The internal resistance of the battery increases with the increase of the discharge current of the battery, which is mainly because the large discharge current increases the polarization trend of the battery, and the larger the discharge current, the more obvious the polarization trend, as shown in Figure 2.
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.
The discharge rate, expressed in C-rates, is a crucial factor affecting battery performance. Higher discharge rates lead to increased internal resistance, resulting in more significant voltage drops. For instance, discharging at a rate of 2C can considerably reduce the battery’s capacity compared to lower rates.
It’s important to understand why your battery might not be fully charged when needed, its reliability, and the overall battery life. Self-Discharge is Inevitable in All Batteries: Self-discharge is a natural phenomenon where batteries lose their charge over time even when not in use.
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.
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.
