According to our (Global Info Research) latest study, the global Automotive Start-Stop Power Supply market size was valued at US$ 3962 million in 2025 and is forecast to a readjusted size of US$ 5083 million by 2032 with a CAGR of 3.6% during review period.
In 2025, global Automotive Start-Stop Power Supply production reached approximately 11.32 million units, with an average global market price of around US$ 340 per unit.
An automotive start-stop power supply is an onboard power unit designed to support start-stop systems by delivering high transient cranking power, stable low-voltage supply, and voltage hold-up during frequent engine stop/restart events. Working with 12V (or 24V) electrical architectures and starter/BSG/ISG systems, it ensures fast restart capability while maintaining stable voltage for critical electronics (ECUs, lighting, steering assist, pumps, infotainment, etc.), improving fuel efficiency, drivability, and electrical reliability.
The upstream sector primarily includes battery cells and energy storage media (EFB/AGM lead-acid systems, lithium-ion cells, or supercapacitors), key materials (lead ingots and alloys, sulfuric acid electrolytes, separators/glass fiber membranes, aluminum/copper foil, conductive carbon materials, plastic casings and flame-retardant materials), power and control devices (MOSFETs/IGBTs, DC-DC magnetic components, relays/fuses, BMS/monitoring ICs, wiring harnesses and connectors), and manufacturing equipment and testing systems. The midstream sector comprises power supply/battery manufacturers that manufacture battery cells/packs, implement BMS and power management strategies, thermal management and structural design, and lifespan and safety verification, supplying OEMs or Tier 1 suppliers. Downstream applications cover passenger vehicles and light commercial vehicle platforms equipped with start-stop functionality. Representative upstream ecosystem examples include Umicore, BASF (battery materials/chemical systems), Infineon, STMicroelectronics (power semiconductors), and TE Connectivity (connectors). Representative downstream application companies include Clarios, Exide, GS Yuasa, CATL, and OEM platforms such as Toyota, Volkswagen, and Stellantis.
The annual production capacity of a single-line Automotive Start-Stop Power Supply is approximately 200k units, with a gross profit margin of approximately 15%-30%.
