The journey to settle the question
By RICHARD SCHOLER, Chair of SAE's
Hybrid Communication and
Interoperability Task Force and Manager of
Charging Systems at Stellantis.
How do we offer an immediate and simple
standardized solution for DC vehicle-togrid
and vehicle-to-home?
Buying an electric vehicle, you are
presented with myriad options and
features. One such feature is bidirectional
charging, or vehicle-to-everything (V2X)
options. Do you choose vehicle-to-load
(V2L), vehicle-to-vehicle (V2V), vehicle-togrid
(V2G), vehicle-to-home (V2H), some
combination of these, or perhaps all of
them? These features are expected to be

explained to the electric vehicle owner at
the dealerships, through their local utilities,
and by other sources.
Updating SAE J2847/2 was the first step
for DC V2G and V2H for vehicle OEMs to
offer a standard solution that multiple
OEMs and charging station suppliers can
offer and with which various vehicles and
charging stations will be interoperable. DC
V2G/V2H means the bidirectional inverter
is in the offboard charging station.
This starts with SAE J2847/2 using the
same communication code as is presently
used for DC charging. It identifies how to
apply negative signals for power and
current that are matched between the
