This charge is not possible for 500 watts. Generally speaking, the power of wireless charging is relatively low, the power is usually between 5 watts and 15 watts, if the power of wireless charging is increased to 500 watts, it will produce high electromagnetic radiation, which will have adverse effects on human health. At the same time, it will also produce high heat, causing fire and other safety hazards.
It is the first generation of mobile phone wireless charging, and the technology is mature, but it can only be single-to-single short-range charging (qi standard, within 1cm, within 5 watts), and can not be similar to WiFi single-to-multiple charging.
Qi wireless charging system consists of a base station and mobile devices, the base station is the charging base we often see, the mobile device is the mobile phone through the principle of electromagnetic induction charging base on the magnetic induction coil to convert electrical energy into electromagnetic waves, the magnetic induction coil on the back shell of the mobile phone then converts electromagnetic waves into electrical energy to charge the battery.
HUAWEI FreeBuds 3 supports wireless charging with up to 2W power.
Once it comes to wireless charging, it can't avoid transformationThe problem of efficiency. Based on electromagnetic induction wireless charging, the theoretical charging efficiency reaches 80%. But this is only the theoretical efficiency, the actual situation must be discounted. According to the online test data, in the case of 220 AC V, open 30W wireless VOOC flash charge, the charging terminal output power is as high as 462W, which is much lower than 80% conversion efficiency. This presents a problem of power consumption.
First, wireless charging technologyEfficiency is too low, high-power application, efficiency is a very important problem, such as the charger output a total of 100J of energy, but finally received only 50J, then 50% of the energy is wasted. The current efficiency of wireless charging technology is about so much, so it is unlikely to be used in high power anytime soon.
Low efficiency: energy storage and transmission efficiency is not as good as real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power. Although wireless charging can be unplugged, the distance between the phone and the charger is very small. But the loss of electromagnetic energyThe amount is still not small, the power received by the general mobile phone is about 75% of the power sent by the charger.
The charge efficiency is not high. Once the distance is a little far away, the efficiency of charging will be dramatically reduced, and a lot of time and resources need to be wasted to complete the charging, so the use is not meaningful. Safety issues in the charging process. High-power wireless charging equipment will produce a large amount of electromagnetic radiation, which will cause certain adverse effects on health, but also have interference effects on aircraft and communications. The first practical aspect.
The power of wireless charging now reaches more than 50 watts is still very few, because there is noLine charging and space charging is not the same, wireless charging is just to cancel the line, you put the phone on the dedicated wireless charger, it can be charged, but to tell the truth, the different charging technology on the market now, its charging technology is not the same, even if the high charging power, it is not necessarily faster than the low charging power, which contains a lot of water.
To sum up
Although its volume is simple, the function is powerful, a charge can meet the needs of three devices, thanks toEfficient support for Qi wireless charging technology. Although specific charging power and time data are not yet available, according to the previous Wireless Charger Duo Pad can reach 12W wireless charging capacity, we have reason to believe that the Trio Pad performance will be even better. In terms of pricing, it is expected to be around $100, which is similar to the previous game.
