The rising demand for electric vehicles is expected to drive the growth of the automotive uninterruptible power supply (UPS) (in-vehicle UPS) market in the coming years. Electric vehicles (EVs) are powered by electric motors using energy stored in batteries, offering a cleaner alternative to traditional internal combustion engine vehicles. This demand is fueled by growing environmental concerns, government incentives for cleaner transportation, advancements in battery technology, and a desire for energy independence. Automotive UPS systems ensure uninterrupted power delivery in EVs, enhancing reliability and protecting sensitive onboard electronics. For instance, in April 2024, the International Energy Agency (IEA), a France-based intergovernmental organization, reported that new electric car registrations in China reached 8.1 million in 2023, marking a 35% increase compared to 2022. Therefore, the increasing adoption of electric vehicles is supporting the growth of the automotive UPS market.

Leading companies in the automotive UPS market are focusing on technological innovations, such as silicon carbide (SiC) MOSFET trench technology, to gain a competitive edge. SiC MOSFET trench technology involves creating vertical trenches in the SiC substrate to achieve lower on-resistance and higher efficiency in power switching applications. For example, in February 2024, Infineon Technologies AG, a Germany-based semiconductor manufacturer, launched the 750V G1 discrete CoolSiC MOSFET family to meet the rising demand for higher efficiency and power density in industrial and automotive power systems. This product line includes both industrial-grade and automotive-grade SiC MOSFETs optimized for a variety of topologies, including totem-pole PFC, T-type, LLC/CLLC, dual active bridge (DAB), HERIC, buck/boost, and phase-shifted full bridge (PSFB).

In June 2025, ILJIN Electronics, an India-based electronic services company, acquired a majority stake in Power-One Micro Systems Pvt Ltd for an undisclosed amount. This acquisition enables ILJIN Electronics to expand its presence in the rapidly growing energy solutions and power-electronics market, strengthening its offerings in UPS, battery-energy storage systems (BESS), EV charging, solar inverters, and related clean-energy products. Power-One Micro Systems is an India-based provider of power conversion and conditioning solutions, including UPS systems, BESS, EV chargers, and other energy-storage and power-electronic solutions.
