Truyền tải điện không dây là gì và tại sao nó quan trọng?

Khi công nghệ hiện đại phát triển, những phát triển mới có đủ hình dạng và kích cỡ khác nhau. Một trong những đổi mới đó là truyền tải điện không dây. Sự tiến bộ này là bước tiếp theo từ việc sạc thường xuyên cần có dây. Khi thị trường điện không dây cất cánh, sức sống của nó cũng tăng theo. Khu vực không dây này cũng đi kèm với những ưu và nhược điểm nhất định. Với tầm với và tính thực tế, các chuyên gia tin rằng truyền tải điện không dây sẽ tiếp tục thay đổi thế giới công nghệ. Những người khác đồng ý, nhưng tuyên bố rằng nó phải vượt qua các trở ngại như an ninh và can thiệp trước khi đạt được tiềm năng đầy đủ của nó. Bất kể, loại công nghệ này là đột phá này là gì, nó chỉ mới bắt đầu.

Truyền tải điện không dây

Câu hỏi đầu tiên để giải nén là khái niệm này là gì. Truyền năng lượng không dây là việc truyền năng lượng điện đến từ nguồn điện và đến một thiết bị điện – và nó không có dây. Những thứ sử dụng công nghệ này hàng ngày bao gồm lò vi sóng, tấm pin mặt trời và bộ sạc không dây. Các nguồn này sử dụng nguyên lý công suất cảm ứng để tạo ra truyền dẫn không dây, bắt đầu bằng hai cuộn dây.

First, there is the transmitter. Then, there is the receiver. These components are both two coils within the different technology which act similarly to inductors. The charger converts the main voltage into an alternating current, which should be high-frequency for best performance. Then, it transfers the current to the transmitter coil and produces a magnetic field. The receiver coil in the device picks up that magnetic field through a process called resonance, which amplifies the current.

When the coils resonate at the same frequency, they increase the capacity for more energy transfer. With enough resonance, they can operate without physical contact. This process is wireless charging power transfer.

Why This Technology Is Important

Wireless charging is becoming one of many emerging technologies that disrupt the status quo in favor of more efficient operations. As a result, it will overtake regular charging that requires a wire. You can bet this shift will most likely happen within the next decade.

Wireless charging is important because of its versatility and applications. From cars to watches to phones, this form of charging affects all devices. Now standard for some phones, the demand will only continue to grow. It provides more accessibility, as well, since households and businesses can incorporate this charging into their tables or other objects and not worry about the cords that come with it.

As this technology becomes widespread, it will pave the way for new tech in the future. Right now, wireless charging is groundbreaking, but it will eventually lead to updates and improvements society has never seen before.

The Advantages

Several benefits come with wireless power transfer. The progression of society into a more technological future is one of them. However, other areas of improvement include manufacturing, practicality and maintenance.

First, without a wire, production necessities will decrease. People will have less need for cords, which will help declutter. Going wireless entails a better-sealed device that can prevent damage. People will also spend less on replacing wires — a chore everyone is all too familiar with.

Integration will also improve how society uses wireless charging. Cars are working toward wireless charging as the demand for sustainability increases. Certain restaurants or coffee shops already offer this form of power transfer for phones right from the table or bar.

Wireless charging allows better reach from the transmitter to the receiver, so charging and using a device will be easy. Still, while it does provide high-speed charging, it’s slower than wired charging. Experts predict the technology will outpace wired charging in the future, however.

The Disadvantages

If wireless charging is to become disruptive, it will need to overcome some disadvantages first. They range from initial investment to security issues.

Right now, the initial cost of wireless charging is high. It will deter people from buying since wired charging is cheaper. This price will likely drop as wireless charging becomes more widespread, but for now, it remains costly.

Interference and long-distance prove to be another impediment. Some wireless charging requires that the device is on a pad or station to work. With others, the farther away the gadget is, the less the charging works. Potential interference from other wireless power transfer devices may get in the way as well.

Though experts believe wireless charging has similar levels of radiation as regular methods, people will need to know that it’s okay, as many are afraid of radiation. Security could be a problem, too. Any form of wireless transfer makes devices susceptible to security breaches.

Real-Life Examples of Wireless Power Transfer

Despite the cons, people love wireless charging, especially with phones and wearables. This technology also affects the medical industry and warehousing.

Medical implants, like pacemakers, can use wireless charging just like a watch. Industry workers can use it for sensors in warehouses to keep up maintenance and security. Elsewhere, Starbucks and IKEA are examples of where wireless charging is a hit. Tables in specific Starbucks locations provide wireless charging, and IKEA customers can find furniture with built-in wireless charging capabilities.

Wireless power transfer is only going to grow. For now, sit back, relax and charge your phone wirelessly.
