Nickel-based batteries, like nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries, are also more resilient to deep discharges and can handle DoDs of around 80% without severe consequences. Part 6. How to calculate the DoD of battery？ Calculating the depth of discharge (DoD) of a battery is straightforward.
A battery’s depth of discharge indicates the percentage of the battery that has been discharged relative to the overall capacity of the battery. For example, if you have a 100 amp-hour battery and use only 20 amp-hours you have discharged your battery by 20%, which means your depth of discharge is 20%, and your state of charge is 80%.
For almost all known rechargeable battery technologies, such as lead-acid batteries of all kinds like AGM, there is a correlation between the depth of discharge and the cycle life of the battery. [ 10 ]
1. Lithium-ion (Li-ion) battery depth of discharge For lithium-ion (Li-ion) batteries, it is generally recommended to avoid deep discharges below 20% to prolong their lifespan. This means you shouldn’t drain them more than 80% before recharging.
Yes, it is dangerous to attempt to charge a deeply discharged Lithium battery. Most Lithium charger ICs measure each cell's voltage when charging begins and if the voltage is below a minimum of 2.5V to 3.0V it attempts a charge at a very low current . If the voltage does not rise then the charger IC stops charging and alerts an alarm.
No, it is not OK to have a Li-Ion deeply discharged at all. Here is why: When discharged below its safe low voltage (exact number different between manufacturers) some of the copper in the anode copper current collector (a part of the battery) can dissolve into the electrolyte.
Lithium Battery Depth of Discharge, State of Charge & Capacity
Depth of discharge (DoD) is an important parameter appearing in the context of rechargeable battery operation. Two non-identical definitions can be found in commercial and scientific sources. The depth of discharge is defined as: 1. the maximum fraction of a battery''s capacity (given in Ah) which is removed from the charged battery on a regular basis. "Charged" does not necessarily refer to fully or 100 % charged, but r…
