The global current sensor market size was valued at USD 2.18 billion in 2023 and is projected to reach USD 4.24 billion by 2030, growing at a CAGR of 10.1% from 2024 to 2030. This strong growth trajectory reflects the increasing demand for accurate and reliable current measurement solutions across multiple industries. The rise of electric vehicles (EVs) is one of the most significant drivers of the market. As the automotive industry rapidly shifts toward electrification, the need for precise current measurement in critical components such as battery management systems and motor control units has increased substantially.

Current sensors play a crucial role in monitoring the state of charge, current flow, and overall health of EV batteries, helping to ensure optimal performance, safety, and extended battery life. In addition, accurate current measurement supports the efficient operation and control of electric motors, which are fundamental components of EV powertrains. These sensors enable better energy utilization, reduced losses, and enhanced vehicle reliability. As the global adoption of electric vehicles continues to accelerate, supported by government incentives and stricter emission regulations, the demand for advanced and high-performance current sensors is expected to grow steadily.

The expansion of renewable energy sources is also contributing significantly to the growth of the current sensor market. Solar and wind power systems require efficient energy conversion, monitoring, and management to maximize output and minimize losses, all of which depend heavily on precise current measurement. Current sensors are widely used to monitor the output of solar inverters and wind turbines, helping optimize system performance and ensure stable power generation. Furthermore, energy storage systems, which are essential for balancing supply and demand in renewable energy infrastructures, rely on current sensors to monitor charging and discharging cycles and maintain system efficiency. As global efforts intensify toward adopting cleaner and more sustainable energy solutions, the demand for current sensors in renewable energy applications is expected to rise significantly.
