Battery-Free Locking Solution

In an era where sustainability and operational efficiency drive business decisions, traditional battery-powered locks are becoming a liability. From dead batteries in critical moments to the recurring cost of replacements and environmental waste, the limitations of conventional electronic locks are impossible to ignore. Enter the battery-free locking solution—a breakthrough in access control that harnesses energy harvesting technology to deliver truly maintenance-free security. At KERONG, with over 24 years of R&D and manufacturing experience, we have pioneered batteryless electronic locking systems that are transforming industries from smart offices and gyms to medical facilities and logistics hubs. With 10 million+ locks sold globally and partnerships with top-tier smart locker operators, our battery-free technology is setting a new standard for reliability, sustainability, and cost-efficiency.

What Is a Battery-Free Locking Solution?

A battery-free locking solution is an advanced access control system that operates without internal batteries by harvesting energy from ambient sources or user interactions. These systems typically utilize two core technologies:

1. NFC Energy Harvesting

By utilizing the electromagnetic field generated by a smartphone or NFC credential, energy is harvested to power the smart lock electronics. For example, Infineon's NFC energy-harvesting chip can draw 20–50 mW from the phone's NFC field, providing sufficient power to unlock the mechanism—no physical keys, codes, or battery replacements required.

2. Kinetic Energy Harvesting

Our electronic passive locks convert mechanical motion—such as inserting and turning an electronic key—into electrical energy. This "1 key to manage 10,000 locks" approach offers a robust, wire-free solution for industrial applications where connectivity is limited.

Key Insight: Battery-free locks eliminate the need for battery replacements, avoiding downtime and reducing labor costs while preventing issues caused by insufficient battery power, such as lock malfunctions.

Why Industries Are Switching to Battery-Free Smart Locks

Zero Maintenance Costs

Traditional electronic locks require regular battery replacements, leading to significant ongoing expenses and operational disruptions. Battery-free locks are maintenance-free from day one. Once installed, they operate indefinitely without technician callouts, battery purchases, or disposal logistics.

Unmatched Sustainability

Every year, billions of disposable batteries end up in landfills, contributing to e-waste and environmental degradation. By eliminating batteries entirely, KERONG's solutions align with corporate sustainability goals and the environmental initiatives of modern smart cities. This isn't just good for the planet—it's a powerful statement for your brand's ESG commitments.

Enhanced Security & Reliability

Battery-powered locks are vulnerable to power depletion, leaving assets inaccessible or unsecured. Battery-free locks, conversely, are always ready. Our systems employ advanced authentication technology, including NFC data exchange and key-chip communication with high-strength encryption, to prevent unauthorized access. Additionally, tamper-resistant designs withstand rigorous use and potential threats.

Performance in Extreme Environments

Unlike battery-powered alternatives that fail in low temperatures or harsh conditions, KERONG's battery-free locks function normally in extreme environments. Whether it's a freezing outdoor locker or a high-humidity medical storage cabinet, reliability is never compromised.
