Technical Specifications

Performance Characteristics

The following performance characteristics illustrate the battery's behavior under various conditions:

Different Rate Discharge Curve @25°C

This graph plots Voltage (V) against Discharge Time (minutes) at 25°C for different discharge rates (0.1C, 0.2C, 0.5C, 1C, 1.5C). It shows that higher discharge rates lead to a steeper voltage drop and shorter discharge duration.

Different Temperature Discharge Curve @0.5C

This graph plots Voltage (V) against Nominal Capacity (%) at a 0.5C discharge rate for various temperatures (-10°C, 0°C, 10°C, 20°C, 30°C, 40°C, 50°C). It indicates that performance, particularly voltage stability, is affected by temperature, with lower temperatures resulting in lower voltage output.

State of Charge Curve @0.5C 25°C

This graph shows Voltage (V) and State of Charge (SOC %) against Charging Time (minutes) during a 0.5C charge at 25°C. It illustrates the charging profile, showing how voltage and SOC increase over time.

Charging Characteristics @0.5C 25°C

This graph plots Voltage (V) and Charge Current (%) against Charge Current (A) during a 0.5C charge at 25°C. It displays the charging voltage and current profile as the battery charges.

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

This graph plots Remaining Capacity (%) against Number of Cycles for different Depth of Discharge (DOD) levels (30%, 50%, 80%, 100%) at a 0.5C discharge rate and 25°C. It demonstrates that lower DOD levels significantly extend the battery's cycle life.

Different Temperature Self Discharge Curve

This graph plots Remaining Capacity (%) against Storage Time (Months) for different storage temperatures (10°C, 25°C, 30°C, 40°C, 50°C). It shows that higher storage temperatures lead to a faster self-discharge rate.
