DIY of 48v LiFePO4 Battery Pack

Lithium iron phosphate battery assembly tutorial, how to assemble a 48V lithium battery pack?

Recently, I just want to assemble a lithium battery pack. Everyone already knows that the positive electrode material of the lithium battery is lithium cobalt oxide and the negative electrode is carbon. To assemble a satisfactory lithium battery pack, select a reliable quality lithium battery, and select a suitable battery block, and only a certain amount of technical personnel is required. The editor below has compiled a set of detailed tutorials on how to assemble a 48V lithium battery pack by yourself. I hope it will be helpful to you.

Lithium battery assembly tutorial, how to assemble lithium battery by yourself?

●Before assembling the 48V lithium battery pack, it is necessary to calculate according to the product size and the required load capacity of the lithium battery pack, and then calculate the capacity of the lithium battery pack to be assembled according to the required capacity of the product. Choose lithium batteries according to the calculation results.

●The container for fixing the lithium battery also needs to be prepared, in case the lithium battery pack is arranged, it will change when it is moved. The material to isolate the lithium battery string and for better fixing effect, glue every two lithium batteries together with adhesive such as silicon rubber.

●First place the lithium batteries neatly, and then use materials to fix each string of lithium batteries. After fixing each string of lithium batteries, it is best to use insulating materials such as barley paper to separate each string of lithium batteries. The outer skin of the lithium battery is damaged, which may cause a short circuit in the future.

●After arranging and fixing, you can use the nickel tape to carry out the most important serial steps. After the series steps of the lithium battery pack are completed, only the subsequent processing is left to end. Bundle the battery with tape, and cover the positive and negative poles with barley paper first to avoid short circuits due to errors in subsequent operations.

1. Choose suitable batteries, battery type, voltage, and internal resistance. Please balance the batteries before assembly. Cut the electrodes and punch holes.

2. Calculate the distance according to the hole and cut the insulation board.

3. Install the screws, please use flange nuts to prevent the nut from falling off, and connect the screws to fix the lithium battery pack.

4. When connecting and soldering the wires and connecting the voltage collection wire (equalization wire), do not connect the protection board to avoid accidental burnout of the protection board.

5. The insulating silicone gel is fixed again, this silicone gel will solidify after a long time.

6. Install the protection board. If you forget to balance the cells before, this is the last chance before the lithium battery is assembled. You can balance it through the balance line.

7. Use an insulating board to fix the entire battery pack and wrap it with nylon tape, which is more durable.

8. To package the cell as a whole, please be sure to fix the cell and the protection board. Our cell can still work normally when it is dropped from a height of 1 meter.

7. Use an insulating board to fix the entire lithium battery pack and wrap it with nylon tape, which is more durable.

8. To package the cell as a whole, please be sure to fix the cell and the protection board. Our cell can still work normally when it is dropped from a height of 1 meter.

9. Both output and input use silicone wire. As a whole, because it is an iron-lithium battery, the weight is half of the same acid battery.

10. After the tutorial is completed, we have done a test after the completion of the lithium battery, which can meet our requirements.

How to assemble a satisfactory lithium battery pack?

1: Choose a good quality and reliable lithium battery pack. At present, the consistency of the lithium battery of Energy Storage is good, and the battery is also good.

2: It is necessary to have a sophisticated lithium battery equalization protection board. At present, the protection boards on the market are uneven, and there are analog batteries, which are difficult to distinguish from the appearance. Choose a better battery pack controlled by digital circuits.

3: Use a special charger for lithium batteries, do not use a charger for ordinary lead-acid batteries, and the charging voltage must match the equalization starting voltage of the protection board.

Lithium battery assembly prospects:

With the development of lithium battery packs and the continuous maturity of commercial production technology, the cost of products has dropped significantly, and its technical indicators are better than traditional batteries. It has been widely used (mainly used in digital products at this stage). The battery pack industry scale will reach 27.81 billion U.S. dollars. By 2019, the industrial application of new energy vehicles will increase the industrial scale to more than 50 billion U.S. dollars.
