Does EV charging affect the battery if the charger is not unplugged?

Influential. When charging lead-acid power batteries for electric vehicles, the green light is generally used as a sign of full charge, but the charging is not stopped after turning the green light, but it is only transferred to the next stage of trickle charging, and it is generally recommended to turn off the power for about 2 hours after trickle charging, which will be beneficial to the life of the battery pack.

The charger of lead-acid batteries for electric vehicles generally has a three-stage charging mode, including:

1) The first stage is constant current voltage limiting, such as charging a 6020 battery, the current value is generally 3A, and the voltage limiting value is 74V.

2) The second stage is constant voltage current limiting, until the current drops to the current value of the jumping lamp and turns to the next step, the constant voltage 74V current limiting 3A, until the current drops to the jumping lamp.

3) The third stage is trickle floating charge, also known as maintenance charging, floating charge voltage 69V current limit, this stage is generally 2 3 hours after the power off.

Please refer to the following for charging and discharging:

1) When 100% of the electricity is used up, the general charging time will be 8 10 hours, do not exceed 12 hours (will have an impact on the battery life), it is not recommended to use up the electricity every time you use it, it is generally recommended to charge it at about 70%, and the charging time is 6 to 8 hours.

2) If the short-range user is recommended to charge in the following way: when the daily power consumption is 10%, it can be charged once a week; When the daily electricity consumption is 20%, it can be charged once every three days; When the daily electricity consumption is 30%, it can be charged once every two days; When the daily electricity consumption is more than 40%, it can be charged once a day, and the charging time is controlled, generally about 6 hours.

After the battery car is fully charged, the consequences of not pulling out the charger are as follows:

1. Reduce battery life: Generally speaking, the electric vehicle charger can be charged for 1 to 2 hours after turning green, and the charging time is usually controlled at 8 to 10 hours, and should not exceed 12 hours. If you charge it overnight, then the charging time is much more than 12 hours.

Overcharging an EV battery can cause a large amount of gas to wash over the battery's plates, causing the active material to fall off and ultimately reducing the battery's lifespan.

2. Battery hot and swollen: Overcharging of the electric vehicle battery will lead to faster water loss, which will affect the decomposition of the electrolyte and cause the battery to be hot and swollen. Especially in high temperature weather, it is necessary to avoid overcharging, if overcharging in a high temperature environment, it is easy to cause spontaneous combustion of electric vehicles.

3. Reduce the performance of the charger: there are many components inside the electric vehicle charger, if the electric vehicle is charged for a long time, the charger will always be in the state of accessing the current, and the internal components at this time will gradually heat up, and the accumulation of a long time will accelerate the aging rate of the components, so that the performance of the charger will decrease, thereby affecting its life.

Fourth, the battery life becomes shorter: the battery can be said to be the heart of the electric vehicle, and overcharging the electric vehicle will accelerate the aging rate of the battery, thereby reducing the mileage of the electric vehicle.

5. Cause fire: If the charging time of electric vehicles is too long, it will lead to spontaneous combustion of the battery, which will cause a fire. In recent years, electric vehicle fires have shown a year-by-year growth trend, causing huge losses to the personal and property safety of citizens, and have become a prominent problem that seriously affects fire safety.

According to incomplete statistics, 80% of the fires caused by electric vehicles occur when charging at night, so it is very important to charge electric vehicles safely.

6. Increase power consumption: Although the power required for a full charge of an electric vehicle is not much, if the charger is not unplugged for a long time, the power loss in a year is also quite a lot. Therefore, electric vehicle users should pay attention to the charging time of electric vehicles, charge them reasonably, and avoid unnecessary waste of resources.

Impact 1: Accelerate the aging rate of the internal components of the charger, so that the performance of the charger decreases;

Impact 2: Overcharge the battery and shorten its service life;

Impact 3: The battery temperature is too high, which is easy to cause**;

Impact 4: Increase power consumption.

