Different Rate Discharge Curve @ 25°C

This graph illustrates voltage discharge curves at various discharge rates (0.1C, 0.2C, 0.5C, 1C, 1.5C) at a constant temperature of 25°C. It shows how voltage drops over discharge time for each rate, with higher rates leading to faster voltage decline and lower end-of-discharge voltage.

Different Temperature Discharge Curve @ 0.5C

This graph displays voltage discharge curves at a 0.5C rate across different temperatures (-10°C, 0°C, 10°C, 20°C, 30°C, 40°C, 50°C). It demonstrates the impact of temperature on battery performance, showing that lower temperatures result in a steeper voltage drop and reduced capacity.

State of Charge Curve @ 0.5C 25°C

This graph plots voltage and State of Charge (SOC) percentage against charging time at a 0.5C rate and 25°C. It shows a relatively flat voltage curve during the main charging phase, with SOC increasing linearly with time, and a distinct voltage rise towards the end of charge.

Charging Characteristics @ 0.5C 25°C

This graph illustrates voltage and charge current profiles during charging at different rates (0.05C, 0.25C, 0.5C) at 25°C. It shows how the charge current is regulated and how the voltage rises to the charge cut-off point as the battery approaches full charge.

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

This graph presents 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 indicates that higher DOD levels result in fewer charge/discharge cycles before significant capacity degradation.

Different Temperature Self Discharge Curve

This graph shows the remaining capacity percentage over storage time (in months) at various temperatures (-10°C, 0°C, 10°C, 25°C, 40°C, 50°C). It illustrates the self-discharge rate of the battery, which increases with temperature.
