1, electric vehicle wireless charging technology has become a hot electric vehicle to become the mainstreamThe problem of battery life has not stopped, in order to solve the battery life problem, the various car companies are also trying their best to find a way to solve this problem, in addition to changing electricity and fast charging, in fact, there is a different way, that is, road charging, so that the car on the road running while rushing.
2, Tesla acquired the German WIFERION, in the modified version of the Model 3 applied wireless charging technology, the logic behind is electromagnetic induction wireless charging. At present, the modified Tesla Model 3 can achieve a maximum of 12KW wireless charging power, the fastest oneReplenished at 80 kilometers per hour. Full charge could take about six hours.
3, wireless charging process will definitely heat. As long as the temperature is not very high, no problem, you see if there is something around the block, because many times love to put some things on it. 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.
4, for electric vehicles with wireless charging, mostly through the power supply coil arranged on the ground and the electric coil at the bottom of the vehicle, through the magnetic resonance generated between the coils to replace the traditional power lines for the carThe output VBUS switch tube is in the package of VS3618BE, NMOS, 30V, PDFN3333.
BE is a VBUS switch tube, the complete model is VS3618BE, using PDNF3333 package, logic voltage drive, used as a VBUS switch in Xiaomi's original 30W fast charger.
1, the firstFeatures: The screen completely cancels the camera, there are certain technical difficulties. Take the Mi MiX 4 as an example, which is a domestic full-screen phone. The fatal disadvantage is that the front blur is not suitable for photographers. Xiaomi 13 Pro in order to ensure the photo effect, decided to take a hole screen. A circular camera hole appeared on the screen, trying to increase the proportion of the screen.
2, millet 13Pro engineering real machine has any bright point? The biggest highlight of this model is the Samsung E6 high frequency PWM dimming screen, but also a large CMOS main camera, the new latent ultra-telephoto, 500 mah battery hundred watt fast charge. This mobile phoneIts operating memory is 12GB plus 3GB of extended memory. The screen is 36 inches and uses four equally wide bezels, all of which are ultra-narrow in design. This version of the model uses the latest A16 bionic chip. 3, in the screen part, Mi 13 adopts customized high-end OLED straight screen, the four sides are equal width, the narrowest point is only 61mm, and the widescreen ratio is as high as 93%, which brings users the ultimate visual enjoyment. The battery capacity is 4500mAh, which is said to be the strongest in the history of Xiaomi's flagship machine, meeting the needs of daily use.
4, millet 13 will be pickedWith a large main color of 50 million pixels, coupled with a high-pixel telephoto scheme, in any case, the material of Mi 13 is always full of sincerity, as for the specific experience, but also wait for the feedback of the market, no matter how much you like a brand, there is no need for firm support, after all, accidents always accompany life.
5, conclusion: The real design of the Mi 13 Pro is impressive, and the appearance is rich in exposure details, especially its hyperboloid central perforated screen and huge square camera module, indicating a new visual experience. In the photos shared by a blogger of science and technology University, the machine has been running pre-installed MIUI 14 system, is expected at tomorrow night's conference, millet 13 series will be fully upgraded to Snapdragon 8 Gen2 processor, memory and flash memory configuration will also be improved.
1, Millet 55W vertical air-cooled wireless charging using PC flame retardant material plastic shell, fuselage edge clear end corner arc transition, support board is black, base sandblasting treatment is gold. From the front, bottomThe front end of the seat is equipped with LED indicators, and the support board is layered up and down, using different designs. Indicator light is green when working.
2, compared with the common 10W wireless charging technology on the market, Xiaomi's 30W wireless flash charge can charge half of the 4000mAh battery in 25 minutes, achieving the efficiency of "wireless beyond wired". Xiaomi's vertical air-cooled wireless charge 30W is cleverly designed with an ergonomic tilt, which is convenient for users to operate while charging, and the built-in ultra-quiet fan can effectively actively dissipate heat, improving the comfort of the charging process.
3, millet verticalAir-cooled wireless charger (55W black) 199 yuan currently millet maximum power (charging speed is the fastest) wireless charger, if the phone is 30W or 33W wireless charging power, then it is recommended that you "redundant" to buy this power of the wireless charger, because the mobile phone upgrade faster, The wireless charger this product can be used for several years, and the new mobile phone can also achieve power coverage in the future.
1, AP45851 compatible with high power output, chip compatible with Qi fast charge protocol (5/9/12V application), in line with the latest Wireless charging Alliance (WPC) Qi version specifications. The AP45851 uses the unique CNS-chip as System technology to fully integrate a variety of high-performance mixed-signal functions, such as low-power device detection during standby and foreign object detection (FOD) for secure wireless charging.
2, play the role of metal isolation, prevent energy wavesFee, improve charging efficiency.
3, wireless charger refers to the use of electromagnetic wave induction principle for charging equipment, the principle is similar to a transformer. There is a coil in the sending end and the receiving end. The sending end coil is connected to the wired power supply to generate an electromagnetic signal, and the receiving end coil senses the electromagnetic signal of the sending end to generate a current to charge the battery.
4, wireless charging technology is the use of electromagnetic induction principle, in the sending and receiving end with the corresponding coil to send and receive inductive current to charge.
2, ** Original charger and cable confirmation ** : First of all, please confirm whether you are using the original charger and data cable of millet. Charging devices that are not original or third-party brands may not be availableHold Xiaomi's fast charge agreement. ** Integrity check of charging equipment ** : Check whether the charger and data cable are damaged or in poor contact, such as loose plug, cable breakage, etc. These problems can cause the charging speed to slow down or not be fast.
3, choose the right charging mode: Some mobile phones provide different charging modes in the Settings, such as "fast charging" and "standard charging". You can find and select the appropriate mode in your phone's Settings menu. For example, on a Samsung phone, you can go to "Settings" - "Device maintenance" - "Battery" - "MoreBattery Settings "to select the charging speed.
4, the charging speed can not be changed, the mobile phone charger voltage 3v current 500ma-1A, if you need 9v DC, buy a multimeter with the battery on the line, 9v, or from the repair of electric vehicles to buy a bad own modification, if not ask me again.
5, the charging line does not match may change a charging line, charging will be slow. The charging temperature is too high. If the charging temperature is too high, the battery temperature will be higher than a certain value. As a result, the charging current will gradually decrease, and the charging speed will slow down, resulting in a decrease in the charging speed. The data cable interface is not plugged properly. The data cable interface cannot be fully plugged into the phone, so that the fast charging may enter the ordinary charging mode, resulting in the problem of slow charging.
