Japan takes the lead in standardising EV charging stations

EU utilities pledge standardisation of EV charging infrastructure

Utility programmes will allow electric vehicle (EV) owners to charge their vehicles at lowest cost during off-peak hours. It will also enable utilities to better manage the grids during peak hours and minimise the impact of increased electricity demand that EVs will entail on the grid.

SAE standard J2836/1 ‘Use Cases for Communication between Plug-In Vehicles and the Utility Grid’:

Establishes use cases for two-way communication between EVs and the electric power grid, for energy transfer and other applications

Provides a set of communication requirements for use with various load management and rate programmes that will be established by utility companies regarding EV charging

Upcoming SAE standards

The rest of the standards in the series will include:

J2836/2: Use Cases for Communication between Plug-in Vehicles and the Supply Equipment
J2836/3: Use Cases for Communication between Plug-in Vehicles and the Utility Grid for Reverse Power Flow
J2836/4: Use Cases for Diagnostic Communication for Plug-in Vehicles
J2836/5: Use Cases for Communication between Plug-in Vehicles and their customers
