SCHNEIDER, CEO and CTO
at ZEV Station, chair of the
SAE J2954 Wireless Power
Transfer and Alignment
Task Force.
Wireless power transfer (WPT)
following SAE J2954 enables
fully automatic wireless charging
solutions for electric vehicles and
promises highly efficient
charging (up to 93%) of electric
and plug-in-hybrid vehicles. The
missing piece of standardization
of light-duty WPT has been the
specification of an alignment
methodology which works in all
weather conditions and
environments, and ensuring it is
interoperable between many
different types of applications.
The SAE Wireless Power Transfer
and Alignment Task Force has
surveyed its members-including
vehicle automakers, TIER 1s,
OEMs, and wireless charging

suppliers-to determine a minimum common method
for alignment (fine alignment, pairing, and alignment
check) to be standardized. After a comprehensive
testing program, and background information, the
task force agreed to a common alignment method for
all public ground-side infrastructure called
" Differential Inductive Positioning System, " or DIPS
for short.
The DIPS SAE J2954 standard alignment system is
described as a low-frequency, low-intensity magnetic
field generated from the ground assembly with
multiple coils that can evaluated by the vehicle
assembly for positioning. A conformance test is done
to ensure interoperability between vehicle and
charging pad. Ground and vehicle WPT assembly
manufacturers can develop and test their systems
according to this interoperability specification. The
