What is the discharge characteristic curve of a battery?
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.
How to determine battery discharge capacity?
The charging conditions of the battery: charging rate, temperature, cut-off voltage affect the capacity of the battery, thus determining the discharge capacity. Method of determination of battery capacity: Different industries have different test standards according to the working conditions.
What is the discharge cut-off voltage of a battery?
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.
What is the relationship between depth of discharge and battery life?
DOD (Depth of Discharge) is the discharge depth, a measure of the discharge degree, which is the percentage of the discharge capacity to the total discharge capacity. The depth of discharge has a great relationship with the life of the battery: the deeper the discharge depth, the shorter the life. The relationship is calculated for SOC = 100% -DOD
How does discharge voltage affect battery capacity?
Evidently, increasing discharge current causes a decrease in the apparent Ah capacity. The final discharge voltage also varies depending on the discharge current. The discharge capacity is affected by the battery temperature during discharge. Generally, the capacity decreases when the battery temperature decreases during discharge.
What is a constant current discharge in a battery?
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.
