The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve. To understand the discharge characteristic curve of a battery, we first need to understand the voltage of the battery in principle.
These curves drawn with the battery cell parameters such as time, capacity, SOC, voltage, etc. involved in charge and discharge as coordinates are called charge and discharge curves. Here are some common charge and discharge curves. Time-current/voltage curve ● Constant current
The lithium battery discharge curve is a curve in which the capacity of a lithium battery changes with the change of the discharge current at different discharge rates. Specifically, its discharge curve shows a gradually declining characteristic when a lithium battery is operated at a lower discharge rate (such as C/2, C/3, C/5, C/10, etc.).
The simplest cycle life curve is with the number of cycles as the x-axis and the discharge capacity or capacity retention rate as the y-axis, as shown in the figure below. As the cycle progresses, the battery capacity continues to decay, and the charge and discharge system has a significant impact on the battery capacity decay.
The state of charge at which a battery starts its discharge cycle significantly impacts the voltage curve. Batteries with higher SoCs generally begin at higher voltages, which can translate to better performance in the initial phases of discharge. Monitoring SoC is vital for applications requiring precise power management.
Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
