EV battery electrical components and high-voltage systems for Chinese automakers
由甲申田designs and manufactures critical electrical components for EV battery systems—temperature sensors, manual switches, and high-voltage relay modules—sold to Chinese independent automakers. The company runs a Siemens/Mitsubishi automation stack (S7-1200/S7-1500 PLCs, MES, CAD) paired with automotive quality frameworks (IATF 16949, APQP, FMEA, SPC), indicating a mature tier-1 supply operation. Engineering dominance (19 of 27 open headcount) combined with active pain points around procurement cost, production defects, and inventory turnover suggests they're scaling manufacturing capacity while optimizing supply-chain economics.
由甲申田, founded in 2012 and based in Shanghai, is a vertically integrated automotive supplier specializing in electrical subsystems for battery-electric vehicles. The company develops and manufactures temperature sensors, manual maintenance switches, and high-voltage relay assemblies that integrate into battery management and distribution architecture. Customers are Chinese EV OEMs and independent brands. Operations span product design (CAD-driven), manufacturing (MES/PLC-controlled), and quality assurance (IATF/APQP compliance), with 51–200 employees focused on engineering and production. Current projects center on high-voltage harness design, battery distribution box development, and new production line setup.
