Performance Characteristics
The following graphs illustrate the performance characteristics of the LFP5.12KWH25.6V-P65L2GF40 battery:
Different Rate Discharge Curve @ 25°C
This graph displays the battery's voltage response over discharge time at a constant temperature of 25°C for various discharge rates (0.1C, 0.2C, 0.5C, 1C, 1.5C). It shows how higher discharge rates lead to a faster voltage drop.
Different Temperature Discharge Curve @ 0.5C
This graph illustrates the discharge performance at a 0.5C rate across a range of temperatures (-10°C to 50°C). It plots voltage against nominal capacity percentage, demonstrating the impact of temperature on discharge capability.
State of Charge Curve @ 0.5C 25°C
This chart shows the battery's charging process at 0.5C and 25°C. It plots both voltage and State of Charge (SOC) percentage against charging time, illustrating the charging profile.
Charging Characteristics @ 0.5C 25°C
This graph presents the charging voltage and charge current percentages over time at 25°C for 0.5C and 0.25C charge rates, detailing the charging efficiency and voltage regulation.
Different DOD Discharge Cycle Life Curve @ 0.5C 25°C
This graph depicts the cycle life of the battery at 25°C and 0.5C discharge rate under different Depth of Discharge (DOD) conditions (30%, 50%, 80%, 100%). It shows the remaining capacity percentage versus the number of cycles, highlighting the battery's longevity.
Different Temperature Self Discharge Curve
This graph illustrates the self-discharge rate of the battery at various temperatures (-10°C to 50°C) over storage time (in months). It plots the remaining capacity percentage against storage time, indicating how temperature affects the rate at which the battery loses charge when not in use.
