What AES-KY does

AES-KY (Advanced Energy Solution Holding Co., Ltd.) is a Cayman Islands–incorporated holding company listed on the Taiwan Stock Exchange under stock code 6781 (listed March 22, 2021) and a subsidiary of Simplo Technology Group. The company designs, manufactures, and sells power lithium-ion battery modules and energy storage lithium-ion battery modules for global brand customers, with end applications concentrated in light electric vehicles (electric bicycles, electric scooters, electric balance vehicles), data center backup (BBU modules), and industrial/residential energy storage systems. Operations are anchored in Taiwan (Hsinchu County headquarters and Jiapu Technology subsidiary) and mainland China (Taipu Power New Energy (Changshu) Co., Ltd.), with wholly-owned manufacturing in Vietnam and sales/business development subsidiaries in Singapore and Kentucky, USA.

The technology base is built around four light-EV product series — Slim Tube (21700 cells, 360–800Wh), In-Frame Tube (18650 cells, 500–800Wh), Range Extender (18650 cells, 250–360Wh), and Rear Rack — engineered for compatibility with Shimano Gen1/Gen2 and Yamaha drivetrain ecosystems. A custom in-house Battery Management System (BMS) is integrated into each module, and an in-house national-level laboratory conducts reliability, performance, safety, and aging testing. The company holds IATF 16949 automotive certification, ISO 9001/14001/45001/50001/27001/14064-1, TISAX, and RBA VAP Silver; subsidiary Zhaopu co-authored the EPD Product Category Rules (PCR) for lithium-ion secondary battery packs through the Taiwan Battery Association, and the company's BBU module holds the world's first third-party-verified (UL, ISO 14025) Environmental Product Declaration in this category.

AES-KY runs a B2B enterprise field sales model, engaging global brand customers directly through its own sales, engineering, and project management teams without channel intermediaries; the company conducts roughly 50 customer on-site audits per year and quotes custom pricing under multi-year contracts. Customer segments are primarily light electric vehicle manufacturers, with secondary exposure to data center operators (BBU) and industrial energy storage buyers. Reported 2025 full-year accumulated revenue was NT$16.0 billion (~USD $509M), up 59.42% YoY from NT$10.04 billion in 2024, reflecting strong pull from light-EV and energy storage demand. Bank SinoPac as custodian for Trend Power Technology Holdings (Samoa) holds 54.77%, indicating concentrated control through the Simplo Group's offshore holding vehicle.
