Mid-range wireless charging uses electromagnetic fields to transfer power over a distance without direct contact, allowing devices to charge without being physically connected to a charger.
It operates by generating an alternating electromagnetic field through a transmitter coil, which is then received by a corresponding receiver coil in the device, converting the energy back into electrical power for charging.
Mid-range wireless charging can power various devices, including smartphones, laptops, low-power autonomous mobile robots, lawn mowers, and feeding robots.
The range can vary depending on the system, but it generally covers distances from a few centimeters to tens of centimeters (typically 2 cm to 40 cm).
Mid-range wireless charging offers greater convenience by eliminating cables and connectors. However, it may have different efficiency levels, as well as dynamic usage scenarios, compared to wired methods.
While mid-range wireless charging is continually improving, it may be slightly less efficient than wired charging due to energy loss in the transfer process.
Yes, some systems are designed to charge multiple devices simultaneously, depending on their configuration and power output.
Modern systems are designed with safety features to prevent overheating, overcharging, and electromagnetic interference, ensuring safe operation.
Yes, there are ruggedized systems specifically designed to operate reliably in outdoor or harsh environments.
Charging systems can be embedded into furniture or built into various structures, providing convenient and seamless access to power.
Benefits include reduced cable clutter, increased convenience, improved safety, and the ability to charge devices autonomously.
Limitations can include reduced efficiency over longer distances and potential interference with the presence of metal objects in the transmission path.
Properly designed systems minimize any potential negative impact on battery life, charging the on vehicle battery at a “shallow” state (70% – 90%) to extend the battery life. Avoiding battery overheating through frequent and smaller charging periods.
Higher frequencies generally enable longer power transfer distances due to increased coil quality factor. However, a much more complicated system design and considerations to be taken is expected due to parasitic inductance, capacitance and resistance are involved.
Key factors influencing power efficiency include coil size, material and design, operating frequency, alignment tolerance, distance between coils, and quality factor of the circuit components, etc. Environmental conditions such as mechanical material and design can also impact efficiency.
No, because we are currently using a different standard that supports only short distances.
Mid-range wireless charging systems generally require low maintenance. Unlike systems with physical connectors that need frequent plugging and unplugging, wireless power systems minimize wear and tear, reducing the need for maintenance.
Some systems may support upgrades or expansions, such as firmware updates through over-the-air (OTA) methods.
Balancing these factors is crucial because it ensures the system meeting application’s requirements with its optimal performance while minimizing energy waste and extending the operational range. Effective design enhances overall system reliability and user experience.
To ensure safety regarding human exposure, we conduct FCC and CEE-related tests on our products. These tests help to verify that the systems meet all safety standards and regulations, ensuring they are safe for use.
