🎯 Battery capacity sorting PART Ⅱ
There are various methods for battery capacity sorting, including charge/discharge cycling, open circuit voltage measurement, and impedance measurement. These methods involve subjecting batteries to controlled discharge and charge cycles, or measuring their electrical characteristics, in order to determine their capacity.
📌 Charge/discharge cycling involves repeatedly charging and discharging batteries to determine their capacity. Batteries are first charged to their full capacity and then discharged to a set voltage or current level. The discharge capacity is then measured, and the battery is charged again. This process is repeated until the battery’s capacity stabilizes, allowing for an accurate capacity rating to be determined.
📌 Open circuit voltage measurement involves measuring the voltage of a battery when it is not connected to a load. This voltage is related to the state of charge of the battery and can be used to estimate the battery’s capacity.
📌 Impedance measurement involves measuring the resistance of a battery to an alternating current (AC) signal. This resistance is related to the battery’s internal resistance, which in turn is related to its capacity.
Overall, battery capacity sorting is an important technique for ensuring consistent battery performance and improving battery life in various applications.
