To charge the battery of an electric vehicle, should I connect the battery or the power socket first

Electric vehicles as one of the most popular traffic workers, with more than 300 million car owners to choose, however, the real maintenance of electric vehicles is not much, electric vehicles because of the cheap, the cost of replacement is relatively low, many people are difficult to have the patience to learn and standardize the maintenance habits of electric vehicles, but, as everyone knows, you can change the charging method at will, so that the battery life is longer, for example, to charge the electric vehicle battery, whether to connect the battery or the power socket first, I believe many car owners are not clear.

When charging, most of them are more casual, first connect the battery and first connect the socket, however, if the first battery is actually a more accurate way, I believe that many car owners have been doing wrong, so why, let's take a look at the reason.

One: It can protect the chargerWhen the charger of the electric vehicle is charging, if it is plugged in the power supply first, it will form an instantaneous large current, and at this time the battery has not been plugged in, which will cause the charger to be impacted by the high current, resulting in the aging of the charger, and even scrapping.

Two: It can reduce the damage to the batteryThe number of times the lead-acid battery is completely charged and discharged is only about 350 times, if the power supply is connected first and then the battery, it will accelerate the water loss rate of the electric vehicle battery because of the surge impulse current formed in the charger, and once the battery loses water, it will appear bulging, not durable, and even the battery life will not work until it is scrapped, so choose the right charging method, not only can protect the charger but also play a role in protecting the battery.

Three: It can reduce potential safety hazardsEvery year, there are not a few potential safety hazards caused by electric vehicle charging in China, and most of the reasons are the use of the wrong charging method, and the first power supply and then the battery is a very wrong way, so that if the charger has a fault or quality problems, it can not withstand the impact of instantaneous high current, which will cause the risk of spontaneous combustion.

Therefore, whether it is from the perspective of protecting the battery and the charger, but also from the perspective of safety, the electric vehicle should be plugged in first and then connected to the power supply when charging, which can not only ensure the service life of the battery and the charger, but also ensure our charging safety.

I think it is necessary to connect the power socket first, because you have to plug in the socket before you can charge it into the battery.

To charge the battery of an electric vehicle, it is the correct process to connect the battery first, so as to avoid the possibility of electric shock.

Connect the battery first, because I think it's safer to operate.

Connect the battery first, then the power supply. If you do this, the charger will light up red first, not green first. At this time, the electric vehicle charger will enter the soft start state, the current will be relatively stable and will not form a surge impulse current, and the impact on the battery and charger will be lower, and the life of the battery and charger will be extended to the greatest extent.

Note. Connect the power supply first, then the battery. If you do this, the charger will first jump the green light and then turn the red light. At this time, the instantaneous current will rise rapidly, forming a surge impulse current, which will accelerate the aging and water loss rate of the battery, and reduce its lifespan.

In addition, the inrush current will also cause an impact on the charger, which is easy to offset its parameters during long-term operation, shorten the service life of the charger, or even directly charge the charger.

When charging the EV charger, first plug the charger output into the EV socket, and then plug the charger input into the 220V AC power socket. After fully charging, first unplug the 220V AC power plug, and then unplug the electric vehicle end. The good thing is that it's safe and the charger isn't easy to break.

It would be better to plug it in first, because that would prevent it from suddenly increasing current.

EV charging, plug in the car or plug in the power first? I finally understand it today, so let's take a look.

Plug in the battery car first, and unplug the power supply first.

The charging time of electric vehicles depends on what type of battery your car is used and how large the capacity of the battery is, the general fast charging of electric vehicles takes 30 minutes to charge 50% of the charge, and it is fully charged in 1 hour, and the slow charging takes about 6 to 12 hours.

The first charging time of the electric vehicle, because the battery car battery has not been used when it leaves the factory, has not experienced charging and discharging, and it is necessary to ensure the normal operation of the battery. Under normal circumstances, the charging time is about 5-6 hours, so that the battery can be fully charged, and then the use can be slightly longer. Charging during the day allows you to better control the time.

Hello:——1. From a safety point of view, you should plug in the battery car first and plug in the power plug after charging.

2. At the end of charging, you should unplug the power plug first, and then pull out the battery car plug after the power is off.

3. When charging, the battery car should be plugged in first, and the power plug should be plugged in later, which can reduce the impact of current (the role of power filter capacitor).

4. Unplug the power plug at the end of charging, which can make the charger high voltage disappear quickly and make it more reasonable to use.

This is a safe electricity issue, plug in the battery first when charging, then plug in the power supply, after charging, first unplug the power supply and then pull the battery wire.

Unplug the power connector first, remember to turn off the power of the car when charging, so that you can better protect the battery.

When charging, plug in the body first and plug in the power supply, and then take the power supply and then take the body. Professional guidance.

Plug in the battery car first, then plug in the power supply; Unplug the power supply first, then unplug the battery car.

Plug in the battery first, put the power first, the battery and your life is safe.

Charge first and plug it in. Pull out the battery car first.

This needs to be explained from the most fundamental operating principle of the charger.

In order to accurately provide the charging state of the battery, such as constant current charging or constant voltage charging, the charger must detect the voltage of the battery at that time and control it, and even detect that the battery is full, it needs to control and stop charging, and so on.

When the charger is connected to the power supply first, and is not connected to the charged object - the battery, because the corresponding voltage signal cannot be detected, the charger control is purposeless, and the output voltage is arbitrary value. The output voltage is too high or too low will have a certain impact on the battery, but under normal circumstances, this effect is very small, but in extreme cases, such as the extreme lack of power and extreme sufficiency of the battery. At this point, the extreme output of the charger may become the "last straw" that crushes the battery.

In order to prevent the charger from burning out the charger at no load, the charger needs to be connected to the tram battery first and then connected to the 220V power supply.

When fully charged, the charger needs to be disconnected from the power supply first, and then disconnected from the battery.

Answer, why plug in the electric vehicle battery charging port first when charging the electric vehicle, that is because the charging port is not fully discharged, the three internal plug heads are electrified, so the battery charging port has a small cover wrench, that is, to prevent electric shock, and the first plug in the charging port is also to prevent leakage ** flower hurt, so it is connected to the 22ov power supply.

Plug in the battery charging terminal first, and then plug in the AC terminal, which is to connect the load end of the charger to avoid the impact of no-load high-voltage load, in case of leakage, because it has been plugged in, it is also safe.

When removing the charger, the operation is just the opposite, first unplugging the AC terminal and then the charging terminal, for the same reason.

To charge an electric car, plug it in first or an electrical outlet? Many people do something wrong and regret it.

When the battery car is charging, plug in the charger first and then plug in the power supply, and when fully charged, first dial the power supply before disconnecting the charger, please do not connect the power supply before plugging in the charger.

There is basically no order.

EV charging is to plug in the charger first.

There are two main principles to grasp in the correct charging of electric vehicles: one is to charge shallowly. Second, it cannot be overcharged.

1. Lead sulfate is formed when the battery is discharged, and lead sulfate is reduced to sulfuric acid and lead during charging. If it is deeply discharged or not charged in time, the lead sulfate cannot be reduced, resulting in vulcanization of the plates. Therefore, it should be ridden every day, charged every day, and not deeply discharged.

2. If the charging time is too long, the water in the battery will be consumed excessively, and the vulcanization process of the plate will be accelerated, so that the capacity of the battery will gradually decrease due to lack of water, until the battery is charged and scrapped.
