Performance Characteristics
Different Rate Discharge Curve @ 25°C: This graph illustrates the voltage behavior of the battery during discharge at 25°C under various discharge rates (0.1C, 0.2C, 0.5C, 1C, 1.5C). It shows that higher discharge rates result in a more pronounced voltage drop.
Different Temperature Discharge Curve @ 0.5C: This chart displays the battery's voltage performance at a 0.5C discharge rate across different temperatures (-10°C, 0°C, 20°C, 30°C, 40°C, 50°C). It indicates that lower temperatures lead to reduced voltage and capacity retention.
State of Charge Curve @ 0.5C 25°C: This graph presents the relationship between battery voltage and State of Charge (SOC) during both charging and discharging at 0.5C and 25°C. The voltage remains relatively stable during the primary discharge phase.
Charging Characteristics @ 0.5C 25°C: This chart shows the voltage and current profiles during charging at 0.5C and 25°C. The charging current is maintained at a constant level until the battery approaches full charge, after which it tapers off.
Different DOD Discharge Cycle Life Curve @ 0.5C 25°C: This graph illustrates the expected cycle life of the battery at 25°C and 0.5C discharge for different Depth of Discharge (DOD) levels (30%, 50%, 80%, 100%). It demonstrates that a lower DOD results in a significantly longer cycle life.
Different Temperature Self Discharge Curve: This chart shows the rate at which the battery loses charge when stored at different temperatures (10°C, 25°C, 30°C, 40°C, 50°C) over time (in months). The self-discharge rate increases with higher storage temperatures.
