Powering Intelligent Traffic Control – PKNERGY Custom Lithium Battery Solutions for License Plate Recognition Systems
Reliable, long-life lithium battery packs designed for outdoor automatic license plate recognition (ALPR) cameras
and controllers in smart city traffic projects.
Among these, Automatic License Plate Recognition (ALPR) systems have become a cornerstone of smart city infrastructure.
They enable law enforcement, toll collection, and parking automation by capturing and processing license plate information
in real time. A crucial component that ensures uninterrupted operation of these systems is the battery pack powering cameras,
controllers, and communication modules.As an experienced custom lithium battery manufacturer, PKNERGY provides
customized lithium battery packs and LiFePO₄ battery solutions
that are optimized for outdoor, 24/7 ALPR and traffic monitoring applications.
1. Power Challenges in ALPR Deployments
ALPR devices are often installed in outdoor or semi-remote environments such as highways, parking entrances,
or restricted zones. Power interruptions caused by unstable grid supply or harsh conditions can result in
data loss and system downtime. A reliable, high-efficiency battery solution is therefore essential to
maintain continuous operation, especially when solar or hybrid power sources are used.
Traditional sealed lead-acid batteries cannot meet the requirements of compact size, fast charging, and
long cycle life demanded by ALPR units. They are bulky, heavy, and typically need more frequent replacement,
increasing the total cost of ownership.
PKNERGY’s lithium-ion and
LiFePO₄ battery packs
provide a superior alternative for both stationary and mobile recognition devices, particularly when
integrated with solar-powered or DC UPS-based systems.
2. Recommended Battery Solutions for License Plate Recognition
PKNERGY develops customized lithium battery packs specifically engineered for low-voltage control systems
and camera-based electronics. For license plate recognition equipment, typical configurations include:
- Nominal Voltage: 12.8V or 25.6V LiFePO₄ system
- Capacity Range: 10Ah to 100Ah depending on power design
- Continuous Discharge Current: up to 2C for high-speed image capture
- Cycle Life: > 4000 cycles at 80% DOD
- Protection Level: IP65–IP67 optional for outdoor enclosures
Each pack integrates smart BMS (Battery Management System) to manage cell balancing, temperature monitoring,
and communication via RS485 or CAN protocols. This ensures the battery operates safely with consistent
voltage output and reliable data exchange with the ALPR controller.
For integrators who need complete system-level support, PKNERGY also offers
energy storage system solutions
that can be adapted to small-scale ALPR power cabinets or roadside energy boxes.
3. Advantages of PKNERGY Lithium Batteries for ALPR
Compared with traditional lead-acid batteries, PKNERGY lithium batteries provide multiple advantages
that are critical for license plate recognition projects:
- Compact and lightweight: enabling flexible installation in poles or roadside boxes.
- Fast charging efficiency: reaching 80% capacity in less than 2 hours, ideal for
solar-powered or intermittent grid environments. - Long service life: over 10 years of typical field operation at recommended DOD.
- Maintenance-free: no need for periodic electrolyte checks or frequent replacements.
- Wide compatibility: supports hybrid solar + grid systems and DC UPS configurations.
- High reliability: smart BMS protection against overcharge, over-discharge, over-current,
and abnormal temperature conditions.
These advantages help city operators and system integrators enhance uptime, reduce onsite maintenance visits,
and improve overall project ROI.
4. Integration Example: Highway ALPR Surveillance Project
PKNERGY recently provided a 25.6V 50Ah LiFePO₄ pack for a regional highway surveillance project.
Each battery powered four ALPR cameras and one edge-processing unit with 24-hour autonomy.
During a 12-month trial period, the system achieved 98% uptime, outperforming the
previous sealed lead-acid battery system by a factor of three in operational lifespan. The new lithium
solution also reduced field maintenance frequency and minimized unexpected downtime caused by
battery failures.
For future projects, PKNERGY can tailor battery capacity, communication protocol, and mechanical design
to match specific ALPR hardware and environmental conditions.
