5000 Cycle Life 12V 25AH Rechargeable Battery Pack With Bluetooth Function

With the rapid development of electric vehicles, energy storage systems and other fields, lithium batteries are the main source of power and energy storage, and their safety and reliability have attracted much attention. Among them, the structural design of the lithium battery pack frame, including the battery cell, battery pack and safety system, is very important to ensure the safety and reliability of the lithium battery. This article will explore the frame structure design of modern lithium battery packs from these three aspects.

1. Cell design

The battery cell is the core component of the lithium battery pack, and its design is directly related to the performance, life and safety of the battery. In the design of battery cells, the following aspects need to be considered:

1) Cell material selection: select high-quality positive and negative electrode materials to ensure that the battery cell has high energy density and cycle life.

2) Sealing design: ensure the tightness of the cell, prevent electrolyte leakage, and reduce potential safety hazards.

3) Heat dissipation design: Through reasonable heat dissipation design, the working temperature of the battery cell can be reduced and the battery life can be prolonged.

4) Cost and volume control: On the premise of ensuring performance and safety, try to reduce the cost and volume of battery cells and improve energy density.

Second, the design of the battery pack

The battery pack is composed of multiple battery cells, and its design needs to consider factors such as the arrangement of the cells, the connection method, and the heat dissipation system to ensure the safe and reliable operation of the entire battery pack.

1) Cell arrangement: A reasonable cell arrangement can make full use of the space and improve the energy density of the battery pack.

2) Connection: Reliable cell connection is adopted to ensure the stable internal connection of the battery pack and reduce the potential safety hazards caused by connection failure.

3) Heat dissipation system: Design an effective battery pack heat dissipation system to reduce the working temperature of the battery pack and prolong the battery life.

4) Battery management system (BMS): integrated battery management system to monitor and manage the battery pack in real time to ensure the safety and reliability of the battery pack.
