Today to share Zhenjiang high-power wireless charging program knowledge, which will also explain the Zhenjiang radio special equipment factory, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Mobile phones use wireless charging, you need to buy a wireless charging base or wireless charging back case to use. Connect the charger to the wireless charging base, and then place the phone or a phone with a wireless charging back case on the wireless charging base. Take off the holster if the phone holster is tooThick or non-original charging holster, may affect the charging effect, it is recommended to remove the holster after charging attempt.
Huawei p40 Wireless charging Method Huawei wireless charging only for some mobile phones have this function, not all mobile phones have. This section describes how to enable and operate Huawei p40 wireless charging. Turn on wireless charging First, tap on [Settings] on the desktop of your phone.
This article will give you a detailed introduction to the whole process of millet 11 wireless charging, so that you can easily open the wireless charging mode. Check whether your phone supports wireless charging first, open "Settings" and go to "Battery.With performance, look for the "Wireless charging" option. If you see it, it means that your Mi 11 has wireless charging superpowers! Choose Qi standard charger Secondly, choose a wireless charger that is in line with Qi standard.
Methods for wireless charging a mobile phone (Huawei mate40 is used as an example) are as follows: Operating environment: Huawei mate40, HarmonyOS0, and Settings. First, we open the Settings option and click Battery. Step two, we click on wireless reverse charging. The third step, put the device that supports wireless charging on the back of the machine, you can wireless charging.
willAfter the transmission, it is converted into current and transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
3, the principle of wireless charging technology is electromagnetic induction, magnetic field resonance, radio wave and so on. Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.
4, finally realize wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode. High-power wireless charging usually uses resonance (most electric vehicles are charged this way) to transfer energy from the power supply device (charger) to the electrical device. The device uses the received energy to charge the battery and at the same time provide energy for the battery's own operation.
5, wireless charging system mainly uses the principle of electromagnetic induction, energy coupling through the coil to achieve energy transfer. As shown in Figure 1, the input end is when the system worksThe AC mains is converted into direct current through the full bridge rectifier circuit, or 24V DC terminal is used to supply power directly to the system. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Generally, the transmission distance of high-power wireless charging can reach 5 meters at about 0.9-2 meters. Wireless charging technology can be divided into two kinds of low-power wireless charging and high-power wireless chargingStyle. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
The distance is greater than 10 cm, and the conversion efficiency is only about 60%, that is, the sent power is 1000W, and the received power is only 600W.
Currently known reports, the farthest distance is 10 meters, using electromagnetic wave technology. The existing wireless charging technology uses magnetic field, electromagnetic wave, laser, ultrasonic and other energy transfer media. The 10-meter technology mentioned above, using electromagnetic waves as the medium, now stays inThe laboratory stage. At present, the commercial technology on the market is mainly magnetic field as the medium, which is divided into magnetic induction and magnetic resonance 2 technologies.
The distance of the wireless charger can only be effective within the coil range of the charger, more than the distance can not receive charging, each manufacturer's product is different, can not be universal.
Wireless charging distance mobile phone and charger can not leave more than 10cm, the closer the effect is better. Wireless charging technology has always been only related to "small" mobile devices such as smartphones and small-size tablets. However, one of the three major wireless charging camps, A4WP (" Wireless charging Alliance "), has recently announcedThe technical standard has been upgraded, and the charging power supported has been increased to 50 watts, which means that high-power devices such as laptops and tablets can also achieve wireless charging.
On October 17, at the Zhenjiang high-speed Railway Station North Square bus station, the special call intelligent flexible charging bow was officially launched. As the first landing bow type high-power charging equipment in Jiangsu, 13 cities in JiangsuCity bus business leaders together to witness this historic moment. Intelligent flexible charging bow, is a special call for electric bus scene, to solve high-power fast charging unmanned intelligent products.
The use of high-power fast charging can effectively shorten the charging time of new energy vehicles, and the same is true for new energy buses. At present, all cities are equipped with new energy bus fast charging stations. Last year, when I was on a business trip in Shanghai, I saw a bow "charging pile" at the bus station, which should be a special smart flexible charging bow that can complete the charging in less than 1 minute when the bus stops at the stationAlways high.
One-step intelligent electric sharing car, sharing service mode has Geely Zhi Du two cities micro drive, endurance of more than 180 kilometers; IEV6 four types of intelligent electric sharing car, endurance of more than 251 kilometers; The Aishang EV has four smart electric sharing vehicles with a range of more than 200 kilometers. Charging lasts for 10 km for 40 seconds, greatly improving charging efficiency and smooth operation.
Fast charge slow charge this need not be said, in Shanghai Bund if you look, we bus driverless in the last year has invested in the construction of artificial intelligence charging bow, mainly for the future bus driverless, we chargeStation and bus station "two stops in one", when the bus comes, I use artificial intelligence technology to position the bus in this way, quickly drop the bow when people get off, at this time to detect its pressure, and fast charging of large current.
