Performance Characteristics

The following section details the performance characteristics of the LFP5.12KWH51.2V-P20R3 battery through graphical representations.

Different Rate Discharge Curve @ 25°C

This graph illustrates discharge voltage curves at 25°C for various discharge rates (0.1C, 0.2C, 0.5C, 1C, 1.5C). It shows that higher discharge rates result in lower voltage levels and shorter discharge times, indicating reduced efficiency at higher loads.

Different Temperature Discharge Curve @ 0.5C

This chart displays discharge voltage curves at a 0.5C rate across different temperatures (0°C, 10°C, 20°C, 30°C, 40°C, 50°C). It indicates that lower temperatures lead to reduced discharge voltage and capacity, highlighting the impact of ambient temperature on performance.

State of Charge Curve @ 0.5C 25°C

This graph plots voltage and State of Charge (SOC) against charging time at 0.5C and 25°C. It shows the voltage rising and stabilizing as the battery charges, with SOC increasing approximately linearly with time during the charging process.

Charging Characteristics @ 0.5C 25°C

This chart shows voltage and charging current as a percentage of nominal capacity during charging at 0.5C and 25°C. It demonstrates the typical charging profile, including constant current and constant voltage phases, to reach full charge efficiently.

Different DOD Discharge Cycle Life Curve @ 0.5C 25°C

This graph illustrates the cycle life of the battery at 25°C and 0.5C discharge rate for different Depth of Discharge (DOD) levels (30%, 50%, 80%, 100%). It shows that higher DOD levels result in fewer total cycles before the battery's capacity degrades significantly.

Different Temperature Self Discharge Curve

This graph displays the remaining capacity over storage time (in months) at different temperatures (10°C, 25°C, 30°C, 40°C, 50°C). It indicates that self-discharge rates increase with higher storage temperatures, meaning the battery loses charge faster when stored in warmer conditions.
