1, it is achieved by using the principle of electromagnetic induction. The principle of in-vehicle wireless charging technology is achieved by using the principle of electromagnetic induction. Specifically, the wireless charger has a coil inside, and when this coil is connected to the power supply, it generates a magnetic field. The mobile phone or device placed above the wireless charger also has a coil inside, and when this coil is close to the coil of the wireless charger, it will sense a magnetic field, resulting in an electric currentWireless charging now. 2, the breakthrough of vehicle wireless power transmission technology is to find a way to "grasp" electromagnetic waves, that is, to use the "resonance" principle of physics - two objects with the same vibration frequency can efficiently transmit energy. The system consists of the main circuit located outside the car and the secondary circuit, rectifier and drive system located inside the car.
3, the use of electromagnetic induction principle for charging equipment, the principle is similar to the transformer, through the transmitter and the receiving end set coils, the transmitter coil under the action of power to send electromagnetic signals, the receiving end coil to receive electromagnetic lettersAnd convert the electromagnetic signal into current, so as to achieve the purpose of wireless charging.
4, the working principle of wireless charging has four main types: electromagnetic induction charging, magnetic resonance transmission charging, radio wave charging and electric field coupling charging. Electromagnetic induction charging is the most widely used, simple circuit structure, low cost, but the transmission distance is short. Magnetic resonance transmission charge transmission distance is long, but the efficiency is low, it is difficult to popularize. Radio wave charging is more mature, only need to install the transmitter and receiver, convenient and fast.
5, whether the wireless charger damages the phone, we need to understand this beforeBuy your own wireless charging device and keep it in a convenient location.
2, car air purifier useful. one. Can settle particles in the air, can effectively settle dust in the air. Dust, smoke, fiber impurities and other suspended particles can be inhaled to avoid the human body breathing into these harmful floating dust particles: 2. Removing microorganisms and pollutants from the air can effectively kill and destroy the air. Bacteria on surfaces. Mold, while removing dandruff from the air.
3, car air purifier: for areas with poor air quality, car air purifier can help purifyThe air in the car keeps you breathing healthy while driving. Car Bluetooth speaker: High-quality audio that supports Bluetooth connection can allow you to enjoy high-quality music during driving and increase driving pleasure.
4, an electronic receiver, as long as within a certain range of power can be transmitted to the terminal equipment equipped with a receiver, wireless charger using radio waves transmission, radio waves is not only an electromagnetic wave, its own can also transmit energy, and can penetrate the air, This makes wireless power transmission possible for remote start, wireless charging of mobile phones, GPS navigation, car networking, OTA upgrades, BOSEAudio, automatic air conditioning, car air purifier and other configuration.
1, efficiency problem Wireless charging is subject to the development of technology, charging efficiency is still relatively poor, because the wireless charging itself is small power, and the actual performance is not stable.
2, the disadvantages of wireless charger: bound: wireless charging needs to be adsorbed on the charging base, can not be moved at will, the user is more bound than wired charging. High price: The principle of wireless charging is different, resulting in wireless chargersThe cost is usually higher than the wired charger. 3, charging speed may be limited Although many wireless chargers have achieved fast charging, in some cases, their charging speed may still not be as fast as traditional wired charging methods. Especially in the case of low power and the need for fast charging, wireless charging may not meet the needs of users. Higher cost Compared to wired chargers, wireless chargers are usually more expensive.
4, disadvantages: the charging speed is relatively slow. In the era of fast mobile phone charging, wireless charging is very slow. Most wireless chargers now only support 5W charge, slightly faster is only 5W. And wireless charging really can not meet our needs.
5, another major drawback of wireless charging is that it often limits us to a relatively close distance, and sometimes the wireless charger must put the phone in that position, if you move, the phone can not be charged at all. If some friends like to sit and play mobile phones, then wireless charging at this time limits the posture of playing mobile phones, which is very inconvenient.
6, disadvantage 1: the price is high, does not have the popularity of Apple wireless charger price is obviously let a lot of people butOf steps. Although it is not the most expensive among Apple products, the price is much higher than that of many brands of wireless chargers. For ordinary users, this price is obviously unaffordable, so its popularity is not large.
