Many current transducers are on the market, each suited to specific applications within EV charging systems. These include:

• Hall-effect transducers are known for being cost-effective and compact. These transducers are widely used but can have limitations in accuracy, particularly at high currents. Their adaptability to compact configurations makes them suitable for less demanding scenarios. 
• Rogowski coils are non-intrusive and flexible transducers that excel in high-current applications. Their lightweight and flexible design makes them ideal for applications requiring ease of integration and minimal physical impact on the system.
• Shunt resistors arehighly precise in measuring currents and are often used in scenarios requiring detailed current monitoring. However, their performance can degrade in high-power situations due to heat-related issues, making them less ideal for heavy-duty EV charging systems.

Fluxgate transducers based on the fluxgate principle are fantastic for more demanding EV charging applications, as they offer high accuracy and stability across wide temperature ranges. They are particularly effective for modern EV charging systems where precision and reliability are critical.
