Relays Play a Key Role in EV Charging System

Energy is indispensable to our life and society. How to effectively use limited energy resources has become a significant future challenge. Under such circumstances, great importance is placed on energy management systems whose aim is to achieve a sustainable energy society. In fact, high capacity relays play a behind-the-scenes role in the support of such energy management. This time, the role of high capacity relays and such product information will be introduced focusing on the three representative applications of energy management systems, namely charging stations, power storage systems, and inverters.

Relays used for AC side circuits (for switching alternating current loads) are required to provide high capacity AC cutoff capabilities and high reliability since they are used as safety cutoff relays in power grids to prevent anomalies in consumer side circuits from impacting commercial power supply circuits.

The availability of EV charging stations is key to the continued adoption of EVs, and developers face numerous challenges designing for higher voltage and power levels while meeting increasingly stringent efficiency targets. Relays play an important role in the safety of EV charging systems, and the development of PCB mounted relays offers benefits in terms of cost, reliability, and space. Until now, PCB relays have been limited to low voltage level applications, but the IVY IM-NE801A relay is able to handle 40A, representing a true breakthrough in EVSE design.
