Title:
バッテリパック
Document Type and Number:
Japanese Patent JP7227078
Kind Code:
B2
Abstract:
To minimize a short-circuit current between bus bars even when water enters a case in a battery pack in which a plurality of single cells are housed in the case.SOLUTION: A battery pack 10 includes a first core pack 14 and a second core pack 16 holding a plurality of single cells 30. In the first core pack 14 and the second core pack 16, vertically adjacent cell groups are electrically connected to each other via any of a first cell group communication bus bar 56a to a fourth cell group communication bus bar 56d. The second cell group communication bus bar 56b and the third cell group communication bus bar 56c facing each other are separated by a first shielding wall 40a formed on the first core pack side holder 31a and a second shielding wall 40b formed on a second core pack side holder 31b.SELECTED DRAWING: Figure 3