Therefore, it is still necessary to unplug the charger in time.

It should be after turning the lights.

2. Unplug the charger for three hours.

<> if you do not unplug the charger every time it is fully charged, it may damage the battery first, that is, reduce the service life of the battery.

Secondly, it will also have an impact on the charger, it may form a long-term supply of current, and it has been in the phenomenon of too high temperature, if the harm is slight, it may cause the charger to accumulate dirt or burn out the internal wire, resulting in damage to the charger, if the harm is serious, a fire may occur, this situation is very dangerous, so it is recommended to unplug the charger after it is fully charged.

Roughly speaking, the electric vehicle battery must be unplugged when fully charged, you can learn to control the charging time, friends must know that the electric car is fully charged after the prompt light will definitely change from red to green, this is the most intuitive way to check the power, and you can charge according to the season, in winter, you can control the time in about 8 hours, because the temperature is low, will not hinder the life of the battery, in the summer, you can charge for about 6 hours, Try to charge it in a cool place, and it can also protect the battery well at this time.

That is to say, these two time periods can be fully charged under the condition of protecting the battery, and will not form the uncertainty and difficulty of controlling the time, according to this method, the battery can be used for several years, of course, the battery is also a consumable, and the battery must be replaced at a certain time.

Of course, this is possible, there is no problem, but it is more power-intensive. Because you don't unplug the charger. Then the charger is in standby case, which consumes more electricity.

Under normal circumstances, it doesn't matter much if you don't pull out the gun in time after it is fully charged. Because the BMS at the end of the car will control the charging current, when the vehicle is fully charged, the BMS will send a "stop charging" signal, at this time the charging pile is actually in a closed state, at this time it is okay not to pull out the gun in time, the charging gun continues to be plugged in the car end, there will be no damage to the battery or the vehicle.

The electric car is fully charged and does not dial the charger has an impact on the battery. Most of the batteries in electric vehicles are lead-acid batteries. Overcharging will increase the water loss of the battery, accelerate the corrosion of the grid, soften the active material, and increase the probability of battery deformation.

It's best not to do this, as it may be a safety hazard or bad for the battery. You can buy a timer, so it's perfect.

Glad to have your questions from me, as mine was helpful to you, hope, thank you!

If the electric vehicle battery is fully charged and does not pull out the charger, it will have a certain impact on the battery and the charger, and the specific analysis is as follows:

1. Accelerate the aging speed of the internal components of the charger and reduce the performance of the charger: We all know that there are many components inside the electric vehicle charger, and if the charger is not pulled out for a long time, the charger will always be in the state of connecting current. At this time, the internal components will gradually heat up, and the accumulation of a long time will accelerate the aging rate of the components, reduce the performance of the charger, and affect its life.

2. Overcharge the battery and shorten its service life: Although many chargers now have charging protection, even so, if the charger is not pulled out for a long time after being fully charged, there will be a weak current and then continue to charge, which will cause some damage to the battery. The accumulation of a long time will overcharge the battery and shorten its service life.

3. Aggravate safety risks: electric vehicle chargers will continue to heat up in the power-on state, and now that the temperature is rising, if the electric vehicle is charged in a closed environment, it is likely to burn the charger and even the electric vehicle, thus causing new safety risks.

4. Increase power consumption: Although the power required for a full charge of an electric vehicle is not much, the power lost in a year is also quite a lot if the charger is not pulled out for a long time.

Hello Glad for your question accelerates the aging rate of the internal components of the charger and degrades the performance of the charger. Shorten the life of the battery.

There is also an increase in electricity consumption.

Questions. Is it okay to pull out the battery when the battery car is fully charged and the charger is not unplugged?

Therefore, we should unplug the charger in time during daily charging, which can not only protect the charger, but also prolong the battery life.

Hello It's okay for a short time, no impact. But over time, it will definitely have an effect. It is recommended that you still develop good charging habits.

