How does the DoD measure battery discharge percentage?
The DOD measures the battery discharge percentage. Lithium batteries of all kinds of chemistry come with a Battery Management system, which can monitor and control the depth of discharge for the lithium-ion battery. The Depth of Discharge control is significant for the battery life.
How does the DoD determine a battery's state of charge?
DoD determines how much energy a battery has already discharged or used. It measures how empty the battery is after use. In contrast, the state of charge is the current energy level available in the battery. It shows how empty or full a battery is at a given moment. Let's understand the concept with a real-life example. Think of a glass of water.
What is the difference between DOD and battery capacity?
DoD is a variable value that determines what percentage of capacity has been used. On the other hand, capacity is a fixed value that represents the total energy a battery can have. Let's understand this concept with an example. Suppose the total capacity of a battery is 100 units, and 50 units are already consumed.
How does DoD affect battery life?
DoD has a great impact on the battery's life. A higher value of the depth of discharge means a large percentage of electricity is used before recharging. Generally, this practice leads to a shorter lifespan of a battery. The batteries that are frequently discharged deeply degrade faster than usual. Plus, they lose their capacity with time.
What is depth of discharge (DOD) for a lithium battery?
Explained and Analyzed Depth of Discharge (DoD) for a lithium battery refers to how much of its total capacity has been used before recharging. It is expressed as a percentage of the battery’s total energy capacity. For example, if a 100 Ah lithium battery is discharged to 20 Ah, its DoD is 80% (80 Ah used, 20 Ah remaining).
How do you calculate the DoD of a battery?
To calculate the DoD, divide the discharged energy by the initial capacity and multiply by 100 to get the percentage. For example, if a battery with a capacity of 100 Ah has been discharged by 50 Ah, the DoD would be (50 Ah / 100 Ah) x 100% = 50%.
