This cell must be stored in a cool, dry environment to prevent degradation. Prolonged exposure to temperatures exceeding 55°C or below -40°C during operation must be avoided to maintain performance and safety.
- Temperature Limits: Operate the cell only within the discharge temperature range of -40°C to 55°C and charge temperature range of -10°C to 45°C.
- Storage Conditions: Store the cell in a cool, dry environment away from direct sunlight and moisture.
- Mechanical Integrity: Do not disassemble, deform, short-circuit, or incinerate the cell to prevent thermal runaway or leakage.
- Electrical Protection: Use a battery management system with cell balancing and overcurrent protection in any battery pack assembly.
- Charging Protocol: Charge at 0.2C when the cell temperature is between -10°C and 0°C, and up to 2C between 0°C and 45°C.
Follow these steps to safely handle and deploy the cell for use in battery packs. Proper temperature management and protection circuitry are critical for safe operation.
Required Equipment: Charger with cut-off voltage of 3.65V ± 0.05V, Battery management system (BMS) with cell balancing and overcurrent protection
- Inspect Packaging
Inspect the packaging for damage upon receipt and handle with care. - Store Properly
Store the cell in a cool, dry environment with temperature between -40°C and 55°C. - Verify Temperature
Verify that the cell temperature is within the safe charging range of -10°C to 45°C before connecting a charger. - Connect BMS
Connect the cell to a battery management system with balancing and overcurrent protection before assembly. - Set Charge Current
Adjust the charge current to 0.2C if the cell temperature is between -10°C and 0°C, or to 2C if above 0°C. - Avoid Hazards
Avoid disassembling, deforming, short-circuiting, or incinerating the cell at any time.
How does the maximum continuous charge current vary with temperature for the ATOMFAIR 3.2V 20Ah wide-temperature cell?
The maximum continuous charge current is temperature-dependent. At 0°C to 45°C, the cell supports 2C charging, but at low temperatures from -10°C to 0°C, it is limited to 0.2C to ensure safe and stable charging as specified in the technical datasheet.
What protection circuitry is required when integrating this prismatic cell into a battery pack?
The cell requires a protection circuit that prevents overcharging beyond the charge cut-off voltage of 3.65V ± 0.05V and provides cell balancing. The manufacturer explicitly states that appropriate cell balancing and protection circuitry must be utilized in battery pack assembly, and the internal resistance of ≤3.5 mΩ should be considered for current sensing.
What are the recommended storage conditions for the ATOMFAIR 3.2V 20Ah prismatic cell to maintain cycle life?
Store cells in a cool, dry environment, and avoid prolonged exposure to temperatures above 55°C or below -40°C during operation. Although storage conditions are not explicitly separated from operational limits, the supplied information indicates that the cell is designed for reliable discharge from -40°C to 55°C, so storage within that temperature range in a low-humidity environment is recommended to preserve its 3,000-cycle life.
The ATOMFAIR 3.2V 20Ah prismatic LFP cell delivers 2C continuous discharge down to -40°C and 0.2C charging at -10°C, with a 3000-cycle lifespan, making it suitable for electric motorcycles, AGVs, and humanoid robots operating in extreme climates.
Positive
- Wide-temperature discharge down to -40°C: The cell supports 2C continuous discharge from -40°C to 55°C, enabling reliable power delivery in extreme cold without preheating, critical for outdoor AGV and electric motorcycle applications.
- Long cycle life with LFP chemistry: Lithium iron phosphate chemistry provides up to 3,000 cycles, reducing replacement frequency in high-utilization scenarios such as portable energy storage and lead-acid replacement systems.
Trade-offs
- Low-temperature charging rate limitation: Charging below 0°C is restricted to 0.2C (4 A), which extends recharge time significantly in sub-zero environments and may require thermal management for rapid turnaround.
- Storage and handling sensitivity: Prolonged exposure to temperatures above 55°C or below -40°C during operation degrades performance; cells require cool, dry storage and protection circuitry to prevent damage from short-circuit or over-discharge.
