In 2023, Plug-in America released a survey of electric vehicle owners. One of the questions asked was, “What are the most significant concerns with existing fast-charging networks?” 46% of public DC Fast Charging network users considered broken or non-functional chargers the most significant problem1. One solution is to harden EV chargers from the impact of surges originating from thunderstorms or utility service interactions.
IEEE Std C62.230, titled “IEEE Guide for Surge Protection of Electric Vehicle Infrastructure,” provides guidance on effectively deploying surge protection at level 1 AC charging stations to DC fast chargers, hardening these systems from the impact of surges, resulting in increased reliability.

- IEEE Std C62.230™ target=”_blank”-2022: IEEE Guide for Surge Protection of Electric Vehicle Infrastructure
Developed By: Surge Protective Devices Committee of the IEEE Power and Energy Society
The application of surge-protective devices for electric vehicle infrastructure with system voltages of 1000 V ac or 1500 V dc or less is encompassed in this guide. The document provides guidance for North American types of electric vehicle supply equipment (EVSE) and electric vehicles (EVs) that conform to the SAE J1772: 2001. The guide includes applications such as power, data acquisition, and communications-related circuitry. The guide was developed for use by manufacturers, system designers, educators, and end users of electric vehicle supply equipment.
