APRO Co., LTD. develops, manufactures, and supplies specialized manufacturing and testing equipment for lithium-ion secondary batteries, alongside advanced power electronics and wide-bandgap semiconductor technologies. The company primarily serves tier-one battery cell manufacturers, electric vehicle joint ventures, and energy storage system producers globally. Its comprehensive product and service portfolio includes: high-temperature pressurized formation systems; room-temperature formation chargers and dischargers; degassing and vacuum sealing equipment; internal resistance and open-circuit voltage inspection systems; high-precision battery cyclers; cell aging, sorting, and grading machines; automated end-of-line test systems; gallium nitride power semiconductor devices; eight-inch gallium-nitride-on-silicon epitaxial wafers; switched-mode power supplies and power conversion systems; and fully integrated turnkey automation lines for pouch and prismatic battery finishing.
Founded in 2000, APRO Co., LTD. is headquartered in Gunpo-si, Gyeonggi-do, South Korea, with domestic research and manufacturing facilities in Gumi and Gunpo. The company maintains an international operational and field-support footprint across major battery manufacturing corridors in the United States, Poland, and China through regional subsidiaries such as APRO Service LLC and APRO Service Poland Sp. z o.o., as well as its specialized semiconductor subsidiary, A-PRO Semicon Co., Ltd.
In recent strategic developments, APRO Co., LTD. has accelerated the vertical integration and commercialization of its next-generation wide-bandgap power semiconductor business through A-PRO Semicon, achieving high-voltage gallium nitride epitaxial wafer development and securing selection for national deep-tech scale-up acceleration programs. The company has systematically integrated these in-house gallium nitride power components into its high-temperature pressurized formation equipment to improve energy efficiency, thermal management, and equipment footprint. Additionally, the company has broadened its global engineering presence across North America to execute large-scale supply and commissioning agreements for major gigafactory projects, including Ultium Cells manufacturing lines, while expanding its business scope into electric vehicle fast-charging power modules and diagnostic systems for retired secondary battery reuse and recycling.
