Lithium Battery Assembly PACK Production Process.36 volt golf cart batteries

　　Lithium ion batteries are widely used, ranging from civilian digital and communication products to industrial equipment and military power supplies. Different products require different voltages and capacities, so there are many cases of series and parallel use of lithium-ion batteries. The application battery formed by adding protective circuits, outer shells, and outputs to lithium-ion batteries is called a PACK. PACK can be a single battery, such as a mobile phone battery, digital camera battery, MP3, MP4 battery, etc., or a series parallel combination battery, such as a laptop battery, medical device battery, communication power supply, electric vehicle battery, backup power supply, etc.

　　1. Lithium battery pack composition:

　　PACK consists of battery pack, protective board, outer packaging or casing, output (including connectors), key switch, battery indicator, and auxiliary materials such as EVA, barley paper, plastic bracket, etc., which together form a PACK. The external characteristics of PACK are determined by the application. There are many types of PACKs.

　　2. Production process of lithium battery PACK:

　　3. Characteristics of Lithium Battery PACK

　　Diversity of species. Multiple PACKs can be implemented for the same application requirement.

　　The battery pack PACK requires a high degree of consistency in the battery (capacity, internal resistance, voltage, discharge curve, lifespan).

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

　　Used under limited conditions (including charging and discharging currents, charging methods, temperature and humidity conditions, vibration conditions, stress levels, etc.)

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

　　High voltage and high current battery packs (such as electric vehicle batteries and energy storage systems) require the installation of a Battery Management System (BMS), CAN, RS485, and other communication buses.

　　The battery pack PACK has high requirements for chargers, and some requirements are communicated with BMS to ensure that each battery operates normally, fully utilizes the energy stored by the battery, and ensures safe and reliable use.
