What happens during the discharge process of a battery?

Discharge Process: During the discharge process, the battery’s chemical reactions undergo a reversal. Lithium ions migrate from the negative electrode to the positive electrode, while electrons travel from the negative electrode to the positive electrode.

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 determines a battery discharge rate?

The discharge rate is determined by the vehicle’s acceleration and power requirements, along with the battery’s design. The charging and discharging processes are the vital components of power batteries in electric vehicles. They enable the storage and conversion of electrical energy, offering a sustainable power solution for the EV revolution.

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 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 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.
