Abstract

Official abstract text for this publication.

A high voltage battery includes an electrode assembly. A pouch-shaped case is sealed by an edge portion to cover the electrode assembly and has an open inlet formed at one side of the case to allow an electrolyte to be injected to the case therethrough. An outlet is connected to the inlet and discharges gas generated inside the case outside a vehicle.

First claim

Opening claim text (preview).

What is claimed is: 1. A high voltage battery comprising: an electrode assembly; a pouch-shaped case sealed by an edge portion to cover the electrode assembly, and having an open inlet formed at one side of the case to allow an electrolyte to be injected to the case therethrough and sealed after injecting the electrolyte; and an outlet connected to the inlet and for discharging gas generated in the case outside a vehicle: wherein the inlet includes a stress concentration portion formed therein, which easily breaks when the gas is generated inside the case, wherein the stress concentration portion has a notch shape having a tip portion directed toward the electrode assembly. 2. The high voltage battery of claim 1 , wherein the inlet of the case is perpendicular to the electrode assembly. 3. The high voltage battery of claim 1 , wherein one side of the edge portion of the case is wider than the other side and the inlet and the outlet are formed at the wider side. 4. The high voltage battery of claim 1 , wherein the outlet is in parallel to the electrode assembly and an end portion of the outlet is bent by a set length. 5. The high voltage battery of claim 1 , wherein the outlet is in perpendicular with the inlet. 6. The high voltage battery of claim 1 , wherein the outlet is separately formed and is coupled to the inlet of the case.
