- Inspect cell condition
Inspect the cell for physical damage, swelling, or leakage before any handling. - Connect to BMS
Connect the cell to a BMS configured for low-charge and high-discharge protocols. - Set voltage window
Set the voltage window to 3.0V–4.3V on the management system. - Initiate charging
Initiate charging at a constant current rate of 0.5C maximum within the set voltage range. - Monitor discharge
Monitor continuous discharge rate to remain at or below 3C during operation.
How does the energy density of the EC02 series solid-state cells affect cycle life under high-altitude long-endurance mission profiles?
The EC02 series cells, available in 420Wh/kg and 490Wh/kg variants, are both rated for a cycle life of ≥50 cycles at room temperature under 0.2C charge and 3C continuous discharge conditions. The product specification does not indicate a cycle life penalty for the higher energy density variant; both share identical cycle life ratings. For HALE missions, the larger capacity of the 490Wh/kg cell (15Ah vs 3Ah) may reduce the number of cycles required per mission, but the baseline cycle life remains unchanged.
What are the voltage and temperature constraints for integrating EC02 series cells into a HALE UAV power system?
The EC02 series cells have a nominal voltage of 3.83V and an operating voltage range of 3.0V to 4.3V. They are rated for operation from -20°C to 60°C, with stable 3C continuous discharge performance. Integration requires a BMS with specialized protocols for low-charge/high-discharge cycles typical of high-altitude operations, as noted in the customization section. Custom form factors are also available for aerodynamic integration.
What specialized handling or infrastructure is required for storing and integrating EC02 series solid-state cells?
The product description does not specify unique storage conditions beyond standard aerospace-grade handling, but it emphasizes that comprehensive thermal data and discharge curve profiles are available for aerospace simulation upon request, indicating thermal management is critical. Additionally, specialized BMS engineering is offered for low-charge/high-discharge cycles, meaning standard BMS may not be sufficient for HALE operations. For bulk or institutional inquiries, direct contact with Atomfair is required.
The EC02 series solid-state cells offer industry-leading energy density up to 490Wh/kg for extreme UAV applications, but with a cycle life of only 50 cycles and a 0.5C max charge rate, they are optimized for short-duration high-performance missions rather than long-term cycling.
Positive
- Ultra-high energy density up to 490Wh/kg: Industry-shattering energy density of up to 490Wh/kg provides the highest energy-to-weight ratio for extreme flight requirements, enabling increased payload or extended airtime on weight-constrained HALE platforms.
- Optimized for HALE missions with stable 3C discharge: Specifically designed for High-Altitude Long-Endurance (HALE) missions, maintaining stable 3C continuous discharge under operational loads, ensuring reliable power delivery during extended high-altitude operations.
Trade-offs
- Limited cycle life: ≥50 cycles at RT: Cycle life at room temperature is specified as only ≥50 cycles under 0.2C charge/3C discharge conditions, making these cells unsuitable for applications requiring frequent recharging over long operational lifetimes.
- Slow max charge rate of 0.5C: Maximum charge rate is limited to 0.5C, which may require extended charging periods between missions and constrains rapid turnaround scenarios in time-sensitive operations.
