Battery Warranty Evaluation for OAD Profile
Working Condition Simulation and Analytical Model
Insert logo here
| Model Basis | Description |
|---|---|
| Data basis and driving habits | Probability distribution model of charging, driving, and parking frequency. |
| Working condition MAP | SOC interval, charge/discharge ratio, running state, charging mode, and charging throughput. |
| Temperature correction and matrix | Regional ambient temperature profile from weather inputs. System temperature correction from ambient temperature and thermal rise assumptions. Cycle/calendar weighted factor matrix generated from operating and temperature distributions. |
| Life and iteration model | Semi-empirical Arrhenius-style cell life model calibrated by cycle and calendar life data. Periodic iteration model eliminates nonlinear attenuation effects across the simulated lifetime. |
| Evaluation outputs and deviation | Capacity retention curves, SOH trajectories, degradation splits, and detail tables. No deviation from the software input profile has been recorded. |
