BatteryGuard AI is a predictive tool that uses AI to monitor the health and safety of second-life lithium-ion batteries. It helps users—especially in community energy projects—predict battery failures, estimate remaining life, and prevent safety risks. The system provides clear, explainable outputs so non-experts can understand and trust the insights.
Inspiration
This project was inspired by the growing use of second-life batteries in off-grid and low-resource areas. While these reused batteries are sustainable and affordable, they can fail without proper monitoring. BatteryGuard AI empowers users with a safe, smart, and responsible way to manage energy storage using AI.
What it does
BatteryGuard AI predicts the health and remaining life of second-life lithium-ion batteries using historical data (voltage, temperature, current). It detects early warning signs of failure, flags risks, and explains its decisions—making battery safety understandable for non-experts.
How we built it
We trained an Neural Network model using publicly available datasets (e.g., NASA, CALCE) to forecast battery degradation and detect anomalies. A Streamlit-based dashboard visualizes predictions, health scores, and interpretable alerts powered by SHAP. AWS SageMaker was used for model deployment.
Challenges we ran into
Finding high-quality open data for second-life batteries Balancing model accuracy with explainability Designing a simple interface for users without technical backgrounds
Accomplishments that we're proud of
Building a working prototype with real-time predictions Integrating explainable AI for battery health decisions Aligning our solution with responsible AI principles
What we learned
How to apply time-series AI to real-world battery problems The importance of interpretability in safety-critical systems How cross-disciplinary collaboration strengthens social impact solutions
What's next for BatteryGuard AI
Expand training on real second-life battery data Collaborate with NGOs and clean energy startups for pilot testing Package the tool as an open-source solution or low-cost SaaS for the energy access market
