Performance Characteristics
The following graphs illustrate the performance of the LFP5.42KWH51.2V-P20R1QT50 battery under various conditions:
Different Rate Discharge Curve @ 25°C
This graph displays battery voltage over discharge time for different discharge rates (0.1C, 0.2C, 0.5C, 1C, 1.5C) at a constant temperature of 25°C. It shows how voltage drops more significantly with higher discharge rates.
Different Temperature Discharge Curve @ 0.5C
This graph illustrates battery voltage versus nominal capacity for a 0.5C discharge rate across various ambient temperatures, ranging from 0°C to 50°C. It highlights the impact of temperature on discharge performance, with lower temperatures generally resulting in lower voltage and capacity.
State of Charge Curve @ 0.5C 25°C
This graph shows the relationship between battery voltage, State of Charge (SOC) percentage, and charging time during a 0.5C charge at 25°C. It helps visualize the charging process and voltage changes as the battery reaches full charge.
Charging Characteristics @ 0.5C 25°C
This graph depicts the battery voltage and charge current (as a percentage of nominal current) during a 0.5C charge at 25°C. It illustrates how the charge current and voltage behave throughout the charging cycle.
Different DOD Discharge Cycle Life Curve @ 0.5C 25°C
This graph presents the expected cycle life of the battery at a 0.5C discharge rate and 25°C for different Depth of Discharge (DOD) levels: 30%, 50%, 80%, and 100%. It demonstrates that higher DOD levels lead to fewer overall cycles.
Different Temperature Self Discharge Curve
This graph shows the remaining capacity (%) of the battery over storage time (in months) at different temperatures: -25°C, 10°C, 30°C, 40°C, and 50°C. It indicates that higher storage temperatures accelerate the self-discharge rate.