After the battery car is fully charged, not pulling out the charger has an impact.

If the battery car is fully charged, if the charger is not pulled, the internal components of the charger will be damaged, and the battery performance will be reduced; If the battery is overcharged, it will shorten the service life; The charger should be unplugged in time to protect the charger and prolong the battery life.

Electric vehicles are a common means of travel, and their structure is very simple. The key components of an electric vehicle include the frame, motor, battery, and regulator.

The electric vehicle is fully charged and does not pull out the battery, occasionally once or twice has little impact on the battery, which will lead to the change of the original capacitance of the battery for a long time, and accelerate the aging and service life of the battery, so be sure to follow the instructions of the manual, until the battery is fully charged and then disconnect the power supply.

When charging lead-acid power batteries for electric vehicles, the green light is generally used as a sign of full charge, but the charging is not stopped after turning the green light, but it is only transferred to the next stage of trickle charging, and it is generally recommended to turn off the power for about 2 hours after trickle charging, which will be beneficial to the life of the battery pack.

Influential. If the charger is fully charged, the charger will still continuously deliver a weak current to the battery, which is what we often call a floating charge. Although a short period of floating charge is beneficial for the battery to be fully charged, if it is floated for a long time, then it will accelerate the rate of battery water loss, which will accelerate the aging rate of the battery, or even directly charge, thereby shortening the battery life.

If the charger is fully charged, the temperature of the charger will rise, and the loss of the internal components of the charger will be accelerated, and once it is operated for a long time, the aging speed of the components will be accelerated, and then the parameters of the charger will be offset, so that the charging efficiency and life of the charger will decrease, or even be scrapped directly.

It doesn't matter, when the electric vehicle is not enough, it often needs to be charged for a short time, and it doesn't matter if it is not fully unplugged, but don't do it every time, most of the time it is better to charge it full, otherwise it will affect the service life of the battery.

There is no harm, but such a way of charging is not recommended. 1. Continue to charge after the battery car is fully charged, and the charging device will also charge the battery, but the charging device has a protection device, and the main charging device will be automatically disconnected after being fully charged, and it will enter the floating charging state. Second, the so-called floating charge, is to use a small current to continue charging the battery after the battery is fully charged, at this time it is called floating charge, also known as trickle charging.

The small current is generally not set artificially, but after the voltage is set to the floating charge voltage (for example, in the case of a 12V battery, the float charge voltage is within the range), the battery is fully charged, and the acceptable current is very small, and the floating charge current is automatically formed. 3. There are three purposes of floating charge: to keep the voltage of the battery in the range of floating charge voltage, at this time, the corrosion of the battery grid (that is, the conductive skeleton of the plate) is in the slowest state, which can prolong the battery life.

Replenish the capacity loss caused by the self-discharge of the battery and keep the power sufficient. Inhibits sulfation caused by recrystallization of active substances. We hope you find it helpful

Yes. Generally speaking, the number of complete charge and discharge times of lead-acid batteries is about 360 times, while the number of complete charge and discharge times of lithium batteries is about 520 times. Therefore, if you unplug the charger before it is fully charged, it will consume the number of charge and discharge times prematurely, and its life will be reduced.

For example, if an electric vehicle battery that could have been used for 3 years is often unplugged before it is fully charged, it may be able to last for 2 years, or even less.

When an electric vehicle is charging, it releases a lot of heat, and the internal temperature of the battery also rises. If you unplug the charger before it is fully charged, and ride it directly, the temperature of the originally high temperature battery will become even higher. At this time, the battery will lose water faster, thereby accelerating the aging rate of the battery and affecting its service life.

It will have an impact on the battery capacity, the battery has a memory effect, and if it is not fully charged for a long time, the battery capacity will decrease, but if you can perform a deep discharge (to 20%) on the battery every other month, and then fully charge, it will be good for the battery to return to normal.
