How do I assemble a 48V lithium iron phosphate battery pack myself?


1.Disassemble the battery pack, measure the internal resistance of each battery cell, and re pair it; Spot welding and reassembling the battery pack.

2.Calculate the distance based on the holes and cut the insulation board.

3.Tighten the screws, please use flange nuts to prevent the nuts from falling off. Once the screws are connected, the lithium iron phosphate battery pack can be fixed.

4.When connecting and soldering wires and voltage acquisition lines (equalization lines), do not connect external protective boards to avoid accidental burning of the protective boards.

5.Place the protective board and then package the battery cells as a whole,

6.Secure the entire battery pack with insulation board and seal it with nylon tape.

7.The final packaging is completed, and the output and input are all made of silicone wire.

Required tools: Electric grinding (stainless steel saw blade, small grinding wheel, sandpaper), pointed nose pliers, multimeter, internal resistance meter, large pond capacitor spot welding machine, T12 welding table.

Required consumables: nickel tape, gold finger high-temperature tape, fabric tape, barley paper, heat shrink film, wire, XH2.54 terminal wire.

What are the issues to pay attention to when assembling lithium iron phosphate battery packs?

1. To assemble a satisfactory lithium iron phosphate battery pack, it is necessary to choose high-quality and reliable lithium iron phosphate batteries, and have excellent lithium battery balance protection boards. Currently, there are various types of protection boards on the market, and there are also analog batteries that are difficult to distinguish from the appearance. Therefore, it is necessary to choose a digital circuit with good control, such as good storage electrical.

2. It is necessary to have a certain level of technical knowledge, as selecting suitable battery blocks requires that internal resistance and other parameters should not be too large, and the difference in parameters should not be too large.

3. Considering the selection of charging boards, it is not recommended to try those without a certain foundation as there is a risk of explosion.

4. Lithium battery packs should be well waterproof and insulated, and the batteries should be arranged neatly to facilitate future maintenance.

5. After using the newly assembled lithium battery pack for a period of time, it is necessary to group and check the voltage of the batteries, the internal resistance of the batteries before welding, and the current voltage error should not exceed 0.05V to prevent overshoot and over discharge.

What are the materials used to assemble lithium iron phosphate batteries?

The materials commonly used in lithium batteries include electrolyte, CMC, lithium cobalt oxide, separator, PVDF, high-temperature adhesive paper, NMP, graphite negative electrode, SBR, oxalic acid, copper foil, aluminum foil, etc. These are the components of lithium iron phosphate batteries.

The above is the tutorial and steps for assembling lithium iron phosphate batteries. In fact, it is not difficult to assemble lithium battery packs by yourself, but it is necessary to have professional technical personnel to guide and have a certain knowledge of lithium batteries in order to be safer.
