Research on Anti-condensation Design of Charging Equipments

Abstract

Charging equipments for electric vehicles are directly installed outside. Condensation phenomenon would occur on the surface of charging equipments with rapidly changing of ambient temperature and humidity. The mechanism of dewing and harm of dew to electrical equipments in high humidity enviroment were studied in this paper. Four design shcemes were improved to solve the problem of dewing. Simulation test of condensation was accomplished by using high-low temperature chamber. The effect of four design schemes is tested and anlyzed to find the best anti-condensation scheme. Safety and reliability of internal electrical equipments are effectively guaranteed. The design scheme has important guiding significance for anti-condensation design of similar outdoor products.
