The difference between power battery PACK structure design and energy storage PACK structure design

The < power battery >PACK structure design and < energy storage >PACK structure design are similar in some aspects, but there are also many differences. Because both involve the overall layout of the battery system, electrical connection, thermal management, safety protection and other aspects of the design. However, there are some differences between them as follows.

1, the power battery PACK usually refers to the battery system that provides power for the car, while the energy storage PACK is more applied to stationary energy storage systems, such as wind power and solar power energy storage system. Therefore, the application scenarios and performance requirements of the two are different.

2, the power battery PACK needs to meet the high dynamic performance requirements of the car, including fast charging, high energy density, long life and so on. The energy storage PACK pays more attention to the stability and economy of the system, as well as the ability to run for a long time.

3, in terms of structural design, the power battery PACK usually needs to consider more mechanical strength and vibration resistance to cope with a variety of complex conditions during the car driving. The energy storage PACK may pay more attention to the heat dissipation and ventilation design to ensure the stability and reliability of the system during long-term operation.

4, the power battery PACK and the energy storage PACK may also be different in terms of material selection, manufacturing process, battery management system, etc. 

What are the specific differences between the "Energy Storage" PACK structure design and "Power Battery" PACK? 

1, the cell used is different: but this structure has no effect

2, the design requirements are different: the power battery pack has higher requirements for waterproof heat dissipation than the energy storage battery pack

3. Different structural fixing: the structural fixing methods of power battery pack and energy storage battery are very different

4, different testing and detection: two different industry battery packs, testing and detection are very different

5, the lifepo4 battery pack structure is different: the power battery pack is generally a CTP structure, and the energy storage battery is a CTM structure

6, the total capacity of the battery PACK is different: the power battery bubble is generally <100kWh, and the industrial and commercial storage is between 200-5000kWh, which has an impact on the structure of the power battery PACK and the energy storage pack in the structural design of the main difference is its application scenario, functional requirements and cost composition. The power battery PACK is more focused on providing efficient and safe power for mobile devices, while the energy storage PACK is more focused on achieving stationary storage and efficient use of energy. 

The question comes, then do the power battery pack structure engineer can directly engage in the work of energy storage structure design? Is the same true vice versa? 

The answer is no, but for one thing, it is very easy to go through the structure of one and then switch to the other structure, because there is a lot of knowledge that is connected, and it can be said that there is 50% of the foundation
