Exceeding the 1.0C maximum continuous charge or discharge rate may cause thermal runaway. The specified cycle life requires operation at 25°C with 0.5C/0.5C rates at 100% DOD.
- Physical Specification: The cell weighs ≤4.30 kg and measures 53.8 × 174.2 × 207.1 mm with terminal.
Inspect the cell for physical damage and verify its voltage before integration. Operate within the specified charge and discharge rates to maintain safety and cycle life.
Required Equipment:
- Inspect Cell
Inspect the cell for visible cracks, dents, or electrolyte leakage before handling. - Measure Voltage
Measure the open-circuit voltage using a multimeter to confirm it is near the nominal 3.22 V. - Set Charging Current
Set the charging current to no more than 228 A (1.0C) to comply with the maximum continuous charge rate. - Control Temperature
Use a temperature-controlled environment at 25°C during cycling to achieve the specified cycle life of ≥4000 cycles. - Discharge Safely
Discharge the cell at a rate not exceeding 228 A (1.0C) to prevent overheating.
How does the 175Wh/kg energy density of this 228Ah LFP cell translate to real-world EV range trade-offs compared to NMC chemistries at similar capacity?
The 3.22V 228Ah LFP prismatic cell delivers 175Wh/kg, which is lower than typical NMC cells (200-260Wh/kg), requiring a heavier or larger pack for the same range. However, its ≥4000 cycle life at 0.5C/0.5C, 100% DOD with 80% retention provides a significant total energy throughput advantage over NMC, which typically degrades to 80% capacity after 1000-2000 cycles, making the LFP cell more cost-effective over the full vehicle lifetime for fleet and bus applications.
Can this 53.8×174.2×207.1mm prismatic LFP cell be directly integrated into existing EV pack designs optimized for pouch or cylindrical cells?
Integration with pouch or cylindrical cell pack designs is not direct due to the prismatic form factor's distinct mechanical and thermal management requirements. The square aluminum case with terminal (53.8×174.2×207.1mm including terminal) necessitates a specific compression fixture and cooling plate interface, unlike pouch cells requiring rigid end plates or cylindrical cells needing cooling channels. Its 1.0C continuous charge/discharge rate demands a custom BMS with high-current handling capacity.
What are the specific storage and handling requirements for this ≤4.30kg LFP cell to prevent premature degradation or safety incidents before pack assembly?
The cell requires humidity-controlled vacuum sealed packaging and anti-static foam lined cartons for isolation, as specified. Storage must avoid mechanical abuse, over-discharge, and short circuits, with conditioning under standard ambient conditions before first use. The LFP chemistry's thermal stability reduces runaway risk, but a dedicated BMS with voltage and temperature protection is mandatory, and disposal must follow local regulations due to residual energy.
The ATOMFAIR 3.22V 228Ah LFP prismatic cell provides high energy density (175 Wh/kg) and exceptional cycle life (≥4000 cycles at 100% DOD) for EV traction packs, while requiring mandatory BMS protection and being limited to 1.0C continuous rates.
Positive
- High Gravimetric Energy Density (175 Wh/kg): The cell achieves 175 Wh/kg, enabling extended driving range for EVs while reducing overall pack weight, as specified in the technical data.
- Exceptional Cycle Life (≥4000 cycles at 100% DOD): With ≥4000 cycles at 0.5C/0.5C and 80% capacity retention, this cell is built for long-life fleet and commercial EV applications, minimizing replacement frequency.
Trade-offs
- Mandatory BMS and Voltage/Temperature Control: The cell must always be used with a dedicated BMS and within specified voltage and temperature ranges to prevent over-discharge, short circuits, and thermal runaway, as per manufacturer's notice.
- Limited Continuous C-Rate to 1.0C: The maximum continuous charge and discharge rate is 1.0C, which may restrict applications requiring higher power delivery or faster charging beyond this rating.
