PREMO release cutting-edge inductive couplers for Electric Vehicle Sniffing / CCS listener applications, revolutionizing high-voltage system monitoring. New MICU 300A-S/LF Series.

PREMO, a leading manufacturer of inductive components, has unveiled its latest breakthrough product – the MICU 300A-S/LF series of inductive couplers, designed specifically for electric vehicle sniffing applications.

With the rise of electric vehicles on our roads, there is a growing need for reliable and accurate sniffing solutions to monitor the performance and safety of their high-voltage systems. PREMO’s cutting-edge MICU 300A-S/LF series provides a non-intrusive solution for this purpose. The MICU series offers an extended frequency range and minimal insertion loss providing combined narrow-band (30-600kHz) and broadband (2MHz-40MHz).

They are easy to install and use, with a sleek and compact design that makes them ideal for use in rugged environments. SW equipment can be connected through different connectors (BNC standard/others under demand). Mechanical latch ease installation over cables up to 45mm diameter (current rate up to 300A, including shielded cables). “We are thrilled to launch our innovative line of inductive couplers for electric vehicle sniffing applications,” said Jordi Mestre, CTO of PREMO. “As the world shifts towards sustainable transportation, we are committed to providing high-quality solutions that support the safe and efficient operation of electric vehicles, suitable for different markets: European, American and Asian.

Non-intrusive solution (by PLC sniffer: MICU 300A) for monitoring PWM basic communication parameters

Electric vehicles (EVs) are becoming increasingly popular due to their environmental benefits and cost savings. However, they also present unique challenges when it comes to monitoring their high-voltage systems. This is where sniffing applications come in. Sniffing involves the use of inductive couplers to measure the current and voltage signals on high-voltage cables, without the need for direct contact with the cables themselves. This non-intrusive method of monitoring is critical for ensuring the safe and efficient operation of EVs. Sniffing applications are essential for a variety of reasons. Firstly, they allow for real-time monitoring of the high-voltage system, providing valuable insights into its performance and safety. Secondly, they can help identify potential issues before they become serious problems, allowing for timely maintenance and repair. Finally, they can be used to gather data for research and development purposes, helping to improve the overall performance and efficiency of EVs.

PREMO’s MICU 300A-S/LF series of inductive couplers has been specifically designed for use in sniffing applications for electric vehicles. They are also easy to install and use, with no need for calibration or setup.

Innovative core material and overmolded insulation material reach high voltage protection (up to 5kV) and EV charging quality standards (HomePlug, V2G, etc.), making them suitable for listen CCS (Combined Charging System) communication protocol between a charging station (EVSE) and an electric vehicle (EV): ISO/IEC 15118, DIN70121 and IEC 61851-1. Can be used outdoors due to waterproof (IP67) versions.

Premo is committed to SDGs (United Nations Sustainable Development Goals) and designs, engineers, prototypes, and tests full reliability at its green carbon net positive Innovation Center. MICU products are thus engineered under sustainability standards that design for the circular economy, considering 0km materials of natural origins, using green energy, and minimizing the content of polymers from fossil fuels as well as recycled ferrites and copper.

This innovation will be presented at PCIM Europe 2023 at PREMO Stand Hall 6, Stand 232.

The MICU 300A-S/LF series is now available from PREMO’s global network of distributors.
