2025 EV Charging Revolution_ Plug and Charge Protocol Unveiled.pdf

Launching in 2025, the "Plug and Charge" protocol simplifies EV charging, backed by SAE International, automakers, charging operators, and the Biden administration.

Revolution: Plug and Charge
Protocol Unveiled

2. Simplifying the Charging Experience

Today, owners of electric vehicles often have to navigate cumbersome processes
to reach charging stations, such as juggling multiple apps, accounts, and payment
systems. That will change with the new protocol: plug in your car, and the system
sorts it out.
"You just go anywhere you want, plug in, and it accounts for everything in the
cloud," said Gabe Klein, Executive Director of the Joint Office of Energy and
Transportation.

3. How Plug and Charge Works

The protocol is based on the ISO 15118 global standard for EV charging. It
enables secure communication between a vehicle and a compatible charging
station, facilitating automatic billing without apps or manual authorizations.
Tesla has already pioneered a similar system within its Supercharger network,
seamlessly integrating charging into its ecosystem. However, this universal
protocol aims to expand the concept across all automakers and third-party
charging networks.

4. Key developments of the protocol include:


Certified Trust List: A security feature that will enable seamless authentication during charging.
Roaming Capabilities: Support for interoperability between several Public Key Infrastructures
(PKIs), enhancing competition and user convenience.
A Unified Industry Effort
The initiative includes the involvement of major automobile companies like Ford, General Motors,
Tesla, Rivian, Toyota, and BMW, along with charging networks like BP Pulse, ChargePoint, and
Electrify America. It is also fully funded by the industry, in which $1.5 million has already been
contributed.
"Everybody's working hard to make this work," said Tim Weisenberger, SAE International's
project manager for emerging technologies.

5. More Than Just Charging

Beyond simplifying the charging process, the protocol opens the door to other
advanced features such as bidirectional charging. This enables the EVs to return
power to the grid and helps to stabilize energy supplies during peak demand,
further improving energy resilience.

6. A Future-Ready Vision

Industry leaders express optimism in the protocol's longevity, whatever the political
changes might be. As Klein said, "The ship has sailed, and market dynamics have
taken over.
The universal Plug and Charge protocol addresses not only technical but also
security challenges, thus representing one more important step toward general EV
adoption and a greener, more sustainable future.
