IP or NEMA: Which Enclosure Rating is More Important When Designing Electric Vehicle Charging Stations?
A recent update from the Biden Administration revealed that there are more than three million EVs on the road in the U.S., and more than 130,000 EV charging stations currently in use. The President’s goal is for EVs to make up 50% of all new car sales by 2030, and this benchmark also calls for a nationwide network of more than 500,000 EV charging stations. IP and NEMA ratings certify an enclosure’s capacity to perform in harsh environments, but the unique nature of EV charging stations can leave designers a little unclear as to which rating system carries more weight for this kind of application.
