Introduce 18650 lithium battery assembly method and tutorials

Source: 2020 - 04 - 18650 lithium battery assembly at 19 clicks: they time the latest technical requirements: assembly 18650 lithium-ion battery pack must be very skilled, 18650 lithium battery assembly process method, including the 18650 electric power energy storage battery assembly diagram, autonomous mobile trolley with lithium battery assembly test 18650 points, the sun can use 18650 lithium battery assembly considerations, etc. , each 18650 lithium-ion battery pack assembly of batteries, battery protection board, battery materials, battery materials, battery terminal has a strict standard, and see it together. A, 18650 lithium-ion battery assembly note: 1, a single 18650 lithium battery must pay attention to the welding, including tin welding and spot welding have not falls off phenomenon. 2. A single 18650 lithium batteries should be paid attention to when choosing the battery internal resistance, voltage and capacity, must conform to the requirements of customers. 3. A single MOS 18650 battery, IC, and the lithium battery circuit board is basically by the electronic engineers design and test. Lithium battery protection board 4 18650. Assembly packaging lithium battery, must follow the lithium battery factory process control plan, and according to the relevant product standards and operation documents for production. 5. 18650 lithium battery assembly according to the customers' confirmation standard parameters for testing. 6. Best before assembly 18650 lithium batteries to confirm process and process, to avoid mass defect. 7. Suggestions according to the standard, after the completion of 18650 lithium battery assembly to packaging and weighing of the battery, and battery with carton label in the warehouse. Ii. 18650 lithium battery assembly diagram 1. If 18650 is made in the process of battery assembly 24 v lithium-ion battery pack, you must first welding and assembling battery. Small assembling a 24 v lithium-ion batteries, also can say 18650 lithium battery assembly 24 v wiring diagram as shown in the figure below. 24 v18650 lithium battery assembly drawing 2. 18650 lithium-ion batteries in the same assembly wiring diagram. If you can do is 24 v, 48 v you basically can do. Three, 18650 lithium-ion battery assembly tutorials in 18650 lithium battery assembly methods according to the structure of the battery, the structure of the different package lithium-ion battery pack assembly method is different, more than 18650 lithium-ion battery pack list and must pay attention to before assembly, all think battery of battery assembly is very simple, basically similar to the following a string of 1 and 18650 lithium battery assembly, 18650 lithium-ion battery encapsulation process skills to analyze, can start from simple 18650 lithium battery assembly, in English, so use rise more convenient in the future. Through the above the battery assembly video teaching, is very simple to do a series of 1 and lithium battery, of course, these also need to pay attention to the following points. 1. Cells arranged orderly, facilitate maintenance in the future. It is best to use the standard 18650 battery CARDS. 2, good welding, welding method of the most popular on the market at present is to use nickel welding spot welding, also can use the soldering iron, good contact point when you spot welding. 3. After soldering, the battery pack wiring must be clear. 4, to do a good job of waterproof thermal insulation, it is better to cut out a piece of highland barley paper or asbestos material. 5. The most important of all, before the battery internal resistance welding, the current voltage error should not exceed 0. 05v! Conditions must be equipped with lithium battery protection board dedicated, prevent the overshoot and over discharge. Measure the voltage of each circuit after welding. 6. New battery assembly after a period of time, should carry on the grouping test voltage.
