Dc/Dc Junction Box

COMPONENT PARTS

DC/DC Junction Box






The DC/DC junction box integrates a DC/DC converter to supply electric power to the 12 V power system and charge the 12V battery in addition to distributing high voltage power from the Li-ion battery to systems.
The DC/DC junction box has a normal charge relay and a quick charge relay so that the circuits are changed over according to the charge mode.
The DC/DC junction box has an internal cooling fin used to cool the
DC/DC converter by water cooling.

DC/DC CONVERTER

The DC/DC converter steps down the high voltage DC current of the Li-ion battery to a 12 V DC current, which is used to supply power to the 12 V electrical system and charge the 12V battery. In addition, the DC/DC converter changes the output voltage according to VCM signals so that appropriate voltage is supplied depending on the vehicle condition.
