Abstract

Provided is a substrate for sensing voltage and temperature of battery cells, and more particularly, a substrate for sensing battery cells firmly fixed to the battery cells by a clip coupling method and easily detached and attached therefrom.

First claim

The invention claimed is:

1. A sensing substrate for sensing voltage and temperature of stacked battery cells each having a positive electrode and a negative electrode exposed to one side of the stacked battery cells, the sensing substrate comprising:
a slot formed in a bottom surface of the sensing substrate at a position corresponding to a corresponding positive electrode or a corresponding negative electrode, wherein the slot is open towards the one side of the stacked battery cells, and the corresponding positive electrode and the corresponding negative electrode is inserted into the slot when the sensing substrate is mounted on the stacked battery cells; and
a terminal formed correspondingly to the slot, one end portion of the terminal being fixed to the sensing substrate and the other end portion thereof protruding toward an inner space of the slot, wherein a bottom surface of the other end portion of the terminal is configured to electrically contact with a top end of the corresponding positive electrode or the corresponding negative electrode when the corresponding positive electrode or the corresponding negative electrode is inserted into the slot.

2. The substrate for sensing battery cells of claim 1 , wherein the slot includes a plurality of slots formed so as to be spaced apart from each other at a predetermined distance along a length direction of the sensing substrate and the predetermined distance corresponds to a distance between two adjacent battery cells in the stacked battery cells.

3. The substrate for sensing battery cells of claim 1 , wherein the slot includes:
a first slot formed on one side of the bottom surface of the sensing substrate so as to correspond to the positive electrode,
a second slot formed on the other side of the bottom surface of the sensing substrate so as to correspond to the negative electrode, and
the first slot and the second slot are formed to cross each other.

4. The substrate for sensing battery cells of claim 1 , further comprising a temperature sensor bracket integrally formed with the sensing substrate and extending downwardly from the bottom surface of the sensing substrate.
