This extended charging time can be a major source of frustration for EV drivers. To overcome this challenge and ensure the continued success of EV adoption, innovative solutions are crucial.

The Unified Energy Interface (UEI) emerges as a game-changer, aiming to revolutionize the way EV drivers discover, access, and utilize charging stations. Unified Energy Interface (UEI) is an open network that connects digital platforms related to energy, allowing them to interact and transact using a common language called the Beckn Protocol. The UEI creates a unified ecosystem that integrates digital energy solutions such as battery swapping, EV Charging, and more.

In this article, you will learn the role of UEI in EV Charging. Dive into the blog and learn how it is contributing to the emerging EV Market.

How UEI Works In EV Charging? 

Remember how cool it was when walkie-talkies came out and you could finally chat with your friend across the street? UEI for EV charging is work like that, but for electric cars and charging stations! It lets them communicate with each other using a special “language.” Here is how it works:

Step 1: EV Driver Makes a Request

  • Imagine you are in your electric car, ready to find a charging station.
  • You open an app on your phone that uses the UEI.
  • The app sends a message through UEI, asking nearby stations if they have any empty plugs.

Step 2: Stations Respond

  • All the charging stations within reach hear the app’s message.
  • Only stations with available plugs respond back, saying, “Hey, I Am free!”

Step 3: Choosing The Perfect Charge

  • The app gets messages from all the available stations.
  • It uses Beckn to show you information about each station, like:
    • How close it is
    • How fast its chargers are
    • How much it costs to use them

Step 4: Plugging In And Paying Up

  • Once you have chosen a station, the app uses Beckn again to connect to the station’s payment system.
  • You can pay for your charge right from your phone, just like buying something online! No more digging for cash!

Finding A Charging Station

  • What It Does: Helps you find nearby charging stations for your electric vehicle.
  • How It Works: Works like a navigation app, showing charging stations on maps.
  • Customized Search: This lets you filter stations by location and charger type (fast or standard).
  • Real-Time Info: Shows if stations are available, avoiding wasted trips.
  • Why It is Good: Makes finding charging stations easy, boosting EV adoption.

Picture planning a road trip with your electric vehicle (EV) – no longer do you need to carefully plan out charging stations in advance. With UEI, finding a charging station becomes as easy as using your preferred navigation app. UEI is compatible with various user interfaces, such as dedicated EV charging apps, navigation platforms, and even in-car dashboards. Through these interfaces, users can start a search for charging stations nearby.

The great thing about UEI in EV charging is its ability to customize your search based on specific requirements. You can narrow down results by location, ensuring you locate stations near your current position or your planned destination. Additionally, you can filter by charger type, whether you require a fast-charging station for a quick recharge or a standard charger for a longer stop. Most importantly, real-time availability information is shown, eliminating the annoyance of arriving at a station only to find it in use.

A report by McKinsey & Company [ref] indicates that easily accessible charging infrastructure is a crucial factor influencing consumer decisions when it comes to purchasing EVs. By providing a user-friendly search experience with real-time availability information, UEI can address this concern and contribute to increased EV adoption.

Streamlined Communication

  • The Beckn Gateway (BG): Sends your charging station request to operators.
  • Direct Communication: Operators reply directly, speeding up the process.
  • Efficiency: No middlemen means quicker responses and smoother service.
  • Why It Matters: Improves the EV charging experience for users.

When you initiate a search through a UEI-integrated platform. A central component called the Beckn Gateway (BG) acts as a messenger. The BG receives your request and broadcasts it securely to all registered Charge Point Operators (CPOs) in the area. These CPOs are the companies that manage and operate the charging stations.

UEI in EV Charging eliminates unnecessary intermediaries. Each CPO that receives your request can directly respond to the platform you used for your search. This direct peer-to-peer communication ensures a faster and more efficient exchange of information.

According to a report by Deloitte [ref], streamlining communication between users and CPOs is essential for optimizing the EV charging experience. UEI’s peer-to-peer approach directly addresses this need, leading to a more efficient and user-friendly process.

Making The Connection

  • Real-Time Info: Gives details like station availability and pricing.
  • Payment Integration: This may let you pay for charging directly through the app.
  • Convenience: Helps in finding, choosing, and paying for charging.
  • Pilot Programs: Some cities are already testing integrated payment systems.

Thanks to UEI in EV charging, the wait is over! You will receive real-time information about nearby charging stations directly on your chosen interface. This information includes crucial details like station availability, pricing per kilowatt-hour (kWh) of electricity, and the type of connector available (important to ensure compatibility with your EV).

Looking ahead, UEI has the potential to integrate payment methods seamlessly into the charging experience. Imagine a future where you can not only locate and choose a charging station but also pay for your electricity directly through the UEI-integrated platform. This would eliminate the need for multiple apps or accounts, creating a truly smooth and convenient charging experience.

While payment integration through UEI is not yet universally implemented, a pilot program conducted by the City of Oslo [ref] in collaboration with leading CPOs demonstrated the feasibility and benefits of such a system. As the adoption of UEI in EV charging continues to grow, we can expect to see wider integration of secure payment methods for a truly streamlined charging experience.
