GS Yuasa Corporation (Tokyo Stock Exchange: 6674; “GS Yuasa”) announces that its automotive lithium-ion battery “EHW4GA” has been adopted for the hybrid models of Toyota Motor Corporation’s LEXUS ES for overseas markets.

The cells and modules for "EHW4GA" are manufactured and sold by Blue Energy Co., Ltd. (“Blue Energy”), a GS Yuasa Group company, and they are also used in the new RAV4. While maintaining dimensions and mass comparable to Blue Energy's mass-produced products, the cells achieve more than a 10% increase in energy density.
Furthermore, by developing advanced low-resistance technology, the input/output characteristics required for hybrid systems have been improved by more than 10%, thereby optimizing overall battery performance. In addition, for the modules, the adoption of a die-cast case has resulted in a reduction in the number of parts and weight.

GS Yuasa established Blue Energy in 2009 as a joint venture for the development, manufacturing, and sales of high-performance lithium-ion batteries for hybrid vehicles. To date, Blue Energy has stably supplied batteries for over 4.15 million hybrid vehicles. With this extensive track record and advanced technological capabilities, GS Yuasa will continue to contribute to the widespread adoption of environmentally friendly vehicles.
