[0045] In combination Figures 1 to 5 As shown, according to specific embodiments of the present application, a modular integrated battery box and a power battery with the same are provided.

[0046] Specifically, the modular integrated battery box comprises a lower shell 1, an upper cover 3 and a front panel module. The lower shell 1 is provided in a flat plate structure; the upper cover 3 is arranged above the lower shell 1, the upper cover 3 is connected with the lower shell 1, and a containing space for containing battery modules 2 is formed between the upper cover 3 and the lower shell 1; and the front panel module is detachably connected with the upper cover 3.

[0047] By applying the technical scheme of the present application, the lower shell 1 in a flat plate structure is adopted, the processing technology of the lower shell 1 is simplified, the mold cost is reduced, and the space utilization is improved. By detachably connecting the front panel module with the upper cover, the installation, debugging, maintenance and repair of the battery box are greatly facilitated, the entire battery box cover does not need to be disassembled, and the maintenance time and cost are reduced. The present application solves the problem that the upper cover needs to be disassembled for maintenance of the front panel in the prior art, resulting in inconvenience in debugging and maintenance.

[0048] It should be further explained that a sealing strip is used for sealing at the connection between the lower shell 1 and the upper cover 3, so as to ensure that the waterproof and dustproof performance of the battery box reaches IP67 level. Correct installation and use of the sealing strip can effectively isolate the influence of the external environment on the battery modules 2 in the battery box, and protect the normal operation of the battery system in harsh environments.

[0049] Specifically, the lower shell 1 comprises an upper flat plate and a lower flat plate. The side of the upper flat plate close to the containing space is used for placing the battery modules 2. The lower flat plate is arranged below the upper flat plate, and a plurality of lower flow channels are arranged on the side of the lower flat plate close to the upper flat plate. The lower flow channels are used for containing cooling liquid, the lower flow channels are formed by stamping process, and the upper flat plate and the lower flat plate are formed by brazing. By designing the lower flow channels on the lower flat plate for containing cooling liquid, heat management can be more effectively performed, the battery modules 2 can be ensured to operate at an optimal temperature, and thus the performance and service life of the battery are improved. In the present embodiment, Al3003 material is used for stamping and brazing process, so that the lower shell 1 has good heat dissipation performance and structural strength, and the manufacturing cost is reduced.

[0050] In an embodiment of the present application, the shape of the lower flow channel can be serpentine, linear, meshed or other forms, and the specific shape depends on the size of the battery box, the cooling requirement and the layout of the liquid cooling plate. The width and depth of the flow channel can be designed according to the requirements to ensure the uniformity of fluid flow while reducing fluid resistance to improve cooling efficiency.

[0051] Optionally, the upper plate and the lower plate are combined by brazing technology, using aluminum-silicon alloy as the filler metal to ensure the strength and sealing of the combined part, further reducing the manufacturing cost.

[0052] Specifically, the side of the upper plate facing the accommodation space is provided with a plurality of mounting beams 7, which are arranged at intervals along the length direction of the lower shell 1, and the mounting beams 7 are used to fix the battery module 2. The design of the mounting beams 7 ensures the stability and safety of the battery module 2 in the box, avoiding displacement or vibration of the battery module 2 during vehicle driving or system operation.

[0053] It should be further explained that the lower shell is a flat plate structure without side walls, and the width and length can be flexibly adjusted. The installation of the battery module 2 is convenient, and the tool activity space is unlimited and safe. The space utilization rate is high, and it can be compatible with different modules. Only the size of the upper plate needs to be adjusted, without the need to open the mold, which is convenient for processing, without the need to change and add other parts, with low cost, high flexibility, strong compatibility, modularization and universality.

[0054] As shown in Figure 2 In the embodiment, two mounting beams 7 are provided, which are connected to the side of the upper plate close to the accommodation space, and the mounting beams 7 are arranged at both ends of the upper plate, and the battery module is fixed on the two mounting beams 7. Among them, the mounting beam 7 can be made of high-strength steel. When the battery box needs to accommodate multiple modules, high-strength steel has excellent load-bearing capacity, which can ensure that the mounting beam 7 remains structurally stable under heavy pressure, avoiding displacement of the mounting position of the battery module 2 due to deformation of the beam, thereby affecting the overall safety and stability of the battery box.

[0055] Further, the front end of the upper cover 3 is provided with a positioning structure, and the front panel module is detachably connected through the positioning structure. The design of the positioning structure makes the installation and disassembly of the front panel module simple and fast, without the need for complex tools. Only by aligning the positioning structure can the installation of the front panel module be easily completed, greatly improving the installation efficiency. The detachable connection between the front panel module and the positioning structure allows the front panel module to be individually disassembled and washed for maintenance, without the need to disassemble the upper cover, improving the maintenance efficiency.

[0056] Specifically, the positioning structures are multiple, and the multiple positioning structures are arranged at intervals along the length direction of the upper cover 3. The arrangement of the multiple positioning structures enables the front panel module to be divided into different modules according to requirements, and each module is detachably connected with the upper cover 3, thereby improving the installation precision and sealing performance of the front panel module, meeting the requirements of waterproof and dustproof level IP67, and further improving the reliability and safety of the battery box.

[0060] Optionally, the first mounting body is the mounting basis of the high-voltage socket 8 and the circuit breaker 9, and the first mounting body is provided with a flange structure around, and a plurality of through holes are arranged on the flange structure. The first mounting body is usually made of corrosion-resistant and high-strength materials such as stainless steel or aluminum alloy to ensure its stability and durability in a high-voltage environment. The first mounting body is usually connected with the upper cover by bolts, which ensures the close fit of the high-voltage panel 4 and the upper cover 3, and facilitates installation and maintenance.

[0061] The circuit breaker 9 is installed on one side of the high-voltage socket 8 and is tightly connected with the first mounting body. The circuit breaker 9 plays a role of overload and short-circuit protection in the circuit. Once an abnormal current condition is detected, the circuit breaker 9 will automatically disconnect the circuit to prevent electrical fire or battery damage. The integrated design of the circuit breaker 9 simplifies the internal wiring of the battery box, reduces the failure points, and improves the overall safety of the system.

[0062] It should be further explained that the high-voltage socket 8 is made of insulating material to prevent electrical short circuit.

The integrated design of the wire harness socket 14 is fixedly connected with the second mounting body close to the accommodation space, compared with the prior art, the fixing bracket of the wire harness socket is reduced, the occupied space is further saved, and the space utilization rate can be further improved.

[0066] The fire interface 13 is fixedly connected with the second mounting body, and is used for connecting a fire extinguishing system, such as a fire extinguishing agent injection pipe or a detection sensor. In an emergency, the fire interface can quickly start the fire extinguishing system to prevent a fire or explosion accident inside the battery box.

[0067] The explosion-proof valve 12 is a pressure release device that automatically opens when the internal pressure of the battery box exceeds a safety threshold (usually due to gas accumulation caused by battery thermal runaway or explosion), releasing the internal pressure and preventing the overall explosion of the battery box, protecting the safety of personnel and equipment.

[0068] The low-voltage socket 11 is used to connect the low-voltage electrical system of the vehicle, such as the instrument panel, control system, etc., to ensure normal communication and control between the battery box and other electrical systems.
