Wireless charging technology will certainly become standard over timeThe reason why wireless charging technology has not been used on mobile phones before is actually because the power of wireless charging is still not enough. For example, the previous 5 watts of wireless charging ah, to the last 5 watts of power is relatively low, I do not know wireless charging and wired charging is different, although the standard wattage is relatively high, but it will be greatly discounted when it is really used.
The first is the charging efficiency, the current wired fast charge can achieve 30W-40W power, and even 55W ultra-high fast charge technology is under development, in contrast, wireless charging is limited by existing technology, the power is generally small, Apple is currentlyOnly 5W, wireless charging speed can not keep up with mainstream demand; The second is the price, the price of wireless charging is generally higher than that of wired charging.
At present, it is not hot, and only high-end mobile phones are equipped with wireless charging function, which can be imagined that the cost is not low. For now, the application of low-end machines is obviously not yet ripe. Wireless charging technology does not use charging lines at all, but uses magnetic fields to charge devices, and is inspired by wireless power transmission technology.
May wireless charging this function sounds like a very powerful function, after all, wireless must be the trend in the futureIs it different '> Is overcharge different from other charging?
1. There is indeed a significant difference between supercharge and other charging methods. In the field of electric vehicle charging wireless supercharge technology , supercharge usually refers to the wireless supercharge technology is a fast charging technology wireless supercharge technology , This technology can replenish the battery of an electric vehicle with a large amount of charge in a very short period of time. In contrast toOrdinary charging methods often take longer to complete the same power supply. Overcharge technology uses higher charging power.
2, the gap between the two is not as large as some users think. As long as the charge will inevitably have a loss, the impact of the battery is not only fast charge, such as current, voltage, etc., may cause harm to the battery, the current and the battery need to match, which involves the problem of charging the equipment used.
3, charging speed: In general, "super fast charge" usually provides faster charging speed than "Turbo charge". This is because of superStage fast charge technology usually uses higher power charging devices, which can charge more power to the battery in a short time. For example, Huawei's Super Fast Charge technology can charge a battery to 70 percent in 30 minutes, while Turbo charging can take much longer to reach the same level of charging.
4, so whether it is overcharge or electricity, it is bound to have advantages and disadvantages, standing in the consumer's point of view, the extra cost is not the same. So from another perspective, this is actually a choice of money and time. Fast charge and overcharge, charging and power change, are generally the same. Money and timeIn fact, it does not belong to the same dimension, let alone two sides of the coin, and there is no absolute opposition.
3, so if wireless chargingThe way does not change, this type of user is difficult to increase, not to mention the fire is not popular. 4, compared with wired charging, wireless charging this way does not seem to be dominant, and the current technical shortcomings, such as low charging efficiency, standard is not uniform cost is high, these are almost the fatal injury on the road to its popularity.
5, the two main camps, the Wireless Charging Alliance (A4WP) and PMA, have declared mutual compatibility, which means that future wireless charging devices based on these two standards will be able to be compatible with each other's phones, greatly expanding the scope of equipment adaptation. However, about how to achieve twoThe bidirectional compatibility of the standard is not yet detailed. Broadcom chief technology officer Henry-Samueli pointed out that the biggest obstacle to the adoption of wireless charging technology is the inconsistent standards.
6, this is also an important reason for the current wireless charging technology has not been popularized, at present can only say that this thing can be achieved, but mass production still needs time. As long as the wireless charging technology can be more mature in the future, making the charging efficiency become faster, and can achieve the charging function of running while charging, then I believe that wireless charging technology will definitely become the preferred configuration technology of new energy vehicles in the future.
1, Tesla acquired the German WIFERION, in the modified version of the Model 3 application of wireless charging technology, behind the logic is electromagnetic induction wireless charging. At present, the modified Tesla Model 3 can achieve a maximum of 12KW wireless charging power, the fastest one hour to make up 80 kilometers, full may take about 6 hours.
2. First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. The technology transmits energy through special electromagnetic fields, allowing Tesla cars to charge themselves when parked. This technology is not only efficient, but can also greatly reduce charging time. Secondly, the wireless charging technology of Tesla cars also has the characteristics of intelligence. 3, the charging process of Tesla takes about 12 hours, but when using a home charger, the voltage may drop due to the peak of the transformer load, which affects the charging speed. In order to improve efficiency, it is recommended to install a special wall-mounted charger, so that when chargingTime will be reduced to approximately nine hours. The optional dual built-in charger can further shorten the charging cycle, and it only takes about 4 hours to full charge.
4, for example, the commonly used charging pile fast charging power is generally more than 60kw, the minimum slow charging power is also more than 7kw, so the current electric vehicle wireless charging still looks very good, but the practical value is not high. In fact, compared with the fixed wireless charging technology, the charging technology of the car on the road is the most worthy of expectation.
5, Zhiji Automobile announced on March 15, its first 11kW high-power vehicle intelligent wireless charging scheme landed, and its chargingThe efficiency is close to the wired charging (reaching about 95% of the same power wired charging efficiency), and has the function of collaborative position detection. The wireless charging board has a protection grade of IP6IP6K9K, and adopts a high-strength design to support metal and live foreign body detection.
6. Specifically, Wanan Technology participated in Evatran, a leading wireless charging enterprise in the United States and a wireless charging supplier of Tesla, to obtain core wireless charging technology; Shuobed magnetic resonance wireless charging technology is the focus of the company's research and development direction, has obtained magnetic resonance wireless charging system utility model patent.
Slightly slower charging speed: Compared with wired charging treasure, even if it has fast charging, the charging speed of wireless charging treasure will be slightly slower, especially for devices with large-capacity batteries, and the charging time is longer. Compatibility limitations: Wireless charging bank requires devices to support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience.
Each has its own advantages: wireless charging is convenient, no need to connect handsMachine on the charger, put on the charging board; Wired charging is more stable, and the charging speed is faster than wireless charging.
The second kind of wireless charging, its working principle is the most used electromagnetic induction, wireless charging less line bondage, each charge on the go, compared with wired charging, it does not plug and unplug the data cable cumbersome, so charging is more safe, more fast, its disadvantage is that the charge is relatively slow.
