According to our (Global Info Research) latest study, the global Automotive Current Transformers market size was valued at US$ 128 million in 2025 and is forecast to a readjusted size of US$ 185 million by 2032 with a CAGR of 5.4% during review period.
Automotive current transformers (CTs) are electrical measurement devices specifically designed for vehicle power and electronic control systems. They operate on the principle of electromagnetic induction to convert high current signals into proportionally lower current outputs, which can be used for current monitoring, energy measurement, protection, and control. Their main functions include current detection, overcurrent protection, energy monitoring, and closed-loop control, and they are widely applied in battery management systems (BMS) of electric vehicles, automotive DC-DC converters, inverters, motor drive systems, and onboard chargers (OBC). Automotive current transformers typically employ a closed magnetic circuit or split-core design. Key design considerations include rated current, turns ratio, frequency response, isolation performance, and automotive-grade reliability, ensuring reliable operation under high temperature, vibration, and long-term automotive conditions. They are critical components for safe, efficient, and intelligent operation of vehicle high-voltage and low-voltage electrical systems.
The upstream of the industry chain mainly includes suppliers of raw materials such as magnetic materials (e.g., silicon steel sheets, ferrite, amorphous/nanocrystalline magnetic cores), conductors (copper wire, enameled wire), insulation materials, and encapsulating resins, as well as suppliers of winding equipment, magnetic core processing equipment, and testing instruments, providing a fundamental guarantee for the production of current transformers. The midstream consists of current transformer design and manufacturing companies, responsible for magnetic core processing, coil winding, encapsulation, insulation treatment, and performance testing. Their product types cover closed magnetic circuit type, open (open/detachable) type, and high-precision modular current transformers, widely used in high-voltage battery management systems (BMS) for new energy vehicles, on-board DC-DC converters, inverters, motor control modules, and on-board chargers (OBC). The downstream consists of OEMs and automotive electronics module manufacturers, who impose stringent requirements on on-board current transformers, including high-precision measurement, high linearity, fast response, isolation safety, and automotive-grade reliability, to ensure the safe, stable, and efficient operation of the power supply and control systems of new energy vehicles and intelligent vehicles.
In 2025, global sales of automotive current transformers will reach 16 million units, with a production capacity of approximately 23 million units. The average selling price is US$7.8 per unit, and the average gross profit margin is 25%-35%.
The demand for automotive current transformers primarily stems from new energy vehicle high-voltage battery management systems (BMS), on-board DC-DC converters, inverters, motor control modules, and OBC chargers. Among these, high-voltage electronic control platforms and bidirectional energy feedback systems for new energy vehicles are the core drivers of growth. Simultaneously, the demand for precise current detection and EMI suppression from on-board intelligent driving systems (ADAS) and infotainment systems continues to grow. Overall demand exhibits three major trends: high precision, high power, and intelligence.
Automotive current transformer technology is evolving towards higher precision, lower leakage flux, higher frequency response, miniaturization, and modular packaging. Core materials are being optimized to ferrite or nanocrystalline/amorphous materials, satisfying both high-frequency characteristics and ensuring high current carrying capacity. Closed magnetic circuits and split-core designs are widely adopted to achieve fast response and high linearity. Surface mount technology (SMD) and modular integration designs are gradually becoming the trend, saving PCB space and facilitating system integration.
