What Pihsiang Energy Technology does

Pihsiang Energy Technology Co., Ltd. (PHET, Taipei Exchange Emerging Stock Board stock code 6551) is a Taiwanese LiFePO4 battery manufacturer founded in November 1998 and headquartered in Hsinchu Industrial Park, Taiwan. The company designs and manufactures 18650 cylindrical cells (Power Cell SP1100 for high-power applications and Energy Cell EP1500 for energy applications), battery modules across E, D, and R series (4Ah to 224Ah), standard 12V and 24V LiFePO4 battery packs, and customized energy storage systems (ESS) including UPHICA3P2, UPINFN12, UPSC12, and UPCR48 for naval, military, telecom backup, medical, and renewable energy storage applications. The technology stack is built on three world-patented proprietary systems: DOSBAS® fault-tolerant safety architecture that isolates damaged cells via quick-blown fuses to prevent thermal runaway propagation, DOBPCS® automatic charging balance system for long-term cell equilibration, and INFINITILINKS® modular extension technology enabling serial/parallel pack scaling to arbitrary voltage and capacity.

The company operates a vertically integrated "Total Solution" model spanning single cells, battery modules, BMS, charging systems, and mechatronics integration, sold primarily B2B through direct sales to enterprise and government customers supplemented by channel partnerships (notably Fubank Holding and Ningbo Sonluk Holding Group in China) and ACHENSA®-branded micro electric vehicle exports to Europe. PHET holds UL1642, ISO 9001:2008, RoHS (SGS), and ITRI EV certifications, and serves customers in electric vehicle manufacturing, grid-scale energy storage, naval/defense, and telecommunications. Reference customers include the Russian government (exclusive Mars Project battery supplier appointed August 2010) and various naval/military forces. Current annual production capacity stands at approximately 20 million Ah with stated plans to scale to 150 million Ah. The company employs approximately 120 staff members and reports total paid-up capital of NT$1.94 billion.
