State of Health Diagnostics

Operational Protocol

Sensor data collected during charge and discharge cycles feed into algorithmic models that track internal resistance and voltage capacity loss. Algorithms compare current performance curves against baseline data established during initial manufacturing. This process separates temporary capacity loss from permanent chemical aging.

Thermal stress or prolonged high current discharge accelerates the decay identified by these systematic observations.

Economic Consequence

Residual value assessment relies on accurate cycle life projections to define trade prices for secondary market applications. Procurement departments utilize these readings to determine if a storage unit maintains the performance threshold required for stationary grid support. Replacement schedules shift based on the specific degradation rate observed in the field rather than calendar aging estimates.

Evaluation Limit

Measurements apply only to the specific environmental conditions active during the assessment period. Results gathered under laboratory temperature control shift when the hardware encounters extreme ambient cold or heat. Reliable estimations require consistent data input across multiple full cycles to filter out variance in ambient temperature or operational noise.

Low voltage operation during the final stages of discharge renders these diagnostic results unreliable for verifying long term stability.
