Performance Characteristics
Different Rate Discharge Curve@25°C
This graph plots Voltage (V) against Discharge Time (h) at a constant temperature of 25°C for various discharge rates (0.1C, 0.2C, 0.5C, 1C, 1.5C). It shows how the voltage drops over time for each rate, with higher rates causing a steeper voltage decline.
Different Temperature Discharge Curve@0.5C
This graph plots Voltage (V) against Nominal Capacity (%) at a discharge rate of 0.5C for different temperatures (-10°C, 0°C, 10°C, 20°C, 30°C, 40°C, 50°C). It illustrates how temperature affects the battery's voltage output as capacity is depleted.
State of Charge Curve@0.5C 25°C
This graph plots Voltage (V) and Charge Current (A) against Charging Time (min) at a 0.5C charge rate and 25°C. It shows the voltage rising and the charge current decreasing as the battery reaches full charge.
Charging Characteristics @0.5C 25°C
This graph plots Voltage (V) and Charge Current (%) against Charge Current (%) at 0.5C charge rate and 25°C. It shows the voltage profile and the charge current profile during charging.
Different DOD Discharge Cycle Life Curve@0.5C 25°C
This graph plots Remaining Capacity (%) against Number of Cycles for different Depth of Discharge (DOD) percentages (30%, 50%, 80%, 100%) at a 0.5C rate and 25°C. It demonstrates the expected cycle life of the battery at various discharge depths.
Different Temperature Self Discharge Curve
This graph plots Remaining Capacity (%) against Storage Time (Months) at different storage temperatures (-10°C, 25°C, 30°C, 40°C, 50°C). It shows how quickly the battery loses charge over time when stored at various temperatures.
