Our intelligent BMS extends battery life by 30% in the same form factor.
Exceed industry standards with our S-Tier Safety Testing Protocol for total compliance.
Fit powerful, custom batteries into award-winning designs with our miniaturization expertise.
Electronic Shelf Labels operate in a unique micro-power environment, requiring years of dormant standby punctuated by sudden, high-current pulses for RF communication (BLE/Zigbee) and screen updates. Standard commercial batteries often suffer from severe voltage sag under these dynamic loads, leading to premature device failure. At Himax, our lithium cells are meticulously tailored to overcome these exact IoT power bottlenecks.
Our specialized ESL battery solutions deliver:
By isolating the specific power demands of retail communication protocols, we help IoT manufacturers eliminate battery replacement bottlenecks and achieve true “deploy-and-forget” reliability.
→ Consult our engineering team for a pulse-discharge profile analysis tailored to your ESL architecture.
Retail deployments subject IoT devices to a surprising spectrum of environmental stress, from the humid aisles of fresh produce to the freezing temperatures of cold-chain storage. Himax batteries are chemically engineered to maintain electrochemical stability regardless of ambient fluctuations.
Key environmental resilience features include:
We supply comprehensive environmental stress-testing data, streamlining your product certification process for international markets.
→ Request our temperature-cycling test reports for cold-chain IoT applications.
One of the most critical failure points for standard ESLs occurs in supermarket freezers. At -20°C, conventional battery internal resistance spikes, causing the voltage to drop below the threshold required to refresh an E-ink display. Himax’s wide-temperature lithium solutions bypass this physical limitation entirely.
Performance advantages in extreme retail zones:
Our targeted thermal chemistry guarantees that your digital pricing remains accurate and responsive, even in the harshest cold-chain storage.
→ Ask for our low-temperature discharge simulation data for freezer-grade ESLs.
The evolution of ESL technology—shifting toward thinner profiles, larger multi-color displays, and integrated LED flashers—demands power sources that break away from standard footprints. Himax scales custom engineering from rapid prototyping to high-volume manufacturing.
Customization parameters include:
We operate as an extension of your R&D lab, delivering power modules that dictate the physical sleekness of your next-generation labels.
→ Send us your PCB layout constraints for a customized thin-cell structural proposal.
Rolling out an ESL system across a national supermarket chain requires tens of thousands of flawless battery units delivered on rigid schedules. Our manufacturing ecosystem is built for uncompromising volume and consistency.
Key production capabilities:
This systematic rigor drastically lowers procurement risks and guarantees uniformity across your entire distributed retail network.
→ Contact us to audit our automated micro-battery production lines.
Navigating the regulatory complexities of shipping large quantities of lithium batteries is critical for global IoT providers. We manage the entire logistics pipeline, ensuring your assembly lines remain constantly fed.
Our specialized logistics services include:
→ Discuss your annual rollout volumes and global delivery requirements with our supply chain experts.
Q1: What battery chemistry is optimal for Electronic Shelf Labels?
Lithium-ion pouch cells (Li-Po) and Lithium-Manganese (Li-MnO2) are ideal. They offer the necessary high energy density and low internal resistance to support the peak pulse currents required by E-ink displays and BLE modules.
Q2: Can your batteries operate in supermarket freezers?
Yes. We engineer wide-temperature lithium cells specifically formulated with low-temperature electrolytes, ensuring reliable pulse discharge and display updates even at -20°C in cold-chain environments.
Q3: How do you achieve a 5+ year lifespan?
We achieve multi-year lifespans by utilizing high-purity raw materials and precision manufacturing that minimizes microscopic internal short circuits, resulting in a self-discharge rate of less than 2% per year.
Q4: Do you offer custom sizes for ultra-thin ESL enclosures?
Absolutely. We specialize in bespoke ultra-thin pouch cells (down to 1.5mm thickness) tailored precisely to fit the internal cavities of slim, modern electronic pricing labels.
Customer Background & Application Needs
The client is a premier European retail technology integrator specializing in complete IoT store infrastructures, deploying millions of Electronic Shelf Labels across multinational supermarket chains.
A critical operational bottleneck emerged in their freezer sections. Their existing standard batteries suffered from severe internal resistance spikes at -20°C. When the ESL requested a pulse current to update the E-ink price tag, the voltage crashed, resulting in blank screens, failed wireless syncs, and manual pricing errors that violated strict EU consumer laws.
Key requirements:
• Stable high-current pulse capability precisely engineered for -20°C environments to drive screen refreshes.
• Ultra-low self-discharge ensuring a minimum 5-year maintenance-free lifespan in cold storage.
• Ultra-thin pouch configuration to fit seamlessly within their sleek, next-generation IP67 waterproof label enclosures.
