SEOUL, May 10 (Yonhap) — Construction equipment maker Doosan Infracore said Monday that it has rolled out a prototype of battery packs for construction equipment and agriculture machinery.

The battery packs comprised of battery modules, battery management systems and cooling systems will enable Doosan Infracore to release 1.7-ton electric excavators by early next year, the company said.

Doosan Infracore said it aims to post 500 billion won (US$448 million) in sales of its battery packs in 2030.

The battery packs could be mounted on construction equipment, agriculture machinery and golf carts, the company added.
