Custom Lithium Battery Solutions for Cold-Chain Refrigerated Containers
High-Reliability Li-ion / LiPo / LiFePO4 Power Systems for Global Reefer Logistics
1. Introduction
The global cold-chain logistics industry is growing rapidly due to rising demand for fresh food, pharmaceuticals, vaccines, and biological materials requiring strict temperature control.
From maritime shipping to long-haul trucking, refrigerated containers (“reefers”) must maintain stable temperatures for days or weeks—often operating in harsh, high-vibration, wide-temperature environments.
To ensure uninterrupted performance, onboard systems—data loggers, IoT sensors, GPS trackers, cooling controllers, alarm modules, and backup cooling systems—depend on highly reliable lithium batteries.
PKNERGY provides cold-resistant, shock-resistant, and certified lithium battery solutions engineered for -30°C to +60°C reefer environments.
2. Application Background
Refrigerated containers rely on multiple electronic systems, including:
- Temperature & humidity data recorders
- GPS / Beidou / Iridium tracking modules
- BLE / Wi-Fi / LTE communication gateways
- Reefer control units
- Door and lock sensors
- Backup power for cooling
- Security and alarm systems
Key challenges:
- Extreme temperatures (-30°C to +60°C)
- 30–90 days long-duration operation
- High vibration from trucks, ships, cranes
- Salt fog & corrosion
- Strict international certification requirements
