What s the deal with electric cars that can t be charged?

The reasons why the tram cannot be charged are as follows:

1. There is a problem with the charger, there is no current in the input and output of the charger, the internal circuit of the circuit board is in poor contact, the fuse is broken, the water is short-circuited, the charger plug and power socket are not in place, etc.

2. The battery is aging, water loss, line disconnection, battery short circuit, battery bulging, voltage is too low, and the plates inside the battery are broken, etc., which will cause the battery to be unable to be charged. Repair solution or distilled water can be supplemented.

Causes and solutions:

1. At the end of the battery life, replace or repair the battery.

2. The fuse in the fuse tube in the battery is broken, and the fuse is replaced.

3. If the contact between the battery safety tube and the safety seat is not good, adjust the position of the two to make it in good contact, or replace the safety tube.

4. If there is no output voltage or the output voltage is low, replace or repair the charger.

5. The charger is in poor contact with the AC 220V power supply, please plug and unplug the power supply in time.

6. The charger indicator is abnormal, resulting in false fullness. Replace or repair the charger.

The reasons why electric vehicles cannot be charged are as follows:

1. Charger converter.

or the insurance is damaged, resulting in the electric vehicle charging has been green light and cannot be charged. The correct solution is to replace the converter or insurance, but if it still can't be solved, the only option is to replace it with a new charger.

2. A small battery in the battery pack is faulty, resulting in the electric vehicle charging has been green light and cannot be charged. The correct solution is to let the maintenance master use a multimeter.

Check whether each battery is faulty, find the faulty battery, and see if it can be repaired, but if it can't be repaired, you can only choose to replace it with a new battery.

3. The connection line has fallen off or is connected virtually, resulting in the electric vehicle charging has been green and cannot be charged.

The aspect that needs to be considered is whether the connection line is falling off or being falsely connected, which is generally manifested as a loose or corroded interface with a false connection. The correct solution is to reseat the charger and see if it jumps from green to red, if not, then you need to check whether the interface is corroded, and if so, you need to replace the wiring again.

An electric car does not charge up.

Reasons why the electric vehicle cannot be charged: 1. Battery life: The battery may be scrapped in advance due to incorrect charging methods, so when it is found that the battery cannot be charged, it is necessary to go to the electric vehicle maintenance shop to check it and replace or repair it in time; 2. The fuse is broken

If the fuse inside the electric switch is broken, it will not be energized; 3. Poor contact: When the contact between the fuse tube and the fuse seat, the poor contact between the charger and the power supply, and the poor contact between the plug and socket, it will affect the normal charging of the electric vehicle, resulting in the battery not being charged or not being fully charged. The charger itself will also age, especially some cheap products, the electronic components are unstable, and a certain component may be burned out after a period of use, resulting in abnormal output voltage, or the lamp cannot be turned, in this case, you can find someone who repairs the appliance to repair, or directly replace it with a new one.

The first condition to be met is the matching of the charging cable and the charging interface, that is, the physical connection. If the charging cable can be plugged into the car normally, the basis for charging is established. Low-voltage auxiliary power-on is the process of powering on the BMS of the vehicle, and the BMS can further shake hands and communicate with the charging pile when the BMS is energized, that is, confirm the version with each other.

If the version is the same, the BMS will send detailed vehicle information and exchange information with the charging station. During the charging process of the wide limb car, a large number of messages will be generated between the two, and if there is a mismatch, the normal charging work cannot be completed.

1. The three core components of electric vehicles. Batteries, controllers, motors. When making finished products from electric vehicles, we try not to modify them privately, such as installing battery packs, the current and voltage of the controller and motor are not working within their normal range, which will affect their life.

2. When charging, the output should be connected to the electric vehicle first, and then the plug should be plugged into the power supply. And vice versa, unplug the power supply and then the output connector when charging is complete.

3. The charging time for the battery is generally 8-10 hours. Based on the electric vehicle charger charging for 2 hours after the green light is on, the first electric car can be charged for an additional 2 hours after the power is exhausted.

4. It is best not to slam the "accelerator" when the electric car starts. One is because the instantaneous current is too large and easy to cause accidents, and the other is that the excessive loss of power also damages the battery, the electric vehicle should not wait until the last point of power is exhausted and then charged, the standard of measurement is 30% of the total power, and do not run out of power to force the electric car, the battery is damaged.

5. Electric vehicle braking method. The braking sequence should be the front brake after the brake, the situation is urgent, do not brake suddenly, hold the brake lightly little by little, especially in the case of disc brakes, after all, the electric car is two-wheeled, and the sudden braking will lead to the irregular swing of the electric vehicle is very easy to cause safety accidents. In addition, grinding tires will also greatly reduce the life of tires.

1. The line in the battery is short-circuited and the fuse is blown, and the solution is to replace the battery fuse with a new fuse.

2. The internal circuit of the power display screen is broken, and the solution is to send the power display for repair, or the instrument circuit board to repair.

3. If the charger is faulty or damaged, the solution is to send the charger for repair, or directly replace the charger with a new one.

4. The charger indicator is faulty. Solution: Send the charger for repair, or replace it with a new one.

5. If the charger is in poor contact with the power supply, the solution is to reconnect the power cord with the charger.

