Discharge characteristics (25°C)
A graph showing voltage versus discharge time at various current rates (0.1C, 0.2C, 0.3C, 0.5C, 1C). The voltage drops gradually over time, with higher current rates causing a faster and more significant voltage drop.
Different DOD Discharge cycle life Curve 0.2C 25°C
A graph illustrating cycle life at 0.2C discharge rate at 25°C for different Depth of Discharge (DOD) levels (30%, 50%, 80%, 100%). The graph shows that as the DOD increases, the cycle life decreases. For 80% DOD, the cycle life exceeds 2000 cycles.
Different Temperature Discharge Curve (0.5C)
A graph displaying voltage versus capacity percentage at 0.5C discharge rate across different temperatures (-10°C, 0°C, 10°C, 20°C, 30°C, 40°C, 50°C). The curves indicate that performance is generally better at higher temperatures, with voltage remaining higher for a given capacity.
State of Charge Curve (0.5C, 25°C)
A graph showing voltage and state of charge percentage versus charging time in minutes at 0.5C rate and 25°C. The voltage increases steadily during charging, and the state of charge reaches 100% at approximately 120 minutes.
