Application Background

Highway enforcement cameras are a critical component of modern intelligent transportation systems (ITS). They are widely used for speed detection, license plate recognition, red-light enforcement, and traffic flow analysis. These systems are typically deployed on gantries, poles, or roadside infrastructure and must operate continuously in outdoor environments.

From a technical perspective, the battery is not merely a power source but a core subsystem that directly affects system uptime, data integrity, and long-term maintenance cost.

Engineering Challenges

• Continuous 24/7 operation under extreme temperatures
• Stable high-voltage output for imaging and communication modules
• Compact installation space in pole-mounted or cabinet designs
• Long service life with minimal maintenance
• High reliability to avoid data loss or system downtime

PKNERGY 48V 1.5Ah Battery Solution

PKNERGY provides a custom-engineered 48V 1.5Ah lithium battery pack specifically designed for highway enforcement camera systems. The solution is based on high-quality Li-ion cells configured in a 13S structure to deliver stable and reliable high-voltage output.

• Nominal Voltage: 48V
• Capacity: 1.5Ah
• Optimized energy density for compact enclosures
• Low internal resistance for stable discharge

BMS and Protection Design

A customized Battery Management System (BMS) is integrated to ensure safe and reliable operation. The BMS includes overcharge, over-discharge, overcurrent, and short-circuit protection, along with cell balancing and NTC temperature monitoring.

This design ensures stable power delivery during peak loads such as night-time infrared illumination and data transmission bursts.

Mechanical & Environmental Adaptation

The battery pack is designed to fit compact camera housings and pole-mounted cabinets. PKNERGY supports custom dimensions, industrial-grade connectors, vibration-resistant internal structures, and optional waterproof or dustproof enclosures.

Wide-temperature design ensures reliable long-term outdoor operation.

Certification & Compliance

For infrastructure and government projects, compliance is essential. PKNERGY battery solutions support UN38.3, MSDS, and CE / IEC62133 certifications upon request, simplifying global deployment and system integration.

Value for System Engineers and Project Managers

• Stable high-voltage lithium power system for industrial cameras
• Custom battery pack design aligned with system architecture
• Reliable rechargeable performance for 24/7 operation
• Reduced maintenance frequency
• Lower total cost of ownership

Case Study: Highway Speed Enforcement Camera Project

PKNERGY supplied a 48V 1.5Ah lithium battery pack for a multi-site highway speed enforcement project. The system achieved stable outdoor operation, reduced maintenance intervals, and improved overall system uptime, leading to successful pilot deployment and volume production.

Conclusion

Stable and reliable battery systems are essential for highway enforcement cameras. PKNERGY’s 48V 1.5Ah lithium battery solution delivers high-voltage stability, long service life, and engineering-grade reliability for intelligent transportation applications.
