RV Battery Systems

Short Overview

SuperVolt, a Germany-based company specializing in advanced energy solutions for motorhomes and RV systems, is expanding its product line with a connected solution that gives users real-time insight and remote control over battery performance. The new system allows RV owners to track key parameters, manage their energy setup remotely, and ensure safe, efficient operation — all through intuitive web and mobile applications.

Project Background

SuperVolt's existing mobile app connected to the battery's BMS over BLE but ran on a legacy, tightly coupled codebase, and the UI no longer matched real RV usage. As the product line evolved and new hardware interfaces were planned, these limitations became evident. Therefore, SuperVolt turned to Indeema to improve and modernize the mobile app, laying a stronger foundation for what comes next.

What was the customer's request?

SuperVolt asked Indeema to modernize its mobile bms app — the companion app that connects to the battery's BMS and shows key status (state of charge, voltage, temperature). The brief was to refresh the UI and add new features to enhance the ownership experience and provide added value to SuperVolt's LiFePO4 batteries sold in Germany.

What did the client already have?

SuperVolt came with an existing mobile app that connected to the battery's BMS (via Bluetooth) and displayed core status such as state of charge, voltage, and temperature. The app's UI and user flows needed refinement to make the experience more user-friendly and consistent with real RV use.

UX/UI Design

The client provided an initial design, which we refined to make the app more user-friendly. We identified the primary user groups and considered their behavior and usage context — where and how they use the app — and reflected these insights in the updated UI.

Mobile Development

Following a focused code review of the existing app, we concluded that extending the legacy architecture would be impractical and more expensive than rebuilding. We therefore proceeded with a clean implementation from scratch to provide a stable, scalable base for upcoming features.

Maintenance

We continue iterating on the app with focused feature updates and UX refinements. As the third-party BMS firmware evolves, we add support for new battery capabilities and ensure the app remains stable, scalable, and aligned with the latest device functionality.
