Learn MoreEnergy throughput is the total amount of energy a battery can be expected to store and deliver over its lifetime. This term would be especially useful written into the warranties of all battery products. Let''s say the example 10kWh battery bank mentioned above has a warranty on its throughput instead of its cycle life.
Learn MoreThe state of charge (SoC) is essentially the opposite of depth of discharge. SoC is the percentage of battery capacity still stored and available in the battery. To continue our earlier example, an 8 kWh battery with a Depth of Discharge of 75% has a state of charge of 25%, or 2 kWh remaining. Similarly, you could call the little battery charge ...

Learn MoreWhat does SoC, SoH and DoD mean? SoC stands for State of Charge, which is a measure of how much energy is remaining in a battery as a percentage of its fully charged capacity. So, if a battery has a 50% SoC, it means that it has used up 50% of its total energy capacity. SoH stands for State of Health, which is a measure of the overall health ...
Learn MoreDepth of Discharge (DOD) refers to how much energy is cycled into and out of the battery on a given cycle. It''s expressed as a percentage of the total capacity of the battery. For those new the industry, DOD sounds like it may be a difficult topic to understand, but it''s actually simple. For instance, a battery that has been drained 30% has a ...
Learn MoreTo calculate DOD, you need to divide the capacity discharged from a fully charged battery by the battery''s nominal capacity and express the result as a percentage. For example, if you have a lithium battery with 100 Ah of usable capacity and you use 40 Ah then you would say that the battery has a depth of discharge of 40 / 100 = 40%.
