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.
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.).
A typical discharge curve consists of three sections. The first section represents the exponential voltage drop when the battery is charged. The width of the drop depends on the battery type. The second section represents the charge that can be extracted from the battery until the voltage drops below the battery nominal voltage.
The discharge cut-off voltage of the battery: the discharge time set by the electrode material and the limit of the electrode reaction itself is generally 3.0V or 2.75V. d.
At the same time, the end voltage change of the battery is collected to detect the discharge characteristics of the battery. Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop.
The slope of the lithium battery charging curve reflects the fast charging speed. , the greater the slope, the faster the charging speed. At the same time, the platform area of the lithium battery charging curve indicates that the battery is fully charged, and the voltage tends to be stable at this time.
Discharge Characteristics of Lithium-Ion Batteries
1. Understanding the Discharge Curve. The discharge curve of a lithium-ion battery is a critical tool for visualizing its performance over time. It can be divided into three distinct regions: Initial Phase. In this phase, the voltage remains relatively stable, presenting a flat plateau as the battery discharges. This indicates a consistent energy output, essential for …
