Introduction

Smart parking systems are rapidly transforming urban infrastructure. Parking space detectors play a critical role by delivering real-time occupancy data, improving traffic efficiency and user experience.
At the core of these detectors is a dependable power source. For modern smart city deployments, lithium batteries have become the industry standard due to their stability, energy density, and long service life.

Power Requirements of Parking Space Detectors

Parking space detection devices are usually installed outdoors and expected to operate autonomously for years.
Their power systems must support long-term standby, ultra-low power consumption, and stable voltage output for sensors and wireless modules.

• Continuous operation in outdoor environments
• Low-power sensing with periodic wireless transmission
• Long service life with minimal maintenance
• Stable performance across temperature variations

Frequent battery replacement is impractical and costly, especially in large-scale smart parking or
industrial automation battery systems.

Why Lithium Batteries Are the Preferred Choice

Lithium-based batteries offer multiple advantages that align perfectly with IoT-powered parking detection systems:

• High energy density enabling compact device design
• Low self-discharge for extended standby periods
• Excellent cycle performance for repeated sensing and communication
• Reliable voltage output for wireless and sensing modules

Compared with traditional primary batteries, lithium solutions significantly reduce maintenance frequency and lifetime operating costs in
consumer electronics
and smart city deployments.

Typical Battery Configurations

Battery configuration depends on enclosure size, communication frequency, and expected service life.
Common solutions include:

• Single-cell lithium-ion batteries for moderate energy requirements
• Lithium polymer batteries for ultra-compact and space-constrained designs
