Xiaomi suddenly released the space charging technology, and the mobile phone has said goodbye to the anxiety of battery life?

现实生活的发展似乎比小说世界的发展要快得多。前天，小米正式发布了空间隔离充电技术，并宣布在小米11上率先实现。

The development of real life seems to be much faster than that of the novel world. The day before yesterday, Xiaomi officially released the space isolation charging technology, and announced that it was the first to realize it on Xiaomi 11.

无线时代来临了吗？

Is the wireless age coming?

空间电荷的作用是什么？

What's the effect of space charge?

综上所述，亮点如下：

To sum up, the highlights are as follows:

真正的无线充电

Real wireless charging

充电半径可达数米，移动充电，边充边玩

Charging radius up to several meters, mobile charging, play while charging

单设备最高5W，也可支持多设备5W同时充电（未指定最大设备数）

Single device up to 5W, can also support multi device 5W charging at the same time (does not specify the maximum number of devices)

不怕被异物覆盖（异物的厚度和材质没有规定）

Not afraid to be covered by foreign matters (the thickness and material of foreign matters are not specified)

隔离充电的概念并不新鲜

The concept of isolated charging is not new

这是一项"老技术"，让沉闷的长数字圈掀起了关于小水雾空间隔离充电的讨论。

It's an "old technology" to make the long dull digital circle stir up discussion about the space isolation charging of small water spray.

早在2015年，远程无线充电技术的初创企业energous就提出了"释放你的能量"的概念，并发布了RF-to-DC整流芯片的概念样本。预计该设备将通过Wi-Fi和蓝牙低功耗技术从2.4GHz供电至2.5GHz或5.8GHz，在蓝牙发现要充电的设备后，它将以射频为核心自动为设备充电。它声称，在未来，它可以无线充电设备的最大功率为10W的间隔15英尺（457.2厘米）。

As early as 2015, energous, a start-up of long-distance wireless charging technology, proposed the concept of "release your power" and released the concept sample of RF to DC rectifier IC. It is expected that the device will be powered from 2.4 GHz to 2.5 GHz or 5.8 GHz through Wi Fi and Bluetooth low-power technology After Bluetooth finds out the device to be charged, it focuses on RF to charge the device automatically. It claims that in the future, it can charge the device wirelessly with a maximum power of 10W at an interval of 15ft (457.2cm).

另一个信息可以作为参考。2017年，美国能源公司第一代无线充电发射机wattup mid field通过美国联邦通信委员会认证。理论上满足辐射暴露值的相关要求。各国对电子产品的辐射暴露值都有严格的控制，市场上的产品在理论上都符合安全标准。

Another information can be used as a reference. In 2017, the wattup mid field, the first generation of wireless charging transmitter of energy company, was certified by the Federal Communications Commission of the United States. In theory, it meets the relevant requirements of radiation exposure value. All countries have strict control on the radiation exposure value of electronic products, and the products on the market meet the safety standards in theory.

然而，即使科学证明辐射对人体无害，在可预见的未来，隔离充电发射机可能面临与WiFi、有线耳机、无线耳机和信号基站一样的阻力，辐射将成为其挥之不去的祸根。

However, even if it is scientifically demonstrated that the radiation is harmless to human body, in the foreseeable future, the isolated charging transmitter may face the same resistance as WiFi, wired headphones, wireless headphones and signal base stations, and radiation will become its lingering curse.

对于电子设备制造商来说，这是一个营销难点，特别是在无线充电发射机推广的初期，辐射剂量信息的宣传和产品安全性的证明可能是营销的重中之重。

For electronic equipment manufacturers, this is a marketing difficulty, especially in the early stage of the promotion of wireless charging transmitter, the publicity of radiation dose information and the proof of product safety may be the top priority of marketing.

想象一下真实的无线世界

Imagine the real wireless world

小说《三体》生动地描述了现实的无线世界

The novel three bodies gives a vivid description of the real wireless world

罗骥指着空中的车流说："看那些飞车。他们用燃料还是电池？"大石摇了摇头。"不，地球上的石油已经被抽出来了，那些汽车不需要电池。它们一直在飞。他们永远不会缺电。我要买一个。""这是你对科技奇迹的麻木。人类有无限的能量。就像盘古在开拓世界！现在你还没意识到这是多么美好的时光

Luo Ji pointed to the traffic in the air and said, "look at those flying cars. Do they use fuel or batteries?" Dashi shook his head. "No, the oil on the earth has already been pumped out, and those cars don't need batteries. They just keep flying. They'll never run out of electricity. I'm going to buy one." "This is your numbness to the miracle of technology. Mankind has unlimited energy. It's just like Pangu's opening up the world! Now you don't realize what a great time it is

Energous相信，该技术的未来广告可以在家庭、办公室、医疗咨询室、工厂、交通和军事环境中大规模使用。数码产品、智能穿戴、智能家居、医疗器械、生产机械、汽车等项目都可能在未来实现这一技术。

Energous believes that the future advertising of the technology can be used on a large scale in home, office, medical consulting room, factory, transportation and military environment. Digital products, smart wear, smart home, medical devices, production machinery, automobiles and other items may be able to realize the technology in the future.

电子产品没有充电口。今后，手机盒里就不会有充电头了。可能没有充电线。家用空分充电发射机可替代无线充电板，成为"互联网红色产品"。

There is no charging port for electronic products. In the future, there will be no charging head in the mobile phone box. Probably there will be no charging wires. The household air separation charging transmitter may replace the wireless charging board and become a "Internet red product".

当你带着手机回家时，手机一收起来就开始自动充电。第二天你到公司的时候也是这样。手机基本上是全充电。

When you come home with your mobile phone, it starts to charge automatically as soon as you put it away. The next day when you arrive at the company, it's the same. The mobile phone is basically in full charge.
