There are two key ways to assemble lithium batteries, one is production and assembly at the level of lithium battery manufacturers, and the other is to purchase lithium batteries for DIY assembly. In fact, manufacturers have a lot of mechanical automation and programmatic trading practices at the level of lithium battery assembly. As everyone knows, the key to the following is to talk about the DIY method and common problems of lithium battery assembly.
The way to assemble lithium batteries.
In order to better carry out the assembly of our own lithium batteries, we must prepare special tools and rechargeable batteries in advance, and design a plan for the volume, working voltage, and charging and discharging current.
Lithium battery installation process and standards:
Measure and calculate the battery performance you need.
Calculate the working voltage of the rechargeable battery assembled by itself, how much volume, how much balance charge and discharge current is, what is the larger current, and the working voltage after charging and discharging. In addition, according to the characteristics of the relevant rechargeable battery, select and purchase a suitable battery Protection board.
Preparation of lithium battery assembly tooling in advance.
Spiral knife, scissors, vacuum pressure gauge, ammeter or universal watt-hour meter, welding tools include solder wire, electric flux, etc. That is, considering that the special tools and auxiliary materials that are likely to be used in the lithium battery of their own institutions, there should be more or less.
Model selection of lithium batteries and related accessories.
1. The selection of lithium battery cells. The key is to choose the relative characteristics of lithium batteries based on the time of power consumption. For example, in the ultra-low temperature natural environment, select ultra-low temperature lithium batteries. If the lithium battery cells operate at high temperatures, then Choose high-temperature lithium batteries and charge and discharge high-current polymer batteries, even if the lithium batteries have low charge and discharge characteristics. This is very critical. If you make a mistake, not only will the assembled lithium battery pack not meet the estimated requirements, it may also cause a safety accident.
The second is to choose the relative rechargeable battery accessories.
The equipment is mainly connected with aluminum alloy parts for serial connection or series application of transmission lines and lithium batteries. The selection of such parts should be based on the charging and discharging regulations of lithium battery installation. In addition, the charging and discharging regulations of rechargeable batteries should be considered, and should be avoided as much as possible. The resistor of the raw material itself prevents the consumption of electromagnetic energy.
The installation and installation of lithium batteries should pay attention to the difficulties.
When selecting lithium batteries for assembling lithium batteries, in addition to paying attention to the quality of the well-known brand of lithium batteries, you should also pay attention to the lower the reason for the deviation of the consistency of the lithium battery's intermediate working voltage, internal resistance, volume, charge and discharge characteristics, etc. The better.
It is not allowed to mix the new and old rechargeable battery lithium batteries, which will destroy the new rechargeable battery lithium batteries too quickly and endanger the service life of all lithium battery packs;
Lithium batteries have different characteristics. Cores cannot be mixed, that is, high-temperature rechargeable batteries cannot be mixed with general rechargeable batteries, and ultra-low-temperature rechargeable batteries cannot be mixed with high-temperature rechargeable batteries.
4. When assembling lithium batteries, it should be noted that rechargeable batteries cannot be used in endless series and parallel circuits, and the quality of lithium batteries and the level of the intelligent management system of rechargeable batteries are limited;
Pay attention to short-circuit fault conditions during the whole installation process to prevent accidents;
After a safety accident occurs, the countermeasures that can be resolved safely should be worked out in advance;
