SEG Automotive

What SEG Automotive does

SEG Automotive is a global tier-1 automotive supplier specializing in rotating electric machines and powertrain electrification components. The company manufactures starter motors, generators, 48V mild hybrid systems (BRM), high-voltage e-machines and inverters, light electric mobility drive systems, and eBike mid-motors for vehicle manufacturers and the independent aftermarket. Founded in 1914 as part of Robert Bosch GmbH's Starter and Generator division, the company was spun off in 2018 and is now privately held under Chinese investor Zhongchuang Zhiling, operating from Stuttgart, Germany.

The business serves four primary segments: passenger car and commercial vehicle OEMs (including Toyota, Ford, GM, Stellantis, the Volkswagen Group, and the Renault-Nissan-Mitsubishi Alliance), light electric mobility OEMs (e-scooters, e-rickshaws, microcars), bicycle manufacturers (BH Bikes, Van Dijck, with Octagon collaboration), and the independent automotive aftermarket (dealers, workshops, and remanufacturing channels). Revenue is generated through B2B hardware sales under multi-year OEM supply contracts, aftermarket parts distribution via a B2B online shop, and engineering services spanning concept-to-mass-production support.

The company operates from 14 countries with manufacturing sites in Germany, Spain, Hungary, Portugal, China (Changsha and Changchun), India, Brazil, Mexico, the United States, and South Africa, plus dedicated sales offices in Japan, South Korea, France, and Italy. Approximately 6,000-6,500 employees support a portfolio spanning 12V to 800V systems, with technology differentiation anchored in over a century of electromechanical expertise, EU Eco-innovation certification on the 48V BRM platform, vertically integrated inverter production, and the emerging Redrive remanufacturing concept for high-voltage EV drive units co-developed with FERSA.
