During operation, charging modules, power components, and control elements generate heat. Enclosure design must determine natural ventilation, fans, heat sinks, or other thermal management methods based on heat dissipation, operating time, ambient temperature, and installation location.

Outdoor EV chargers must also withstand rain, dust, moisture, UV rays, condensation, and vehicular environments. Doors, displays, connectors, cable glands, bases, and vents all impact overall ingress protection. This article covers enclosure design for sealing, drainage, heat dissipation, cable entries, and maintenance, noting that final IP ratings require complete assembly testing.
