Introduction
Roaming Hub—a term once reserved for telecom—has taken on a powerful new role in the electric vehicle (EV) revolution. As India and the world shift towards clean mobility, one critical barrier still stands in the way of widespread EV adoption: range anxiety. This refers to the worry that a vehicle might run out of battery before reaching the next charging station. Roaming Hubs are addressing this issue head-on by offering a seamless, unified EV charging experience across multiple networks and providers.What is a Roaming Hub?
A Roaming Hub serves as a digital backbone that interlinks various Charge Point Operators (CPOs) and eMobility Service Providers (eMSPs). Instead of relying on separate apps, accounts, or RFID cards for each charging network, EV users can access all participating stations through a single interface—typically via a mobile app or platform that supports roaming. This allows for:
- Interoperability between disparate networks
- Real-time charger discovery
- Unified billing and authentication
- Optimized routing and travel planning
Why Roaming Hubs Are Essential
According to recent market data, over 60% of EV buyers hesitate due to range anxiety. Roaming Hubs aim to alleviate this by:
- Providing transparent access to all nearby chargers, regardless of the network
- Offering dynamic maps with real-time status, pricing, and connector types
- Supporting long-distance travel planning with suggested EV routes
How Pulse Energy Unifies EV Charging Networks?
India’s EV market has seen significant growth in roaming infrastructure, with Pulse Energy emerging as a standout example. Pulse launched India’s first EV roaming hub, connecting 35+ charging providers and over 13,000 chargers—including fast and slow charging options—into a single, user-friendly ecosystem.
Unified Charging with the Pulse App
The Pulse Energy app consolidates these diverse networks into an interactive map that lets users search by connector type, vehicle type, and availability. This is particularly valuable for drivers of two-wheelers, three-wheelers, and four-wheelers, each requiring different charging configurations.
Seamless Payments Across Networks
Pulse’s roaming hub simplifies the charging process: users can start, stop, and pay for sessions with a single login. Payments are handled in-app, eliminating the need for separate wallets or QR scans per provider. Behind the scenes, Pulse manages authentication and billing in compliance with OCPI 2.2.1, ensuring secure, real-time interactions across all partner networks.
Enhancing Accessibility with 'Paybox'
Pulse also introduced Paybox, a hardware terminal that enables app-less charging using UPI, cards, or FASTag. This innovation caters to drivers who prefer not to use mobile apps and brings inclusive EV access to a broader audience—particularly important in a diverse, mobile-first country like India.
Pros of Roaming Hubs
- Consolidated Access: Unified entry point to multiple charging networks.
- Real-Time Availability: Dynamic filtering and live status of charging stations.
- Reduced Range Anxiety: Reliable visibility into available chargers ensures confidence.
- Interoperability: Built on open standards like OCPP and OCPI.
- Inclusive Access: Works with both app-based and non-app (e.g., Paybox) solutions.
Technical Infrastructure
Roaming Hubs rely on open communication protocols that ensure flexibility and scalability:
- OCPP (Open Charge Point Protocol)
Manages communication between EV chargers and backend systems. - OCPI (Open Charge Point Interface)
Enables interoperability and secure data exchange between different charging networks. - UEI (Unified Energy Interface)
Supports unified discovery, reservation, and payment protocols at the national level.
Platform Spotlight:
Pulse Energy utilizes these protocols to deliver scalable integrations, enabling compatibility with new charging stations, third-party mobile apps, and even messaging services like WhatsApp.
Broader Ecosystem Impact
Roaming Hubs provide ecosystem-wide benefits:
- Fleet Operators
Gain a nationwide EV logistics framework with unified monitoring, access, and billing. - Charging Station Operators
Increase visibility and station utilization by integrating with national platforms. - Software Developers
Access APIs for rapid innovation and the development of new EV-related services.
Future of Roaming Hubs in India and Beyond
Roaming Hubs are pivotal for mass EV adoption, especially in fragmented markets like India. With initiatives such as FAME II and UEI accelerating infrastructure development:
- Roaming will become the default, not a luxury.
- Platforms focusing on open architecture, inclusive design, and user-first experiences (e.g., Pulse Energy) are leading this shift.
- The result: a seamless, ATM-like charging experience available anytime, anywhere.
Key Takeaways
