You can assemble the 48V lithium battery yourself and follow your method:
//----------------//
Take 60 mobile phone electrical boards of the same model, then connect 5 groups in parallel, 12 groups in parallel and 12 groups in series. Connect this to an electric car to replace the lead acid battery?
//----------------//
The above method is workable, but there is a problem: s ensure your battery is consistent Have good sex.
If you want to assemble the lithium battery PACK by yourself, it is recommended to select the battery cells according to the size of your product. If you are using 18650 lithium battery cells, then design your battery PACK. recommends a 13-string structure.
The picture below is a 48V lithium battery assembled by Battery Capital yourself. You can refer to it.
Detailed explanationllee: The red line of the 48V lithium battery in the picture above represents the positive electrode, the blue line represents the negative electrode and is also the discharge line, and ** is the charge line. The battery protection panel uses the same port design. Although the whole battery looks a bit ugly, but it is also the first time I designed a battery PACK. I assembled the 48V lithium battery by hand. a feeling of accomplishment and joy.
I hope Battery Capital can help you, and I hope the success and joy will be extended to everyone who looks at the 48V lithium battery.
< h3>What is the production process of lithium iron phosphate?Manufacturing the positive and negative electrode pole pieces involves a series of tasks, including mixing and pulping. Then use a separator to separate the positive and negative electrodesatives to avoid short circuits, then wind or laminate the assembled pole pieces and solder the tabs to form the battery core. Generally, the battery core is placed in the battery case and electrolyte is added. Forming and sealing.
What are the processes for lithium batteries?
The production process of lithium iron phosphate is: Lithium iron phosphate batteryThe assembly and production process is divided into three main sections, one is the production of the pole pieces, and the other is the manufacturing of cells, and the third is the assembly of the battery. In the assembly and production process of lithium iron phosphate batteries, the production of pole pieces is the basis and the production of battery cells is the core. Battery assembly is related to the quality of the battery at the lithium finished. Select the appropriate battery cell. Battery cell type, voltage and internal resistance must match. Please balance the battery cells before assembly. Cut the electrodes and drill holes.
Lithium iron phosphateMain battery materials
There are four important raw materials for the production of lithium iron batteries phosphate, namely positive electrode materials, negative electrode materials, electrolytes and separators. Among cathode materials, the most commonly used materials are lithium cobalt oxide, lithium manganate, lithium iron phosphate and ternary materials. The cathode material occupies an important part, because the performance of the cathode material directly affects the performance of the lithium-ion battery, and its cost also directly determines the cost ofbattery.
Among the negative electrode materials, currently the negative electrode materialsMainly natural graphite and artificial graphite. As one of the four main components of lithium iron phosphate batteries, negative electrode materials play an important role in improving the capacity and cycle performance of batteries, and are the core of the industry intermediate of lithium-ion batteries.
Market-oriented membrane materials are mainly polyolefin membranes based on polyethylene and polypropylene. In the structure of lithium-ion batteries, the separator is one of the key internal components. The performance of the separator determines the interface structure, internal resistance, etc. of the battery and directly affect the capacity, cycle and safety performance of the lithium-ion battery. Excellent separators play an important role in the aimprovement of overall performance. battery.
The electrolyte is generally prepared from high purity organic solvents, lithium salts of electrolyte, necessary additives and other raw materials under certain conditions and in certain proportions. The electrolyte serves to conduct ions between the positive and negative electrodes of lithium ion batteries, ensuring that lithium iron phosphate batteries obtain the advantages of high voltage and high specific energy.
The manufacturing process of 3C lithium batteries is divided into four procedures:
The basis is the production of pole pieces
The heart is the assembly of battery cells.
The key process is cell activation, which includes battery formation, capacity division and testing.
The final step is battery packaging. battery, which is related to quality. to beat iti.e finished.
In the production of 3C lithium batteries, each step directly affects the quality and safety of the battery. The performance tests of 3C lithium batteries include basic performance, safety performance, environmental performance and electrochemical performance. During the test, the shrapnel microneedle module can transmit current between 1-50A, with strong overcurrent capability and an average of 20W. The battery life can effectively improve the efficiency of testing 3C lithium batteries and ensuring efficient and safe testing.
