Is it normal for the charger light to turn off after the EV charger is fully charged?

It's a bit out of order. The general charger should have two indicators, the red light is the power on indicator, and the other is the green light for the battery full indicator.

The charger will generally be marked with charging at the red light and full at the green light. This means that when the two lights are on, the battery level will be different.

If the charger can't light up the green light after it is fully charged, you can check whether the green light is good. If the green light is normal, it should be a problem with the charger's detection and sensing circuit, which cannot sense that the battery is fully charged.

If you confirm that the light is off, it is fully charged, and you can continue to use it, or you can change the charger to charge it.

Whether it is normal for the EV charger to turn off the indicator light after it is fully charged depends on the form of the charger. If it is a charger with only one indicator light, the indicator light is on when charging, turns off when fully charged, and can be charged normally, it is normal. If it is a charger with red and green lights, it is possible that the red light is on when charging, and the green light is on when it is fully charged.

In any case, it is normal to be able to fully charge the battery, and it is not normal to be fully charged.

If the charger can be recharged and can be charged normally, it means that it is normal for the light to go out, most chargers will not turn off the light after being fully charged, but some chargers are designed to automatically power off function, and the power will be completely cut off about an hour after being fully charged, the light is off, and you can start charging again by plugging in and unplugging the power supply.

It must be abnormal, even if the charger is fully charged with the battery, it should also be displayed, for example, if the green light is displayed, then if any light is not displayed at this time, either the charger is faulty, or the light is broken.

It stands to reason that it is abnormal, after the charger is fully charged, it should change the light, from a red light to a green light. I haven't seen the lights go out when it's fully charged.

Charging on the community charging pile is automatically powered off after being fully charged, and the charger will be turned off at the same time!! If the electricity is on, the lights will not go out.

The manufacturers of this charger are all different, and some will turn off the light after an hour of full charge, which is also to protect your battery, and it must not be charged continuously.

Summary. Hello, I am happy to answer your car master exclusive technician to answer your car questions sincerely and sincerely for you, and find solutions and methods for you to ask questions. After the charger of the electric vehicle is fully charged, the indicator light of the charger will go out, which is different according to the charger settings, some chargers will charge, the indicator light will become green, and it will be always on, and some will be charged off.

You can charge it a few times first, if the battery can be fully charged, and the charging light will go off every time you charge it later, the charger is set like this, which is normal. Hope mine is helpful to you.

Is it normal for the charger light to turn off after the EV charger is fully charged?

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I am glad to answer your car master exclusive technician Concentrate on your heart Lu Zhaoxin to answer your car questions and find solutions and methods for you.

Hope mine is helpful to you.

Cause of failure:

1. Battery failure. When the final voltage of the battery is lower than the rated final voltage, the charger always detects that it is not fully charged, so the charging does not stop.

2. The charger is faulty. When the actual output voltage of the charger is higher than the rated output voltage, there will also be a non-stop charging failure.

Notes:

1: 48V new battery requires charger parameters, the highest voltage, not less than 58V, lower than 58V to cause insufficient charging, higher than may cause charging without turning the light. The current of the turning lamp is about, the actual voltage is about, and the charging is insufficient if it is lower than 50V, and the battery is lost for a long time.

2: 4820 battery requires the maximum current of charging, lower than the charging slow, poor charging effect, 3: the actual power of the charger below 30 yuan on the market is small, the parameter design is not accurate, please pay attention to the distinction.

4: The failure of the charger regulator circuit will cause the output voltage to be 75---130V, and the rechargeable battery will not turn the lamp if it is hot.

5: When the new battery appears, the mileage of the 20A battery is less than 30 kilometers 12A battery is less than 25 kilometers, please check the parameters of the charger, if you can't judge it, please replace the high-quality charger and use it again, you can solve the problem.

6: When the new battery does not turn the light, please replace it with another high-quality charger for testing, 7: Under normal circumstances. The charging time of the 4820 new battery is about 10 hours, the cruising range is 40---60 kilometers, the charging time of the 4812 new battery is about 10 hours, and the mileage reaches 25---40 kilometers.

8: There are many chargers with aging internal circuits and input and output wiring, resulting in sometimes being able to charge and sometimes not being able to flush. Seriously affect the battery, or the circuit fails during the charging process, resulting in a bulging bag, if this happens, please directly replace the high-quality electrical appliances and use them again.

You mean. Ask about electric car charging.

After a full charge. The charger is two lights from the light.

What's going on when the movement goes out? This.

kind of situation. That's generally the main reason why the charger is broken.

There is a charger that automatically turns off the power, and when it is fully charged, it turns off the lights by itself, and the next time you use it, you may have to wake up for a while, because I have a charger like this.

The light of the charger will not go off, at this time the red light of the original charging indication should be converted to a green light Hello, the electric car charger after the battery is fully charged. The red light of the power indicator should be constant.

An electric car charger is a charging device specially configured for the battery of an electric bicycle! Classification of chargers: With and without power frequency (50 Hz) transformers, it can be divided into two categories.

Freight three-wheel chargers generally use chargers with power frequency transformers, which are large, heavy and power-intensive, but reliable and cheap.

The correct operation of a switching power charger is:

When charging, plug in the battery first, and then add the mains; When sufficient, cut off the mains power first, and then unplug the battery. If you unplug the battery first while charging, especially when the charging current is high (red light), it is very easy to damage the charger.

