Technical Standards and Certification

In the rapidly evolving field of drone technology, adhering to technical standards and certifications is essential for ensuring the reliability and safety of your industrial drone battery. These standards guide manufacturers in developing high-performance batteries that meet the demands of various applications.

Performance Thresholds: C-Rate & Power Stability

When selecting an industrial drone battery, understanding the C-rate is crucial. The discharge rate determines the lithium battery’s ability to release energy per unit of time. The Continuous C-rating determines the stability of the power output during normal flight. For high-payload industrial applications, such as agricultural plant protection drones, a discharge rate of 30C or higher is required. The calculation formula for the Maximum Discharge Current is Capacity × C-Rating , which must be greater than 1.2 times the drone’s maximum operating current. High energy density (Wh/kg) is also a key metric, as it reflects the amount of energy the battery can store per unit of weight, providing longer endurance at the same weight.

Procurement Validation: Load & Endurance Testing

Before you invest in a battery, professional procurement requires thorough acceptance testing.

• Load Discharge Test: Attach external equipment (e.g., a camera) to simulate actual flight scenarios and observe for “sudden power drops” (e.g., charge suddenly jumping from 30% to 10%). Sudden drops are a typical sign of poor cell consistency, which can easily lead to flight accidents.

• No-Load Endurance Test: Record the actual flight time, deducting a 20% safety margin from the manufacturer’s stated endurance. If the gap exceeds 30%, it indicates capacity misrepresentation or severe cell degradation.

• Visual Inspection (Asset Acceptance): Perform a “visual inspection” upon receiving the battery. If there is slight swelling or deformation when gently squeezing the casing, reject it immediately. Inspect the electrode contacts; oxidation, blackening, or corrosion suggest the battery may have been subjected to long-term over-discharge or electrolyte leakage. Check the production date; the optimal service life is within 1 year of the production date, and batteries older than 2 years may have lost 10% or more of their capacity, even if new.

Reliability: Certification & Wide-Temperature

Reliability is paramount in drone operations, requiring adherence to both international certifications and environmental adaptability.

• Key Certifications: Essential certifications include UN38.3 (International Transport Safety Certification) and CE (European Safety Certification).

• Operating Temperature Range and Performance: Industrial drones require batteries engineered to sustain reliable discharge performance in extremely low-temperature environments, specifically down to -30℃. Conversely, for safety, the battery must incorporate an over-temperature protection function that automatically cuts off power when the ambient temperature exceeds 60℃.

• Water Resistance: Batteries with a waterproof rating of IP64 or higher can effectively handle light rain.

Safety: BMS Protection Thresholds

A robust Battery Management System (BMS) is critical for preventing thermal runaway and ensuring safe operation. The BMS must possess precise safety protection features:

• Overcharge Protection: When the battery voltage reaches 4.25V ± 0.05V, the BMS will rapidly cut off the charging circuit to prevent overheating or explosion.

• Over-discharge Protection: When the battery voltage drops to 2.8V ± 0.05V, the BMS will immediately cut off the discharge circuit to prevent permanent capacity loss.

• Temperature Monitoring and Protection:

  • Over-Temperature Cutoff: When the ambient temperature exceeds 60℃, the battery must have an over-temperature protection function, which automatically cuts off power.

  • Low-Temperature Management: When the battery is in a low-temperature environment (e.g., -20℃), the BMS will automatically start the preheating function.

• Short Circuit Protection: The BMS must respond in an extremely short time (less than 100 microseconds) to cut off the circuit.

• Cell Balancing: The Cell Balancing function ensures that the voltage and charge of each cell in the battery pack remain consistent.

This robust reliability, coupled with a high cycle life (500-800 cycles), reduces the need for frequent replacements, thereby lowering the TCO. By optimizing asset safety and reducing potential costly downtime, you can allocate resources more effectively, thereby optimizing Operational Expenditures (OPEX).

Asset Durability and Maintenance Strategy

Maintaining the durability of your UAV batteries is essential for maximizing their lifespan and ensuring optimal performance, significantly minimizing the Total Cost of Ownership (TCO). Mastering correct usage methods can prolong the life of battery assets and safeguard enterprise investment returns.

Maintenance: Periodic Calibration

Periodic calibration of your UAV batteries is crucial for maintaining performance and restoring cell consistency.

• Calibration Frequency: Perform a “complete charge-discharge cycle” using a dedicated battery tester after every 20 charges. This cycle involves discharging the battery to 3.0V/cell, then fully charging it.

• Calibration Benefit: This procedure helps restore cell consistency, reducing the cell voltage difference to within 0.05V, and can extend the battery’s life by 10%-15%.

• Charging Management: Do not charge beyond 90% each time to prevent overcharge lithium plating. Control the charging ambient temperature between 10°C and 35°C..

Lifespan: Cycle Count & Asset Durability

Understanding and managing the battery’s lifespan is vital for effective asset management.

• Cycle Life: High-quality industrial batteries, such as Herewin’s solution, are engineered for durability, with a cycle life that can reach 500 to 800 cycles before capacity degrades to 80%. This significantly lowers the Total Cost of Ownership (TCO).
