Title:
BATTERY MODULE AND BATTERY PACK USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/014398
Kind Code:
A1
Abstract:
Disclosed is a battery module in which a plurality of batteries are arranged and stored inside a housing. Each battery, in an electrode part thereof, has an open part through which a gas generated inside said battery is discharged outside the battery. A separating plate provided in contact with the cases of the batteries, around the electrode parts of the batteries, partitions the housing into: a storage section which stores the plurality of batteries and a cooling fluid or cooling agent which fills the gaps between the plurality of batteries; and a discharge chamber through which the gas discharged from the open parts in the electrode parts is discharged outside the housing. The open parts in the electrode parts connect to the discharge chamber via through-holes formed in the separating plate. This configuration allows a parallel connection and, while keeping the temperatures of the plurality of batteries uniform, allows efficient temperature regulation with respect to heat generation due to factors such as the batteries being short-circuited.
