Summary: Electric vehicle lithium batteries are batteries that power lithium battery electric vehicles. Environmental problems caused by traditional internal combustion engine vehicles and the shortage of oil resources have made people turn to new energy vehicles. Lithium-ion batteries have become the ideal energy source for the new generation of electric vehicles due to their excellent performance. So how do you assemble lithium batteries for electric vehicles? What are the precautions for using lithium batteries for electric vehicles? Next, let's learn more with the editor. 1. How to assemble lithium batteries for electric vehicles
1. Prepare materials including stainless steel battery boxes to assemble 60V24AH lithium batteries for electric vehicles. Beat themLithium batteries must be batteries for electric vehicles.
2. Put 20 lithium batteries in a string, for a total of 8 strings.
3. Connect 8 strings of lithium batteries in parallel and use separators and tape to insulate them.
4. Secure with tape and solder the protective wire in series.
5. Use heat shrink film to wrap and insulate the soldered lithium batteries, connect them to the protection boards and insulate them to prevent short circuit.
6. Short circuiting of lithium batteries is very harmful. After wrapping the lithium battery with heat shrinkable film, the assembly of the electric vehicle lithium battery is completed.
2. Precautions for using lithium batteries for electric vehicles
1. Temperature
Temperature also has a big impact on the lifespan of lithium batteries. This point can provocate the depletion of lithium batteries at the time the electric vehicle is turned on, and an overheated environment will reduce the capacity of the electric vehicle battery. Remember not to expose the electric vehicle to the sun.
2. Large current
For example, the 18650 battery cell is discharged at 3C and your electric car is 8000W. The battery cell used is less than the discharge current of your electric car. car. This will cause lithium. If the battery temperature is too high, the current will be too large, the service life will be shortened, and the battery will be discarded. If your electric vehicle has very high power and very fast speed, it is recommended. choosing 18650 battery cells with 10C current It is obvious to choose the suitable battery cell. Very important.
3. Fully Charged Storage
Full battery charge in bedternary hium is 4.35V. Currently, protection boards on the market stop charging at 4.2V, so many people buy lithium. electric vehicles. Batteries are said to not have as much capacity as the rated capacity. In fact, this is the reason why, generally, when storing electric vehicle lithium batteries for a long time, it is best to charge them to 50%. For example, when you buy a new cell phone, many of them are turned on at 50% power.
If the battery is fully charged for a long time, the capacity of the lithium battery will be reduced. With the exception of iron phosphate and lithium, both of these elements can be stored at full charge. You should also pay attention to choosing a better quality protective board. The biggest taboo of lithium batteries is overshooting and discharge extransfer. it will be scrapped, overrun will inevitably cause bulging and scrapping.
3. Is lead acid battery or lithium battery better for electric vehicles?
As an electric vehicle battery, lead acid battery has design advantages. The advantage is the relatively large open circuit power it provides (compared to lithium batteries). A 12V battery only needs to be made into a battery, while the lithium battery is used as a power battery. It may be necessary to connect several of them in series to form a battery. For power battery design, lead-acid batteries can be relatively easy to implement, while lithium batteries require many problems in design, subsequent charging, use and maintenance. In terms of manufacturing costs, batteriesCurrent power s are lower in lead-acid batteries and higher in lithium batteries, but lithium batteries are the future development trend.

The tutorial to assemble a homemade 60v Lithium battery is as follows:
1. To assemble the battery, you need to use nickel tape, high temperature tape and a 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 an electric soldering iron. 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 grouParallel pes 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 two cells in parallel, then connect 19 parallel batteries in series to form one 60 V60 Ah battery.
The production of lithium batteries for electric vehicles is mainly 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 and capacity as well as charging and discharging requirements
