EV Charging Management Platform
UX/UI Design for EroEV

EroEV is a CleanTech SaaS platform built to manage and grow EV charging networks. The platform brings together four groups that need to work in sync: charging providers who own and operate the infrastructure, station administrators who configure and monitor it, and EV drivers who need to locate a charger, plug in, and pay without friction.

The technical backbone is OCPP 1.6, the industry-standard protocol for communication between EV chargers and the management software running them. Through this, EroEV gives drivers real-time session monitoring, remote charging control, and Razorpay-powered digital wallet payments. On the other side, administrators and providers get complete visibility over their stations, connectors, sessions, and revenue through a centralised web platform.

When EroEV came to us in 2024, they had the infrastructure vision and the hardware. What they needed was the software: a full-stack platform designed and developed from scratch, built for a market where EV adoption was accelerating faster than the tools to support it.

EroEV is a scalable EV Charging Management Platform that connects drivers, charging providers, and administrators through a unified ecosystem.

The solution includes a React Native mobile app for locating and booking chargers, monitoring charging sessions, and making seamless payments, along with dedicated web dashboards for providers and administrators to manage stations, users, transactions, and network operations. Built on OCPP 1.6 with a real-time WebSocket backend, the platform ensures reliable communication and seamless charging experiences across the network.

• Locate available chargers within a 5 km radius, select a connector, set a charging goal by kWh or target spend amount, initiate the session remotely, track live progress, and complete payment through a Razorpay digital wallet automatically on session close.
• Charging providers register their business and station locations, then configure and manage OCPP 1.6-compatible chargers under their accounts through a dedicated web dashboard.
• Platform administrators provision chargers, monitor all providers and stations, manage users and transactions, and track revenue and operational performance across the entire network.
• Websocket infrastructure that handles multiple simultaneous charging sessions, live meter values, and real-time command processing without connection drops or session failures.

Building a platform that connects physical charging hardware to software users through a real-time communication protocol is not a straightforward design problem. These were the challenges that shaped every decision:

Scaling OCPP 1.6 When Every Second Counts:

• OCPP 1.6 websocket connections between the platform and chargers need to stay live through the entire charging session. Every few seconds, the charger sends live meter values back to the platform. When a session hits its target, the platform sends a stop command. If the connection drops at any point, the session breaks and the driver is left mid-charge. Scaling this to handle dozens of concurrent sessions required backend database optimisation and server scaling before the UX could work as designed.

Three Distinct User Types, One Unified Platform:

• A charging provider logging in wants to see their stations, sessions, and revenue. An administrator needs visibility across every provider and every transaction on the network. An EV driver on their phone wants the nearest available charger and a way to start charging in under a minute. Designing for all three without any one interface bleeding into another required strict role-based architecture from the start.

Making Goal-Based Charging Feel Obvious, Not Complicated:

• Setting a charging target by kWh or by spend amount is a feature most EV apps do not offer. For drivers used to plugging in and unplugging manually, this is a new mental model. The UX had to introduce and explain this option at the right moment in the flow without adding steps, without requiring a tutorial, and without creating doubt about whether the session would actually stop at the right point.

Designing for a Market Still Finding Its Shape:

• India’s EV charging infrastructure in 2024 was early. Standards were being adopted. User habits around public charging were forming in real time. The platform had to be designed for how things work today while being built in a way that can absorb new charger types, new payment methods, and new providers without needing a fundamental rebuild every 18 months.
