Abstract
Official abstract text for this publication.
A battery wiring module is attached to a cell group including an arrangement of a plurality of cells having positive pole and negative pole electrode terminals. The battery wiring module is provided with: a plurality of connection members connecting the positive pole and negative pole electrode terminals of adjacent cells of the plurality of cells; and a flexible printed board including a plurality of voltage sensing wires for sensing voltages of the plurality of cells via the plurality of connection members. Each of the voltage sensing wires has an electric current limiting element provided somewhere therealong to limit a flow of overcurrent in the voltage sensing wires. The electric current limiting element is connected to the voltage sensing wires at a portion which is overcoated with an insulating resin.