In general, wireless charging and on-board charging box are two effective ways to solve the problem of long-distance charging of pure electric vehicles. Wireless charging is favored for its safety and convenience, while on-board charging boxes provide reliable support in emergency situations. However, for an efficient and fast charging experience, charging piles are still the solution of choice.
If wireless charging technology can be popularized, cars will onlyThe need to stop in the charging parking space can achieve fast charging, which can not only reduce the cost of manual services, but also greatly improve the safety of charging. Secondly, if wireless charging technology wants to be truly popular, it also has high requirements for the precise positioning and intelligence of vehicles. Only when the vehicle is precisely parked in the charging space can the ground system establish a channel with the vehicle's on-board system and achieve charging.
In general, wireless charging technology has certain advantages, such as easy to use, safe and reliable. However, its disadvantages can not be ignored, such as low transmission efficiency, slow charging speed and so on. In the future, withWith the continuous progress of technology, I believe that wireless charging technology will become more mature and more practical.
Therefore, if the wireless charging can be installed on the car, the problem of difficult charging will be alleviated to a certain extent. Wireless charging is mainly based on the Faraday electromagnetic induction principle, which means that the charger and the electrical device are directly connected without wires, but transfer energy through the magnetic field. Wireless charging can be divided into low-power wireless charging and high-power wireless charging two ways, low-power wireless charging often uses electromagnetic induction, such as mobile phone charging.
At present, the wireless charging method of pure electric vehicles is mainly electromagnetic inductionAnd magnetic resonance type. The electromagnetic induction type is mainly used to fix the parking space, while the magnetic resonance type can charge the vehicle while moving. Although wireless charging technology has many advantages, such as improving the charging experience and realizing the wireless discharge of electric vehicles to the power grid, there are still problems such as standards, cost and efficiency, which need to continue to study solutions.
1, the convenience of wireless fast charging has not brought a significant increase in charging speed,Instead, it may be slightly lower than the wired fast charge. The power output of the wireless fast charger to the wireless base is not the final output power of wireless charging, but the input power of the wireless charger. The charging speed of wireless chargers installed on new energy vehicles is limited, which may be due to compatibility issues between external chargers and on-board charging systems.
2, however, in terms of current technological development, the efficiency of wireless charging is lower than that of wired charging. If wireless charging is used, there is no exposed connector when wireless charging of electric vehicles, completely avoiding safety hazards such as leakage and electricity running. And wireless charging can hide power and transformers in the groundUnder, the car can be charged in the parking lot or on the street at a dedicated charging point, so wireless charging is very convenient.
3, in addition to convenient wireless charging disadvantages more than the traditional charging method, the biggest advantage of wireless charging is convenient. When the mobile phone is out of power, it can be charged directly on the wireless charging cover plate, without inserting a cable, which is more convenient. I have a wireless charging module in the car, throw it directly into the car, and it will automatically charge. In addition to the advantages of convenience, wireless charging has many disadvantages.
4, if the charger output is the same, or line charge much faster.
5, different. Moreover, according to different wireless charger manufacturers now, the current and frequency are not the same. (The students themselves bought one online, it is said that the speed is relatively fast. The way to make it is to connect the metal pole of the wireless charger receiving device to the metal sheet of the charging electrode of your own phone, and then drag the wire outside to receive from the outside.) The heat is caused by the large current in the charger, which leads to obvious heat.
Car wireless charging use steps: the carThe wireless charger is fixed in a suitable position in the cab; Connect one end of the USB data cable of the wireless charger to the car cigarette port and the other end to the wireless charger; After fixing the position of the wireless charger, make sure that it is stable and will not slide, put the phone on and charge it. Wireless charging technology comes from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
Buy a wireless charger that matches your phone: After making sure your new device is compatible with your phone model, choose a location that is easy to reach during driving and fix it. Connect the power: USB data cable will not be availableThe wire charger is connected to the cigarette lighter interface of the car to ensure that the charger is stable for stable power supply.
The use of the car wireless charger is as follows: First, it is installed in a suitable position in the car, one end of the data cable is connected to the car cigarette lighter, and the other end is connected to the wireless charger. After making sure that the charger is stable, the phone can be charged by placing it on the charging pad. It should be noted that the phone should support this feature when charging wirelessly. When using the mobile phone bracket wireless charging, the wireless charging module should be used in combination with the mobile phone bracket.
