6 FAQs about [Discharge curve of battery pack]

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 is a lithium battery discharge curve?

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.).

What is a red curve in a battery pack charging process?

The red curves are all the cell voltages of the battery pack charging process, which contains four constant-current processes with different rates. The charging current is shown as the green curve. The extraction of characteristic VCSs is mainly carried out in the first stage of constant-current process.

How do charging voltage curves affect battery capacity?

Firstly, the similarity of the charging voltage curves of the single cells within the battery pack is discussed with the help of the battery equivalent model and the aging test data.

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 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
