4 · Cons: Must disconnect all loads and chargers and let battery rest. Battery voltage changes depending on charge and discharge rates. Plus, LiFePO4 batteries have a relatively flat discharge curve from around 99% to 20% capacity. Because of these factors, it can be hard to estimate their state of charge from voltage alone.
The discharge curve basically reflects the state of the electrode, which is the superposition of the state changes of the positive and negative electrodes. The voltage curve of lithium-ion batteries throughout the discharge process can be divided into three stages. 1) In the initial stage of the battery, the voltage drops rapidly, and the ...
Losses at fast discharges reduce the discharge time and these losses also affect charge times. A C-rate of 1C is also known as a one-hour discharge; 0.5C or C/2 is a two-hour discharge and 0.2C or C/5 is a 5-hour discharge. Some high-performance batteries can be charged and discharged above 1C with moderate stress.
[8][9][10][11][12] Self-discharge is one of the most important indicators for quality assurance of lithium-ion cells, and it refers to the spontaneous capacity loss under open circuit conditions.
