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.
The change of the battery discharge voltage is related to the discharge system, that is, the change of the discharge curve is also affected by the discharge system, including: discharge current, discharge temperature, discharge termination voltage; intermittent or continuous discharge.
The initial discharge voltage and voltage platform of the battery will decrease as the discharge rate increases. The discharge capacity at 0.8C, 1C, and 1.5C has a similar change curve with the number of cycles.
When the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. 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.
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.
During the second stage of battery discharge, the discharge curve changes to stable, and the battery enters the platform region. At this time, the electrochemical reaction state inside the battery is mild.
What Is Deep Discharge and How Does It Affect Batteries?
Depth of Discharge (DoD) measures the energy a battery has used. For example, if you have a fully charged battery rated at 100 Ah and used 40 Ah, your DoD is 40%. The state of Charge (SoC) indicates how much energy remains available in the battery at any given time. Using the previous example, if you have used 40 Ah from your fully charged 100 …

Does a Battery Lose Voltage As It Discharges? (Why Does)
Does the Voltage of a Battery Decrease Over Time . As batteries age, their voltage decreases. The rate at which this happens depends on the type of battery, but all batteries will eventually reach a point where they can no longer power a device. This can be a problem for devices that require a specific voltage to function properly, such as laptops and smartphones.

Definition of DoD and its relation to cycle count: Depth of discharge (DoD) refers to the percentage of the battery''s capacity used during a discharge cycle. A higher DoD means the battery is discharged more deeply. The DoD has a direct relationship with the cycle count, as deeper discharges typically contribute to a shorter overall cycle count.
