Global sales of EVs soared to over 17 million in 2024 which was a 25% increase from the sales in 2023. In electric vehicles (EVs), transducers are installed for a variety of purposes, including monitoring electric charge and managing electricity flow while EVs are charging.
 

With the increase in disposable income, consumers are more inclined towards purchasing high value products such as EV’s. The increased adoption of EV’s correlates with the increased demand for batteries. As a reference, in 2023 the global demand for EV batteries soared to over 700 gigawatt-hours (GWh) which was a 40% increase from the year 2022.
 

In addition, easement of other EV battery component parts such as automotive current transducer along with the positive government incentives for EV adoption enables further development. Current transducers help in monitoring charge and discharge cycles, thus increasing the life period of EV batteries. Therefore the demand for current transducers in the automotive industry will increase in the coming years, driven by the production of batteries.
 

Automotive Current Transducer Market Trends

The automotive current transducer industry has been experiencing a considerable upward shift, particularly because of the scaling necessity for electric vehicle battery energy management systems. This enhances several technological breakthroughs in the sector. Some of these technologies are Artificial Intelligence (AI) and Machine Learning (ML). These two apply for automating and improving energy utilization. Usage of energy is monitored in real time.
 

Moreover, AI and ML applies historical data to guide the transducers to identify possibilities for faults. Due to such advantages and increasing market need for sophisticated automotive current transducer technology, advanced metrology companies are compelled to develop powerful solutions.
 

Furthermore, due to rapid battery malfunction, a number of manufacturers had to withdraw electric vehicles to enhance its functionality. For example, General Motors withdrew over 50,000 Chevrolet Bolt EVs from their market in November 2020, which was later doubled in scope to include all Bolt models manufactured from 2017 to 2022, totaling 140,000 electric vehicles.
 

The issue was linked to the batteries from LG, which were later discovered to have short circuit and combustion defects. Current transducers monitor the battery for health and state of charge and discharge thereby eliminating the chances of shortening battery lifespan. Such cases will increase the adoption of current transducers for the automotive industry to better control the energy flow in the automotive current transducer market of focus.
 

For the purpose of reducing their carbon footprint and working towards global environmental preservation, many companies are using sustainable materials to design current transducers for the automotive industry. For instance, recyclable materials are being used in the manufacturing of the automotive current transducers. These efforts are financially beneficial because of the lowered cost of EV batteries from new material sourcing.
 

Additionally, using sustainable materials for sensor technologies in the current transducer design enhances sustainability further. Many sensor manufacturing companies are developing low power, coreless sensors or lightweight sensors, making the sensors more affordable and reducing energy consumption. All of these actions helps to meet the demand for automotive current transducers.
