The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery’s lifespan.
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.
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.
The depth of discharge refers to the percentage of a battery’s total capacity utilized during a discharging cycle. While lithium-ion batteries can handle shallow discharges without much impact on their longevity, deep discharges, especially below 20% DoD, can cause strain on the battery and reduce its lifespan.
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 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.
