What is Depth of Discharge (DOD) in Lithium battery
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). 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. Nowadays, phones have settings for the battery where the maximum capacity of charge and depth of discharge of the lithium battery can be set in the phone settings.
In the same way, the Depth of Discharge becomes essential as the battery becomes older, and if we reduce the DOD of the battery as per the use, then the life of the battery can be further enhanced. So, all kinds of lithium batteries come with a life cycle based on the depth of discharge. The higher the depth of discharge, the lower the cycle one will get.
