Performance Characteristics
The following section details the performance characteristics of the battery through various graphical representations:
Different Rate Discharge Curve @ 25°C
This graph illustrates the battery's voltage response over discharge time at 25°C for different discharge rates (0.1C, 0.2C, 0.5C, 1C, 1.5C). Higher discharge rates lead to a more pronounced voltage drop.
Different Temperature Discharge Curve @ 0.5C
This chart shows the battery's voltage versus nominal capacity at a 0.5C discharge rate across a range of temperatures (0°C to 50°C). Performance is generally better at higher temperatures, with lower temperatures causing a more significant voltage decrease.
State of Charge Curve @ 0.5C 25°C
This graph plots battery voltage and State of Charge (SOC) against charging time at 25°C for different charge rates (0.05C, 0.25C, 0.5C), demonstrating the charging progression.
Charging Characteristics @ 0.5C 25°C
This visualization displays the charging voltage and current profile during a 0.5C charge at 25°C, showing how voltage and current interact during the charging process.
Different DOD Discharge Cycle Life Curve @ 0.5C 25°C
This graph projects the battery's cycle life (remaining capacity vs. number of cycles) at 25°C and 0.5C discharge rate for varying depths of discharge (30%, 50%, 80%, 100%). Deeper discharges reduce the total number of cycles achievable.
Different Temperature Self Discharge Curve
This chart illustrates the battery's self-discharge rate over storage time (months) at different temperatures (10°C, 25°C, 30°C, 40°C, 50°C). Lower storage temperatures result in slower capacity loss.
