DC/DC Junction Box: Notes
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.
