PROBLEM TO BE SOLVED: To provide a power supply device which enables easy handling during shipping and transportation.SOLUTION: A power supply device includes: a battery pack 3; an electric connection box 6; a voltage transducer 7; an ECU 8; and a housing 4. The battery pack 3 comprises electric cells 2. The electric connection box 6 has an electric connection circuit including a relay which switches a connection state between the battery pack 3 and a load. The voltage transducer 7 has a voltage conversion circuit which coverts a voltage output from the electric connection circuit and outputs the voltage. The ECU 8 has a control circuit which controls the electric connection circuit and the voltage conversion circuit. The housing 4 houses the battery pack 3, the electric connection box 6, the voltage transducer 7, and the ECU 8.SELECTED DRAWING: Figure 1 |
