In the context of Industry 4.0, AGVs (Automated Guided Vehicles) serve as the "logistics blood vessels" of smart factories, and their continuous operation capabilities directly determine production efficiency. However, the traditional contact charging method requires AGVs to frequently shut down, resulting in task interruption, complex scheduling, and even affecting stability due to battery life attenuation. The emergence of high-power wireless charging technology, through contactless and high-energy-density power transmission, has become a key breakthrough in solving this pain point.

Technical advantages are compatible with AGV scenarios

Seamless charging, zero interruption of tasks

High-power wireless charging (such as magnetic resonance technology) enables AGVs to automatically replenish energy during loading and unloading or short stays without the need for manual intervention. For instance, the AGVs at Tesla's Gigafactory are equipped with wireless charging boards at material transfer points, with a charging power of 30kW. A 5-minute charge can support 2 hours of operation, enabling "charging while working".

2. Extend battery life and reduce maintenance costs

Traditional plug-and-pull charging accelerates battery aging due to frequent charging and discharging, while wireless charging can increase battery cycle life by more than 30% by intelligently regulating current and voltage (such as CATL's dynamic equalization charging algorithm).

3. Flexible deployment to adapt to complex scenarios

The wireless charging module can be embedded in the ground or at the bottom of the shelf to avoid the interference of traditional charging piles on path planning. The Bosch factory in Germany has deployed invisible charging areas in narrow passageways. When AGVs pass through, they automatically trigger charging, increasing space utilization by 20%.

Application case

In the automotive manufacturing sector, a certain car manufacturer has adopted a 50kW wireless fast charging system, increasing the average daily operation time of AGVs from 18 hours to 23 hours and reducing the logistics delay rate by 60%.

In the e-commerce warehousing scenario, JD Asia No.1 Warehouse has achieved 24/7 operation of AGVs through wireless charging, increasing the daily sorting volume by 45%.

High-power wireless charging technology redefines the energy management model of AGVs through "contactless energy replenishment", providing underlying support for flexible production in Industry 4.0. In the future, as the charging efficiency exceeds 90% and the cost drops, it will become a standard technology for AGVs.
