System Main Relay 2

The system main relay 2 is integrated in the Li-ion battery and controlled by VCM. The system main relay 2
connects and disconnects the high-voltage circuit (-) side and Li-ion battery. When high voltage power is supplied, VCM activates the system main relay 2 to supply power from the Li-ion battery to the EV system. When charging, power from an external charger is supplied from the system main relay 2 to the Li-ion battery.
