Doosan Infracore According to the company, a prototype battery pack for construction and agricultural equipment has been developed that will be used for the expected release of a 1.7-ton DX17Z-5 electric excavator early next year.
(While it was unveiled at the Doosan Infracore North America booth at ConExpo 2020, according to Doosan sources, the DX17Z-5 won’t hit North America until 2023. The company currently offers six compact excavators in North America, from 8,193 pounds to the DX35-5 18,960 pounds DX85R-3.)
The battery packs consist of battery modules and a battery management system and a cooling system that are connected in a frame. Doosan says this development can accelerate both the battery business and its own electrified products.
According to the company, the battery is flexible and uses standardized cylindrical battery cells to adjust the voltage and capacity of a machine. The battery management system uses standardized designs so that the packs can be configured with up to 32 modules “regardless of series or parallels”, according to the company. The battery cells are bonded with a structural adhesive and wire bonding technology improves energy density and stability.
Doosan InfracoreThe company aims to sell its batteries for $ 448 million by 2030. The company is also looking at the batteries for golf carts and other electrical devices.
Doosan Infracore previously announced the development of its Mild Hybrid Powertrain technology, which is seen as an intermediate step between an internal combustion engine and electrification. This technology uses an electric motor and battery in a diesel engine, and the company says it “can improve fuel economy, improve performance and reduce carbon emissions with strong startability”.
The company continues, “In the midst of a major paradigm shift, we will accelerate the development of hybrid propulsion and electrification technology to establish ourselves as the global engine market leader.”
