Abstract

A pouch battery module is provided. The pouch battery module includes a metal housing, wherein a plurality of pouch battery cells arranged along a first direction is disposed inside the metal housing; and a rigid insulation plate being provided between an outermost pouch battery cell and the metal housing along the first direction.

Claims (29)

1. A pouch battery module, comprising:

a metal housing, wherein a plurality of pouch battery cells arranged along a first direction is disposed inside the metal housing;

a rigid insulation plate, being provided between an outermost pouch battery cell and the metal housing along the first direction; and

a heat insulation cushion provided between each adjacent two of the pouch battery cells, wherein each of the heat insulation cushions are bonded to the pouch battery cells by a structural adhesive,

wherein the rigid insulation plate is provided as two rigid insulation plates, the pouch battery cells are arranged in between the two rigid insulation plates along the first direction, the pouch battery module further comprises two wiring harness plates, and the two wiring harness plates are provided between the two rigid insulation plates and respectively engaged with end portions of the two rigid insulation plates.

2. The pouch battery module according to claim 1 , further comprising: a conductive piece and a high voltage terminal;

the conductive piece and the high voltage terminal both being installed on the wiring harness plate, the conductive piece being configured to electrically connect the adjacent pouch battery cells, the high voltage terminal being electrically connected to the pouch battery cells.

3. The pouch battery module according to claim 2 , further comprising: an end plate and a lead-out support, a through hole for the high voltage terminal to pass through being provided on the lead-out support;
