Abstract

A battery system capable of cooling overheated battery packs among a plurality battery packs each mounted in a battery case by measuring temperatures of the battery packs is disclosed, and a driving method thereof is provided. In one embodiment, the battery system includes a plurality of battery packs, an air compressor for supplying a compressed cooling air to the plurality of battery packs, a gas dividing unit coupled between the plurality of battery packs and the air compressor and including a plurality of valves, and a controller for controlling opening and closing of each of the plurality of valves according to temperatures of the plurality of battery packs.

First claim

What is claimed is:

1 . A driving method of a battery system comprising:
measuring temperatures of a plurality of battery packs; comparing the measured temperatures of the plurality of battery packs with a first reference temperature; determining whether there is an overheated battery pack among the battery packs; and cooling the overheated battery pack.

2 . The driving method of claim 1 , wherein the cooling of the overheated battery pack comprises opening a valve of an air compressor for providing a cooling air to the overheated battery pack.

3 . The driving method of claim 1 , wherein the cooling of the overheated battery pack comprises opening a valve of a gas dividing unit corresponding to the overheated battery pack.

4 . The driving method of claim 1 , wherein the comparing of the battery pack temperatures with the first reference temperature comprises setting a second reference temperature higher than the first reference temperature.

5 . The driving method of claim 4 , wherein when at least one of the temperatures of the battery packs is higher than the second reference temperature, the cooling of the overheated battery pack comprises opening a valve of an extinguishing unit.

6 . A driving method of a battery system comprising:
detecting a gas leakage from a plurality of battery packs; notifying a controller of a battery pack that leaks a gas among the plurality of battery packs; and releasing the gas from the battery pack leaking the gas to the outside.

7 . The driving method of claim 6 , wherein the releasing of the gas comprises opening a valve of an air compressor coupled to the battery pack.
