USV Battery Selection Guide: Endurance, Safety & Reliability Are Key
How to Choose the Optimal Power Battery for Unmanned Surface Vehicles (USVs)
USVが海洋調査、環境モニタリング、セキュリティパトロールなどに広く採用されるようになるにつれ、その中核となる電源であるバッテリーの適切な選択が重要になってくる。バッテリーの種類によって、耐久性、安全性、環境適応性が大きく異なります。このガイドでは、最適なバッテリーを選択するための専門的な洞察を提供します。
Core Requirements for USV Batteries
USVs demand batteries with exceptional performance for prolonged aquatic operations:
高エネルギー密度: Ensures extended endurance, minimizing recharge/replacement needs
Water & Corrosion Resistance: Withstands humid, saline environments
Stable Discharge: Prevents voltage drops that could disrupt operations
Lightweight Design: Reduces vessel load and enhances maneuverability
Comparison of Main USV Battery Types
| バッテリータイプ | Pros | Cons | Best For |
| LiFePO₄ | High safety, 2000+ cycles, heat-resistant | Lower energy density, poor cold performance | Long-endurance missions, deep-sea exploration |
| NMC/NCA | High energy density, cold-resistant | Safety risks, shorter lifespan (800-1200 cycles) | High-speed USVs, short-duration tasks |
| Solid-State (Emerging) | Ultra-high energy density, leak-proof | High cost, limited commercialization | Future premium USVs |
3. 5 Key Factors for USV Battery Selection
(1) Endurance: Match Energy Density & Capacity
Calculate daily power consumption; select 1.5x redundancy.
For long missions (e.g., ocean monitoring), prioritize high-density LiFePO₄ (180Wh/kg+).
(2) Water & Corrosion Resistance
Choose IP67+ rated enclosures to prevent water damage.
Opt for salt-spray-resistant coatings for marine environments.
(3) Temperature Adaptability
Cold climates (e.g., polar research): Select low-temperature LiFePO₄ (-30°C operable).
Hot climates (e.g., equatorial zones): Ensure active/passive cooling systems.
(4) Safety & Reliability
バッテリー管理システム（BMS） is mandatory for overcharge/discharge protection.
Verify UN38.3, CE, UL certifications.
(5) Brand & After-Sales Support
Prioritize established brands or USV-specialized manufacturers.
Demand 2+ years warranty そして remote diagnostics.
Conclusion
USV batteries require balanced consideration of endurance, environmental resilience, and safety. Select battery types based on operational scenarios and partner with proven suppliers for reliable performance.
