- Specialized Stratospheric Aircraft
- Ultra-Lightweight Research Prototyping
- Deep-Endurance Reconnaissance Platforms
Accessories & Customization
BMS Engineering: Specialized management protocols for low-charge/high-discharge cycles typical of high-altitude operations.
Custom Form Factors: Bespoke dimensions available for aerodynamic integration in specialized specialized airframes.
Thermal Data: Comprehensive heat dissipation profiles and discharge curve data available for aerospace simulation upon request.
These cells must be stored within a 3.0V to 4.3V open-circuit voltage range to prevent irreversible capacity loss. Operating or storing outside the -20°C to 60°C temperature window may induce electrolyte degradation and internal short-circuit risk.
- Voltage Window Compliance: Maintain cell voltage between 3.0V and 4.3V during storage and operation to avoid over-discharge or over-charge damage.
- Charge Rate Limitation: Do not exceed a 0.5C charge rate to prevent lithium plating and thermal runaway.
- Thermal Exposure Restriction: Avoid exposure to temperatures above 60°C or below -20°C to preserve electrolyte stability and separator integrity.
- Short-Circuit Prevention: Keep terminals insulated during handling and storage to prevent external short circuits that can cause rapid overheating.
- Mechanical Integrity: Do not puncture, crush, or deform the cell casing to avoid internal short circuits and electrolyte leakage.
What is the cycle life trade-off for the EC02 series at 490Wh/kg under a 3C continuous discharge profile?
The EC02 series cells deliver a cycle life of ≥50 cycles at room temperature when cycled at 0.2C charge and 3C discharge, reflecting the inherent trade-off between ultra-high energy density and cycle longevity. This specification is explicitly stated for both the 3Ah and 15Ah variants, confirming that the 490Wh/kg density is achieved with a limited cycle life suitable for mission-critical, short-duration HALE deployments rather than high-cycle applications.
Can the EC02 series cells be integrated into existing UAV battery management systems without custom BMS engineering?
No, the EC02 series requires specialized BMS engineering for low-charge/high-discharge cycles typical of high-altitude operations, as noted in the product's customization section. The cells operate within a voltage range of 3.0V to 4.3V and a maximum charge rate of 0.5C, necessitating a tailored management protocol to ensure safe and efficient performance under the extreme weight and discharge demands of HALE platforms.
What are the storage and handling requirements for the EC02 series solid-state cells to maintain performance at -20°C?
The EC02 series cells are rated for an operating temperature range of -20°C to 60°C, but no specific storage or handling protocols beyond standard aerospace-grade precautions are detailed in the product description. To preserve the 490Wh/kg energy density and ensure reliable 3C discharge at low temperatures, users should follow general solid-state cell guidelines, including avoiding deep discharge below 3.0V and storing at moderate temperatures, though the manufacturer does not provide explicit storage conditions.
The EC02 series solid-state cells achieve a peak energy density of 490Wh/kg, making them ideal for HALE UAVs and stratospheric aircraft where weight is critical; however, the cycle life of only 50 cycles and a 0.5C charge rate impose operational constraints for programs requiring frequent reuse.
Positive
- Ultra-High Energy Density of 490Wh/kg: Delivers industry-leading energy-to-weight ratio of up to 490Wh/kg, enabling unprecedented flight endurance for weight-constrained HALE UAVs.
- Optimized for HALE Mission Profiles: Specifically designed for high-altitude long-endurance operations with stable 3C continuous discharge, supporting extended mission durations.
Trade-offs
- Limited Cycle Life of 50 Cycles: Cell life is rated at only 50 cycles under standard test conditions (0.2C charge/3C discharge at RT), significantly shorter than conventional lithium-ion cells, necessitating frequent replacement for long-duration programs.
- Slow Maximum Charge Rate of 0.5C: Maximum charge rate is limited to 0.5C, requiring longer recharge intervals compared to higher-rate cells, which may impact mission turnaround logistics.
