WIRELESS CHARGING IN THE NEWS
Driven by the "dual carbon" goals, the installed capacity of photovoltaic power stations has soared, but the power generation efficiency loss caused by pollution such as dust shielding and bird droppings accumulation is as high as 15% to 30%.
In harsh scenarios such as high-voltage substations, underground cable tunnels, and extremely cold transmission lines, power inspection robots are the "silent sentries" ensuring the safety of the power grid. However, problems such as spark hazards, interface corrosion, and low-temperature failure caused by traditional plug-and-pull charging have made the "battery life anxiety" of robots a fatal shortcoming restricting intelligent inspection.
Today, with the rapid development of intelligent manufacturing and smart logistics, AGV forklifts, as the "intelligent workers" in the material handling process, their continuous operation capabilities directly determine the production capacity ceiling of enterprises.
In recent years, with breakthroughs in artificial intelligence, sensors and bionic technology, quadruped robots, with their flexible movement capabilities and adaptability to complex terrains, are moving from laboratories to industrial sites.
Companies like Toyota Material Handling and KION Group have integrated inductive charging into their AGV forklifts. In one case study, a German automotive plant reduced charging-related downtime by 40% after deploying wireless systems.
AGVs and AMRs equipped with inductive receivers can charge during brief idle periods—for example, while waiting at pick-up stations or during scheduled pauses. Small, frequent charging cycles extend uptime and reduce the need for large, heavy batteries.
These methods disrupt operations, limit scalability, and incur maintenance expenses. In contrast, inductive charging addresses these issues by enabling fully autonomous, contactless energy transfer.
The technology has evolved significantly since its early applications in consumer electronics (e.g., smartphones). Today, high-power inductive systems can deliver energy efficiently (85–95% efficiency rates) at power levels exceeding 20 kW, making them viable for industrial equipment like AGVs.
Enter inductive charging, a wireless power transfer technology that eliminates these bottlenecks and unlocks new levels of efficiency for AGV/AMR fleets. This article explores the principles of inductive charging, its applications in AGV/AMR forklifts, and the transformative benefits it brings to modern warehouses and factories.
In high-voltage substations, urban pipe galleries and chemical industrial parks, rail-mounted inspection robots are like "intelligent guardians" in the steel veins, safeguarding the safety of energy lifeblood 24 hours a day.
In the wave of intelligent manufacturing and smart logistics, automated guided vehicles (AGVs) have become the "blood vessels" of modern factories, undertaking core tasks such as material handling and production line connection.
With the surging demand in fields such as Marine resource development, environmental monitoring and national defense security, autonomous underwater robots (AUVs) have become the core tools for deep-sea exploration.
