Lithium battery PACK is a term that we can often see. So what does PACK mean and what are its key points?

　　Lithium battery PACK generally refers to the assembly process in which a certain voltage and capacity are formed through series and parallel connection of single lithium batteries, and PCM or BMS is added.

　　PACK is the key to the production of lithium battery packs. Many requirements must be considered, such as strength, earthquake resistance, heat dissipation, heating, waterproof, dustproof, etc., as well as electrical design, safety requirements, and intelligent management system requirements.

　　1. Choose a good PCM or BMS according to the real needs of customers and actual application scenarios. This is the most critical step.

　　2. Pay attention to the battery connection method and method, because the accuracy of the BMS measurement, the true impedance distribution and other issues must be taken into consideration.

　　3. The PACK process must consider the actual needs of customers to carry out the overall external waterproof and seismic design.

　　4. PACK internal insulation design, the insulation conditions must be set separately to meet the impact, vibration, humidity and other complex environments, the battery is still safe and effective.

　　The above is about the basic knowledge of PACK and several major factors that affect the design of lithium battery PACK.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect substitute for lead-acid batteries, and are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data centers and other industries.
