Abstract

A battery wiring module includes: connection members electrically connecting adjacent positive and negative electrodes in an electrode row of a battery assembly; voltage detection lines connecting the connection members and a control unit; and a holding member holding the connection members and the voltage detection lines, and including an electric wire arrangement part in which the voltage detection lines are arranged and which includes electric wire outlets. The batteries are divided into groups so as to correspond to the electric wire outlets, respectively, such that the voltage detection lines belonging to one of the groups are pulled out from the electric wire arrangement part toward the control unit through the corresponding one of the electric wire outlets.

First claim

What is claimed is:

1. A battery wiring module attachable to a battery assembly comprising a plurality of batteries, each of the plurality of batteries comprising a positive electrode and a negative electrode, the battery assembly in which the plurality of batteries are arranged so as to form two electrode rows such that the positive electrode and the negative electrode of adjacent batteries are arranged to be adjacent to each other in each of the electrode rows, said battery wiring module comprising:
a plurality of connection members which are attached to the electrode rows, and which electrically connect adjacent positive electrode and negative electrode in each of the electrode rows;
a plurality of voltage detection lines, each of which comprises a first terminal electrically connected to a corresponding one of the plurality of connection members and a second terminal electrically connected to a control unit for battery voltage monitoring disposed between and along the electrode rows; and
a holding member which holds the plurality of connection members and the plurality of voltage detection lines for each of the electrode rows,
wherein the holding member comprises an electric wire arrangement part in which the plurality of voltage detection lines are arranged and which is formed along the electrode rows,
wherein the electric wire arrangement part comprises a plurality of electric wire outlets, and
wherein the plurality of batteries are divided into a plurality of groups so as to correspond to the plurality of electric wire outlets, respectively, such that the second terminals of the plurality of voltage detection lines belonging to one of the groups are pulled out through the corresponding one of the electric wire outlets from the electric wire arrangement part toward the control unit.

2. The battery wiring module according to claim 1 ,
wherein the control unit comprises a plurality of electric wire connection parts to which the second terminals of the plurality of voltage detection lines are electrically connected, respectively,
wherein the electric wire arrangement part is formed between each of the electrode rows and the control unit, and
wherein the plurality of electric wire outlets are positioned to oppose the respective electric wire connection parts of the control unit.

3. The battery wiring module according to claim 1 ,
wherein the electric wire arrangement part is formed in a gutter shape comprising a bottom extending along an arrangement direction of the batteries and first and second walls extending upward from the bottom, the first wall being closer to the control unit than the second wall, and
wherein the electric wire outlets are formed by cutting the first wall.

4. The battery wiring module according to claim 3 , wherein the plurality of electric wire outlets are formed at predetermined intervals in the first wall.
