How the work runs

The pressure that made this worth automating, the steps the system runs, and what came out the other side.

Pressure & Trigger Points

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.
