Description

Technical Field

[0001] The utility model relates to the technical field of energy storage devices, in particular to a stacked battery cabinet compatible with US and European standards. Background Art

[0002] With the development of new energy technologies, the form of energy application has changed. The domestic market is highly competitive. New energy is gradually replacing the fuel market, and the domestic market application has become relatively mature. However, the foreign market is still lacking, and the application of new energy is relatively scarce.

[0003] Conventional stacked battery cabinets are only suitable for charging with one standard, and a new battery cabinet needs to be customized for other standards, which cannot be universal and has poor applicability. Since the number of battery cells in each layer is large and the number of cables is also large, the wiring is complex and easy to be connected wrongly. To address such problems, a stacked battery cabinet compatible with US and European standards is proposed. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a stacked battery cabinet compatible with US and European standards, which is convenient for realizing the switching use of the two standards and has high universality.

Connection components are provided between the high-voltage box and the battery boxes, between adjacent battery boxes, and between the battery boxes and the base. A first cavity and a second cavity are arranged in parallel in the high-voltage box. A US standard gun seat and a European standard gun seat respectively connected to the first cavity and the second cavity are arranged on the front side of the high-voltage box. A first interface group and a second interface group are respectively arranged on the rear side of the high-voltage box corresponding to the first cavity and the second cavity. A third interface group is arranged on the rear side of the battery box. The compatibility and use of US and European standards are realized by electrically connecting the third interface group with the first interface group or the second interface group.

[0006] As can be seen from the above solution, the battery box is used for energy storage. The high-voltage box is provided with an electrically isolated first cavity and second cavity through a partition. Either of them is connected to the battery box to realize the switching use of the battery cabinet. The US standard gun seat and the European standard gun seat are used for charging compatible with the two standards to meet the needs of different standards. Adjacent battery boxes are stacked and connected through the fixing block and the positioning pin, which is convenient for disassembly, assembly and transportation.

[0007] The battery box includes a battery box body and a battery box cover provided at the end of the battery box body. Inside the battery box body, a number of battery modules are provided through fixed end plates. The battery modules are formed by connecting a number of battery cell monomers. Soft copper bars are provided on the battery modules, and the battery modules are electrically connected to an electrical board through the soft copper bars. Thus, the soft copper bars are used to achieve conductive series connection between the battery modules, and the soft copper bars are used to increase the overcurrent and have the effect of anti-vibration.

[0008] Two groups of protection modules are provided at the rear side of the high-voltage box. The protection modules include a circuit breaker, an air switch, a discharge port, and a debugging port.
