This lithium-ion cell requires operation within a charge temperature range of 10°C to 45°C and a discharge range of -20°C to 45°C. The cell voltage must be maintained between 3.0V and 4.3V, and continuous discharge current should not exceed 30A (2C) to prevent thermal runaway.
- Charge Temperature Range: Charge the cell only within 10°C to 45°C to avoid degradation.
- Discharge Temperature Range: Discharge the cell only within -20°C to 45°C to maintain performance.
- Voltage Limits: Maintain cell voltage between 3.0V and 4.3V during operation to prevent over-discharge or overcharge.
- Continuous Discharge Current Limit: Limit continuous discharge current to 30A (2C) to avoid excessive heating.
- Charger Requirement: Use a dedicated lithium-ion charger with CC/CV mode for safe charging.
What is the maximum continuous and pulse discharge current rating for the 8540140-15 cell at different states of charge?
The cell supports a maximum continuous discharge of 2C (30A) over the full operating temperature range (-20 to 45°C) and a pulse discharge of 5C (75A) for 10 seconds at 50% SOC. At lower SOC, pulse capability may be reduced; the specification explicitly states the pulse condition at 50% SOC.
What charger specifications are required for safe charging of the 8540140-15 cell?
The cell requires a dedicated lithium-ion charger with CC/CV (constant current/constant voltage) mode. The charge voltage range is 3.0V to 4.3V (work voltage range), and the recommended charge temperature is 10°C to 45°C. Using an improper charger may lead to safety risks.
What safety tests has the 8540140-15 cell passed to ensure reliability in research applications?
The cell has passed rigorous safety tests including over-discharge, external short circuit, low pressure, and fall tests with no fire or explosion risks. These tests confirm its suitability for high-energy-density power system R&D and other demanding applications.
The 8540140-15 is a 15Ah lithium-ion power cell with a slim 8.5mm profile, delivering up to 30A continuous and 75A pulse discharge, but requires careful thermal management for charging below 10°C and external BMS integration for safe operation.
Positive
- High Capacity Density in Slim Profile: The cell delivers 15Ah nominal capacity in an 8.5mm thickness, enabling high-energy-density pack designs with minimal spatial footprint.
- High Continuous and Pulse Discharge: Supports 2C (30A) continuous discharge and 5C (75A) pulse for 10 seconds, suitable for high-power applications like UAVs and electric vehicles.
Trade-offs
- Restricted Charging Temperature Range: Charging is limited to 10°C to 45°C; operation below 10°C requires thermal management to avoid damage or reduced performance.
- Requires External BMS and Dedicated Charger: The cell is a bare lithium-ion cell requiring an external BMS for safety and a CC/CV charger, adding integration complexity and cost.
