Mass production of wireless charging transmitter modules as fast as wired connections, improving charging speed and compatibility
Widespread adoption of wireless charging in finished products such as vehicles and furniture is expected.

LG Innotek (CEO Park Jong-seok) has commercialized a wireless charging pad that can charge smartphones as quickly as a wired fast charger without a cable.

The company announced on the 12th that it has begun mass production of the world's first 15-watt (W) wireless charging pad. This is the first mass production for consumer sales, not for prototypes.

A wireless charging pad is a device that supplies power to smartphones and is designed in a slim shape resembling a coaster. When a wireless charging smartphone is placed on it, the battery is charged. This 15W wireless charging pad is scheduled to be sold in Europe, North America, Australia, and other regions starting in mid-October through global smartphone accessory manufacturers.

LG Innotek has further upgraded the charging speed and compatibility of the wireless charging pad and enhanced safety by applying an overheat detection function during charging.

This company's 15W wireless charging pad charges three times faster than existing 5W products. It can charge to 50% in just 30 minutes from a completely discharged state. This is because it can supply 15W of power to the smartphone battery, just like a wired fast charger.

Furthermore, this product boasts excellent compatibility, allowing it to be used with most wireless charging smartphones sold to date. It complies with the technical standards of the Wireless Power Consortium (WPC), an international standardization organization for wireless charging.

In addition, this product features an overheating prevention function during charging, which can reduce the risk of smartphone performance degradation and battery explosion. A sensor built into the wireless charging pad measures the temperature of the part in contact with the smartphone and cuts off power supply if it overheats above a certain level.

LG Innotek expects that the mass production of this 15W wireless charging pad will lead to the widespread adoption of wireless charging capabilities in products other than smartphones. This is because the wireless charging module can be used as an embedded unit by optimizing its design to fit finished products such as automobiles and furniture.

According to market research firm Techno Systems Research (TSR), the global wireless charging transceiver module market (based on revenue) is expected to grow from $553 million last year to $2.017 billion in 2019.

Heo Seong, Executive Director of the Electronic Components Business, stated, “We have proven our world-class wireless charging technology,” adding, “As wireless charging modules are components directly related to user convenience and safety, we will meet customer expectations with superior performance and impeccable quality.”
