Our Fundamental Question

How long will a train battery really last – and how can we predict it before it fails?

In this challenge, we invite makers, engineers, and algorithm enthusiasts to develop a remaining useful life (RUL) prediction for railway battery systems. The goal is to assess battery health and forecast failures using real operational data.

The Challenge

You will design a solution that:

  • Measures charge/discharge voltage and current

  • Determines the state of health of battery packs

  • Predicts the remaining lifetime based on real degradation behavior

The focus is on enabling better maintenance decisions and avoiding unexpected battery failures.

What Makes This Interesting

  • Data-driven problem with clear real-world relevance

  • Combines hardware measurement, modeling, and algorithms

  • High impact: better reliability, lower costs, fewer failures

Technical Focus Areas

  • Acquisition of voltage and current during charge/discharge cycles

  • Battery state estimation based on real measurements

  • Development of a lifetime prediction algorithm using failure data

  • Cost-efficient, mobile hardware solution

  • Data transmission to a backend or server system

Who Should Join?

  • Makers interested in energy systems and batteries

  • Data scientists and algorithm developers

  • Embedded and IoT engineers

  • Teams passionate about predictive maintenance and sustainability

If you enjoy working with real data and building systems that predict the future instead of reacting to failures, this challenge is for you.

Join us and help shape the next generation of intelligent battery systems!
