Custom Battery Packs for Tunnel & Infrastructure Lighting
🔋 Reliable, Smart, and Durable Backup Power Solutions for Critical Lighting Systems
Infrastructure lighting systems — including tunnel luminaires, underpass lighting, and utility corridor fixtures — demand exceptional reliability and service life. PKNERGY’s custom lithium battery packs are designed specifically to ensure these systems stay illuminated under any condition, minimizing downtime and maintenance costs.
🚧 The Challenge of Tunnel and Infrastructure Lighting
Tunnel and infrastructure lights are often installed in hard-to-reach areas and expected to perform continuously for years. These systems face:
- ⚙️ Irregular power conditions and unstable grid voltage
- ⏱️ Limited service access and long maintenance intervals
- 💡 Need for backup illumination during grid loss
- 🌐 Integration with smart control and monitoring networks
🔋 Why Custom Battery Packs Matter
Standard off-the-shelf batteries often can’t meet the specific requirements of critical lighting applications. PKNERGY’s custom-designed battery packs provide:
- ⚡ Tailored runtime & performance: Designed to match specific LED wattage and backup requirements.
- 🔩 Optimized form factor & mounting: Fits within luminaires or remote cabinets seamlessly.
- 🧠 Smart BMS diagnostics: Real-time monitoring for SoC, SoH, and fault reporting via RS-485 or Ethernet.
- 🧰 Serviceability: Quick-swap modules simplify field replacement.
- 🏗️ Durability: Ruggedized for vibration, dust, and temperature resistance.
🏞️ Application Example: Tunnel Lighting Backup System
For a highway tunnel lighting manufacturer, PKNERGY developed a 48V, 8kWh custom battery pack supporting a 500W LED load for 10 minutes at full brightness, followed by 100W for 20 minutes. This pack includes:
- 🔋 Integrated LiFePO₄ cells with BMS protection
- 🌡️ Active thermal management and pressure relief
- 📶 RS-485 / Ethernet communication for remote monitoring
- ⚙️ Compact quick-mount structure for easy luminaire integration
🏗️ Benefits to Infrastructure Operators and OEMs
- ✅ Assured uptime: Reliable emergency illumination ensures safety compliance.
- 📊 Smart control: Remote SoC/SoH data enhances predictive maintenance.
- 💰 Reduced service cost: Modular design lowers replacement and inspection time.
- 🌍 Lifecycle efficiency: Extended lifespan reduces total cost of ownership.
- 🧠 System compatibility: Fully integrates with smart lighting networks.
🧩 Design & Engineering Best Practices
- 📈 Define backup runtime and LED duty-cycle accurately.
- 🧰 Plan mechanical layout and service access early in design.
- 🔋 Choose optimal cell type, BMS, and communication interface.
- 🌡️ Validate temperature, humidity, and vibration performance.
- 🧠 Incorporate predictive diagnostics for proactive maintenance.
🛡️ Safety & Compliance
PKNERGY’s infrastructure lighting batteries comply with UN38.3, IEC62133, CE, and RoHS standards, ensuring export-ready quality and operational safety across global markets.
✅ Conclusion
In tunnel and infrastructure lighting, reliability and uptime are critical. A custom-engineered battery pack enhances safety, reduces maintenance, and supports long-term infrastructure efficiency. PKNERGY’s experience in smart lighting and industrial energy systems empowers OEMs and operators to deliver smarter, safer, and more sustainable illumination.
