PKNERGY lithium battery solutions for traffic signal sensor systems

In the age of smart cities, intelligent traffic signal sensors play a critical role in optimizing road safety and reducing congestion.

These systems continuously monitor vehicle flow, pedestrian crossings, and environmental conditions to adjust signal timings dynamically.
To operate seamlessly 24/7, each sensor node requires a stable, efficient, and long-lasting power source—a demand perfectly met by
PKNERGY’s advanced lithium battery technologies.As a custom lithium battery manufacturer, PKNERGY provides

customized lithium battery packs

and

LiFePO₄ battery solutions

tailored for outdoor control cabinets, smart poles, and distributed sensor networks that support intelligent transportation systems.

1. The Need for Reliable Power in Smart Traffic Networks

Traffic signal sensors are often deployed at intersections and along highways where direct power access may be limited or unstable.
Short-term blackouts or low-voltage conditions can disrupt synchronization across the network, leading to inefficiencies or safety risks.
Incorporating a custom lithium battery pack ensures uninterrupted operation during power outages, maintenance, or communication delays.

Unlike conventional batteries that degrade quickly under continuous cycling, lithium-based energy systems maintain consistent performance
over thousands of cycles. This reliability is essential for infrastructure operating around the clock and for cities looking to reduce
maintenance visits and replacement costs.

For intersections that also integrate cameras or vehicle-detection radars, PKNERGY can combine traffic sensors with

small energy storage systems

to provide robust backup for both sensing and communication equipment.

2. PKNERGY’s Battery System Specifications

Typical PKNERGY solutions for smart traffic sensor networks include:

Voltage Range: 12V, 24V, or 48V systems configurable by load
Capacity Range: 20Ah – 200Ah modular designs
Battery Chemistry: LiFePO₄ for high safety and long lifespan
Cycle Life: > 6000 cycles @ 25°C, 80% DOD
BMS Integration: Active balancing, over-voltage, and thermal protection
Communication: CAN / RS485 interface with real-time SOC reporting

The compact, modular architecture allows easy installation within existing control cabinets or pole-mounted enclosures,
ensuring minimal maintenance and flexible system expansion. For projects that require cabinet-level integration or hybrid
power (grid + solar), PKNERGY can deliver complete

energy storage system (ESS) solutions

matched to the sensor network topology.

3. Key Benefits of PKNERGY Lithium Battery Packs

By switching from traditional lead-acid batteries to PKNERGY LiFePO₄ systems, cities and integrators gain multiple advantages:

Continuous uptime: guarantees smooth sensor-to-controller data transmission even during grid interruptions.
High energy efficiency: reduces recharge frequency, improving system availability and lowering operating costs.
Durability: resistant to vibration and minor mechanical shock at intersections and on poles.
Eco-friendly chemistry: free of heavy metals, compliant with CE and RoHS standards.
Scalability: supports both standalone sensors and fully networked intersections.
Long service life: > 6000 cycles significantly extend replacement intervals compared with lead-acid batteries.

For projects that demand custom size, connector, or communication protocols, PKNERGY offers full

custom LiFePO₄ battery pack design

to match your traffic controller manufacturer and cabinet layout.

4. Real-World Deployment Example

A municipal client in Southeast Asia integrated PKNERGY’s 48V 100Ah LiFePO₄ battery systems into a new smart traffic corridor.
The sensors collected real-time data on vehicle density and transmitted it wirelessly to the city’s central management platform.

The batteries sustained 36 hours of autonomous operation per node, maintaining full communication stability during grid interruptions.
Maintenance frequency was reduced by 60%, improving overall operational efficiency and helping the city maintain stable traffic
signal performance during storms and scheduled power cuts.

6. FAQ: Traffic Signal Sensor Battery Systems

Q1: How do I choose the right voltage and capacity for my traffic sensor system?

Start from the rated voltage and power consumption of the traffic controller and sensor devices.
PKNERGY commonly provides 12V, 24V, and 48V LiFePO₄ battery packs with 20–200Ah capacity.
Our engineering team can help calculate required backup time and design the optimal configuration.

Q2: Can these batteries support both wired and wireless communication nodes?

Yes. The battery system only provides DC power; it is fully compatible with both wired and wireless communication modules.
In addition, the BMS can communicate via CAN or RS485 to share SOC and alarm information with your monitoring platform.

Q3: Are PKNERGY LiFePO₄ batteries suitable for high-temperature outdoor environments?

PKNERGY LiFePO₄ batteries are designed for outdoor cabinet applications with appropriate ventilation or air
conditioning. For particularly hot climates, we can adjust the cell selection and BMS temperature protection strategy
to ensure safe long-term operation.

Q4: What certifications can you provide for government or public tenders?

PKNERGY batteries come with UN38.3, IEC62619, CE, and MSDS documentation. Additional reports and test data can be supported
according to the requirements of local standards or project tenders.

Q5: Can you customize the battery pack size and connector layout for our cabinets?

Yes. We offer OEM/ODM services including enclosure design, terminal location, and waterproof connectors, ensuring that
the battery pack can be easily integrated into your existing traffic controller cabinets.
