Free QuoteDepth of Discharge affects how often a battery can be cycled and how much usable energy it can provide. AGM Batteries can typically handle a DoD of around 50% to 70%
Free QuoteIn many types of batteries, the full energy stored in the battery cannot be withdrawn (in other words, the battery cannot be fully discharged) without causing serious, and often irreparable damage to the battery. The Depth of Discharge (DOD) of a battery determines the fraction of power that can be withdrawn from the battery.
When the discharge voltage falls below the cut-off voltage specified by the manufacturer (usually 2.5V or 2.8V), the battery is considered over-discharged. Frequent over-discharge accelerates battery aging, shortens battery life, and can cause the battery to generate excess gas and heat internally, leading to swelling or leakage.
The investigations show, that it is most advisable to discharge whole battery systems by energy recuperation into grid with electronic adjustable loads, because of efficiency and safety reasons. Overdischarging is not problematic if crucial battery parameters are observed.
However, frequent deep discharges will lead to a gradual decrease in the capacity of the lithium battery. The active substances in the battery will be irreversibly lost during deep discharge, resulting in lower battery capacity and shorter cycle life. Want to extend the battery life of your cell phone?
The Depth of Discharge (DOD) of a battery determines the fraction of power that can be withdrawn from the battery. For example, if the DOD of a battery is given by the manufacturer as 25%, then only 25% of the battery capacity can be used by the load.
In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A.
