Is the safety of the charging column of new energy vehicles reliable?

First of all, no matter where the charging column is installed, you must get the installation qualification of the charging column, if it can be installed, you need to pay attention to the following issues when installing:

The fire department needs to issue relevant safety instructions, and since the voltage used by the charging column is higher than the voltage of the household electricity, the safety of electricity has become the primary concern.

It should be noted that whether it is a unit or a home, the charging column must have a suitable size of space.

Before installation, the charging column manufacturer or the power department needs to come to the site for on-site investigation.

It is necessary to discuss with the property whether it can be installed, if it can be installed, what relevant materials need to be prepared, if it cannot be installed, you need to contact the manufacturer or merchant and ask them to communicate.

Whether the private installation of the charging column can be subject to the manufacturer's warranty. If you install a charging pole in an open-air parking lot, you should pay attention to how to protect the charging pole in case of bad weather such as rain and snow.

At the same time, if a charging column is installed in an underground garage, it is necessary to measure the dimensions of the charging area, the distance between parking spaces. Determine the installation location of the distribution box, understand the situation of the underground garage, whether there is water leakage or moisture, whether there is sufficient light, and whether there is a stable signal.

In general, although new energy vehicles have brought us a lot of convenience, charging safety must be put in the first place. After all, there are a lot of safety risks. In addition, while promoting new energy vehicles, manufacturers, property and power departments should unite the front, so that the people can use new energy vehicles while ensuring the safety of usersLet our use environment be greatly improved, so that more and more people can use new energy vehicles conveniently.

The charging column of the current new energy vehicle is a bit unreliable, and the technology is not good.

Because there are still certain design defects in the charging column of new energy vehicles, its safety still has certain risks.

It's not very reliable, but it can still be charged, just remember to pay attention.

The safety of batteries needs to be examined from the four levels of cell, pack, system and functional safety.

I feel reliable. Because the new energy charging piles have passed the safety standards, there is no quality problem.

It should be very safe, after all, the current technology is still very good.

Security is still very high, but there are still some uncontrollable factors.

It should still be a technology that has always been not very mature, and it still needs some writing and perfection in development.

It is safe for new energy vehicle charging piles to charge when it rains.

If it is a national standard charging pile that meets the IP54 standard, there is no problem in operating the charging on rainy days. The main thing is to be more compliant with the norms and operate safely.

Generally speaking, the national standard stipulates that outdoor charging piles must reach the protection level of IP54, and the construction of outdoor charging piles must strictly comply with the fire protection and lightning protection safety acceptance standards of charging piles. In addition, the charging pile should have a leakage protection switch inside the design. Therefore, it is safe for new energy vehicle charging piles to charge when it rains.

Tips for charging in the rain:

1.Before charging and connecting, carefully check whether there is any water or foreign matter in the connector interface on the pile side and vehicle side, and clean or wipe it before connecting.

2.If you are connecting the battery when it rains, please use an umbrella or other item to shield it during the connection.

3.If you find that the charging station is flooded by heavy rain, please do not rush to the charging pile to avoid electric shock.

When using outdoor charging equipment, it is important to pay attention to the following requirements:

When parking, please choose a high position on the ground to avoid the vehicle battery being soaked in water;

Check whether the charging gun has been soaked in rain, whether there is water or debris in the gun, check and clean up the water and debris in the charging gun, wipe the inside of the gun head before use, when pulling the gun from the charging pile, pay attention to prevent rain from splashing into the gun head, and be sure to ensure that the muzzle of the gun is facing down when moving the gun;

When opening the cover of the car charging inlet, it is important to ensure that it is not exposed to rain to avoid rain splashing into the outlet;

When plugging in or unplugging the charging cable, be sure to use rain gear to prevent rain from splashing into the charging cable and the car charging socket;

After the charging is completed, be sure to plug the charging gun back into the muzzle of the charging pile, ensure that the muzzle of the charging gun is facing down during movement and use rain gear when plugging the charging gun back into the charging pile.

The charging piles of new energy vehicles are safe to charge when it rains, and the interface design has reached IPx 6 - IPX 7 (IPX is an internationally accepted waterproof level certification system.) In outdoor, diving, and many other instruments and equipment are used to mark the waterproof level of the product, which is the most common technical index. The waterproof level, that is, some splashes or even heavy rain will not cause damage to the parts.

