Abstract
A vehicle control apparatus mounted on a vehicle including a DC-DC converter that supplies electric power from a first battery to a second battery and an auxiliary load includes an electronic control unit configured to control an operation of the converter, determine a state of a starter switch of the vehicle, detect a user operation to the vehicle, and acquire charging status information of the second battery. The electronic control unit is configured to, when the electronic control unit detects a first operation by the user and determines that the starter switch is off, drive the converter such that the converter charges the second battery, and, when an electric power amount charged in the second battery reaches a target amount of charge set based on an amount of electric power to be consumed by the auxiliary load while the starter switch is off, stop the converter.
