4 FAQs about Flow battery discharge depth
How deep should a 12V battery be discharged?
The recommended depth of discharge for a 12V battery depends on the battery chemistry and the manufacturer’s instructions. As a general rule of thumb, lead-acid batteries typically have a DoD of around 50%, while lithium-ion and LiFePO4 batteries can have a depth of discharge ranging from 70%-90%. What Does 80% DoD Mean?
How deep should a rechargeable battery be discharged?
Different types of batteries have different recommended depths of discharge. Recommended DoD varies based on numerous factors, but battery chemistry is the most essential. Lead acid batteries — the oldest form of rechargeable battery technology — typically have a recommended DoD of around 50%.
What does depth of discharge mean on a battery?
Depth of discharge (DoD) measures how much of a battery’s total electricity storage capacity has been consumed. Depending on battery chemistry, DoD can vary widely — from 50% (lead acid) to 80% (Li-ion/LiFePO4). DoD significantly impacts how much electricity you can use without permanently damaging a battery.
Can a flow battery be discharged without damaging the cell structure?
In flow batteries, high depth of discharge is possible which means most of its nominal capacity can be discharged without imposing any permanent damage to the cell structure 22. In addition, they can store electroactive materials required for battery operation in a tank outside the battery structure.
