Features and precautions of lithium battery PACK

The production of lithium battery PACK is a combination of individual batteries through welding or other methods, and customized products according to the relevant parameters of the equipment to be mounted. According to the use, it can be divided into power lithium battery pack, energy storage battery pack, and special lithium battery pack. . 1. Lithium battery PACK composition: PACK includes lithium battery pack, protection board BMS, outer packaging or shell (plastic or metal), output (including connector), key switch, power indicator, and EVA, barley paper, plastic bracket, etc. These items of materials together make up PACK. The external characteristics of PACK are determined by the application. There are many types of PACK. According to the needs, select the appropriate combination of accessories to add functions to the finished lithium battery, such as whether it is necessary to display power and have a communication port. 2. The purpose of accessories: 3. The characteristics of lithium battery PACK 1. It has complete functions and can be directly applied. 2. Diversity of types. There are a variety of lithium battery PACKs that can achieve the same application requirement. 3. Lithium battery packs require batteries to have a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life). 4. The cycle life of the lithium battery pack PACK is lower than that of a single battery. 5.  Use under limited conditions (including charging, discharging current, charging method, temperature, humidity conditions, vibration, stress level, etc.) 6. Lithium battery pack protection board requires charge equalization function. 7.  High-voltage, high-current battery packs (such as electric vehicle batteries, energy storage systems) require communication buses such as battery management systems (BMS), CAN, RS485, etc. 8.  Lithium battery packs have higher requirements for chargers. There are some requirements to communicate with the BMS, the purpose is to make each battery work normally, fully utilize the energy stored in the battery, and ensure safe and reliable use. 4. Precautions for the use of lithium batteries! ! ! Do not put into fire or use near heat source! ! Do not use metal to connect the positive and negative poles of the output directly. Do not use outside the battery temperature range. Do not squeeze the battery forcefully, handle it gently. Use a dedicated charger or charge it in the correct way. Please charge the battery once every three months when it is shelved, and store it at the storage temperature.
