Planning retirements from telematics data
Most fleet vehicles already report charge history, depth of discharge and temperature exposure. Those signals are a strong early indicator of how packs will grade. Vehicles that fast-charged heavily in hot conditions tend to retire with lower and more uneven module health than vehicles charged slowly overnight, even at the same mileage.
We use that data to forecast the grade mix of each retirement batch, reserve collection capacity and give finance teams a realistic residual-value range well before vehicles leave service. Bench testing still sets the final price, but the forecast removes most of the surprise.
- Cumulative energy throughput per pack
- Share of DC fast charging
- Time spent at high state of charge
- Temperature exposure and any thermal warnings
Running depot decommissioning safely
Removing packs at the depot keeps vehicles out of transit and shortens the time packs spend in storage. It also concentrates risk in one place, so the site plan matters. Crews need a segregated isolation area, rated lifting equipment, clear access for collection vehicles and a defined response for any pack that shows damage or heat.
Once removed, packs are discharged below 30% state of charge where practical, labelled and staged for same-week collection. Any pack with swelling, coolant leaks or a thermal history is separated and collected under the damaged-and-defective protocol.
| Requirement | Why it matters |
|---|---|
| Segregated isolation bay | Keeps high-voltage work away from live operations |
| Rated battery table or forklift | Safe removal of heavy packs |
| Access for collection vehicles | Avoids double handling and dwell time |
| Quarantine area | Separates damaged packs immediately |
