1. A power supply control apparatus for a vehicle comprising:
a battery portion having a plurality of batteries of which a connection mode is switched to a series mode or a parallel mode; at least one device which can give or be given electric power to or from the battery portion; and a series/parallel switching portion which switches the connection mode of the plurality of batteries to a series mode or a parallel mode, the power supply control apparatus comprises: a plurality of series/parallel requiring portions which are provided individually for the battery portion and the device, and which output respective requirements of the battery portion and the device in relation to the connection mode of the plurality of batteries based on respective conditions of the battery portion and the device; a series/parallel requirement determination portion which determines which is greater in number between a series requirement and a parallel requirement in requirements outputted from the series/parallel requiring portions; and a series/parallel determination portion which determines the connection mode of the plurality of batteries to be a series mode or a parallel mode at least based on a determination of the series/parallel requirement determination portion, wherein the series/parallel switching portion switches the connection mode of the plurality of batteries to a series mode or a parallel mode based on a determination of the series/parallel determination portion.
