Introduction

Air-conditioned clothing (ACC) is becoming essential for workers in high-temperature environments such as construction, logistics, outdoor maintenance and manufacturing. As demand increases in the U.S., Japan, Southeast Asia and Europe, the battery system behind these wearable cooling jackets must provide safety, light weight, and long runtime for daily industrial use.

PKNERGY designs custom lithium battery packs specifically optimized for wearable cooling systems, ensuring comfort, reliability, and long-term durability.

Power Needs of Air-Conditioned Clothing

Air-conditioned clothing integrates micro-fans, control modules and smart sensors. To maintain stable airflow and safety, the battery system must deliver:

• Stable voltage output: typically 7.4V (2S) or 12V (3S)
• Long runtime: 6–12 hours per charge
• Lightweight pack for wearable comfort
• High cycle life for daily industrial usage
• Certified safety for global consumer markets

Key engineering challenges include heat resistance, compact size limitations, long-duration operation, and continuous outdoor performance.
