Abstract
A battery charging control method for a vehicle may include: a failure determining step of determining, by a controller, whether a first voltage converter and a second voltage converter equipped in the vehicle are broken; a charging requiring determining step of determining, by the controller, whether an auxiliary battery needs to be charged when the first voltage converter and the second voltage converter are not broken; and a charging step of charging, by the controller, the auxiliary battery by connecting an input terminal of the auxiliary battery to an output terminal of the first voltage converter outputting a voltage higher than a voltage of an output terminal of the second voltage converter and operating an electric load by connecting an input terminal of the electric load of the vehicle to the output terminal of the second voltage converter, when the auxiliary battery needs to be charged.
