High-power direct current charging system

Abstract

A high-power direct current, HPDC, charging system for charging electric vehicles is provided. The HDPC charging system comprises a housing that defines a sealed compartment and a chimney compartment. It further comprises heat-generating electrical components located within the sealed compartment. The HDPC charging system is configured to deliver an output power of 20 kilowatts or more. The housing includes a thermally conductive portion providing thermal transfer between the sealed compartment and the chimney compartment. The housing further comprises a lower inlet opening and an upper outlet opening that enable an airflow between the chimney compartment and ambient air. The chimney compartment defines a substantially vertical airflow path from the lower inlet opening to the upper outlet opening passing along the thermally conductive portion. The sealed compartment is airtight relative to the chimney compartment and to ambient air.
