Discharge Profile
Definition
Time-varying pattern of current or power draw from a battery during operation. Can be constant, pulsed, or variable depending on application.
Why It Matters
- Determines battery sizing and thermal management requirements
- Complex profiles require detailed analysis vs. simple constant power
- Affects capacity utilization and voltage behavior
- Used for battery simulation and validation testing
Common Pitfalls
- Not capturing worst-case peaks in profile specification
- Assuming average power determines battery size (peaks matter)
- Not accounting for temperature effects on profile capability
- Not testing with representative discharge profile
