6 Frequently Asked Questions about “Lithium battery constant current discharge”
What is a constant current discharge of a lithium ion 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. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
Does discharge rate affect lithium-ion battery cell characteristics?
An experimental analysis to study lithium-ion battery cell characteristics at different discharge rates is presented. Based on constant current discharge experiments and hybrid pulse power characteristics experiments, discharge rate effects on cell thermal characteristic, capacity characteristic and electrical characteristic are analyzed.
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 happens when a lithium ion battery discharges?
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.
How does discharge current affect battery capacity?
An increase in the discharge current of the battery may decrease the effective capacity due to a decline of the reactivity of the battery's active materials. Mathematically, this is expressed as: where P is the Peukert constant, i is current and K is a constant.
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.
