When the advertisement of Samsung S6 wireless charging function comes over, the automobile industry is about to usher in the era of wireless charging. On May 23, local time, German Daimler Group and Qualcomm announced a new strategic cooperation agreement to jointly develop wireless charging technology for electric vehicles and wireless charging technology for on-board mobile devices.

　 ■ Join IT

It is reported that Daimler will collaborate with Qualcomm Technologies, a subsidiary of Qualcomm, and use their respective resources to jointly develop a variety of new technologies. The two sides will work on the research and development of wireless charging technology for pure electric vehicles and plug-in hybrid vehicles to reduce dependence on charging piles and promote the marketization of pure electric vehicles and plug-in hybrid vehicles. In addition, the two parties will jointly develop wireless charging technology for mobile devices on the vehicle, allowing users to charge mobile devices such as mobile phones when driving a car to ensure the endurance performance of these devices, while allowing users to enjoy 3G/4G network services and improve onboard connectivity. Experience.

Currently, Daimler and Qualcomm Technology are collaborating on the “High-Performance Wireless Power Transmission 2.0 Project” for electric vehicles. Through Qualcomm Halo's wireless charging technology (WEVC), it provides a high-performance, high-power compact car kit that allows Mercedes-Benz consumers to wirelessly charge their pure electric vehicles and plug-in hybrids. In addition, Qualcomm's WiPower wireless charging solution allows consumers to charge electronic devices in the car. “It is very important to stand on the forefront of technology and continue to provide consumers with an unparalleled experience,” said Thomas Weber, a member of the board of directors of Daimler who is responsible for research and development. “It is based on this concept that we are eager to become an international leader in technology such as Qualcomm. The company explores possible future cooperation areas."

The two parties stated in the joint statement that Qualcomm hopes to help the automotive industry create a new experience integrating exchange, convenience, energy saving, infotainment and security. Daimler is producing models that reflect these elements. Daimler and Qualcomm hope to pass The collection of both sides' automotive expertise will provide intelligent vehicle networking for future zero-emission vehicles and promote the development of the industry. "We have always sponsored the Mercedes AMG team. This cooperation with Daimler is a natural extension." Derek Abberley, chairman of Qualcomm, said, "We are constantly using our expertise in wireless charging. Knowledge, to provide consumers with an easy and convenient driving experience.”

　　 ■ Public car companies frequently feel presence

Qualcomm is not Daimler's only partner in the field of wireless charging. Last July, BMW announced that it had signed a cooperation agreement with Daimler to jointly develop a new generation of wireless inductive charging technology for pure electric vehicles and plug-in hybrid vehicles. BMW said that the technology could be used for its i-series electric vehicles in the future, and charging will become more effective, safe and convenient. The wireless charging system developed by BMW and Daimler consists of two parts: an auxiliary coil mounted on the chassis of the vehicle and a main coil installed on the ground. The main coil transfers electric energy to the auxiliary coil through a magnetic field change, and the charging power is 3.6 kilowatts per hour. Enough to fully charge plug-in hybrid vehicles within three hours. BMW put the commissioning of the wireless charging system as a mid-term goal, so it could not be seen in real life in a short time.

In addition, Volkswagen, Toyota, Volvo, Tesla, Nissan and other car companies also have a sense of presence in the wireless charging area. At the just-concluded 2015 CES Asia Consumer Electronics Show, Volkswagen released the concept of the Volkswagen Golf Connect, and said that the car is equipped with new technologies such as wireless charging and remote control. However, the masses did not immediately apply wireless charging technology to mass-produced vehicles because the wireless charging technology still faces some difficulties. Wireless charging standards are not yet uniform and the cost is high. It is too expensive for families with two electric cars and it is inconvenient for those who use public parking. As Volkswagen's engineer Herbert Routall puts it: “The standard is not uniform and it is not good for customers. If your family or company has different cars, you should not want to buy one for each car. Wireless charging system.” Therefore, VW expects to use the wireless charging device as an option for its electric vehicles around 2017.

The customer's needs will further determine when and to what extent the public will provide wireless charging technology. The competitors' strategies will also affect the public's timetable. For example, in February last year, Toyota announced the development of a wireless charging system and began a one-year test using several Prius plug-in hybrid vehicles in Aichi Prefecture, Japan. Volvo’s vision is even more bold. It proposes and tests the “Electrified Road System”, which is laying cables in the roads and allowing continuous charging when electric vehicles pass through. Tesla is also developing wireless charging technology that can be connected to its models.

　 ■ began to spread in 2017

On May 29, local time, IHS, a US consulting company, released a report on the prediction of the popularity of automotive wireless charging systems. The report pointed out that by 2020, the number of cars that provide wireless charging devices for mobile devices such as smart phones in the car will soar to 17.5 million, and the wireless charging methods for electric vehicles will become popular after 2017. Anthony Thomson, vice president of business development and marketing at Qualcomm, also said that wireless charging technology is expected to be used in production cars by 2017.

In fact, in South Korea, wireless charging of electric vehicles has entered the lives of ordinary people. In 2013, a 12-kilometer wireless charging section was laid in Gumi City, South Korea. A pure electric bus was running on the road to charge while driving. This road was laid by Professor Dong-HoCho of the Korea Institute of Science and Technology (KAIST), and later this car wireless charging test project named “OLEV” was applied to more buses to verify the indicators of this technology. .
