Meaning
Continuous streams of digital sensor data recorded during vehicle operation track battery temperature, voltage, and current to provide a verifiable history of cell usage. Analyzing telematics logs allows fleet operators and cell buyers to monitor the health of high-voltage systems in real time. This recorded dataset is the primary evidence used to settle warranty disputes between vehicle makers and cell suppliers.
It proves whether the battery was operated within its approved temperature and charge limits.
Data Collection
The onboard telematics unit transmits battery metrics such as state of charge, cell voltages, and charging rates to a secure database. These records are stored continuously throughout the life of the vehicle. If a pack fails, engineers download these logs to trace the events leading up to the failure.
This helps pinpoint the source of the breakdown.
Commercial Sourcing
Sourcing contracts require that telematics logs remain accessible to both parties to ensure transparency during claims. The buyer must prove that the vehicle did not exceed limits before the supplier pays for replacements. This makes data access a priority point in contracts.
Warranty Verification
These databases help resolve arguments over battery degradation. This data shows whether the cells were abused.
