An EV Charging Station Rental App for B2B and B2C

The idea of the product revolves around the need to monetize the hardware of EV charging stations. Firstly, it’s an offering for corporate fleets, and then it serves as a rental app for retail clients. In both cases, software was called for seamless communication and reporting through secure financial transactions, real-time data tracking, and advanced business analytics.

As the EV charging market is expanding, our client aimed to create a unified ecosystem where stations, users, and investors can interact barrier-free and transparently. They asked Devox Software to build a robust, scalable, growth-first platform that could handle complex IoT communications, financial operations, and real-time data visualization.

Over the course of two years, a dedicated team worked on the project. The team included 1 solution architect, 2 back-end developers, 1 IoT developer, 1 UI designer, and 1 web designer. The project was also guided by a senior project manager.

Since the development began before the popularity of EVs, the team encountered several general difficulties, which they successfully transformed into challenges and ultimately overcame. Those included the following:

• Custom IoT Protocol: At that time, there were no ready-made libraries available, so our team had to simulate the backend communication protocol from scratch to amalgamate hardware and software.
• Real-Time Updates: One of the requirements was to match the accurate, real-time data updates with the user map and account.
• Multi-Platform Notifications: We needed to build a notification system for both mobile and web apps.
• Secure Wallet Management: The app required a secure and compliant wallet top-up and balance management system for the user’s convenience.

Back-End: .NET, NodeJS, REST API

Mobile Apps: Native iOS & Android

Database: PostgreSQL

Real-Time Communication: SignalR

During the first stage of product development, we’ve created an MVP with the following major features and advancements:

• A web app and mobile apps for iOS and Android. This way, the business accounts leveraged extended feature sets, including statistics and reporting in bulk.
• A custom communication protocol for charging stations, built from scratch without pre-existing libraries.
• A user cabinet with a digital wallet, real-time map updates via SignalR, notifications, and reports.
• A payment management system enabling wallet top-ups.
• Dashboards with comprehensive reporting and analytics.

As a result, over the years, the platform has been improved with new features, tuned performance, and support for new EV charging station models.

The client and customers were satisfied with the results, fostering and scaling the platform across many countries:

• A successful MVP launch has allowed the client to enter the EV charging market quickly.
• The margin and 30% more investment capital in 2 years have enabled stable platform growth, expanding services to 10+ countries across Europe.
• Compliance and audit were successfully carried out with zero findings, ensuring regulatory readiness and operational excellence.
• Our solution has enabled the customer to establish a strong market presence in the growing EV sector, as evidenced by their expansion to 10+ countries and 40% increase in profitability within 2 years through integrated technology and business operations.
