AI Technical Summary

Technical Problem

Existing electric battery packs face issues with high weight, manufacturing complexity, increased costs, and reduced reliability due to the use of metallic supply channels and welds/gaskets in the thermoregulating liquid distribution system, particularly problematic in electric or hybrid vehicle applications.

Method used

A thermoregulating liquid distribution system integrated into a lower cell-supporting structure, comprising a supply channel and transverse channels defined by overlapping upper and lower plates, eliminating the need for welds and gaskets, and featuring narrow passages to control liquid flow.

Benefits of technology

This design simplifies manufacturing, reduces weight and production costs, enhances reliability, and ensures efficient thermoregulation of battery cells by integrating the distribution system into the support structure, thereby improving overall battery pack performance and safety.

Abstract

An electric battery pack (1), comprising a container (2) with a plurality of battery cells (4) mutually spaced apart and in direct contact with a flow of a thermoregulating liquid. The thermoregulating liquid distribution system includes a supply channel (6) and a plurality of transverse channels (7) below the battery cells (4). Each transverse channel (7) communicates with gaps between the battery cells (4) by means of a plurality of relatively narrow passages (9). The container (2) includes a lower support structure (5) on which the battery cells (4) are rested. The lower support structure (5) comprises a lower plate (5D) and an upper plate (5U) having a plurality of holes defining the relatively narrow passages (9). The upper plate (5U) and the lower plate (5D) are arranged overlapping and rigidly connected to each other along their perimeter, and are configured so as to define between them both the supply channel (6), with its inlet (6S), and the transverse channels (7).
