Accessories & Customization
BMS Integration: Optimized for smart management systems requiring precise high-rate discharge monitoring and thermal control.
Custom Form Factors: Bespoke cell dimensions and tab orientations are available for specialized research and industrial integration.
Technical Data: Full discharge curve sets and safety testing documentation are available upon verified inquiry.
The ES03 series solid-state cells require strict adherence to electrical and thermal operating limits to prevent performance degradation or safety hazards. These cells must be handled with care to avoid short circuits given their ultra-low internal resistance and should be operated within the specified temperature range of -20°C to 60°C and discharge rate of 3C.
- Operating Temperature: Operate the cell only within the -20°C to 60°C temperature range to maintain safety and performance.
- Discharge Rate: Do not exceed the continuous discharge rate of 3C to prevent overheating and capacity loss.
- Short Circuit Prevention: Avoid short circuits by ensuring proper insulation and handling, as the ≤1mΩ internal resistance can produce high fault currents.
- Thermal Management: Ensure adequate heat dissipation during operation to keep temperature rise below 30°C for long-term cell health.
- Mechanical Integrity: Protect the cell from mechanical puncture or deformation to prevent internal short circuits.
This procedure outlines the safe handling and initial deployment steps for the ES03 series solid-state cells. Following these steps minimizes risk of short circuits and ensures operation within specified limits.
Required Equipment: BMS (Battery Management System), Temperature monitoring system
- Inspect
Inspect the cell for any physical damage, deformation, or leakage before handling. - Connect
Connect the cell to a BMS that supports high-rate discharge monitoring and thermal control. - Verify
Verify that the ambient temperature is within the -20°C to 60°C operating range before initiating discharge. - Monitor
Monitor the cell temperature continuously during operation and ensure the rise stays below 30°C above ambient.
How does the ES03 series achieve a balance between 340 Wh/kg energy density and 3C continuous discharge without compromising cycle life?
The ES03 series uses a solid-state architecture that harmonizes high energy density with power output. The cell maintains a cycle life of ≥500 cycles at 1C/3C charge/discharge under room temperature, while delivering ≥95% of state of charge at 3C continuous discharge. This trade-off is enabled by an ultra-low internal resistance of ≤1 mΩ at 30% SOC, which minimizes energy loss and thermal stress during high-rate cycling.
What BMS integration requirements are critical for the ES03 solid-state cell given its ≤1 mΩ internal resistance and 3C discharge capability?
The ES03 cell requires a smart BMS capable of precise high-rate discharge monitoring and thermal control to exploit its low internal resistance and 3C discharge. The system must also manage the cell's temperature rise of <30°C during heavy operation, which is within the -20°C to 60°C operating range. Optimized BMS integration ensures safe and efficient energy extraction across the 36 Ah and 39 Ah capacity variants.
What thermal management characteristics does the ES03 series exhibit under high-rate discharge in UAV or robotics applications?
The ES03 series maintains a temperature rise of less than 30°C during heavy operation, even at its 3C continuous discharge rate. This low thermal rise preserves cell health and system safety under the -20°C to 60°C operating temperature range. The solid-state design and ≤1 mΩ internal resistance minimize heat generation, making the cell suitable for enclosed or thermally constrained platforms like professional UAVs and industrial robots.
The ES03 series solid-state cell delivers a balanced 340Wh/kg energy density with 3C continuous discharge and ≤1mΩ internal resistance, but its 500-cycle life at 1C/3C is moderate, and the 10.5mm vs 11.5mm thickness difference between the 36Ah and 39Ah variants requires careful mechanical integration.
Positive
- Balanced High Energy and Power Density: The ES03 series achieves 340Wh/kg energy density alongside 3C continuous discharge capability, meeting the demands of high-performance UAV and robotics applications without sacrificing power output.
- Ultra-Low Internal Resistance for Efficiency: With ≤1mΩ AC internal resistance at 30% SOC, the cell minimizes energy loss and heat generation during high-rate discharge, improving overall system efficiency and thermal behavior.
Trade-offs
- Moderate Cycle Life of 500 Cycles: The cell is rated for 500 cycles at 1C charge/3C discharge at room temperature, which may be a limiting factor for applications requiring extended operational lifespan beyond this threshold.
- Cell Thickness Variation Between Capacity Options: The 36Ah and 39Ah variants have different thicknesses (10.5mm vs 11.5mm), requiring careful mechanical design and validation to ensure proper fit and thermal management in the intended enclosure.
