Wireless charging has entered the 2.0 era. The first generation introduced consumers and enterprises into the world of wireless charging with magnetic induction technology. The next generation of resonance and radio frequency technology will give full play to the full potential of wireless charging.Especially in 2019, the demand for medium and high power wireless charging (WPT) for new applications such as 5G, laptops, robots, mechanical tools and medical devices is increasing, and the next killer application of wireless power will be born in the next five years.
On March 12, in shenzhen shekou Hilton Hotel held AirFuel wireless charging alliance meeting, AirFuel wireless charging alliance chairman Sanjay Gupta full of confidence to participate in the meeting of more than 200 Chinese and foreign power engineers said.
The advantages of resonance and radio frequency are obvious: more freedom in space, faster charging, cheaper and easier to install infrastructure.2019 will be a significant year for the industry as we move from first-generation induction technology to second-generation resonant and rf solutions. Through this transformation, wireless charging will be able to meet the growing demand and take us one step closer to a world without charging lines.
Sanjay Gupta points out that many people like wireless charging and the market for wireless charging is growing.In 2018, 500 million devices adopted wireless charging, an increase of 40% compared with 2017. By 2022, the wireless charging market will have 2 billion receivers and senders, and the wireless charging market will reach 12 billion usd.
"A mobile phone covers more than 20 communication protocol, bluetooth, baseband, WIFI and NFC communication and so on, also, A protocol can't meet the demand of different power, A device to support multiple protocols to meet the demand for electricity and AirFuel USES two kinds of mature technologies: AirFuel rf technology, magnetic resonance and magnetic resonance AirFuel in 6.78 MHz operation, in this frequency magnetic resonance to realize power transmission, power transmission from A to B; rf technology for power transmission is close to 900 MHz."AirFuel provides a communication protocol that covers both resonance and rf technologies," says Sanjay Gupta.High efficiency, communication, meet the needs of different customers.AirFuel provides interoperability testing and certification to ensure that the product is interoperable and safe as it enters the market."
Future vendors move from the Qi standard to the AirFuel standard.Initially, the scenarios covered by wireless charging were smart phones, wearable watches, and electric toothbrushes. Today, we will see high-power AirFuel wireless charging solutions that are compatible with high-power devices such as robots, drones, and industrial devices.In particular, it can realize wireless charging of robots and tablet computer devices.
JjPLUS, a business partner of EPC, told reporters that AirFuel wireless charging alliance resonance technology provides the best application scenario for the automatic robot.These robots adopt the embedded wireless charging technology, based on the AirFuel standard, and have more space degrees of freedom, so that the robot does not need to stop at a certain position for charging.In contrast, the robot only needs to approach the AirFuel resonance charging area, and the wireless power transmission will automatically start and cycle charging.GaN is the best choice for high-power devices in the selection of materials using magnetic resonance technology. Paul Wiener, the head of GaN Systems, said that the total efficiency of the system can be improved to over 80% by using GaN field-effect transistors and integrated circuits.The 2-by-3-foot desktop on display enables wireless charging to power multiple devices simultaneously.
In particular, Sanjay Gupta points to interoperability and scalability as the foundation for the rapid expansion of the wireless charging market.Different vendors offer different electronics to consumers, and ensuring that different devices use one technology to charge is key to improving the customer experience.Scalability is especially critical. Charging devices vary from device to device, and there has to be a common technology to scale. People don't want to choose between wireless or fast charging.If it takes only 30 minutes for a mobile phone to charge up to 80%, and it takes two hours to charge up wirelessly, people will inevitably choose devices with higher charging efficiency.The needs of customers have been very clear, they need wireless charging, and it is fast charging, the whole charging process is safe.This is the advantage of AirFuel technology.
Figure: the charging board using AirFuel magnetic resonance technology can be used for wireless charging of multiple electronic devices, which can support up to 8 devices.
At present, many electronic products are charged through inductive technology, requiring direct contact between the device and the power source, such as precise alignment between the phone and the charger.If the user wants to use the device during charging, he must stay in a fixed place and cannot charge multiple devices at the same time.In the era of wireless charging 2.0, the second-generation wireless charging technologies such as resonant and rf can realize long-distance charging across wooden tables or marble, and can charge multiple devices of different models and sizes at different speeds at the same time, providing a better user experience.
In the 5G market, AirFuel standard charging technology is also quite promising.In the 5G terminal market, the launch of 5G CPE has two functions. First, 5G signals are converted into WIFI signals. At the same time, 5G CPE can be used as a repeater of wireless signals to expand the network range or relay Internet access.In some places, there is no 4G or 5G signal. CPE can be used for signal relay to expand the base station signal coverage, which is very important for the initial 5G experience.For wireless charging 5 g CPE, the Taiwanese company, the leader of the orange said AirFuel resonance technology for wireless charging union 5 g CPE charge to provide the best application scenario, we provide wireless charging device in 20 w to 65 w, wall 20 cm to 30 cm, we provide the power supply outdoor, also can convert to come in, this is a huge market potential.
