Description

Technical Field

[0001] The present invention relates to the technical field of charging and discharging jigs, and particularly to an integrated pressurized heating water-cooled charging and discharging test device for a double-output tab soft-pack battery. Background Art

[0002] In recent years, with the gradual popularization of electric vehicles, the technical requirements for rapid replacement, rapid charging, battery safety, etc. of electric vehicle batteries have gradually increased. Currently, the common part of electric vehicle batteries is completely placed in an independent storage space, and a temperature monitoring is carried out by using an induction sensing module. Such a structural design still has great deficiencies. For example, the heat dissipation performance is not good. Although the temperature can be effectively monitored, the heat dissipation performance cannot be fundamentally improved to reduce the safety hazards. During the automated production process of soft-pack batteries, since the jig should also change according to the length of the battery after the model change, in order to more conveniently position the battery without replacing the jig, it is necessary to position the battery from its length and width respectively and be able to extend into the jig channel. However, the existing equipment cannot position the length and width of the battery, resulting in poor adaptability of the equipment, low formation efficiency, and low efficiency of the water-cooling system.

At the same time, it can also be compatible with pressurizing and heating the soft-pack battery. It is widely used in multi-scenario application occasions of laboratories and research institutes. The operation is simple, reliable and safe. The device has a small floor area, high integration, and low cost. Multiple sets of jig devices arranged together can form a pressurized water-cooling system with multiple storage modules, and the market application scenario is broad.
