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).

以iPhone为例，要实现接触式无线充电，必须将无线充电环插入珍贵的iPhone机身。为了保证充电效率，充电环的尺寸一般不小，大多以牺牲电池容量为代价。到了iphone12这一代，也加入了磁铁，进一步占据了机身空间。

Take the iPhone as an example, in order to realize the contact wireless charging, the wireless charging ring must be inserted into the precious iPhone body. In order to ensure the charging efficiency, the size of the charging ring is generally not small, mostly at the expense of the battery capacity. To the iPhone 12 this generation, also joined the magnet, further occupied the fuselage space.

在energous官方网站和小米空间电荷的微博上，我们没有找到任何关于空间电荷辐射的解释。

In the tweets on energous's official website and Xiaomi's space charge, we did not find any explanation on the radiation of space charge.

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.

哪些方面最容易被察觉？有哪些商机？

Which aspects are most easily perceived? What business opportunities are there?

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.

家里的插孔、插座基本消失，空分充电变送器可直接融入装修。在商场、公园和办公楼附近，可能会有和基站一样多的空分充电发射机，另一个万亿级的市场已经出现。

The jacks and sockets at home have basically disappeared, and the air separation charging transmitters may be directly integrated into the decoration. Near shopping malls, parks and office buildings, there may be as many air separation charging transmitters as base stations, and another trillion level market has emerged.

新能源汽车可能完全取代燃油汽车，因为主干道上铺设了空分充电发射器，车辆在行驶过程中不断充电，从不断电。

New energy vehicles may completely replace fuel vehicles, because the trunk roads are paved with air separation charging transmitters, and the vehicles are charging while they are moving and never power off.

最大的变化是'电'的概念消失了，可能会被另一个词取代。""触电"和"来电"可能会让年轻人感到越来越陌生。

The biggest change is the disappearance of the concept of "electricity", which may be replaced by another word. "Electric shock" and "incoming call" may make young people feel more and more strange.

顺便说一句，从长远来看，共享电源银行可能会成为一个夕阳产业，一个我们这些"老人"在真正的无线时代喜欢谈论的过去。

By the way, in the long run, shared power bank may become a sunset industry, a past that we "old people" like to talk about in the era of real wireless.

空间电荷？让我们看看

Space charge? Let's see

当我们得知空分收费已达到"可用"标准时，公司集团里传出了几个开心的笑话。

When we learned that the air separation charging had reached the "usable" standard, a few happy jokes came out of the company group.

楼上邻居：家里有孕妇，请关掉空间费，谢谢合作。

Upstairs neighbor: there is a pregnant woman at home, please turn off the space charge, thank you for your cooperation.

楼下邻居：家里有高考生，请开间收费，我们要网上上课，你要是考不上清华就得负责。

Downstairs neighbor: there are college entrance examination students at home, please open the space charge, we want to online class, you have to be responsible if you can't pass the Tsinghua exam.

小区物业：注意，注意，周六下午5点，小区花园里有商家在做活动。现场可免费充电1小时，功率10W。

Community property: Notice, notice, there are businesses doing activities in the community garden at 5 p.m. on Saturday. They can charge for 1 hour free of charge at the scene, and the power is 10W.

30：爸爸，任天堂有一个新的50W空气快速充电虚拟现实大脑机。如果不能收费，还可以给你一款价值5000元的游戏。

After 30: Dad, Nintendo has a new 50W air fast charging VR brain machine. If it can't charge, it will also give you a game worth 5000 yuan.

妻子：来吧！从家到贵公司，充电功率只能充50%。如何解释额外的30%和它在哪里？！

Wife: come on! From home to your company, the charging power can only charge 50%. How to explain the extra 30% and where is it?!

我们这一代人：那时候，我们不得不专门为手机开一个洞，用充电头拖着长长的线给手机充电。哦，顺便说一下，你在虚拟博物馆里看到了手机。是的，是的，就是这样。为了给子孙后代留下一个绿色的环境，我们害怕它，节约充电头。

Our generation: back then, we had to specially open a hole for mobile phones and use a charging head to drag a long line to charge mobile phones. Oh, by the way, you saw mobile phones in the virtual museum. Yes, yes, that's the thing. In order to leave a green environment for future generations, we are afraid of it and save the charging head.

如果以上几段真的发生了，那就证明无线时代真的来了。

If the above paragraphs really happen, it proves that the wireless era is really coming.
