12 VOLT BATTERY
In addition to the high voltage system, Model S has a low voltage electrical system. Its 12 volt battery operates the SRS, airbags,
windows, door locks, touchscreen, and interior and exterior lights. The DC-DC converter in the high voltage system charges the 12 volt
battery, and the 12 volt battery supplies power to the high voltage contactors, allowing high voltage current to flow into and out of the
high voltage battery. The 12 volt battery, outlined in red, is located under the hood and the plastic access panel.
