DoD
DoD in the SpeicherCampus context: depth of discharge and the usable share of the battery. Technically, the term is usually described as Depth of Discharge.
What does DoD mean?
Depth of Discharge states how much of the nominal capacity is actually withdrawn. 90 % DoD on 200 kWh means: 180 kWh are used, 20 kWh remain in the cell as a reserve.
Modern LFP systems permit high depths of discharge (sometimes 100 % per datasheet), but DoD remains a design lever: cycling shallower slows ageing — exhausting the warranted capacity is paid for in lifetime.
What matters in practice
- usable capacity = nominal capacity × DoD — calculate with nothing else
- datasheet DoD and warranty DoD can differ
- a backup reserve reduces the everyday usable depth of discharge
- respect BMS limits: deep discharge is a damage event
Practical example
A system “with 215 kWh” runs 90 % DoD in daily operation and holds a 30 % backup reserve. Effectively it shifts about 130 kWh per day — that number, not the 215, belongs in the economic analysis.
The SpeicherCampus perspective
SpeicherCampus always converts offers to usable capacity at real DoD — the honest comparison figure behind the catalogue number.
