May I ask the four-way Tesla charging pile, is the four-way emergency charging pile sold?

I don't know much about this, brother.

Which one is better, Hangzhou Qianna and charging pile and Qihang charging pile.

Hangzhou Qianna is OK.

Fifty-fifty. Compared with Hangzhou Qihang charging pile, it is better to have a thousand nanometers.

In fact, the former is better.

Pls which of these two is the former.

Qianna. Qianna came out earlier, didn't he?

Hmmm. His maturity and stability are not more ideal.

The quick rush is very harmful to the battery. Generally, the electric sail with its own charger is about the current, and the current of the quick rush is 9-11A, so it will hurt very much.

1.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 usually said that the electric answering car is a vehicle that uses the battery as the energy **, and converts the electrical energy into mechanical energy movement through the controller, motor and other components to control the current and change the speed.

2.The first electric car was built in 1881 by French engineer Gustave Truf, a three-wheeled vehicle powered by a lead-acid battery, and it was powered by a DC motor.

Fast charging refers to a charging method that can make the battery reach or approach a fully charged state within 1 5 hours. It is commonly used for traction batteries when they need to return to a fully charged state in a short period of time. Fast charging is detrimental to the performance and life of the battery.

The normal charging time of the battery is about 10 20h, and how to quickly charge the battery without damaging the performance and life of the battery is a hot research topic that people pay attention to.

Fast charging circuit features.

1. After the output voltage is set (such as 36V), if the charging bottle plate falls off and is disconnected, causing a certain group of batteries to fail or a short circuit, the battery terminal voltage will be reduced or zero, and the charger will have no output current.

2. If the voltage of the charging bottle deviates from the set voltage, such as the set voltage is 36V, and the battery is connected to 24V, 12V, 6V by mistake, etc., the charger has no output current, if it is set to 24V and mistakenly connected to the 36V battery, the output voltage of the charger is lower than the battery voltage, so it cannot be charged to the battery.

3. If the two output terminals of the charger are short-circuited, the trigger circuit of the SCR in the charger cannot work, so the thyristor is not conductive, and the output current is zero.

4. If the positive and negative poles of the battery are mistakenly connected in reverse during use, the thyristor trigger circuit will be reversed cut-off, there will be no trigger signal, the thyristor will not be turned on, and the output current will be zero.

5. The use of pulse charging is conducive to prolonging the life of the battery. Because the low-voltage alternating current is pulsating DC after full-wave rectification, only when its peak voltage is greater than the battery voltage, the thyristor will be turned on, and when the pulsating DC voltage is in the trough area, the thyristor is reversed and cut off and stops charging the battery, so it is pulsating DC that flows through the battery.

6. Fast charging, full self-stop. Since the voltage at both ends of the battery is low at the beginning of charging, the charging current is large. When the battery is about to be sufficient (the terminal voltage of the 36V battery can reach 44V), the charging current will become smaller and smaller as the charging voltage is getting closer and closer to the peak of the pulsating DC output voltage, and it will automatically become trickle charging.

When the voltage at both ends of the battery is charged to the maximum value of the peak of the rectifier output, the charging process stops. After testing, the three electric vehicle batteries are 36V (12V 12Ah three cells in series), and it only takes a few hours to fully charge with this charger.

It's actually used to charge large batteries, and now it's used to charge small batteries, of course, fast.

The biggest difference between a fast charging station and an ordinary charger is that the current is strong, which is 4 to 6 times the current of an ordinary charger, which is a strong charge and has a greater impact on the battery. As a last resort, it is recommended to charge less.

If you use a fast charger to charge an electric vehicle for a long time, it will reduce the battery life to a certain extent.

The working principle of the electric vehicle fast charging station is to increase the current to achieve the purpose of "fast charging".

The current of the fast charging station is generally about 9A, while the ordinary charging current at home is about 2A, compared to the current of the fast charging station is 5 times that of the family! Due to the lack of pulse protection, the fast charging station can be fully charged in a short time, but this will cause great damage to the battery plates, which will accelerate the vulcanization and aging of the plates, and even cause the plates to fall off and break down.

The fast charging station of electric vehicles is welcomed by the majority of car owners because of its fast charging speed and wide range of convenient charging, which can greatly meet the needs of car owners for fast charging and immediate access to the road.

It is precisely because of the extremely fast charging speed that the damage to the battery is also great.

1) Use fast charging to achieve the purpose of charging the electric car. Commonly used DC charging, the power of fast charging is about; The purpose of charging can be achieved in a very short time.

2) Fast charging will cause the battery to lose water and dry out, and at the same time generate a lot of heat, generate a lot of hydrogen and oxygen, and the internal air pressure will become high, which will easily make the plastic shell of the battery soft. Frequent fast charging, or the use of unqualified and aging chargers, is easy to make the battery inflated, deformed, affect the performance of the battery, and even scrapped.

It is recommended that you usually use a slower charging smart charging pile to charge, which requires 6-8 hours of trickle charging to charge, and its biggest advantage is that the charging is stable, safe, and prolongs the service life of the battery.

The damage of the fast charging station to the battery of the electric vehicle is very serious, the fast charge is generally the person who suddenly has no power during the driving and urgently needs to be charged in a short period of time to use the fast charge, and in fact, the fast charge in a short time can not ride very far, I have rushed once, in the place of repairing the electric car, 1 yuan can only be charged for 10 minutes, I only rode about 1000 meters after charging for 10 minutes and ran out of power. The charges are not cheap either. Instead of fast charging, I prefer to choose a slow charging station, which not only charges reasonably but also prolongs the battery life and eliminates charging hazards.

The quick rush is very harmful to the battery. Generally, the current of the built-in charger is about right, and the current of the quick rush is 9-11A, so it will hurt very much.

1.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.

2.The first electric car was built in 1881 by French engineer Gustave Truf, a three-wheeled vehicle powered by a lead-acid battery, which was powered by a DC motor.

It is not recommended, it is a high-current charge, which is extremely harmful to the battery, so do not use it as a last resort.

An EV fast charging station is a device that can quickly charge an electric vehicle. It is generally used for emergency use of electric vehicles. The advantage is that the electric car can be fully charged quickly so that it can drive normally.

But the disadvantage is that it can damage the battery battery. Therefore, at present, the community units are generally charging stations that use slow charging. Our unit used a Shangyiyuan brand slow charge, which feels pretty good, and you can also learn more about it.

Fast charging of electric vehicles is easy to damage the battery, slow charging is the same as usual charging at home, remember that Shouyuan has a fast charging that does not harm the battery, intelligent intermittent pulse charging, which has a repair effect on the battery.

Because the power of fast charging is greater than that of general chargers.

Take QC fast charging as an example, the general QC fast charging is 5 volts 2 amps 10 watts, 9 volts 2 amperes 18 watts and 12 volt ampere 18w, and these output methods will also be controlled by the mobile phone to provide according to the current needs of the mobile phone. The ordinary charger only has 5 volts 1 amp or 2 amp output, and the power is 5 to 10 watts.

If you can't understand the above, you just need to know that boiling a pound of water, the higher the power, the faster it will be boiled, and the battery is equivalent to water.

It's actually used to charge large batteries.

Now it is used to charge small batteries, of course, fast.
