PROBLEM TO BE SOLVED: To provide an automobile power supply device which can stably supply electric power to a load, even if either one of two batteries fails during normal traveling and regenerative controlling.SOLUTION: An automobile power supply device includes: a main battery 1; a sub battery 7; a first load group 4 and a second load group 9 to which power is supplied from the main battery and the sub battery; an alternator 3 which operates during normal travelling or regenerative operation to supply charging power to a first battery and a second battery; a starter motor 2 to which power is supplied from the main battery; and a power supply control section 8 which controls whether the main battery and the sub battery should be connected to the first and second load groups. The power supply control section 8 puts the main battery 1 and the sub battery 7 and the first and second load groups 4 and 9 in a connection state, during the normal traveling and the regenerative operation.SELECTED DRAWING: Figure 1
