Description

Technical Field

[0001] This utility model belongs to the field of battery structure technology, and in particular relates to an integrated battery structure. Background Technology

[0002] With the rapid development of new energy vehicles, energy storage systems, and portable electronic devices, secondary batteries such as lithium-ion batteries have become the mainstream choice due to their advantages such as high energy density and long cycle life. However, existing technologies mostly use battery stacking to combine batteries, and multiple battery modules are directly installed as a whole. Traditional battery modules have fixed capacities and are mostly connected in series and parallel, so connecting several battery modules requires multiple connectors.

[0003] Overall, using battery stacking to combine batteries leads to an increase in battery structure size and weight, reduces the suitable application scenarios, increases the difficulty of handling, and consequently increases the overall cost. It is also not convenient to remove and put in batteries. Moreover, the battery module combination method is relatively simple and cannot be flexibly expanded. It is prone to complex equalization control, difficult thermal management, and circuit failure due to multiple connectors. Utility Model Content

However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0028] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0029] This embodiment provides an integrated battery structure that integrates battery modules, thereby reducing the size and weight of the battery structure, expanding its suitable application scenarios, reducing the difficulty of handling, and thus lowering the overall cost of the battery structure.

[0030] Combination Figures 1 to 5 As shown, the integrated battery structure of this embodiment includes a housing 10, a battery compartment 20, a control unit 30, and a partition block 40. The battery compartment 20, the control unit 30, and the partition block 40 are all disposed inside the housing 10. The battery compartment 20 and the control unit 30 are integrated, and the battery compartment 20 is separated by the partition block 40.

[0031] In this embodiment, the battery compartment 20 is installed inside the housing 10. Several isolation plates 21 are provided inside the battery compartment 20 to separate and install several battery modules in the battery compartment 20. The battery modules are evenly arranged in the battery compartment 20, and adjacent battery modules are connected in series. This embodiment uses multiple battery modules to work together. The battery modules are isolated by multiple isolation plates 21 and integrated module processing is adopted, which can effectively reduce the connection lines 81 between modules and reduce the failure rate.

[0032] Furthermore, in this embodiment, the battery compartment 20 is provided with an operating handle 60 at one end to pull the battery compartment 20. When it is necessary to replace the battery module, the battery compartment 20 is taken out from the housing 10 by operating the handle 60 so that the battery module inside the battery compartment 20 can be replaced.

[0033] Combination Figure 2 and Figure 3 As shown, the housing 10 of this embodiment is provided with a charging and discharging interface 50. The battery module is charged and discharged through the charging and discharging interface 50. When it is necessary to charge and discharge the battery module, it is used through the charging and discharging interface 50. In this embodiment, there are three partition blocks 40 to block the battery compartment 20 on three sides. While blocking the battery compartment 20, it is convenient to remove the battery compartment 20 from the housing 10.

[0034] In this embodiment, a cooling fan 70 is provided inside the housing 10 to dissipate heat from inside the housing 10.

The control unit 30 includes a BMS management module 31, a VCU module 32, and a GCU module 33. The BMS management module 31 (battery management module), the VCU module 32 (vehicle controller module), and the GCU module 33 (generator controller module) are connected to the battery module. With the cooperation of the BMS management module 31, the VCU module 32, and the GCU module 33, stable control of the battery module is achieved.

[0036] In this embodiment, a connecting box cover 80 is provided inside the housing 10. The connecting box cover 80 covers the VCU module 32 and the GCU module 33. The connecting box cover 80 is provided with a connecting wire 81 and a wire connector 82 to connect the VCU module 32 and the GCU module 33 to the outside. The connecting box cover 80 can reinforce the installation of the VCU module 32 and the GCU module 33, and the connecting wire 81 and the wire connector 82 on the connecting box cover 80 can connect the VCU module 32 and the GCU module 33 to the outside so that the VCU module 32 and the GCU module 33 can be used.

[0037] In practical use, the integrated battery structure of this embodiment integrates the battery modules, reducing the size and weight of the battery structure, expanding its applicable scenarios, and simplifying transportation, thereby lowering the overall cost of the battery structure. Furthermore, the battery modules in this embodiment are easy to handle, and the battery module combination methods are more diverse, allowing for flexible expansion. In addition, this battery structure has a BMS management module 31, which reduces the likelihood of complex equalization control and difficult thermal management. This battery structure adopts integrated modular design with fewer connectors, making it less prone to circuit failures.
