DC-DC Converter

Instead of using an alternator to maintain the 12 volt battery, the electrical system uses a DC-DC converter. The converter converts high voltage direct current into low voltage direct current with little energy loss.

If a problem is detected in the 12 volt charging system, the DC-DC converter turns on the charging system indicator by sending a signal to the gauge control module via the MCM.

The DC-DC converter has a built-in temperature sensor and temperature information is sent to the MCM. When DC-DC converter temperature rises, the MCM drives the IPU module fan. If the DC-DC converter temperature rises abnormally, DC-DC converter output is limited. If the temperature continues to rise, the DC-DC converter output is stopped.

Heat generated by the DC-DC converter is exhausted to the cargo area by the IPU module fan.
