What is the principle of how to connect the split battery of electric vehicles?

<> connected in series, the voltages are added and the capacity remains the same, which is the basic principle.

Each battery box is connected in series, 4 cells, 1 x 12V, a total of 48V. or 3 batteries for a total of 36V.

The split box also needs to look at the voltage of the electric vehicle, which is generally also connected in series. It is recommended that you go to the local designated after-sales service for consultation.

1. Lead out the positive and negative wires.

Electric vehicle batteries are all series power supply, the first piece leads out the positive wire for backup, and the negative pole is connected to the positive pole of a piece, so repeat, and the last piece leads out the negative pole for backup, and the battery pack is completed.

2. Welding. For soldered battery packs, the motor is a piece of copper with an eye in the middle, which needs to be wound with wire and then fixed with solder. The soldering iron can be evenly dipped in solder.

3. Tighten the screws.

Of course, there is a simpler one, the battery electrode is the kind with screws, and this kind of direct tightening of the screws is good.

4. Buy a special plug.

The most convenient thing is to buy the kind of special plug, which is suitable for battery electrodes are sheet-shaped, and you can plug it in. However, it is easy to loosen due to jitter, so it needs to be checked regularly.

5. The inspection is completed.

After installation, check the circuit to prevent the wrong battery from being burned, turn on the power supply after checking that it is correct, and try whether the battery car is powered on.

6. Connect to the instrument line.

If you disassemble the instrument, you will find that the instrument has 2 wires, one is connected to the anti-theft interface and one is connected to the instrument line of the controller. If you remove the handlebar, you will find that there are only 3 wires on the handlebar, which can be found by color, or measured with a multimeter.

7. Connect the brake and disconnect the wire.

Remove the brake lever will find that the brake lever has 2 wires, the brake lever is a normally open switch, and the 2 wires can be directly connected to the controller brake power-off.

The connecting line is connected in series.

Lines, 12v 2 per box, 24v 2 per box, about this way.

The voltage of a battery is 12 volts four, the voltage of the battery in series is 48 volts, considering the easy installation of the battery, it is to put the two batteries in a battery box, therefore, the battery between the two battery boxes is also a series relationship, the principle of series connection is that the positive and negative poles between the batteries are connected.

The two boxes are also connected in series to form 48V

Each battery box is connected in series, 4 cells, 1 x 12V, a total of 48V. or 3 batteries for a total of 36V.

<> The connection of the two sets of batteries of the electric vehicle is as follows:

1. The two sets of batteries are directly 48 volts together, and the positive and negative are connected to the negative. Completely ready to use.

2. However, it is best not to use up the electricity when used together, and charge it when using half or less than half, and you can still charge it with the original charger, but you must grasp the charging time.

3. It is best to charge the two sets of batteries separately. This is very useful for electric motorcycles, and it can only increase the mileage of electric vehicles, and there will not be much change in power.

Soldering: For soldering battery packs, the motor is a piece of copper with an eye in the middle, which needs to be wound with wire and then fixed with solder. The soldering iron can be evenly dipped in solder, of course, there are simpler ones, the battery electrode is the kind of screw, this kind of direct tightening of the screw.

Precautions for electric vehicle batteries.

In the process of use, the charging time should be accurately grasped according to the actual situation, with reference to the usual frequency of use and mileage, and also pay attention to the capacity provided by the battery manufacturer, as well as the performance of the supporting charger, the size of the charging current and other parameters to grasp the charging frequency. In general, the battery is charged at night, and the average charging time is about 8 hours.

If it is shallow discharge (the driving range is very short after charging), the battery will be fully charged quickly, and if it continues to charge, it will be overcharged, resulting in water loss and heat generation of the battery, reducing the battery life. Therefore, it is best to charge the battery once when the discharge depth is 60%-70%, and it can be converted into riding mileage when it is actually used, and the necessary charging is carried out according to the actual situation to avoid harmful charging.

The batteries are connected in series, that is, the positive pole of one battery is connected with the negative pole of another battery with a wire, and then the remaining positive electrode and negative electrode are drawn out for electric vehicle electricity.

The connection method is as above, and the middle two sections can be removed.

There are four ways to do this:

The negative electrode of the 1st battery (blue pile) and the positive electrode of the 2nd section (positive pile);

The negative pole of the 2nd battery is connected to the positive electrode of the 3rd section;

The negative pole of the 3rd battery is connected to the positive electrode of the 4th section;

Finally, the positive pole of the first battery and the negative pole of the fourth section are left, which are connected to the two terminals of the charging hole of the electric vehicle.

The positive pole of the charger is connected to the positive pole of the battery, and the negative pole is connected to the negative pole.

Electric vehicles, i.e., electrically driven vehicles, also known as electric vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. It is generally said that electric vehicles are vehicles that use batteries as energy**, and convert electrical energy into mechanical energy movement through controllers, motors and other components to control the current and change the speed.

