Seiko Epson Corporation and Murata Manufacturing Co., Ltd. have agreed to jointly develop a wireless quick battery charger capable of a substantially shorter charging time.

Prototypes of this product are scheduled to be exhibited at Murata Manufacturing's booth at CEATAC JAPAN 2007 (on October 2nd to 6th at Makuhari Messe) and at Epson's booth at Embedded Technology 2007 (from November 14th to 16th at Pacifico Yokohama).

Background and purpose

Mobile devices, such as mobile phones, portable audio players, and notebook PCs have become extensively widespread and their growing sophistication has caused them to consume greater quantities of electric power. As a result, developing ways to increase the length of time such devices can be operated after each charging has become a critical issue. Moreover, it is anticipated that the frequency with which charging must be done will increase in the future.

The thin, compact wireless quick battery charger system being jointly developed by Epson and Murata Manufacturing will be a revolutionary product that will shorten the charging time from the one to two hours required by currently existing charging systems down to approximately ten to fifteen minutes. Furthermore, a wireless charger makes it possible for devices that would ordinarily require their own dedicated charging units to share a single charging unit. In the future, when batteries will need to be charged more frequently, this system has the potential to greatly improve the ease and convenience of charging batteries.

Murata Manufacturing has a wealth of experience with compact, thin modules, and with power supply circuits. In addition, it has been working on developing a lithium-ion secondary battery, which it is pursuing as a new business. A lithium-ion secondary battery is capable of the quick charging of a large amount of electrical energy.

Epson has long been engaged in developing a non-contact, high-efficiency power transmission system and possesses certification system and IC technologies. The two companies have agreed to carry out joint development, with the goal of producing a commercially viable product within three years.
