Battery ** can not be delayed

Israel’s StoreDot has developed a new technology that allows the phone to be fully charged within 30 seconds.

Yufy Review:

When I first saw this news, I was like many users. The first thing I felt was a surprise. As a user of smart phones and tablets, the most worrying thing is that the battery is not very durable. Take the mobile phone as an example, if it is used more frequently The full battery can't be supported during the day, and the charging time is long. It usually takes two or three hours to fully charge the battery. Being able to fill the phone for 30 seconds should be a dream for many people.

But when you calm down, you can't help but be suspicious of this technology. It feels somewhat contrary to our basic knowledge. According to the limited physical knowledge grasped by Xiao Bian, the world’s energy is conserved. To charge the battery is to convert AC power into electricity and store it in the battery. The battery power is fixed, and the charging voltage is fixed. It is necessary to shorten the charge. Time, can only increase the charging current. Take the fast pop-up mobile phone OPPO Find7 as an example. The 3000mAH battery adopts a 5V 4.5A super power charger to increase the mobile phone power from 10% to 70%, which takes about half an hour. By shortening this time to one minute, it is difficult to imagine the extent to which the charging current needs to be large. Such large current charging generates large amounts of heat, and it is feared that cooling down is a big problem.

Xiaobian sees their description of the next-generation battery on the StoreDot official website. It says that full charge will be calculated in minutes rather than hours, plus the video was released on YouTube on March 31st. The video type is comedy, combined with the previous technology. Analysis, Xiao Bian also tend to believe that some people's analysis, 30 seconds fast charge may be just a "jokes" this year's April Fool's Day only. Such a "joke" has been reproduced by major media, showing that people are eager to charge at a high speed, and the battery revolution cannot be delayed.

In fact, engineers have also been trying to increase the charging speed. Just like the OPPO Find7 mentioned above, they increased the number of battery interfaces from the traditional 4 or 5 to 8, corresponding to this, OPPO Find7's The interface of the dedicated charging line is also 7-pin. At the same time, the current control chip is integrated on the charger and the main board of the mobile phone respectively. In this way, 5V 4.5A and half-hour fast charging can be realized, and the current charging current of the mainstream mobile phone is only 1A. In addition, fast-charge device Voltissimo, which was introduced by Japan's peripheral manufacturer Buffalo, and mobile phone-speed-charge technology that NTT DoCoMo's Japan displayed, are also used to increase the charging current.

Xiao Bian believes that the 30-second speed charge may be really a "joke" at present, but people want to achieve the dream of real-time charging is true, can solve the fever problem of high current charging, this dream may not be far away.
