Performance Curves
Discharge Characteristics (25°C)
Describes voltage drop over time for various discharge rates (1C, 0.5C, 0.3C, 0.2C). Voltage remains relatively stable during discharge, dropping more significantly at higher discharge rates and towards the end of discharge.
Different Temperature Discharge Curve (0.5C)
Illustrates voltage versus capacity at different temperatures (-10°C to 50°C). Performance is slightly better at higher temperatures, showing less voltage drop for a given capacity.
Different DOD Discharge Cycle Life Curve (0.2C, 25°C)
Details cycle life versus the number of cycles for different Depth of Discharge (DOD) levels (100%, 80%, 50%, 30%) at a 0.2C rate and 25°C. Higher DOD results in fewer cycles.
State of Charge Curve (0.5C, 25°C)
Shows the relationship between voltage and charging time (minutes) for State of Charge (SoC) and voltage during charging and discharging at 0.5C and 25°C. Features steep voltage changes during charging/discharging and a flatter middle section.
