EV Battery Degradation & Thermal Runaway Monitoring for Transit Fleets
A metropolitan transit authority operating 600 electric buses under demanding urban stop-and-go driving conditions and extreme summer temperatures.
Run on Vahana · Asset Reliability & Fleet
The challenge
High-voltage battery pack degradation was uneven across the fleet, reducing vehicle operating range unpredictably.
Thermal stress spikes during fast-charging cycles threatened cell degradation and catastrophic thermal runaway risks.
Transit managers lacked real-time visibility into State of Health (SoH) and remaining range across individual battery packs.
How Vahana solves it
High-Voltage Telemetry Ingestion
Vahana streams cell-level temperature, voltage differentials, current draw, and State of Charge (SoC) metrics in real time.
Thermal Anomaly & Runaway Prevention
Flags anomalous cell temperature rises during fast-charging, automatically throttling charge rates to protect battery health.
Battery State of Health (SoH) Profiling
Computes dynamic SoH degradation curves for every battery pack based on historical thermal cycles and depth of discharge.
Smart Route & Depot Dispatching
Assigns buses to routes dynamically matching vehicle battery health to route terrain severity.
Warranty Claim Data Package Generation
Generates verifiable telemetry packages to claim OEM battery warranty replacements for prematurely degraded cells.
The outcome
- OEM battery replacement warranties backed by indisputable cell
- $0MOEM battery replacement warranties backed by indisputable cell
Extended fleet battery pack lifespan by an estimated 2.5 years through thermal risk throttling.
Eliminated unexpected EV bus route stalls by matching battery SoH to route severity.
Recovered $1.4M in OEM battery replacement warranties backed by indisputable cell telemetry logs.
