GS Yuasa EHW4GA Lithium-Ion Battery Adopted for Overseas Lexus ES Hybrid Models

GS Yuasa Corporation announced on August 4 that its EHW4GA automotive lithium-ion battery has been selected for hybrid versions of the LEXUS ES sold in overseas markets. The milestone represents the first time an automotive lithium-ion battery developed by GS Yuasa has been installed in a Lexus vehicle. The latest adoption further expands the company's presence in hybrid vehicle battery applications while supporting improved efficiency and performance for electrified passenger vehicles.

EHW4GA Battery Brings Higher Energy Density for Hybrid Models

The EHW4GA battery cells and modules are manufactured and marketed by Blue Energy Co., Ltd., a company within the GS Yuasa Group. The same battery technology is also used in the latest RAV4. Although the new cells maintain dimensions and weight comparable to Blue Energy's existing mass-production products, they deliver an increase in energy density exceeding 10%. The enhanced design enables improved overall battery performance without increasing package size or mass.

Advanced Technology Improves Hybrid System Performance

According to the company, advanced low-resistance technology has increased the input and output characteristics required for hybrid systems by more than 10%. In addition, the battery modules utilize a die-cast case that lowers both component count and overall weight. These improvements contribute to enhanced efficiency, simplified module construction, and better performance for hybrid vehicle applications while maintaining compatibility with existing packaging requirements.
