Performance Characteristics
The following graphs illustrate the battery's performance under various conditions:
Different Rate Discharge Curve @ 25°C
This graph displays the battery voltage over discharge time for different discharge rates (0.1C, 0.2C, 0.5C, 1C, 1.5C) at a constant temperature of 25°C. It shows that higher discharge rates lead to a faster decrease in voltage.
Different Temperature Discharge Curve @ 0.5C
This graph illustrates the battery voltage relative to the nominal capacity percentage for various ambient temperatures (-10°C, 0°C, 10°C, 20°C, 30°C, 40°C, 50°C) when discharging at a 0.5C rate. It highlights the impact of temperature on discharge performance, with lower temperatures generally resulting in lower voltages at the same capacity.
State of Charge Curve @ 0.5C 25°C
This graph plots the battery voltage and State of Charge (SOC) percentage against charging time for a 0.5C charging rate at 25°C. It provides insight into the battery's charging profile and how its SOC changes over time.
Charging Characteristics @ 0.5C 25°C
This graph shows the battery voltage and charging current percentage in relation to the charge current percentage, under a 0.5C charging rate at 25°C. It details the charging current behavior during the charging process.
Different DOD Discharge Cycle Life Curve @ 0.5C 25°C
This graph presents the remaining capacity percentage versus the number of cycles for different Depth of Discharge (DOD) levels (30%, 50%, 80%, 100%) at 0.5C discharge rate and 25°C. It serves as an indicator of the battery's expected lifespan under varying usage depths.
Different Temperature Self Discharge Curve
This graph illustrates the remaining capacity percentage over storage time (in months) at different storage temperatures (-10°C, 10°C, 25°C, 40°C, 50°C). It demonstrates how ambient temperature affects the rate at which the battery loses charge when not in use.
