Model Y Emergency Response Guide
Battery Low-Voltage
In addition to the high voltage system, Model Y has a low voltage electrical system. Its 12V
battery operates the restraint system, airbags, windows, door locks, touchscreen, and interior
and exterior lights. The high voltage system charges the 12V battery, and the 12V battery
supplies power to the high voltage contactors, allowing high voltage current to flow into and
out of the high voltage battery. The 12V battery, outlined in red, is located under the hood and
the plastic access panel.
