6 FAQs about [Battery constant current discharge diagram]

What is a constant current discharge of a lithium ion battery?

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.

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.

How does a battery discharge?

The nature of the load (constant current, constant power, or variable load) affects how the battery discharges. Constant power loads, for example, will lead to a different voltage drop pattern compared to constant current loads. 8. Internal Impedance:

What is the formula for constant current discharge?

At constant current discharge, W = I * U (t) dt = It * u (u is the average discharge voltage, t is the discharge time) a. Theoretical energy The discharge process of the battery is in an equilibrium state, and the discharge voltage maintains the value of electromotive force (E), and the utilization rate of the active substance is 100%.

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.
