Analisis Material Efoxy EF150K Terhadap Temperatur dan Kelembaman Tinggi Pada Komponen Charger Mobil Listrik

Abstract

Electric cars have now been made and developed by famous car manufacturers outside of Indonesia. Of course electric cars have batteries that must be recharge. Inside the electric car charger there is a controller which is one of the components, which is an epoxy coated capacitor. The faster the charger, the higher the temperature will be, to deal with this problem, it is necessary to increase the performance of the capacitor to increase the temperature and humidity resistance. Then from this explanation the researchers will test the EF150K epoxy coating on the Disc Ceramic Capacitor (DCC), by using epoxy coating thickness testing by using 3 samples the results obtained are on average 0.8 mm, Pressure Cycle Test (PCT) using 20 samples with conditions temp: 121 °C, p: 2 bar for 48 hour, obtained average capacities and insulance resistance before PCT testing C: 2155,4pF, IR: 141540Ω and after C: 2238,2 pF, IR: 147140 Ω, and humidity test using 20 sample with condition 95% RH, temp: 40°C for 504h obtained average capacities and insulance resistance before humidity test C: 2.157,89 pF, IR: 119560 Ω and after C: 2.233,63 pF, IR: 123160 Ω. The use of EF150K epoxy is very well used as a DCC capacitor coating, because the coating is resistant to temperatures up to 121 ° C with a pressure of 2 bar, and withstands temperatures up to 40 °C with 95% RH.
