Toshiba Unveils SCiB 24V Battery Pack for Marine and Industrial Applications

Toshiba Corporation has announced the launch of its SCiB™ 24V battery pack (P25H20-3), a lithium-ion solution targeting automotive, marine, and industrial equipment markets. The product is positioned as a direct replacement for conventional lead-acid batteries.

The battery pack has been deployed in Yamaha Motor's electric boat, "e-Float Terrace," which is set to commence sightseeing cruises in Yokohama's Minato Mirai district in October. The vessel utilizes twenty-four SCiB™ battery packs configured to deliver 48V and 11.52 kWh of power through Yamaha's HARMO electric propulsion system.

Engineered to meet the D23 size specification outlined in Japanese Industrial Standard JIS D 5301 for starter lead-acid batteries, the SCiB™ 24V battery pack facilitates straightforward replacement of existing 24V lead-acid units. The design allows for scalable configurations—up to two units in series and six in parallel—to achieve 48V output and 5.76 kWh capacity.

The battery pack incorporates 20Ah-HP SCiB™ cells and is suitable for high-load operations including engine starting. Target applications include marine vessels, commercial vehicles such as buses and trucks, and heavy equipment in construction and agricultural sectors.

"We engineer SCiB batteries for outstanding reliability in demanding environments," stated Toshihiko Takaoka, Vice President of Toshiba's Battery Division. The battery pack features waterproofing certified to IPX9K and IPX7 standards, alongside low-temperature performance and vibration resistance designed for harsh operating conditions.

The SCiB™ technology offers several operational characteristics: rapid charging capability, extended service life, high input/output power capacity, and a wide usable state-of-charge range. These attributes address market demand for alternatives to lead-acid batteries that provide weight reduction, improved efficiency, and reduced environmental impact.

Yamaha Motor's adoption of the battery pack aligns with the company's initiative to promote sustainable urban tourism through electrification of marine transport and reduction of carbon emissions in the mobility sector.

Toshiba indicated plans to pursue additional orders across marine and industrial applications while continuing to expand its SCiB™ product portfolio for mobility, industrial, and energy storage applications.
