Smart Grid Communication
Recharging a large battery pack presents a high load on the electrical grid, but this can be scheduled for periods of reduced load or reduced electricity costs. In order to schedule the recharging, either the charging station or the vehicle can communicate with the smart grid. Some plug-in vehicles allow the vehicle operator to control recharging through a web interface or smartphone app. Furthermore, in a Vehicle-to-grid scenario the vehicle battery can supply energy to the grid at periods of peak demand. This requires additional communication between the grid, charging station, and vehicle electronics. SAE International is developing a range of standards for energy transfer to and from the grid including SAE J2847/1 "Communication between Plug-in Vehicles and the Utility Grid".

Famous quotes containing the word smart:
“Often, we expect too much [from a nanny]. We want someone like ourselves—bright, witty, responsible, loving, imaginative, patient, well-mannered, and cheerful. Also, we want her to be smart, but not so smart that she’s going to get bored in two months and leave us to go to medical school.”
—Louise Lague (20th century)
