The tutorial for assembling a homemade 60v lithium battery is as follows:
1 To assemble the battery, you must use nickel tape, high temperature. adhesive tape and battery holder.
2. Generally, spot welding is used to connect lithium batteries with nickel. If you don't have a spot welder, you can use sandpaper to polish both ends of the battery and then use a soldering iron. welding.
3. Get the battery line and measure the voltage to see if the capacity is the same. If they are different, do not adjust them together.
4. Then install the battery and battery holder, and arrange them in positive and negative order.
5. Then wrap the temperature resistant tape over it.
6. Use nickel tape to connect the batteries. If you don't have a spot welder, just use a spot ironder electric. By the way, stick the protective panel on the adhesive tape.
7. For the effect of nickel strip spot welding, it is necessary to distinguish which one is connected to which, otherwise it will cause a short circuit.
8. Then solder the protection plate and the plug. Generally, the cover plate will show the connection method in detail, and you can just connect it with wires.
If it is a ternary lithium battery, for a 20 Ah ternary lithium battery, first 3 cells are connected in parallel, then 16 parallel groups are connected in series to form a 60 V60 Ah battery.
If it is a lithium iron phosphate battery with a single 30Ah battery cell, first connect 2 cells in parallel, then connect 19 parallel batteries in series to form a 60 V60 Ah battery.
The production of lithium batteries for electric vehicles ismainly divided into two main stages. One is the manufacturing of lithium batteries and the other is to connect the lithium batteries one by one in series or parallel to achieve the purpose. lithium battery desired for electric vehicles. Voltage, capacity and charge and discharge requirements.
Lithium Battery Assembly Tutorial
1. Prepare three lithium batteries, which must be the same model and cannot be mixed.
2. When assembling the battery box, be sure to connect it in series, otherwise the voltage will not increase.
3. After installing the battery, use a voltmeter to measure it. , and it will be 12V.
4. The magnetic beads are conductive and wrapped in a layer of tin foil.
5. Connect the batteries in series, with the positive pole facing the negative pole, not the other way around.
6. Once the connection is complete, youcan test it and see if it has 12 V.
