A lot of people will ask, what does a lithium battery pack mean? What is a battery pack pack? Pack Lithium Battery Pack assembly what are the requirements and so on. The following can save electrical small series to talk to everyone about the lithium battery pack knowledge, are wide open eyes to watch!
One, what is a lithium battery pack? Battery pack generally refers to the combination of batteries, mainly refers to the lithium battery pack processing and assembly, mainly the core, battery protection Board, battery connectors, label paper and other through the battery pack process combination processing into the customer needs of the product. Battery pack is now mainly concentrated in the lithium battery pack factory, are stabbed with their own pack structure design, pack electronic design and pack production workshop, according to customer needs for independent development and design, through the battery program, battery specifications, Battery samples to meet the customer's pack lithium battery customization requirements confirmed, and then let the Pack Workshop pack production line for production and processing, quality inspection qualified after shipment. Second, know lithium battery monomer, lithium battery and lithium battery pack Lithium battery Monomer (cell): the most basic element that makes up the battery pack and the battery pack, and the voltage generally provided is between 3v-4v; Lithium battery Pack (batteries): A collection of multiple monomers that form a single physical module that provides higher voltages and capacities; Lithium battery Pack (Pack): It is generally made up of multiple battery packs, but also added to the Battery Management system (BMS) and so on, that is, the battery factory finally provided to the user's products. That's what everyone often says about lithium batteries. Third, the battery pack composition Pack includes battery pack, confluence, soft connection, protection Board, outer packaging, output (including connectors), barley paper, plastic bracket and other auxiliary materials together to form a pack.
Four, the production process of lithium battery pack Five, characteristics of lithium battery pack Has the complete function, can be applied directly; Variety of types, the same application needs to be implemented in a number of packs. Lithium battery pack packs require a high degree of consistency in the battery (capacity, internal resistance, voltage, discharge curve, life). The cycle life of the lithium battery pack pack is lower than the cycle life of a single battery. Use under limited conditions (including charging, discharge current, charging mode, temperature, humidity condition, vibration condition, degree of stress, etc.) The Lithium Battery Pack Pack Protection Board requires a charging equalization function. High voltage, large current battery pack (such as electric vehicle battery, energy storage system) requirements equipped with battery management system (BMS), can, RS485 and other communication bus. Lithium battery pack pack on the charger requirements are high, some requirements and BMS to achieve communication, the purpose is to make each battery work properly, fully play out the energy stored in the battery, and ensure that the use of safe and reliable.
Six, lithium battery pack process Lithium battery pack is achieved in two ways, one is through laser welding or ultrasonic welding or pulse welding, which is a common welding method, the advantage is better reliability, but not easy to replace. Second, through the contact of elastic metal sheet, the advantage is that there is no need for welding, battery replacement is easy, the disadvantage is that it may lead to poor contact. Well, the above is the basic knowledge of lithium battery pack pack, in fact, battery pack pack There is still a lot of need for you to understand, lithium battery demand is increasing, many lead-acid battery enterprises have also introduced lithium-ion products, battery pack pack enterprises want to develop, it is bound to rely on more than battery production enterprises, |
