AI Technical Summary

Technical Problem

Existing battery module containers are prone to water seepage and condensation problems under adverse weather conditions, resulting in an increase in internal humidity and increasing the risk of arc discharge. At the same time, there are difficulties in handling battery modules, which affects the efficiency of the container.

Method used

A battery module container is designed, with the upper surface of the base plate extending along the lower edge of the door, forming a step that faces the closed position of the door, forming a water receiving volume to collect possible incoming water and prevent water from seeping into the base plate.

Benefits of technology

It effectively prevents water infiltration and condensation, reduces the risk of internal humidity and arc discharge, and makes the handling of battery modules easier and improves the efficiency of container use.

Abstract

The invention relates to a battery module container (16) having a structure (30) comprising:-a bottom plate support (34) having two longitudinal members (60), each having an upper surface (62), and a cross member (64) connecting them,-a bottom plate (32), each having a lower surface (62), the invention relates to a module (10) comprising:-a base plate (20) having an upper surface (43) for supporting said module and extending upwardly to a transverse edge (45) facing said longitudinal member,-peripheral walls, at least one of which defines a door (92A) movable between a closed position in which a lower edge (104) faces said upper surface and an open position, and-a top located above the peripheral walls. Along the lower edge of the door in the closed position, the side edges of the upper surface extend to a height higher than the height of the upper surface, and the floor support defines a step (84) between the face and the upper surface, thereby defining a water receiving volume (108).
