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.
What does the slope of a lithium battery discharge curve mean?
The slope of the lithium battery discharge curve can reflect the discharge performance of the battery. A flatter lithium battery discharge curve usually indicates that the lithium battery has better discharge stability and can provide stable energy output.
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
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 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.
What are the underlying mechanisms of charge–discharge behaviour of batteries?
Understanding the underlying mechanisms of the charge–discharge behaviour of batteries, especially Li-ion and Na-ion intercalation ones, is obligatory to develop and design energy storage devices. The behaviour of the voltage–capacity/time (V – C / T) diagram is one of the most critical issues which should be understood.
