Do you know the reasons for the design of lithium-ion battery packs?

1. Explosion-proof: Once the lithium-ion battery pack becomes thermally out of control, the air pressure in the battery pack increases sharply. At this time, the battery pack is in danger of explosion, so the PUW explosion-proof valve becomes a breaking port, which can quickly release the pressure in real time. 2. Maintain the air pressure balance between the surface and the inside of the lithium ion battery pack: Because the temperature of the battery pack changes during the charging and discharging process, the air pressure inside the battery pack changes, and the PUW explosion-proof valve can be breathable while not leaking, so it can be maintained The air pressure in the bag always communicates with the outside world. 3. Consider the design of the PACK management system for lithium-ion battery packs: consider overshoot, overdischarge, overtemperature, detection accuracy, battery balance, etc. To ensure that the battery is safe and reliable, it must be designed with fairness and verified by the market. 4. Consider the machine layout design of energy storage lithium-ion battery packs: consider strength, shock resistance, heat dissipation/heating, waterproof, dustproof, etc.; consider electrical design, consider safety regulations, EMC safety regulations and other factors. 5. The layout of the lithium-ion battery pack is waterproof and anti-vibration: After the lithium battery is soaked, the positive and negative electrodes are short-circuited, and continuous discharge will cause damage to the internal layout of the battery. When designing the battery pack, consider the waterproof and dustproof function. 6. The influence of temperature on the layout of lithium-ion batteries: thermal factors affect the layout design of battery packs. Lithium-ion battery energy storage battery packs are sensitive to temperature conditions. If the temperature is too high, it will seriously affect the charging and discharging performance of the battery. Many characteristic parameters, such as internal resistance, voltage, SOC, usable capacity, charge and discharge efficiency, and battery life. 7. Material selection for the layout of lithium-ion battery packs: high-voltage-resistant insulation is one of the most important technical requirements for battery pack layout design. The battery pack layout contains various types of lithium-ion batteries. After the batteries are assembled, the total voltage and total current will be very large. The plastic has good and high-voltage insulation. Generally, nylon with high recyclability and plasticity can be used as raw material. Adding 5% to 45% of glass fiber to the material, GF reinforcement can improve the layout strength and vibration resistance.
