Performance Characteristics
Different Rate Discharge Curve @ 25°C
This graph illustrates the voltage behavior of the battery under different discharge rates (0.1C, 0.2C, 0.5C, 1C, 1.5C) at 25°C. It shows that higher discharge rates lead to a more pronounced voltage drop and a shorter discharge duration.
Different Temperature Discharge Curve @ 0.5C
This graph displays the battery's voltage performance across various temperatures (-10°C, 0°C, 10°C, 20°C, 30°C, 40°C, 50°C) when discharged at a 0.5C rate. It indicates that lower temperatures reduce the available capacity and impact voltage stability.
State of Charge Curve @ 0.5C 25°C
This chart shows the relationship between battery voltage, charging current, and State of Charge (SOC) during a 0.5C charge at 25°C. The voltage gradually increases as the battery charges towards 100% SOC.
Charging Characteristics @ 0.5C 25°C
This graph presents the voltage and charge current profiles during a 0.5C charge at 25°C. Initially, the charge current is constant, but it tapers off as the battery approaches full charge, accompanied by a rise in voltage.
Different DOD Discharge Cycle Life Curve @ 0.5C 25°C
This graph illustrates the battery's cycle life at 25°C and 0.5C discharge rate for different Depth of Discharge (DOD) levels (30%, 50%, 80%, 100%). It demonstrates that higher DOD levels result in a shorter overall cycle life before significant capacity degradation.
Different Temperature Self Discharge Curve
This chart shows how the remaining capacity of the battery changes over storage time (in months) at different temperatures (10°C, 25°C, 30°C, 40°C, 50°C). The data indicates that self-discharge rates increase with higher storage temperatures.
