Modernization and Scalability Enhancement of Electric Vehicle Charging Platform

An EV charging service provider faces technical reliability issues with their existing application, including poor communication with charging stations, interrupted charging sessions, and unsatisfactory user experience. The current technology stack lacks scalability and a robust foundation for future international expansion, hindering business growth and customer satisfaction.

A mid-sized provider of EV charging stations aiming to expand internationally, improve operational reliability, and enhance user experience through a modernized digital platform.

• Revamp the application architecture to ensure seamless and reliable communication with charging stations.
• Increase user satisfaction and app performance metrics, aiming for an improvement from an average rating of below 3.5 to over 4.5 across platforms.
• Achieve 75% better application performance under load conditions compared to the initial version.
• Establish a dependable technological foundation suitable for international market expansion.
• Implement scalable, fault-tolerant system components to support growing user base and increased demand.
• Ensure compliance with relevant data security and privacy standards, including GDPR and ISO 15118.
• Integrate with partner networks and third-party payment processors to facilitate cross-network usage and online payments.

• Design and implement microservices architecture with dedicated services for business logic, payments, network communication, and third-party integrations.
• Develop microservice responsible for real-time data transmission from charging stations, including station status, availability, and fault detection.
• Implement secure user authentication and data encryption to meet GDPR and ISO standards.
• Integrate with external EV charging networks via APIs and protocols such as OCPI for interoperability.
• Integrate payment processing via a flexible, dynamic API platform (e.g., Stripe) to support online payments, discounts, and coupons.
• Build administrative and monitoring tools for resource management, fault detection, and scalability control.

• Integration with partner EV charging network APIs for station synchronization
• Payment gateway integration (e.g., Stripe) for online transactions
• Protocols such as OCPI for cross-network interoperability

• System scalability to support a significant increase in users and charging stations
• Fault tolerance ensuring independent service operation and minimal downtime
• High performance with a target of 75% improved application responsiveness under load
• Security measures aligned with GDPR and ISO standards, including encryption and access control
• Ease of maintenance and future expansion capabilities

This project aims to significantly enhance application reliability, leading to improved user satisfaction from an initial rating of 3.4 to over 4.7. The technical modernization will enable the client to expand into new markets smoothly, support increased user demand, and establish a scalable, secure infrastructure resilient to high loads. Achieving these improvements is expected to result in a more competitive market position and an estimated 75% better application performance, facilitating sustained growth and customer loyalty.
