Abstract
A power distribution device comprises a system main relay, i.e., SMR, a pre-charge circuit and a control board. The SMR selects between on and off of a current between a power conversion device and a battery. The pre-charge circuit includes a charge resistor and a charge switch which are provided to charge the smoothing capacitor with power supplied from the battery. The control board enables a current smaller than a current flowing through the SMR. The SMR and the control board are arranged in the x-direction via the pre-charge circuit.
