Abstract
A vehicle electric power supply apparatus includes: a first battery that supplies electric power to a first load that is driven at a first voltage and a second load that is driven at a second voltage which is lower than the first voltage; a second battery that supplies electric power to the second load and that has a lower output voltage than that of the first battery; a DC/DC converter that reduces a voltage value of the first battery and that supplies electric power to the second load; and a control part that controls a state of supplying electric power of the first battery to the second load by controlling an operation of the DC/DC converter based on a charging rate of the first battery and a charging rate of the second battery.
