What does depth of discharge (DOD) mean?
Depth of Discharge (DOD): Balancing Energy Usage and Battery Life DOD indicates the percentage of battery capacity used before recharging. For example, a 100Ah battery discharged by 80Ah has a DOD of 80%. While a higher DOD allows more energy utilization, excessive discharge shortens battery life.
Does a higher depth of discharge make a battery better?
The better performance of a battery is not necessarily connected to a higher depth of discharge. For most batteries, it is advised to avoid high depth of discharge. When we say a battery has a higher DoD, it means we can use more energy before recharging it.
How to calculate battery depth of discharge?
It is super simple to calculate the battery depth of discharge. The steps you should follow while calculating DoD are as follows. Step 1: Determine the battery's initial capacity. This is usually presented in watt-hours (Wh) or amp-hours (Ah).
How do you calculate depth of discharge?
Depth of discharge = (used energy/initial capacity) x 100 Suppose a battery has a total capacity of 200Ah and 100Ah of energy has already been used out of the total. In that case, the depth of discharge will be 50% ( (100Ah/200Ah)x100). As mentioned earlier, DoD is a variable value that can differ for each discharge cycle.
Why does a battery need a deep discharge?
But that’s exactly where a battery’s efficiency comes in with an often-overlooked hidden force: Depth of Discharge (DoD). It’s a delicate balance that could make or break your device’s reliability where too deep discharges shorten your battery’s lifespan or too shallow discharge rate leaves the energy on the table.
What is the difference between depth of discharge and state of charge?
The depth of discharge shows how empty the glass is or how much water is taken out of the glass. On the other hand, the state of charge shows how full the glass is or the current level of water available inside the glass. If you want to understand the energy status of the battery, both DoD and SoC are equally important to consider.
