This document outlines the environmental and safety constraints for the ATOMFAIR 3.2V 280Ah prismatic cell. Adherence to these constraints is critical for safe operation and maximizing cycle life.

  • Storage Environment: Store cells in a cool, dry environment to prevent capacity degradation and ensure long-term stability.
  • Operating Temperature Range: Maintain the cell's operating temperature between -50°C and 60°C during discharge and between -30°C and 55°C during charging.
  • Cycle Life Constraints: Cycle life is temperature-dependent, with ≥6000 cycles at 25°C and ≥1000 cycles at -10°C under specified charge/discharge conditions.
  • Safety Constraints: Do not disassemble, deform, short-circuit, or incinerate the cell to prevent thermal runaway or explosion.
  • Charging Current Constraints: Standard charge current must be limited to 0.15C when the cell temperature is between -20°C and 0°C and 0.5C when between 0°C and 55°C.

This procedure describes the safe handling, storage, and charging steps for the ATOMFAIR wide-temperature prismatic cell. Following these steps ensures operational safety and maximizes battery performance and longevity.

Required Equipment: Cell balancing and protection circuitry

  1. Store the cell
    Store the cell in a cool, dry environment to prevent capacity degradation.
  2. Verify temperature
    Verify the cell's temperature is within the charging range of -30°C to 55°C before initiating a charge cycle.
  3. Connect balancing circuitry
    Connect the cell to a cell balancing and protection circuitry before assembling into a battery pack.
  4. Charge at standard rate
    Charge the cell at 0.5C standard charge current when the cell temperature is between 0°C and 55°C, or at 0.15C between -20°C and 0°C.
  5. Discharge at standard rate
    Discharge the cell at 0.5C standard discharge current when the temperature is between -40°C and 60°C.
  6. Prevent short-circuit
    Prevent short-circuiting the cell by ensuring proper insulation and handling.

What is the maximum continuous discharge current at -50°C compared to warmer temperatures?

At -50°C to -40°C, the standard discharge current is 56.0 A (0.2C), while at -40°C to 60°C it increases to 140.0 A (0.5C). The maximum continuous discharge of 1.5C (420.0 A) is only available at -40°C to 55°C with SOC > 50%, as specified in the technical data.

What BMS or protection circuitry is required for integrating this 280 Ah prismatic cell into a battery pack?

The cell requires appropriate cell balancing and protection circuitry to prevent overcharge, over-discharge, and short circuits. The charge cut-off voltage is 3.65 V and discharge cut-off is 2.0 V, and the internal resistance is ≤0.3 mΩ, so the BMS must monitor voltage and temperature to ensure operation within the specified charging temperature range of -30°C to 55°C and discharging range of -50°C to 60°C.

What are the recommended storage conditions for the ATOMFAIR 3.2V 280Ah wide-temperature cell to preserve cycle life?

Store cells in a cool, dry environment, avoiding prolonged exposure to temperatures above 60°C or below -50°C during operation. The packaging includes individual protective insulation for square prismatic formats, and the manufacturer advises against disassembly, deformation, short-circuiting, or incineration to ensure safe handling and long-term reliability.

The ATOMFAIR 3.2V 280Ah prismatic cell delivers validated discharge down to -50°C and charging down to -30°C, with 1.5C continuous and 2.5C pulse discharge capability, making it suitable for extreme-environment energy storage and high-power applications.

Positive

  • Ultra-wide temperature operation: Reliable discharge from -50°C to 60°C and stable charging from -30°C to 55°C, enabling uninterrupted performance in extreme climatic conditions.
  • High rate capability: Supports 1.5C continuous discharge and 2.5C pulse discharge for 30 seconds, delivering instant high-power output when needed.

Trade-offs

  • Reduced charge current at low temperature: Standard charge current is limited to 0.15C (42.0A) between -20°C and 0°C, requiring longer charging times under cold conditions.
  • Requires external protection circuitry: Proper cell balancing and protection circuitry must be used in battery pack assembly to ensure safe operation and prevent damage from overcharge, overdischarge, or short circuits.
