The core problem of custom lithium battery pack of the 12V lithium battery pack is the consistency of the lithium cell, that is, the smaller the value of the difference in pressure, capacity and internal resistance of each cell, the better, so that the assembled 12V lithium battery pack can play the best effect in terms of use efficiency and service life. The following is about how to assemble the 12V lithium battery some technical knowledge to share, I hope to help you.
I. custom battery pack of large capacity 12V lithium battery
Large capacity lithium battery design principle is 12 V will be more than 3.7 V lithium batteries assembly process design and become, in the production of large capacity 12 V lithium battery assembly requirements must be parallel assembly, only the parallel assembly after the big capacity of 3.7 V lithium ion battery to the battery capacity is the largest, and then through the more the number of batteries series parallel assembly of battery capacity is larger.
2. cylindrical 12V lithium battery assembly method
After the series and parallel design of a number of cylindrical cells to form the corresponding 12V lithium battery pack, but one point must be to meet the customer’s battery size, voltage capacity, over-current requirements of the cylindrical 12V lithium battery assembly qualified.
Cylindrical 12V lithium battery assembly such as 12V solar insect lamp lithium ion battery capacity is 2.6AH, nominal voltage is 11.1V, most of the industry will be this 3 series lithium ion battery is called 12V lithium ion battery pack, battery capacity can be customized, such as made 12V10Ah solar insect lamp lithium ion battery, 12V8Ah solar insect lamp lithium ion battery, 12V15Ah lithium ion battery custom technology method, the solar insect lamp battery in this paper uses three 3.7VLC18650 lithium cell PACK assembly, the capacity of the single battery reaches 2600mAh, this kind of insect lamp battery is sometimes called 11.1V lithium ion battery PACK, And the finished product of the small solar insect killing lamp battery pack.
3. custom battery pack of 12V lithium iron phosphate battery
This kind of lithium iron phosphate material customized lithium ion battery pack nominal voltage is generally known as 12.8V, some battery technicians called 12.8V lithium ion battery pack, of course, lithium iron phosphate 12V lithium ion battery customization technology requirements are more stringent, it uses 4 string battery structure, can 26650 lithium ion battery, Or 18650 lithium ion battery PACK customization through 4 series technology PACK processing assembly, and then made into lithium iron phosphate 12V lithium ion battery customized products.
The assembly process of 12V lithium battery is customized according to the actual product demand. The battery customization process is important. After evaluation and analysis based on the actual situation, cost analysis and profit analysis are conducted according to the company’s process to make a comprehensive quotation.
1, understand the real needs of the product, just supply lithium ion battery size, electrical performance requirements, output requirements, functional requirements that can be customized battery.
2. If you do not know the real requirements of the product, you should tell us the functional requirements, working time, product power, appearance shape, etc.
