6 FAQs about [Battery discharge current change]

What affects the change of battery discharge voltage?

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.

How does current affect battery discharge time?

The current flowing out of the battery during the discharging process determines how quickly the battery will be depleted. A higher current means a faster discharge time, while a lower current means a slower discharge time.

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 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.

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:

How does discharge rate affect battery performance?

The capacity decreases from 1.41 Ah to 1.22 Ah when the discharge rate increases from 100 mA to 500 mA. The critical influence of factors like age, temperature, and discharge rate on battery performance underscores the need to analyze current drain to validate actual battery run time.
