1. An electric vehicle supply equipment (EVSE) that includes a thermal management system, comprising:
a dual-sided heatsink, including:
a first side that faces internal ambient air of the EVSE, wherein the internal ambient air of the EVSE is heated by electronic components of the EVSE, and wherein no electronic components of the EVSE are directly connected to the dual-sided heatsink, and
a second side that faces external ambient air;
a first fan that circulates the internal ambient air of the EVSE across a length of the first side of the dual-sided heatsink to reject heat from the internal ambient air into the first side of the dual-sided heatsink that in turn conducts to the second side of the dual-sided heatsink;
a first airflow guide that guides the internal ambient air across the length of the first side of the dual-sided heatsink;
a second fan that draws external ambient air that flows across a length of the second side of the dual-sided heatsink to reject heat from the second side of the dual-sided heatsink out of the thermal management system, wherein heat from the second side of the dual-sided heatsink conducts to the external ambient air;
a second airflow guide that guides external ambient air across the length of the second side of the dual-sided heatsink; and
an airflow seal that prevents the external ambient air and the internal ambient air from mixing.
