B & Plus K.K. has started selling a product compatible with 12S batteries as a new model of its 500W wireless charging system for drones.
This product adopts a wireless power transfer method that automatically starts charging simply by landing, realizing the unmanned operation of industrial drones.
Features of this product
- Automatic charging just by landing the drone (500W output)
- Supports up to 10cm of positional misalignment
- Compatible with 12S batteries
- Lightweight structure (1100g)
It achieves both a lightweight design and a tolerance for up to 10cm of misalignment. Furthermore, by supporting applications for the Radio Law (high-frequency utilization equipment), it lowers the hurdle for on-site implementation.
Background and Challenges
Challenges of charging in drone operations
As the use of drones advances, the need for long-hour operations and unmanned operations is increasing.
Furthermore, their use is expanding in various fields such as agriculture, disaster prevention, infrastructure inspection, and research applications, and there are different operational needs for each application.
In fields like the following, there is a growing demand for continuous operations and unmanned systems.
Among these, "charging" remains a major challenge.
Conventionally, manual battery replacement and charging work were required, which acted as a barrier to fully automated operations.
"Unmanned charging" has become an important factor in drone operations.
Product Overview
Wireless charging that works just by landing
This product's wireless charging realizes the "automation of charging" in drone operations.
It employs a wireless power supply method that automatically begins charging when the drone lands, eliminating the need for cable connections or human intervention.
By completing the charging process without human hands, it supports the unmanned operation of drones.
This contributes to the automation and labor-saving of drone operations by enabling continuous operation through automatic charging, handling outdoor environments, and improving safety.
Compatible with 12S batteries to support high-output drone operations
Drones have battery configurations such as 4S, 6S, and 12S, which are used depending on the aircraft size and application.
In recent years, with higher output and advanced functionality, an increasing number of drones are adopting 12S batteries.
The 12S battery (12 cells) is a high-voltage specification with a nominal voltage of 44.4V and approx. 50.4V when fully charged. Because it can supply the same output at a lower current, it enables efficient power supply while minimizing heat generation and energy loss.
Particularly in large drones used for agricultural or logistics applications, high-voltage 12S batteries are often adopted as they require increased payload capacity and support for prolonged operations.
To accommodate the spread of these high-output drones, this product supports charging with 12S batteries, making it applicable to a wide range of drone operations, including large aircraft.
Achieves both lightweight design and misalignment tolerance
In drone applications, weight reduction is a crucial factor in terms of flight time and payload capacity.
Wireless charging equipment, in particular, tends to cause weight increases, posing a challenge for practical application.
This product secures an allowable performance for up to 10cm of misalignment while realizing a lightweight design of approx. 1100g.
Compared to general wireless charging for AGVs (misalignment of 1-2cm) or products specialized for lightweight drones (approx. 5cm), it has a design that balances lightweight properties with misalignment tolerance.
Product Specifications and Features
Lineup and specification comparison
B & Plus offers multiple wireless charging models tailored to various applications.
In addition to the environmentally resistant models for AGV/AMRs and models for drones that pursue lightness, this product was developed as a new lineup that emphasizes a balance between lightness and misalignment performance.
As a model focused on balancing weight and misalignment tolerance, this product has specifications suitable for automated drone operations.
Stable charging control
Wireless charging for drones is still a developing field, and the manufacturers working on commercialization and practical application are limited.
In general wireless charging, while only the maximum output is emphasized, there are cases where the actual power fluctuates significantly in real operational environments due to the influence of charging distance and misalignment.
Additionally, regarding weight, only partial configurations may be evaluated, leading to a weight increase for the overall system.
Our product adopts a structure integrating the charging head and control amplifier, realizing stable power transmission within the range of distance and misalignment.
This enables highly reliable charging in actual operations.
Also compatible with BMS control units
A BMS unit for battery control is available as an option, enabling highly safe charging control. The total weight when equipped with the BMS is approx. 1300g.
Compliant with Radio Law (High-frequency utilization equipment) applications
This product is compliant with the application for high-frequency utilization equipment under the Radio Law, ensuring safe operation.