The first electric car was built in 1881 and was invented by French engineer Gustave Truf.

Changes in consumer preferences will also affect changes in the competitive landscape of electric vehicle companies. The change in consumer consumption preferences changes with the change of personal income level. With the improvement of the economy, the improvement of residents' consumption level, the awareness of energy conservation has increased, and the quality requirements for electric vehicles have also increased.

In the future, the potential of the electric vehicle industry is huge, and the industry consumption will exceed 70 billion yuan in five years.

When parking, choose a shade and rain shelter, do not be exposed to the scorching sun, do not get drenched in heavy rain, and make the electrical appliances water and damp. With its green, economical and convenient characteristics, electric bicycles have become a favorite means of transportation for the people, and play a positive role in alleviating the energy crisis and dredging urban traffic congestion. However, the inconvenience of charging, the vulnerability of electric vehicles or batteries, and the tens of millions of used batteries discarded each year have a negative impact on consumers and the environment.

The red pole of the battery is the positive pole, the black pole is the negative pole, and the battery is connected in series in the battery box, that is, the positive pole of one battery is connected to the negative pole of another battery.

Connect the positive pole of the two cars first, and then connect the negative pole, this sequence is to prevent accidental short circuit. When the negative pole is connected, there are many cars whose negative terminal posts are blocked by other components and cannot be connected.

It can also be found on any metal part of the car body, because the whole body is equivalent to the negative pole of the battery. The point is not to take it the other way around.

Connecting the positive and negative electrodes will cause the engine, computer and other parts to burn out, because it is equivalent to two batteries in series, and the voltage is too high. When the battery cord is removed by fire, remove the negative electrode first, and then the positive electrode.

The battery is dead and cannot be started, which many people have encountered, especially older cars. There are several reasons why the battery is out of power, first of all, the battery life is up, and the power storage is greatly reduced, so the car cannot be started if it is not opened overnight; The second is that the vehicle cannot be placed for a long time, and the natural discharge leads to power loss; There is also a situation caused by forgetting to turn off the electrical equipment, or the vehicle is faulty and leakage, resulting in a loss of power in a short time.

So once the battery loses power and can't catch fire, it is generally to call for rescue or find a car to take the electricity by yourself. Call rescue worry-free, do not need to operate yourself, the disadvantage is that you generally have to wait for a long time, and it may also be charged. If you can use electricity, you will save a lot of time, so how to operate it?

You also need to have a car with electricity, or an emergency starting power supply is fine. Next, let the two cars get close enough, and the battery line can reach the batteries of the two cars, which can be head to head or side by side. Then connect the battery wire, the formula is that the positive electrode is connected to the positive electrode, and the negative electrode is connected to the negative electrode.

1. First of all, buy a new set of batteries.

2. Four batteries need to be destroyed by four or five connecting lines, generally four connecting lines.

3. Screws on the battery connection line.

Air switchIt can prevent the accident of electric vehicle short circuit and burning.

5. Electric vehicle wiring harness.

6. Battery connection. A battery is divided into positive and negative poles, the red end is the positive electrode, and the blue end is the negative electrode, Wang ordered to use a connecting wire to connect the red end to the positive electrode of the battery (the red end), and the black end to the negative electrode of another battery (the blue end), and then each battery is connected in this way, and finally the starting and ending points are the positive electrode and the negative electrode are trapped and purified (that is, the blue end of the battery and the red end).

How to run out of external battery for an electric car:

1) Electric bikes.

Style. One elbow wire and one battery socket, red wire to red wire, black wire to black wire.

2) Electric motorcycle style. The two elbow wires are connected to the red wire, and the black wire is connected to the black wire.

A good arrangement of battery connections can reduce fault points, prevent lines from wearing each other, reduce the causes of fire, and improve the service life of the battery. Customers have less trouble using the battery you install, and our business will be fine.

The advantage of this connection method is that there is no chance of friction between the middle tablet and the battery wire.

Many machines without tableting can be connected as follows.

Question: Can you see the ** I posted, is it right?

With the development of electric vehicles, the batteries of electric vehicles have also developed from the previous 3 12 amp batteries to the current 4, 5, 6, and 12 batteries. The increase in the number of batteries also represents a surge in mileage and speed, as well as higher requirements for battery installation. Proper battery connections reduce wear and tear on the wiring, prevent fires, and increase battery life.

Today I will tell you about the common connection methods of the battery.

1.The most common four-cell connection method is shown in the figure below. In this way, the wiring does not waste wires and does not crimp wires. The connection principle of the block battery is the same as the wiring method above to control the two groups of batteries with air opening. A group of six blocks controls the switching of two groups of batteries with two empty openings.

6.Type 4812 battery connection method for electric bicycles. Solder the battery according to the connection direction of the wires in Figure 1, and then weld the last three wires in the way of Figure 2. In this way, the soldering will not crimp the wire, saving the power cord. 7.How to run out of external battery for an electric car:
