Soft package battery cell module of spot welding process

Abstract

The invention discloses a soft package battery cell module of a spot welding process. The soft package battery cell module comprises a bottom frame and connecting rods, and a plurality of heat dissipation frames are fixedly connected into the bottom frame at equal intervals in the horizontal direction. A protection frame is fixedly connected to the top of the bottom frame, a heat conduction plateis fixedly connected to the top of the bottom frame and located in the protection frame, elastic limiting strips are fixedly connected to the positions, close to the two side edges, of the top of theheat conduction plate, and first buffer frames are fixedly connected to the four corners in the protection frame. In the present invention, by the connecting rods, the spacing distance between heat-conducting partition plates can be effectively adjusted in a sliding manner; the structure of the soft package battery cell module can be effectively adjusted according to the actual structural size ofbattery cells; therefore, the soft package battery cell module can effectively store different types of battery cells, and by adding and moving a first connecting block and a second connecting block,the first connecting block and the second connecting block can drive a barrier plate to effectively perform equal-distance separation between smaller battery cells under the limitation of the moving positions of a rotating shaft and a sliding block.

Description

technical field [0001] The invention belongs to the technical field of battery equipment, and in particular relates to a soft-pack battery cell module with a spot welding process. Background technique [0002] A cell usually refers to a single electrochemical cell containing positive and negative electrodes. It is generally not used directly. It is different from a battery that contains a protective circuit and a casing and can be used directly. However, in the prior art, the pouch cell module is to ensure its actual structure is stable The location of the batteries is directly fixed and limited, so that the equipment cannot effectively increase or decrease the number of batteries inside the battery module according to the actual usage, and at the same time, it is impossible to replace the batteries with different structural volumes, so that the actual use of the equipment is not good. , and when a collision accident occurs, the existing battery cell module cannot effectivel...

[0002] A cell usually refers to a single electrochemical cell containing positive and negative electrodes. It is generally not used directly. It is different from a battery that contains a protective circuit and a casing and can be used directly. However, in the prior art, the pouch cell module is to ensure its actual structure is stable The location of the batteries is directly fixed and limited, so that the equipment cannot effectively increase or decrease the number of batteries inside the battery module according to the actual usage, and at the same time, it is impossible to replace the batteries with different structural volumes, so that the actual use of the equipment is not good. , and when a collision accident occurs, the existing battery cell module cannot effectively resist the impact of the outside world, making its internal battery cells susceptible to rupture and spontaneous combustion under excessive pressure, thereby causing a greater safety hazard in the battery cell module. Effectively protect the internal cells. Most of the existing cell modules adopt a sealed protective structure, so that the heat generated by the internal cells cannot be effectively dissipated, which in turn makes the internal structure of the cells easy to age and shortens the actual service life of the cells.
