The electric car is charged at night, but it doesn t go in the morning, the red light is on in the b

If your e-bike is charged at night, but you can't walk in the morning, and the red light is on in the back, and you stop and go, then your battery bike definitely hasn't been charged and entered, probably because.

1 There is a problem with the charger of your battery car, so it cannot be charged.

2 You didn't plug the charger in properly and it had poor contact, so it couldn't be charged.

3 There is a problem with the battery of your battery car, and no charge enters.

This situation should be that the power of your electric car is not fully charged at night, it may be that there is a problem with your electric car charger, you can change the charger to give it a try.

The power socket is not plugged in tightly, I have encountered it too, hope.

Check whether the battery output of the electric vehicle is normal, if the output is too low, it proves that the battery is bad and the battery needs to be replaced urgently;

2.Pull out the brake line, such as the car turning, proving that the brake handle is broken, hope

Hello. Are you sure you rushed in, you have to show that the light is on the red light is the charging state, of course, one walk and one stop is the line contact is poor or there is leakage.

If there is a problem with the brakes, check your brake grip and see if it is back in place.

This is because your electric car line is not in good contact...There was a short circuit problem. It is recommended that you find a place to repair it.

1.It wasn't charged at night, and the lights in the back kept on and discharged again. So it can't be opened in the morning.

Which side of the contact is not good, the line is loose, take it apart and see for yourself.

This should go to the car repair shop and let the car repairer see what the situation is, and don't go upside down.

Electric car charging keeps the red light, don't jump the green light what's going on:

1. A small battery in the battery pack of the electric vehicle fails, resulting in the electric vehicle charging without skipping the light.

Everyone knows that electric vehicle batteries are consumables, and problems will inevitably occur after long-term use. For example, when a small battery in the battery pack of an electric vehicle has a short circuit failure, charging the electric vehicle at this time, there will be a situation where the charging has not jumped the light, which is what we often call the situation of insufficient charging.

For this kind of problem, the general solution is to replace the entire group of batteries, so that the problem of charging without tripping lights can be solved. It is important to note here that you should not deliberately try to replace a small battery yourself, because the mismatch of the model may bring more new problems.

Second, the battery has a water loss failure, resulting in the electric vehicle charging has not jumped the light.

This situation is relatively common, generally if the electric vehicle battery is used for more than three years, many times there will be water loss failure. It is generally manifested as a serious heating of the battery during charging, and the charging does not jump the light. For such problems, it is generally impossible to solve them on their own.

You can go to the electric vehicle maintenance point and let the maintenance master test, if the water loss is not very serious, you can add water appropriately. But if the water loss is severe, then the only option is to replace the battery with a new one.

What to pay attention to when buying an electric car:

When buying an electric car, you need to pay attention to the electric vehicle's appearance, endurance, braking performance, battery performance, etc., as well as check whether the electric vehicle meets the national standards, whether it can be licensed, whether the electric vehicle has 3C compulsory certification, and how long the warranty period of the main components of the electric vehicle is, etc.

When buying an electric car, the first thing you see is the appearance of the tram, and when buying your favorite tram, you should pay attention to check whether there are defects in the paint and workmanship of the tram exterior.

Check the range of electric vehicles and choose the right range according to your travel needs. You can test ride the electric car you want to buy, check whether there is a problem with the braking performance, and experience whether the riding feeling is comfortable.

1. The charger is faulty, causing it to display a red light all the time: If the electric vehicle charger fails, it is generally manifested as the internal components falling off or being damaged, which will cause the charger to fail to jump the light normally, or even fail to charge, causing the charger to display a red light all the time. In this case, the only option is to replace the charger with a new one, rather than repairing it, because the charger is more troublesome to repair and it is more likely to cause problems again and cause the battery to overcharge.

2. There is a short circuit in one of the batteries in the battery pack, causing the charger to display a red light all the time: If one of the small batteries in the battery pack has a short circuit, then when the electric vehicle is charging, it will not be able to operate normally, resulting in the charger showing a red light all the time. In this case, the user 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 ways to solve it, the first is to re-match, and the second is to replace the battery with a new one, so as to solve the problem that the charger keeps showing a red light.

Hello, happy to answer your questions.

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. There are three reasons for this issue. ......The first reason is that the battery is damaged, there is a problem with the cell inside the battery, or the connection line is falsely connected, so it is necessary to disassemble the battery pack and check the cell.

If the voltage is found to be low, replace it in time. ......The second reason is that the charging current is insufficient due to a problem with the charger itself, or due to a damaged control board inside the charger. In this case, it is necessary to unplug the charger in time for testing, so as to avoid damage to the charger, which will cause the battery to be charged with a long-term high current, resulting in a shortened battery life.

