Depth of Discharge (DoD) refers to the percentage of a battery’s total capacity that has been used during a discharge cycle.
Expanded Explanation
DoD indicates how deeply a battery is discharged before being recharged. For example, a battery discharged to 30% remaining capacity has experienced a 70% DoD. Higher DoD levels generally place more stress on battery cells and can accelerate aging, while shallower discharges typically extend battery lifespan. Many battery systems are designed to operate within defined DoD limits to balance usable runtime and long-term durability.
Why it matters
Managing DoD helps optimize battery longevity and predictable performance.
iTECH Context
iTECH considers DoD limits when designing battery systems to meet runtime and lifespan targets.
