6 FAQs about [Formula for selecting batteries for constant power discharge]
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 a battery discharge curve?
To implement the method and approach of [ 8, 9 ], battery discharge curves are required at constant power, where the battery voltage and current vary. This is atypical from the usual method of battery performance characterization, where the current is fixed and power and voltage are variable.
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 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.
What is a standard battery characterization procedure?
Standard battery testing procedure consists of discharging the battery at constant current. However, for battery powered aircraft application, consideration of the cruise portion of the flight envelope suggests that power should be kept constant, implying that battery characterization should occur over a constant power discharge.
