STORAGE BATTERY MODULE
First Claim
1. A storage battery module comprising:
- a plurality of battery cells in which an electrode group including a positive electrode and a negative electrode, and a positive electrode collector plate and a negative electrode collector plate connected to the positive electrode and the negative electrode are accommodated in a battery case, and a positive external terminal and a negative external terminal connected to the positive electrode collector plate and the negative electrode collector plate are provided to be exposed to outside of the battery case;
a circuit board including a wiring for temperature detection having a land and connected to the positive external terminal or the negative external terminal of the battery cell;
a temperature sensor that is thermally bonded to the land of the wiring and detects a temperature of the battery cell; and
a voltage detecting wiring for detecting a voltage of the battery cell connected to the land.
