In normal charge, the battery is charged through the On-Board Charger (OBC) using external power supply of 220V.
On-Board Charger (OBC) is the equipment that charges the high
voltage battery of electric vehicle using the 110 ~ 220V AC power. Its
maximum output is 6.6 kW and the efficiency is about 91%.

Description
Main Relay is installed in the Power Relay Assembly (PRA) and it controls the high voltage line.
It connects the power between the high voltage battery pack and the high voltage joint box by the BMS ECU control signal.
But when the battery cell is swollen by overcharging, main relay ...
