Is It Time to Rethink How We Power Mobile Robots? Why AMRs and AGVs Need a Charging Revolution

Autonomous Mobile Robots (AMRs) and Automated Guided Vehicles (AGVs) are transforming warehouses and distribution centers with improved efficiency, flexibility, and scalability. But one critical question remains: how do we keep these tireless machines powered without disrupting operations?

With the market for mobile robots in intralogistics, last-mile delivery, and mobile picking projected to reach approximately $150 billion by 2044, energy management is emerging as a key bottleneck. The challenge has sparked a vital conversation: is it time to rethink how we power our mobile fleets?

The answer is yes. While inductive charging has long been the default approach, a new alternative—capacitive charging—is proving to be a game-changer. It promises to fundamentally reshape energy delivery for AMRs and AGVs.


The Limits of Inductive Charging: A Roadblock to Efficiency

Inductive charging brought early promise with features such as:

  • Wireless power delivery without direct contact.

  • Durability in dusty or humid conditions.

  • Hands-free automation for charging cycles.

But in today’s high-throughput, dynamic facilities, the limitations of inductive systems are becoming more pronounced:

  • Precision Alignment Requirements: Inductive systems demand exact positioning between the pad and receiver. In busy warehouse environments, misalignment is common, especially with AGVs following fixed routes.

  • Charging Interruptions: Even slight misalignment can reduce power transfer or halt it entirely, leading to unnecessary downtime.

  • Safety Hazards: The generation of eddy currents around metal can cause excessive heating—posing risks in metal-heavy environments.

These limitations directly affect operational uptime, productivity, and safety—making inductive charging less practical for modern mobile automation.


The Rise of Capacitive Charging: A New Paradigm

Capacitive charging introduces a new energy model—one that is flexible, safer, and more aligned with real-world industrial needs. Key advantages include:

  • Misalignment Tolerance: Capacitive systems allow for power transfer even when robots are not perfectly aligned. This provides a critical edge in dynamic or unpredictable environments.

  • Energy-On-the-Go: Capacitive charging can support power delivery during brief stops or slow movement—keeping robots within an energy-positive range without halting workflows.

  • Enhanced Safety: Capacitive systems do not generate magnetic fields that interact dangerously with surrounding materials.

The result: improved uptime, lower total cost of ownership, and greater overall reliability for mobile fleets.


CaPow’s Power-in-Motion: The Shift Is Underway

CaPow’s Genesis platform, powered by Power-in-Motion technology, represents a breakthrough in energy delivery. Rather than forcing robots to stop for traditional charging, CaPow enables energy transfer while in motion or en route, eliminating charging downtime entirely.

Key benefits include:

  • Maximized Fleet Utilization: Robots stay within an optimal energy range, operating without planned interruptions.

  • Smaller Fleets, Lower Costs: No need for 20–30% extra backup robots to compensate for downtime.

  • Facility Efficiency: Modular floor antennas eliminate the need for charging areas—reclaiming floor space for operations.

  • Reduced Battery Dependency: Minimizes deep discharge cycles, extending battery lifespan and lowering environmental impact.


Conclusion: A Smarter, More Scalable Energy Model

The shift is clear: warehouses can no longer afford outdated charging paradigms. As robotic fleets expand, the drawbacks of inductive systems become more costly—both operationally and financially.

Capacitive, in-motion energy delivery—like CaPow’s Power-in-Motion—is the new benchmark. It ensures energy is available where and when it’s needed, without compromising throughput, safety, or floor space.

It’s not just a new way to charge. It’s a new way to think about energy.
