Three types of 12V lithium battery assembly knowledge

As a high-tech enterprise specializing in lithium battery research and development at home and abroad, Mottcell New Energy will explain the assembly methods and knowledge of commonly used 12v lithium batteries.

1. 12V polymer lithium battery assembly

The assembly of 12V polymer lithium battery is more and more simple. The basic principle of 12V polymer lithium battery assembly is to connect polymer lithium batteries in 3 series, but the battery protection board must be added when the polymer 12V lithium ion battery is customized for connection. , Next, according to the laser welding technology, the battery soldering technology, and the PACK lithium-ion battery finished product production and processing technology, the crystallization is mixed, but for the cylinder, the polymer 12V lithium-ion battery is customized through a phase similar to these methods. relatively rare.

The 12V lithium battery assembly workflow is customized according to the actual product needs. The battery customization workflow is important to carry out evaluation and analysis based on the actual situation, and then carry out cost analysis according to the company's process, and comprehensive quotation for profit analysis. Under normal circumstances, the battery is customized the workflow is divided into two parts, as follows:

1. Understand the actual needs of the company's products, and only need to supply the external dimensions of the lithium-ion battery, the electrical performance requirements, the output requirements, and the functional requirements to customize the battery.

2. If you don't know the actual needs of the enterprise products, you can tell us the requirements for the functions to be realized, the working hours, the power of the enterprise products, and the appearance and shape.

2. Cylindrical 12V lithium battery

It is to carry out a series-parallel design of multiple cylindrical cells to form a corresponding 12V lithium battery pack, but one thing must meet the customer's battery size, voltage capacity, and overcurrent requirements to be considered a cylindrical 12V lithium battery. The assembly is qualified.

Cylindrical lithium battery assembly for example, a 12V solar insecticidal lamp lithium-ion battery has a capacity of 2.6Ah and a nominal voltage of 11.1V. Most of the manufacturing industries refer to these 3-series lithium-ion batteries as a 12V lithium-ion battery pack. It can be customized, such as 12V10Ah solar insecticidal lamp lithium ion battery, 12V8Ah solar insecticidal lamp lithium ion battery, 12V15Ah lithium ion battery customized technical method, Mottcell battery solar insecticidal lamp battery passes 3 3.7VLC18650 lithium batteries Carrying out the PACK assembly, the capacity of a single battery is 2600mAh, similar to these insecticidal lamp batteries are sometimes called 11.1V lithium-ion battery packs, and the finished small solar insecticidal lamp battery packs.

3. 12V lithium iron phosphate battery assembly

The nominal voltage of custom-made lithium-ion battery packs similar to these lithium iron phosphate materials is generally called 12.8V, and some battery technicians call them 12.8V lithium-ion battery packs, but the technical requirements for custom-made lithium iron phosphate 12V lithium-ion batteries are becoming more and more rigorous. , it can make 26650 lithium-ion batteries, or 18650 lithium-ion battery packs customized according to the 4-series technology to carry out PACK production, processing and assembly, and then make lithium iron phosphate 12V lithium-ion battery customized enterprise products.
