Abstract

A vehicle electric battery controlling apparatus is applied to a vehicle including an on-board charger to charge a battery in the vehicle with power supplied from an external power source, a heater to warm the battery, and a DC-DC converter to reduce the voltage of power from the battery and then supply the battery power to the heater. The vehicle electric battery controlling apparatus includes a DC-DC converter controller to drive the DC-DC converter to supply the battery power to the heater before the charge of the battery by the on-board charger, and an on-board charger controller to drive the on-board charger such that the power source for the heater is gradually shifted from the battery to the external power source, after the DC-DC converter is driven.