6. If the contact of the fuse tube in the battery is poor, the solution is to manually adjust the fuse tube until the contact is good, or replace it with a new fuse.

7. The battery life expires and stops working, and the solution is to replace the new battery directly.

The reasons why electric vehicles cannot be charged are as follows:

1. The line in the battery is short-circuited and the fuse is blown, and the solution is to replace the battery fuse with a new fuse.

Electric vehicle batteries.

Reasons and solutions for not being able to charge up:

1. The battery is up to life. Generally speaking, the service life of the battery is 3-5 years, but it is also possible that the battery will be scrapped early due to incorrect charging methods. Therefore, when you find that the battery cannot be charged, you should go to the electric vehicle repair shop to check it and replace or repair it in time.

2. a fuse.

Broken as everyone knows, the electric switch.

If the fuse inside is broken, it will definitely not be energized. In the same way, if the fuse inside the battery is broken, of course, it will not be charged. At this time, what you have to do is to go to the specialty store to replace the fuse, and don't mess around with it yourself.

3. Poor contact. When the contact between the fuse tube and the fuse seat is poor, when the charger and the power supply are in poor contact, and when the plug and socket are in poor contact, it will affect the normal charging of the electric vehicle, resulting in the battery not being charged or not being fully charged.

4. There is a problem with the positive and negative poles. According to professionals, poor contact of the plug-in in the battery or broken leads can also lead to no voltage. Whether the connection between the positive and negative poles of the dial is normal also has a great impact on the electric vehicle battery, and it can be handled by re-plugging or changing the wire.

5. Circuit breaking. When the circuit board in the watch face is broken, it is very normal for the battery to be undercharged or not charged. At this time, what needs to be done is to replace or repair the circuit board to ensure that the contact is normal.

The reasons why electric vehicles cannot be charged are as follows:

1. The service life of the electric vehicle battery expires

Most of the electric vehicle batteries use lead-acid batteries as the power heart, and the service life of lead-acid batteries is mostly about 3 years.

In addition to the quality of the battery itself, it also has a very close relationship with the rider's usage habits, the degree of overcharge, the frequency of discharge, the acceleration of riding, the parking position of the electric vehicle, etc., so when the electric vehicle battery cannot be charged, we need to judge whether the battery life is expired.

2. The charger is faulty

Charger failure is also a common cause of electric vehicle battery failure to charge, especially in windy and rainy days.

When the light on the charger is not lit when the charger is plugged in to connect the battery, then it may be the fault of the charger, or when the light on the charger is green, it may also be a problem with the charger, then you need to find a new charger with the same power to try to connect, if the new charger can charge normally, then it can be determined that the original charger is faulty.

Precautions for EV charging.

1. Electric vehicles do not need to be charged regularly for long-term storage.

If the electric car is not used for a long time, it is necessary to charge the electric car, and it can be charged once every ten days and half a month, because the battery itself will be discharged, so do not place it in the case of power loss;

2. Charge in time, and the charging time is at least 1 hour.

When charging, in order to keep the battery safe, pay attention to charging at any time, when there is no power, try not to use it, when the charging indicator light is on, it is best to charge for one hour.

If the electric vehicle cannot be charged, we must first check whether the charger and charging cable are normal, and first rule out the problem of the charger and cable!

Go to the after-sales service to check, if the charger is fine, it is a problem with the battery car line.

The reasons why electric vehicles cannot be charged are as follows:

1. The line in the battery is short-circuited and the fuse is blown, and the solution is to replace the battery fuse with a new fuse.

2. The internal circuit of the power display screen is broken, and the solution is to send the power display for repair, or the instrument circuit board to repair.

3. If the charger is faulty or damaged, the solution is to send the charger for repair, or directly replace the charger with a new one;

4. The charger Qimingxun indicator is faulty. Solution: Send the charger for repair, or replace it with a new one.

5. If the charger is in poor contact with the power supply, the solution is to reconnect the power cord with the charger.

6. If the contact of the fuse tube in the battery is poor, the solution is to manually adjust the fuse tube to good contact, or replace it with a new fuse tube;

7. The battery life expires and stops working, and the solution is to replace the new battery directly.

The following reasons are the reasons why electric vehicles cannot be charged:

1. Check whether the circuit connection is in good contact and whether the charger is mixed.

When charging, check whether the socket and charging cable are working normally to avoid the situation that the charger cannot be charged due to socket failure and looseness. When charging, the charger type adapted to the electric vehicle itself should be used to avoid using the charger of other models and models, and the charging will be invalid.

2. The plates inside a certain battery are broken.

For lead-acid battery packs, if the charger and battery wiring are normal but cannot be charged, there is no doubt that the plates inside a battery are broken.

3. The battery is seriously bulging, resulting in the electric vehicle not being charged.

4. If the battery is left for too long, the voltage is too low and the charger cannot be charged.

The battery will not be used for a long time, and the battery will receive great damage from the inclusions, and it is common for the battery to enter a dormant state, so that it cannot be used normally, or more seriously, the battery liquid inside the battery will dry up. For such cases, the easiest way is to try to charge with a low-model charger first, and then change to the charger from the original liquid after the voltage comes up. Old scum.

It is best to find a maintenance point for repairs related to electric vehicles, do not disassemble the internal components without permission, and regularly overhaul the battery.
