We are building a 750 W battery charger for EV applications. Following is the brief specification.
Input voltage :- 170 to 270 V AC
Output Voltage :- 35 to 58 Vdc
Output current :- 12.5 A
To evacuate the heat we are using a potting material the datasheet of which I have attached here. During the ambient operating (25 degree) conditions, the maximum internal ambient goes upto 110 to 115 degree. Most of the critical parts are are at this elevated temp such as capacitors ,ICs etc After doing the potting & testing we are observing some abnormal behaviour during the higher ambient conditions such as current loop going out of the control & CAN communication discontinuation etc.
Can anyone suggest the suitability of the potting material selected ?
