Car wireless charging

According to IHS, wireless inductive charging for mobile devices has become a trend that has existed on the market for several years. With this new technology, you don't have to plug your phone into a cigarette lighter, a 12V charger, or a USB port, and users can wirelessly charge the battery.

However, many vendors have tried to provide solutions. In most cases, the systems cannot use each other. However, all this may be changing now.

GM invests in Powermat

In January of this year, the United States General Motors (CM) and Powermat announced a $5 million investment plan funded by General Motors subsidiary GMVentures. This investment may enable Powermat's induction charging to enter many future Chevrolet, Buick, GMC and Cadillac models as quickly as mid-2012.

Powermat's technology allows electronic devices such as smartphones, MP3 players and game consoles to be charged without plugging in; Powermat has begun selling wireless chargers for personal use. In most cases, when charging a smartphone, a housing with a small receiver must be attached to the phone. The receiver allows the mobile phone to communicate with the powermat and charge the battery via induction without wires.

Although General Motors stated in the statement that the Chevrolet Volt will be one of the first cars to adopt the above technologies, a larger number of cars may bring about a real revolution in car charging methods.

Volkswagen and Audi take action Audi had ideas for wireless charging at the 2010 SEMA show, and presented a product with Qualcomm and Peiker to wirelessly charge smartphones, PDAs and other devices. Audi will market this wireless charging solution as an accessory.

At the same time, Volkswagen’s Electronic Research Laboratory in Silicon Valley, USA, is working on a car center console that can wirelessly charge smart phones, similar to the home-oriented powermat marketed above. This project, carried out in collaboration with Qualcomm, is said to have the potential to use magnetic near-field resonance to drive rear seat entertainment or ambient lighting systems. This made Audi's concept shown six months ago a bit closer to production.

Chinese OEMs and their role at the recent Shanghai auto show can see an interesting trend, that is, Chinese OEMs are working hard to wirelessly charge mobile devices in the car. Some Chinese OEMs are trying to be at the forefront of the new competition for mobile wireless charging, including the introduction of mobile wireless chargers into cars.

The EmgrandEC8 is Geely's flagship model and has a mobile wireless charging system at the bottom of the central control panel. According to Geely, wireless charging is ready for mass production, but the launch date has not yet been determined.

Chang'an Automobile also exhibited a sample of a future car, featuring several advanced driver assistance systems (ADAS), and a wireless charging system for mobile devices in the rear central armrest. According to Changan Automobile employees, this wireless charging standard is called “Qi” and was developed by the Wireless Charging Alliance (WPC). Since August 2010, it has been promoted as an industry standard in Beijing. Many Chinese companies have launched their own Qi wireless charging standard products, and Chinese OEMs seem to be eager to bring the technology to market.

Will OEM make a commitment?

The biggest factor driving wireless charging in the car is the attitude of the consumer electronics industry to the technology. The ultimate goal is to integrate the inductive charging chip into the smartphone or the battery itself to ensure compatibility while avoiding the additional cost of using the housing.

IHS believes that by cooperating with the consumer electronics industry and adopting the universal Qi standard, Chinese OEMs may actually introduce the technology into cars faster than foreign peers. However, if their efforts in this area deviate from expectations, these OEMs may find it difficult to obtain a return on investment.

As the connectivity and ease of operation of mobile devices in the car are becoming hot topics for OEMs, placing the mobile device on the nearby charging board for wireless charging will sound good to the driver. However, it remains to be seen whether this kind of creativity can bring profits to OEMs.
