Battery module heating device and battery module heating shape-maintaining monitoring system

Abstract

The invention discloses a battery module heating device and a battery module heating shape-maintaining monitoring system. The battery module heating device comprises a supporting base, a bottom heating assembly, a module supporting assembly and a side heating assembly. The bottom heating assembly comprises a bottom heating plate which is arranged on the supporting base in an up-down moving manner. The module supporting assembly comprises module supporting blocks symmetrically arranged at the two sides of the bottom heating assembly. The side heating assembly comprises heating side plates symmetrically arranged at the two sides of the module supporting assembly, airflow channels are formed in the heating side plates in the length direction of the bottom heating assembly, and air outlets communicating with the airflow channels are formed in heat conduction type soft bonding material pieces on the inner side faces of the heating side plates. Air inlets of the airflow channels communicate with an air source through air inlet channels. By arranging pressure measuring elements in the air inlet channels, the air pressure in the airflow channels can be effectively monitored during heating, and whether a battery module is heated uniformly or not is monitored, so that the heating and curing quality is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of battery module heating, in particular to a battery module heating device and a battery module heating type maintenance monitoring system. Background technique [0002] In the field of new energy power battery modules, the battery cell and the side plate are mainly bonded by glue to meet the structural requirements. During the execution of this process, due to the slow curing of the glue and its vulnerability to external influences, the strength of the assembly structure of the module will be reduced. There are often non-compliance issues. For example: after the side plate and the end plate are welded, because the glue is not cured, the side plate will bulge outward, which will reduce the bonding strength between the side plate and the battery core, and then the impact of the module during use may cause The falling of the battery cell, on the other hand, the gravity of the battery cell may also cause the ...

Problems solved by technology

[0004] However, during the heating process, since it is impossible to effectively monitor whether the heating side plate is completely clamped to the side of the battery module, it is impossible to ensure that the battery module is evenly heated.

In addition, there are ribs on the side of some battery modules, and the corresponding heating side plate needs to be cut to avoid these ribs, which will cause the heat conduction material on the heating side plate to fall off due to the small contact area. It is easy to cause the heating side plate and the battery module to be not tightly bonded, which will lead to unqualified heating and curing