It is only that when a large amount of water enters the charging interface, the charging gun and the charging port cannot be fully contacted, cannot be charged, or the charging pile is a problem that causes power failure, which will not cause any harm to personnel.

5-step charging process specific introduction]:

1. Pull out the gun with an umbrella: you must always have an umbrella in the car, no matter how big the charging gun is, please get off the car with an umbrella when the charging gun is pulled out from the pile, check whether the gun head is intact, whether there is water and other foreign objects inside. (If there are a small number of water droplets, shake them twice.)

This step is to rule out the risk of water ingress caused by the improper operation of the previous charging vehicle owner. At the same time, charging in the rainFor safety reasons, please use an umbrella throughout the whole process to avoid exposing key parts such as the charging gun and charging port to the rain.

2. Confirm that the nozzle is connected correctly: after checking that the charging gun is correct, open the protective cover of the charging port of the body and insert the charging gun. Make sure to hear the click, the charging gun and the charging port are connected, and once the two are connected, it is an airtight whole, and the owner no longer needs to worry about water ingress.

3. Check whether the charging pile is working normally: start charging after the charging gun is plugged in, then you should check the control screen on the charging pile, whether it shows whether it has started charging, if not, see if it is because of the contact problem that causes the jump stop, if it is a connection problem, at this time, you only need to plug and unplug the charging gun in a small way.

4. Cover the charging port as soon as possible after pulling out the gun: After charging, first end the charging process and then pull the charging gun out of the body, and immediately cover the two covers of the body charging port while pulling out the gun.

There are two scenarios:

First, if it is normal and not raining, it is definitely safe to charge, if the charging pile is in line with the protection level of IP54 and above.

The second is that the charging gun has been plugged in before charging and started charging, during which it starts to rain, do not touch the gun head and the charging pile, it is generally safe, and the manufacturer will consider water discharge measures.

If it rains, do not do any charging operation to ensure safety.

It is safe for new energy vehicle charging piles to charge when it rains.

For example, the charging pile of Hi Charge Technology has a national standard charging pile with IP54 standard, and there is no problem in operating charging on rainy days. The main thing is to be more compliant with the norms and operate safely.

Is the new energy vehicle charged, explained as follows:New energy vehicles do not necessarily need to be charged, it can be said that as long as they are charged, they belong to new energy models, but not all new energy vehicles are charged. New energy vehicles include pure electric vehicles, extended-range electric vehicles, fuel cell electric vehicles, solar power generation vehicles, hydrogen engine vehicles, etc., among which fuel cell electric vehicles, solar power generation vehicles, and hydrogen engine vehicles do not need external charging.

Charging method for new energy vehicles:

1. New energy vehicles can be charged directly at home at 220V, and the manufacturer will provide charging tools;

2. It can be charged at the charging pile built outside.

At present, there are three main charging methods for new energy vehicles:

Using the three-prong socket, use the charging cable to charge:

Use the rated current.

No more than 16A standard plug socket, charging directly at home, about 8-10 hours can be fully charged.

There are two specifications of 10A and 16A three-pronged sockets used by home users, and the size of 16A plugs and sockets will be larger. SAIC new energy vehicle.

A charging cable is delivered with the vehicle, one end is connected to a three-prong socket, and the other end is connected to the vehicle charging port to realize charging.

The charging cable distributed by SAIC is 16A specification, so it cannot be plugged into a 10A socket, and do not use all kinds of non-standard adapter plugs to avoid safety risks.

Use an AC charging station.

Carry out charging: Replace the electric car.

Directly in the current of the alternating current is larger.

The charging time is about 4 hours using the charging pile.

The slow charging pile power is usually and 7kW, which depends on the rated input power of the on-board charger. As far as single-phase AC charging is concerned, the rated input current of the current on-board charger is divided into two mainstreams: 16A and 32A, and there are 16*220.

The on-board charger can intelligently identify whether the access is a three-eye socket or a charging pile, even if the power of the on-board charger is 7kw, it will intelligently limit the charging power to the range that the access cable can bear to ensure charging safety.

