Abstract

A power supply control device includes: a control board that is configured to control a voltage of a battery module; and a bus bar module that is configured to electrically connect the control board and the battery module, the control board and the bus bar module are arranged in a stacked manner, and connection terminals of the bus bar module which are connected to the battery module are exposed when viewed from the control board.

Claims

1. A power supply control device, comprising:

a control board that is configured to control a voltage of a battery module; and

a bus bar module that is configured to electrically connect the control board and the battery module,

wherein a recessed part is provided at an edge part of the control board,

wherein the control board and the bus bar module are arranged in a stacked manner, and

wherein connection terminals of the bus bar module which are connected to the battery module are exposed through the recessed part when viewed from the control board,

wherein the bus bar module includes bus bar, which have the connection terminals, and a resin member which supports the bus bars,

wherein the resin member includes an opening, and

wherein each bus bar includes a lead pin that is exposed from the opening and connected to the control board.

2. The power supply control device according to claim 1, wherein the lead pins are bent so that tips thereof face the control board.

3. The power supply control device according to claim 1, wherein each bus bar includes a bent portion that is bent outside the resin member and connected to the connection terminal.