The commonly used switching power supply chargers are divided into two categories: half-bridge and single-excitation, and single-excitation is divided into two categories: forward and flyback. The half-bridge type has high cost and good performance, and is often used in chargers with negative pulses; The single-excitation type has a low cost and a high market share.

Hello, the light of the charger will not go off after the battery is fully charged in the EV charger. The red light of the power indication should be constant, and the red light of the original charging indication should be converted to a green light. For your reference.

Hello: The charger of the electric vehicle will not turn off after the battery is fully charged, and will generally change from red to green.

Summary. Hello, the electric car charger will automatically power off after it is fully charged, but this green light is still lit all the time, which is a normal state.

First, the power is automatically cut off, but the vehicle's charger is still connected to the normal 220 volt power supply, so there is a relevant green light indication.

Second, this power-off belongs to the internal disconnection of the charger to charge the vehicle battery, and this related current.

Third, this is a normal phenomenon, so you can rest assured.

The electric vehicle charger is fully charged and automatically powered off, why does the green light stay on after it is fully charged?

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello, the electric car charger will automatically power off after it is fully charged, but this green light is still lit all the time, which is a normal state. First, the power is automatically cut off, but the charger of the vehicle is still connected to the normal 220 volt power supply, so there is a relevant green light indication. Second, this power-off belongs to the internal disconnection of the charger to charge the vehicle battery, and this related current.

Third, this is a normal phenomenon, so you can rest assured.

After the charge is full, the power is not interrupted, however, it is a green light.

This green light is displayed all the time, which is normal.

One of the batteries in the battery pack was delayed and was short-circuited, causing the charger to display a red light all the time.

If one of the small batteries in the battery pack is short-circuited, it will not function properly when the EV is charging, causing the charger to display a red light all the time. In this case, users can use a multimeter first.

The voltage of each small battery is tested, and the one with the lowest voltage display is the short-circuited battery.

For this situation, there are generally two solutions, the first is to rematch, and the second is to replace the new battery, so as to solve the problem that the charging Nadanzen electrical appliance has been showing a red light.

Precautions for the use of electric vehicle chargers.

If you are charging directly in the car, please disconnect the power lock switch on the electric vehicle, and first insert the charger output plug into the charging socket on the battery box, and then insert the charger input power plug into the AC 220V power outlet.

The working environment temperature of the charger should be about 25, not more than 30.

The charger should be moisture-proof and moisture-proof during use, and placed in a well-ventilated place. The charger cannot be used for long-term work or storage in a humid environment, let alone water ingress.

First, the electric vehicle charger charging and burial shed is not satisfied with the red light, which may be caused by the battery for a long time and the aging of the battery. It's best to replace the battery. Niwa Sakura, the charger current detection circuit is faulty. It is easy to judge by bending, so try it with a different charger.

1. The indicator light is not in good contact, 2. The charger is broken. After excluding poor contact, there is only the replacement of the charger, the charger is not recommended to be repaired, the maintenance cost is not much more than buying a new charger, it is better to buy a new cost-effective, and there is quality assurance.

When the charger starts to charge the battery, the current is relatively large (friends who have been careful observation should have such an experience, when the normal charging process, the temperature of the charger shell is relatively high, and the same is true for mobile phone chargers).

During the charging process, there is a sampling resistor at the output that feeds the sampled current back to the ICComparators, such as LM358 or 324, etc., after comparison, send a signal to control the red lightTransistors, the transistor is on, and the red light is on, indicating that it is in the process of charging.

When the battery is fully charged, the output current becomes smaller, the same way, the sampling resistor sends the sampling current signal to the comparator, and the comparator gives a signal to the green light of the control triode, the triode pipe is on, and the green light is on, indicating that the battery is full, and at the same time, the triode of the red light is cut off, and the red light is off.

The principle is like this, let's look at the problem again: the input line and the output head are fine, then there are only two possibilities:

The first one, the battery is broken, the battery is broken, the charging cannot be entered, the charging current is small, and the green light is naturally on. In this case, let's change the battery.

The second is that the charger is faulty, and there are many reasons for the charger failure, but the common one is the filter capacitor.

The capacity drops or fails, and in many cases, it cannot be measured, so the filter capacitor is replaced.

Then there is a problem with the current sampling resistance at the output end, this resistance is generally, about 2w, when the resistor is replaced, the resistance value can not be changed, and the power is better, as long as it can be installed.

There is a large capacity capacitor in the charger and power supply, the capacitor can store electric energy, and the electricity in the capacitor will also light up the indicator light on the power supply for a period of time after the power is off, and the length of time depends on the circuit design and the capacity of the capacitor. Some chargers are designed to light up the charger's green light when the battery is normally connected to the battery, turn red when plugged in and charge, and turn green when fully charged.

It depends on whether your charger has a voltage detection function, generally six lights or four lights have, you just plug in the charger to detect the voltage yourself, so the light is on, if there is no this function, the charger is broken.

If there is such a charger, as long as you connect the battery, the battery will light up the indicator, which is a design concept to tell you whether the plug is plugged in, of course, after the charging is completed, unplug the power supply without pulling out the charging port, this light will always be on.

The battery car charger disconnects the power supply and the light dims after a few seconds, it will not be like this, it will only light up after touching the power supply.
