[Asia Economy Reporter Jeong Hyunjin] Doosan Infracore announced on the 10th that it has completed the production of the first prototype of its self-developed battery pack.

A battery pack is the final form of a battery system installed in electrified equipment. It consists of battery modules, which bundle a certain number of battery cells into a frame, along with various control and protection systems such as the Battery Management System (BMS) and cooling system.

Doosan Infracore's battery pack is designed by combining standardized cylindrical battery cells to match unit voltage and capacity. The Battery Management System also applies standardized and shared design, allowing the battery pack to be configured with up to 32 modules regardless of series or parallel connections. Doosan Infracore explained that structural adhesive is used physically when connecting battery cells, and wire bonding technology is applied electrically.

Doosan Infracore has been promoting in-house development of battery packs after reviewing the feasibility of the electrified powerpack business last year. With this prototype, actual equipment mounting tests will be conducted, and by early next year, the first product of a 1.7-ton electric excavator equipped with the battery pack is planned to be produced. A Doosan Infracore official said, "Battery packs can be installed on all equipment that can operate electrically, including construction machinery, agricultural machinery, and golf carts," adding, "The battery pack business aims for annual sales exceeding 500 billion KRW by 2030."

Previously, Doosan Infracore developed 'mild hybrid powertrain' technology, which is an intermediate stage between internal combustion engines and electrification. The hybrid powertrain combines an internal combustion engine with an electric motor and battery, providing strong starting performance along with improved fuel efficiency, enhanced output, and reduced carbon emissions, Doosan Infracore explained.

Son Dong-yeon, President of Doosan Infracore, emphasized, "As Korea's top engine specialist company, we have developed various engines for vehicles, ships, industrial use, and defense, and export them to Germany, the home of engines, as well as Europe, China, and other regions," adding, "Amid the major paradigm shift in internal combustion engines, we will accelerate the development of hybrid powertrain and electrification technologies to establish ourselves as a global leader in the engine market."
