9.3. How to Calculate the Operation Time
●5120Wh * DOD * η / (load W) = operation time (unit: hour/time)
If I want to know how many times 96W Macbook Pro could be recharged.
5120Wh * 90% * 90% / 96W = 43 times
●What is the depth of discharge (DoD)?
To extend the battery-life, the power station set the 90% DOD, which means that
only 90% of the battery capacity can be discharged. 10% of the energy is reserved
to avoid damage to the battery due to over-discharge.
η indicates local inverter eciency. DOD=90%, η =90%.
