Automotive Engineering - March 2024 - 5

TECHNOLOGY REPORT
Sarah Hipel, program manager, standards
and reliability, at the Joint Office
of Energy and Transportation, acknowledged
that the current matrix of charging
apps often required for a long EV trip
isn't ideal - and suggested that enhancing
the reach of plug-and-charge technology
may address some of the problem
- but probably not all. She said
there are " convening areas " of market
implementation that must be explored
to expedite the payment process.
" We want the charging experience to
be better than the gas-station experience, "
asserted Emily Durham, VP, Legal
and Government Affairs for charging
giant Electrify America.
Expanding collaborations
To achieve the reliability and interoperability
that replicates the liquid-fueling
infrastructure, the auto and charging
industries have embarked on a variety of
collaborations, but the session's speakers
said more - and more cohesiveness - is
necessary. Hipel said increased collaborative
effectiveness is the goal of the
Joint Office's National Charging
Experience Consortium, or ChargeX in
shorthand. Launched in May, 2023,
ChargeX is led by U.S. Dept. of Energy
National Laboratories and its expanding
membership numbers some 75 entities
that include the Detroit Three automakers,
BMW, Tesla and numerous charging
companies, including Chargepoint,
Electrify America and EVgo.
The ChargeX Consortium, Hipel said,
continues to frame its work on improving
the charging infrastructure in three
problematic aspects of the charging
experience:
* payment processing and user interface
* vehicle-charger communication
* diagnostic data sharing
" Our standard is 'charge first time,
every time,' " Hipel stressed. The Joint
BMW said its i5 is the first EV model to support
plug-and-charge protocols.
Office also manages the often-referenced
National Electric Vehicle
Infrastructure (NEVI) program charged
with spending $5 billion between 2022
and 2027 to install 500,000 public EV
chargers. The first NEVI-funded charging
