[0002] A tiered module energy storage PACK structure refers to assembling multiple battery modules (battery cells) in a specific tiered manner to form a complete energy storage battery PACK (battery pack) system. With the rapid development of the new energy vehicle industry, a large number of power batteries are being phased out after reaching the end of their vehicle lifespan, creating a huge market for tiered utilization. To address issues such as high cost, low efficiency, and time consumption, a tiered module energy storage PACK structure is employed.
[0003] However, integrating tiered modules into energy storage PACK systems presents numerous technical challenges, particularly in heat dissipation. Currently, most energy storage PACK systems on the market employ liquid cooling or natural cooling methods. Liquid cooling systems are expensive and complex to maintain, while natural cooling struggles to meet high-power demands. Furthermore, existing module mounting methods, with separate end plates to accommodate different module structures, are inconvenient to use. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] Reference Figure 1 - Figure 4An embodiment of this utility model is provided: a tiered module energy storage PACK structure, including a PACK structure body 1, a sheet metal structure 2 fixedly connected inside the PACK structure body 1, a fan array structure 3 disposed inside the sheet metal structure 2, multiple air ducts 4 disposed inside the PACK structure body 1, a beam structure 5 fixedly connected inside the PACK structure body 1, a PCB device 6 fixedly connected inside the PACK structure body 1, a power connector 7 disposed inside the PACK structure body 1, and a communication connector 8 disposed inside the PACK structure body 1.
[0020] Specifically, the sheet metal structure 2 is made of high-strength, corrosion-resistant sheet metal. The design of the sheet metal structure 2 can provide good protection for the PACK structure body 1. The fan array structure 3 reserves the installation position of the fans, and multiple fans can be installed according to the actual situation of different power usage requirements. The air duct 4 is optimized to guide the airflow well. By adopting the design of the fan array structure 3 and the optimized air duct 4, it can be ensured that the heat generated by the battery system during operation can be dissipated in a timely and even manner, thereby ensuring the normal operating range of the battery system, extending the battery life and improving the battery stability. Since the PACK structure body 1 has different beam structures 5 inside, it can be adapted to different tiered modules and different beam structures 5. The power connector 7 and communication connector 8 can ensure high reliability and low resistance of electrical connections between modules. The reasonable electrical circuit layout avoids cross interference and short circuit risks.
[0021] Reference Figure 1 The fan array structure 3 has multiple fan installation positions reserved;
[0022] Specifically, the multiple pre-reserved fan mounting locations allow for fan installation according to actual usage needs, maximizing heat dissipation and extending battery life.
[0023] Reference Figure 1 The PACK structure body 1 has multiple beam structures 5 that are adapted to different tiered modules, which are fixedly connected inside.
[0024] Specifically, by adopting a modular design and a customizable module fixing beam structure 5, different battery module structures are adapted to each other, and different battery modules are designed into a single battery module composed of one or more modules according to power demand.
[0025] Reference Figure 4 PCB device 6 can meet the acquisition needs of different modules;
[0026] Specifically, the PCB device 6, designed to adapt to different modules, transmits the collected voltage and temperature signals to the BMU.
[0027] Working Principle: When this PACK structure is required, the main body 1 of the PACK structure is a high-strength, corrosion-resistant sheet metal structure 2. Since the PACK structure 1 has an internal fan array structure 3 with multiple fan installation positions, the number of fans can be increased according to actual needs to meet different power requirements. Optimized air ducts 4 guide airflow. The PACK structure 1 also features a flexible module mounting beam structure 5, which can be adapted to different tiered modules to meet the adaptability requirements of different modules. The PCB device 6, which adapts to the modules, achieves the desired data acquisition effect for different modules and facilitates future maintenance. Automotive-grade connectors: power connector 7 and communication connector 8, ensure high reliability and low resistance in electrical connections between modules. A reasonable electrical circuit layout avoids cross-interference and short-circuit risks. This PACK structure not only allows for the use of the original module fixing method, but also provides high flexibility by fixing the battery modules through different beam structure designs 5. Furthermore, the PCB device 6, which adapts to different modules, satisfies the signal acquisition function of the modules.
