      Lithium Battery Processing, Lithium Battery PACK Manufacturer

      2019-07-06

      Lithium-ion batteries are widely used, ranging from civil digital and communication products to industrial equipment and military power supply. Different products require different voltages and capacities. Therefore, there are many applications of lithium-ion batteries in series and parallel. The application batteries formed by adding protective circuits, shells and outputs are called PA. CK. PACK can be a single battery, such as cell phone batteries, digital camera batteries, MP3, MP4 batteries, etc., or a series-parallel combination battery, such as laptop batteries, medical equipment batteries, communication power supply, electric vehicle batteries, standby power supply, etc.






      1. Composition of lithium battery PACK:






      PACK consists of battery pack, protective board, outer package or shell, output (including connector), key switch, power indicator, EVA, barley paper, plastic support and other auxiliary materials. The external characteristics of PACK are determined by its application. There are many kinds of PACK.






      2. Production process of lithium battery PACK:

      3. The Characteristics of Lithium Battery PACK






      It has complete functions and can be applied directly.






      Diversity of species. There are many kinds of PACKs for the same application requirement.






      Battery PACK requires a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life).






      The cycle life of PACK battery pack is lower than that of single battery.






      Use under limited conditions (including charging, discharging current, charging mode, temperature, humidity, vibration, stress level, etc.)






      The PACK protection board of lithium battery pack requires charging equalization function.






      High voltage and high current battery pack PACK (such as electric vehicle battery and energy storage system) requires equipped with battery management system (BMS), CAN, RS485 and other communication buses.






      Battery PACK has high requirements for charger. Some requirements communicate with BMS in order to make each battery work normally, fully exert the energy stored in the battery, and ensure safe and reliable use.






      4. Design of Lithium Battery PACK






      Fully understand the use requirements, such as application environment (temperature, humidity, vibration, salt spray, etc.), use time, charging, discharge mode and electrical parameters, output mode, life requirements, etc.






      Select qualified batteries and protective circuit boards according to operation requirements.






      Meet the requirements of size and weight.






      The packing is reliable and meets the requirements.






      The production process is concise.






      Optimize the scheme.






      Minimize the cost.






      Detection is easy to implement.






      5. Cautions for the use of lithium batteries!!!






      Do not put into fire or close to heat source!!!






      The output positive and negative poles can not be directly connected by metal.






      Do not use beyond the battery temperature range.






      Do not squeeze the battery.






      Use a special charger or charge it in the right way.






      Please recharge the battery every three months when it is on hold. And according to the storage temperature.
