6 FAQs about [Battery instantaneous discharge speed]

How does discharge rate affect battery characteristics?

As a key factor, discharge rate has a great influence on battery characteristics. Therefore, it is particularly important to study the characteristics of LIB at different discharge rates. Battery discharge is the process of converting chemical energy into electrical energy and releasing the energy to the load.

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 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 is the discharge capacity of a battery?

Under the condition of discharge rate of 0.5C, 0.8C, 1C, 2C, 3C and 4C, the discharge capacity of the cell is 3312mAh, 3274mAh, 3233mAh, 2983mAh, 2194mAh and 976mAh, which is 3.58%, 4.69%, 5.88%, 13.16%, 36.13% and 71.59% lower than the standard capacity 3435mAh provided by the battery manufacturer.

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 happens if a battery is discharged constant power?

Keep the discharge power unchanged, because the voltage of the battery continues to drop during the discharge process, so the current in the constant power discharge continues to rise. Due to the constant power discharge, the time coordinate axis is easily converted into the energy (the product of power and time) coordinate axis.
