Best Guide to IP67 Robot Charging Stations: How to Build Weatherproof Power Docks for Outdoor and Mobile Robots

As mobile robots expand into outdoor logistics, last-mile delivery, agriculture, and perimeter security, the demand for rugged, weatherproof charging stations has never been higher. These bots operate day and night, through storms, dust, and fluctuating temperatures—so their charging infrastructure must be just as resilient. The solution? IP67-rated robot charging stations, engineered to deliver safe, efficient power in challenging environments.

IP67-rated systems provide full protection against dust and temporary water immersion, making them ideal for sidewalks, warehouses, parking structures, farms, and more. But building a charging dock that truly meets the IP67 standard requires more than a sealed box—it demands an integrated approach combining mechanical design, thermal engineering, and smart power electronics.

This guide walks engineers, OEMs, and systems integrators through the critical steps in designing and deploying IP67-compliant robot charging stations—from spec sheets to real-world field success.

Why IP67 Certification Is Essential for Outdoor and Mobile Robot Charging

FAQ

What is an IP67 robot charging station?

An IP67 robot charging station is a weatherproof, dust-tight, and water-resistant charging dock designed to support outdoor or industrial robots. The IP67 rating ensures protection against complete dust ingress (6) and temporary immersion in water up to 1 meter for 30 minutes (7). These docks include sealed enclosures, waterproof connectors, and conformally coated internal electronics. They’re ideal for robots operating in rain, snow, dust, and other harsh environments, such as delivery, surveillance, cleaning, and agricultural bots.

What makes IP67 different from IP68 in charging systems?

Both IP67 and IP68 provide excellent water and dust protection, but IP68 is for longer or deeper immersion. While IP67 protects against rain or splashes, IP68 is designed for submersion beyond 1 meter, depending on manufacturer specifications. IP68 is typically used for underwater or flood-prone applications. However, IP67 is more common and sufficient for most outdoor robot charging needs. It’s a balance between robust protection and design flexibility, whereas IP68 often requires fully sealed, pressure-resistant enclosures and stricter thermal controls.

What components need to be IP67-rated in a robot charger?

Key components that must meet IP67 standards include:

• Enclosure housing (sealed, UV-resistant)

• DC output connectors (with gaskets or sealing caps)

• Cable entry points (with compression glands)

• PCB and power modules (with conformal coating or potting)

• Vents or membranes (that allow airflow but block water)

If any one part fails to meet IP67, the entire system is at risk of water ingress or short circuit. For this reason, engineers must design holistically, not just select an IP-rated box.

How do I test if a charging station meets IP67?

IP67 compliance is tested using dust chambers and immersion tanks, as per IEC 60529. Dust testing verifies no ingress under vacuum, and water testing involves submersion at 1 meter for 30 minutes. Engineers must ensure no internal moisture or functional degradation occurs after testing. Certification should be conducted by an accredited third-party lab, and test documentation should include performance data. Some OEMs also conduct field simulations, such as power-washing or humidity cycling, to ensure real-world durability.

Can Phihong USA help design and certify IP67 charging stations?

Yes. Phihong USA offers a full portfolio of IP67-rated power components, including sealed power supplies, outdoor connectors, surge protection, and thermal solutions.
