Energy Storage System
State of Health & Best Practices
Project Overview
Energy storage system (ESS) degradation poses a significant challenge to widespread advanced technology vehicle adoption due to costly replacements and impacts to reliability and service planning.
This project seeks to establish best practices for measuring ESS state of health. Additionally, by analyzing real-world data and identifying key factors affecting ESS health, we will also develop proven best practices to extend ESS lifespan, reduce operational costs, and improve fleet reliability through predictive maintenance and operations schedules.
Why it Matters
Energy Storage Systems are the most expensive component of an advanced technology vehicle.
Extending their life means fewer replacements and lower costs.
Unplanned downtime disrupts transit services.
Smarter ESS management keeps buses on the road.
Charging, operations, and climate all impact ESS health.
Operators need data-driven strategies to optimize performance.
