ABOUT THE CLIENT
ChargeZone is an Indian company focused on building and operating a large network of fast-charging stations for electric vehicles (EVs), offering a comprehensive EV charging infrastructure with a mobile app that allows users to locate, book, and access charging stations across the country, aiming to facilitate the transition to electric mobility.
OVERVIEW
ChargeZone possessed the necessary hardware capabilities to serve their potential users but required a partner to develop and manage the entire backend and client-side software.
Air Canada and Aeroplan partnered with Trew Knowledge to leverage our expertise in login, registration, and privacy-by-design for global enterprise ecosystems to assist in building a system that would meet the expectations of the program and its omnichannel, fully integrated solution. A large-scale migration was required to move all the personally identifiable information (PII) and customer data securely.
RESULTS
The total app downloads rose to
The total number of charging sessions went up to
Defining Goals
ChargeZone faced significant challenges in integrating and standardizing data from multiple EV charger hardware vendors, each using unique and unreliable data formats. Expanding operations internationally, particularly to Abu Dhabi, required localization, compliance adjustments, and vendor-specific integrations. Additionally, developing a global EV charging ecosystem demanded expertise beyond traditional software development, including knowledge of electrical and automotive engineering.
1.Seamless Data Integration & Standardization
Develop a unified data framework to integrate and standardize incoming data from multiple hardware vendors, ensuring reliability and compatibility within ChargeZone’s ecosystem.
2.Scalable & Compliant Global Expansion
Adapt ChargeZone’s platform for international expansion, addressing localization needs, regulatory compliance, and seamless integration with new vendor technologies.
3.Bridging the Gap Between Software & Engineering
Equip the team with cross-disciplinary expertise in electrical and automotive engineering to optimize software solutions for real-world EV charging infrastructure challenges.
4.Ensuring Accuracy & Efficiency in Data Processing
Implement robust data validation mechanisms to ensure that all charging session data is accurately received, processed, and recorded, minimizing discrepancies and enhancing operational efficiency.
Problem statement
Integrating disparate EV charger data, ensuring compliance for global expansion, and bridging the gap between software and engineering posed major technical challenges for ChargeZone.

Approach to building the app
The development process focused on integrating OCPI-compliant data, enabling multi-tenancy for Chargecloud, and ensuring scalable performance. Backend and cloud infrastructure were optimized to support international vendors and handle real-time charger availability data.
1. OCPI Standardization & Cloud Migration
- Aggregated charger data from multiple vendors and standardized it using the OCPI protocol.
- Migrated all data from legacy systems to ChargeCloud, ensuring compatibility with modern cloud infrastructure.
- Implemented automated validation mechanisms to ensure data accuracy and consistency across platforms
2. Multi-Tenant Backend Architecture Implementation
- Shifted ChargeCloud from a single-tenant to a multi-tenant architecture to support multiple international clients with independent data structures.
- Developed tenant-specific configurations to adhere to varying compliance requirements and regional regulations.
- Reconfigured the backend to dynamically allocate resources, ensuring smooth scaling as new vendors joined the ecosystem.
3. App & API Development for Real-Time Charger Monitoring
- Built and integrated APIs to fetch real-time data on charger availability, session progress, and pricing.
- Developed mobile and web applications that displayed charger statuses, enabled bookings, and provided real-time charge monitoring.
- Implemented a queuing mechanism for real-time updates, ensuring minimal latency in reflecting charger status changes
4. Performance Optimization & Scalability Enhancements
- Conducted load testing to ensure the system could handle high concurrent requests from multiple users and vendors.
- Optimized backend processing to improve response times, reducing the time taken to fetch and display charger status.
- Introduced caching mechanisms for frequently accessed data to reduce API load and improve app performance.
The team at Beyond collaborated extensively with us and was in sync with our vision from the get-go.