The third reason is that the charger cannot get enough voltage to work normally due to the unstable voltage of the power supply or the voltage is insufficient. There is also a ,...... whether the grounding line of the power supply is normalCommon causes of this problem on the above three reasons, among which the possibility of battery damage is the largest, but also the easiest to eliminate, you can first let the master help you measure the battery voltage, or you have your own multimeter can also measure, if the voltage between the single battery appears above the voltage difference, replace the battery with a low voltage.

Questions. The charger shows a red light, but the battery cart shows that it is full, what is the reason?

Take the charger as the standard, don't look at the battery car, the battery car display is not accurate. When the voltage of the battery car is floating, the display is also full.

Questions. In this case, is the battery broken or the charger broken!

Both batteries and chargers are possible, but the most likely is the battery. In this case, you can use a multimeter to determine the problem, which is very simple and convenient.

Questions. Got it. Okay

As follows:

1. The charger is broken, when the charger can't be charged, but the indicator light is still on, it will mistakenly think that it has been charging, but in fact, it can't be charged at all.

2. Circuit board failure, when the circuit board in the dial is broken, it will also cause the battery to not be charged, as long as the circuit board is replaced or repaired.

3. Vulcanization of the battery plate, if the plate is vulcanized, the charge and discharge will show that the voltage rises quickly and the capacity is significantly reduced, so the sulfur should be removed with a repair instrument to restore the plate and restore its activity.

Note. 1. Avoid overcharging. When the charger shows that it is full, it will stop charging, and it cannot be charged overnight or even for days.

Overcharging will cause the active material of the plates to harden and fall off, and cause water loss and battery deformation. The battery runs in the high temperature season, and the main problem is overcharging. Therefore, in summer, the temperature of the battery should be reduced as much as possible to ensure good heat dissipation, prevent charging after exposure to the sun, and should be kept away from heat sources.

2. The battery is in the electric bicycle.

The upper installation should be firm. When the battery is taken down and charged, when installed, the battery should be installed firmly on the electric bicycle to prevent the battery from being damaged by vibration when riding. When the battery is transported, it is forbidden to throw, roll over, or weigh hard.

Electric car charging for one night, the next day shows no power, this situation may be your electric car charger is broken, should not be charged, you had better go to the electric car maintenance point to find the master to help see.

This should be a problem with your charger or battery, you can change the charger first, if not, you need to change the battery.

The most likely situation is that the plug is not plugged in properly when you charge, resulting in looseness, and it cannot be charged on the second day, but you should also check the specific reason.

It may be that there is a problem with the charger or the battery of the electric car, or it is better to go to the place where the electric car is repaired.

Either there is no power, or the charger is broken, or the battery is broken, go to a professional place to check it and see if you know.

Yes, the main reason is the charger, the internal converter of the charger is broken and cannot work properly, and a new charger needs to be replaced; Or it is caused by poor contact of the electric vehicle charging plug or charging interface.

Electric vehicles, i.e., electric vehicles, also known as electric vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Electric vehicles are vehicles that use batteries as energy sources to convert electrical energy into mechanical energy through controllers, motors and other components, thereby controlling current and changing speed.

If the car is still under repair, it is recommended to replace it with a new charger free of charge. If the warranty period is over, please disassemble the charger and let the moisture inside evaporate Try again. If it still doesn't work, you can only buy a charger.

It is recommended that electric vehicles be charged indoors as much as possible, not outdoors. Due to the weather, the charger is prone to moisture, so it is easy to break.

When the electric car charger is plugged in, the traffic lights are on, indicating that it cannot be charged at all.

There are four reasons why it can't be charged:

1. The charger is broken, you can try to change the charger.

2. The wiring inside the battery is disconnected.

3. The fuse on the battery connection line is broken.

4. The battery is broken.

Seriously aging or the plate is broken, depending on the situation, your battery has been swollen and changed, it is estimated that you will run 10 kilometers now, and the economy will be loosened in a few days, and it will not be repaired. It is best to limit the charging time to 8 hours, which can be stable and not deformed so .........

See if the battery is hot, if it is not hot, it can be repaired, and if it is hot, it can be replaced with a new one.

There are two reasons: one is the fault of the charger, which makes the battery not terminate the charging after charging to the specified voltage. One reason is the battery problem, one battery has a problem that cannot be charged to the specified voltage value, which drags down the entire battery pack.

If it is recommended to replace the charger and it still does not work, you can only replace the battery. Usually pay attention to maintenance, after riding the bike to charge in time, can not wait for the power to run out of recharge. If the battery loses power, it will shorten the service life of the battery.

Pay attention to the item of dismantling.

If the EV charger fails, it is generally manifested as the internal components falling off or being damaged, which will cause the charger to fail to jump the light normally, or even fail to charge, causing the charger to display a red light all the time. Round pants.

Hello for two reasons.

1. When the service life of the battery is up, the voltage drops more, and it cannot be charged, that is, it cannot be charged.

2. There is a problem with the charger, and it is not possible to carefully identify the change of the charging voltage of the chain, and the battery will be damaged due to easy wide selling.
