Provided is a power supply device for vehicles that can prevent uneven consumption of batteries when an equalizer and a disconnect switch are combined for use, the power supply device for vehicles including a power supply circuit in which a low voltage load circuit and a high voltage load circuit are connected to a plurality of batteries connected to each other in series. A power supply circuit (11) includes an equalizer (19) that can prevent uneven consumption of each battery (12, 13); a disconnect switch (22) that enables the battery (12) on the low voltage side to be electrically cut off; and a disconnect relay (23) that enables the battery (13) on the high voltage side to be electrically cut off. A machine controller (26) starts an engine controller (28) by turning on an engine key relay (27) after turning on the disconnect relay (23).
