As Electric Vehicle (EV) popularity continues to grow, the barrier to their continued adoption has shifted from range to charging. Availability of charging stations and the need for low charging times has put industry focus on Level 3 fast chargers. However, higher power and voltage level requirements place new demands on components within charging systems, including relays that are critical to overall functional safety.

In this week’s Engineers’ Insight, Adam Losonczy explains the key role relays play in EV charging applications and breaks down the factors that designers need to consider when selecting them.