The above two types of AC charging belong to "slow charging", slow charging time is long, and the AC power supply is converted from a small power on-board charger to DC to charge the battery.

Charging with a DC charging pile:

When connecting an electric vehicle to an AC or DC grid, a DC-powered device with control guidance is used. Generally, only pure electric vehicles on the market are equipped with DC charging function, which is what we call "fast charging".

The fast charging time is short, and the high-power off-board DC charger directly outputs DC to charge the vehicle battery. The power of fast charging piles on the market ranges from 30kW to more than 100kW, and general charging ranges from ten minutes to 2 hours.

In the process of fast charging, the off-board charger and the electric vehicle go through the handshake stage, the configuration stage, and the end of the charging stage. Fast charging puts forward higher requirements for safety, battery life, infrastructure, operation and maintenance.

With the development of charging technology, new charging technologies will continue to emerge, and the charging of new energy vehicles will become faster and more convenient, providing a strong guarantee for the convenience of new energy vehicles.

With the development of charging technology, new charging technologies will continue to emerge, and the charging of new energy vehicles will become faster and more convenient, providing a strong guarantee for the convenience of new energy vehicles.

It's definitely going to be recharged! Those that do not charge are called energy-saving cars.

Can your mobile phone or electric car run normally without charging? This is obviously not going to work!

New energy vehicle charging is charged through the outside public DC charging pile, generally speaking, 80% can be achieved in 30 minutes, and it can be fully charged in about 1 hour, which is still very fast.

Qualified car owners, you can try to charge at home, charging at home is generally through the Pulegu home charging pile or Pulegu household portable charging gun for charging, specific need to use what kind of charging products, you can go to a cat or a certain east to find Pulegu to understand!

There are two charging methods for new energy vehicles, one is to charge with the help of public charging piles, and the other is to use their own charging devices for charging, which is specified below.

1. Use public charging piles for charging

As of August 2019, with the increasing number of brands and numbers of new energy vehicles in society, a large number of public charging piles for new energy vehicles have also been set up. When charging with a public charging pile, pay attention to distinguishing between fast charging and slow charging. Generally speaking, fast charging can be used when charging with public charging piles, and the vehicle can be fully charged in 1-2 hours without delaying the normal driving of the car.

It is relatively fast to charge when using a public charging pile, but it needs to be charged in a special charging area, which is not very convenient in places where there are no public charging piles.

2. Use a home charging device for charging

Charging with a home charger is safer and less expensive. However, the charging speed is relatively slow, and it generally takes 8-10 hours to charge a single charge.

Matters needing attention when charging new energy vehicles:

1. When charging new energy vehicles, the charger and socket must be plugged in tightly to ensure the safety of electricity.

2. Don't charge it when the battery of the new energy vehicle is completely empty, which will not only damage the battery but also cause unnecessary trouble.

Not necessarily. It can be said that as long as it can be charged, it belongs to new energy models, but not all new energy vehicles are charged. New energy vehicles include pure electric vehicles, extended-range electric vehicles, plug-in hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, solar power generation vehicles, and other new energy vehicles.

Fuel cell electric vehicles, hydrogen engine vehicles, and solar power generation vehicles do not require external charging.

The first is the fast charging port. This type of charging port is generally located at the front of the car (JAC IEV5 is the opposite, the same below), which belongs to the DC charging method and requires the use of high-power fast charging piles. The charging time is relatively fast, and it can be charged to 80% in tens of minutes.

The second is the slow charging port. This type of charging port is generally on the rear side of the car, the same as the fuel filling port of gasoline vehicles. This type of charging port requires the use of slow charging piles, which are the ordinary charging piles that prospective car owners mainly consider installing.

The charging pile is a 220V AC input and takes several hours to fully charge. Generally, when buying a car, a charging cable will be given with the car, one end plugged into the car, and the other end plugged into the slow pile.

The third is the emergency charging port. Also known as power bank. Some brands will give one with the car, similar in size to an e-bike charger, with one end plugged into the EV slow charging port and the other end plugged into the family's three-pin socket.

It is very convenient for those residents who are not convenient to install electric piles, but the parking spaces are relatively close to the windows. Just pull a power strip at the window and go out to charge the electric car. However, this charging method will be slower than slow charging piles.
