Engineering calculator
Battery energy & runtime
Usable energy and runtime of a battery system at a constant load.
Inputs
Results
- Nominal energy
- 22kWh
- Usable energy
- 15.84kWh
- Runtime
- 10.56h
Runtime = Ah × V × DoD × η / Pload
Assumptions
- Constant power load
- Rated temperature
Limitations
- Ignores Peukert effect, ageing and temperature derating — substation DC systems should be sized to IEEE 485 / AS 4086
