Doosan Infracore has announced that it has manufactured its first prototype battery pack developed in-house.
The prototype is expected to help Doosan Infracore accelerate its battery pack business and motorised product development.
“A battery pack is the final form of the battery system mounted on motorised machines,” explained Doosan Infracore. “It is configured with control and protection systems, such as a battery module that bundles a certain number of batteries in cell units into a frame, a battery management system (BMS) and a cooling system.”
Doosan Infracore’s battery pack offers a flexible design to meet unit voltage and capacity requirements by combining standardised cylindrical battery cells.
Using the BMS, the standardised and shared design has been applied to enable battery pack configuration with up to 32 modules regardless of parallel or serial connection.
The battery cell offers improved energy density and stability by using structural adhesive physically and wire bonding electrically.
Doosan Infracore has been developing battery packs after completing a feasibility review of the electric powerpack business last year. Having developed the prototype, it plans to manufacture an initial 1.7t electric excavator product with the battery pack after testing it while mounted on actual equipment.
“The battery pack can be mounted on all electrically driven vehicles, such as construction, mining and agricultural machines and golf carts,” a Doosan Infracore official said. “We have set an annual sales target of US$444M or more in the battery pack business by 2030.”
Previously, Doosan Infracore has successfully developed the company’s mild hybrid powertrain technology, a middle step between the internal combustion engine and the electric motor drive.
The hybrid powertrain adds electric motors and batteries to the internal combustion engine to offer power ignition, improved fuel rating and output, and reduced carbon emissions.
“We are Korea’s best engine manufacturer and have developed engines for vehicles, ships, industrial machines and military machines and for export to Europe including Germany, the leader in engines, and China,” said Sohn Dong-yeon, CEO of Doosan Infracore.
“We intend to become the leader in the global engine market by accelerating the development of hybrid powertrains and developing electrical drive technologies in this great paradigm shift in internal engines.”
