Performance Curves
Discharge characteristics (25°C): This graph illustrates the voltage drop over time for different continuous discharge currents (0.1C, 0.2C, 0.3C, 0.5C) at 25°C, with a cut-off voltage of 10.8V. The voltage remains relatively stable for longer durations at lower discharge rates.
State of Charge Curve (0.5C, 25°C): This graph shows the relationship between battery voltage and state of charge (in percentage) during a 0.5C discharge at 25°C. The voltage decreases gradually as the battery discharges.
Discharge characteristics (25°C) - Capacity vs. Cycle: This graph displays the battery's capacity retention over a number of cycles for different depths of discharge (30% DOD, 50% DOD, 80% DOD, 100% DOD) at 25°C. It shows that higher DOD leads to faster capacity degradation.
Different Temperature Discharge Curve (0.5C): This graph illustrates how battery voltage and state of charge change during a 0.5C discharge at various temperatures (-10°C, 0°C, 10°C, 20°C, 30°C, 40°C, 50°C). Lower temperatures generally result in lower voltage and potentially reduced performance.
