When the Jinhao electric vehicle charger is plugged in, the traffic light will be slightly bright, a

The electric vehicle charger is plugged into the electric element, the traffic lights are on, the fan does not rotate, and there is no output voltage.

The charger lights green, indicating that the EV's battery is fully charged. At this time, the charger is in a trickle-charging state. Basically, there is no power consumption. There is no need to protect the charger from heat dissipation. So the charger fan won't turn anymore.

1. The transistor is damaged.

The triode is to control the operation of the fan, and use a multimeter to measure the voltage at both ends of the trio to know whether it is damaged.

2. There is a problem with the fan itself.

Remove the fan from above and connect it to the 12V DC power supply, if it does not rotate, the fan is broken, otherwise it is not the problem of the fan.

3. The fan does not rotate when it rotates.

If the fan does not rotate when it is not turned, it may be caused by the false connection of the wire, just reconnect it. Method: First of all, use a multimeter to measure whether the triode of the lower control fan is damaged, if the tube is not damaged, then it may be that the fan itself is damaged, you can unplug the fan from the circuit board, and connect a 12V direct current (pay attention to the positive and negative poles) to see if it rotates, but also to see if there is a foreign object stuck.

If the fan rotates after a few swings of the fan's wire, it means that there is a broken wire inside the wire or the connector is not in good contact. If it still doesn't turn, the fan will break. For chargers with intelligent heat dissipation, in addition to the above checks, you should also check whether the thermistor is in poor contact or damaged, open welding, etc.

Have a great day!

The fan of the EV charger is a cooling component that prevents the charger from overheating during charging. Generally, the charger has a green light, indicating that the battery is fully charged and does not need to be cooled down, therefore, it no longer turns.

Two possibilities:

1. It is possible that your charging port cable is broken。Use a multimeter to test the charging port, whether there is voltage, if not, check whether the charging port cable is broken, just connect it.

Second, it is possible that the fuse at the output end of the charger is burned. Use a multimeter to test whether there is voltage at the output of the charger, if not, disassemble the shell and replace a 3A fuse.

It is best to wait until the fan stops and then pull it out, the green light should be more than 95%, which does not mean that it is 100% full. It is recommended to continue charging for another 1-2 hours. The fan will stop automatically, which is also a reasonable design of the charger, don't worry about why the fan is still spinning, because it is not fully charged yet.

Basic introduction. The principle of charging is that the voltage of the charger is higher than the voltage of the battery, in order to be able to charge, the greater the electromotive force difference between the two, the faster the charging, the greater the charging current, so the maximum voltage of the general 24V charger is 28V, and 60A is the output current capacity of the full load, and when you charge, the charger already has a load, the voltage at this time is the voltage that the battery is charging, and the current of 40A is the charging current, and this current will become smaller and smaller with the completion of charging. In addition, the size of the charging current is also related to the capacity of the battery.

EV charger light flashing fan does not turn Reason:

1. The charger may be faulty;

Second, the battery itself may be faulty;

3. The charging line may be faulty.

Solution 1:

There is no distilled sulfur water (sulfuric acid) in the battery, so just add it. If not, replace the battery.

Solution 2:

Disassemble the charger to see if the fuse is blown out, and if it does, replace it with a fuse of the same specification.

Hehe... Anyway, the motor is a problem. Come.

Like hands-on words. [Be careful and careful] Tear it down yourself. See if the motor rotates tightly.

Tight words. Add points appropriately. Engine oil or something.

Do you want to change the motor? It doesn't matter ... Check the connection power cord.

Hold the wire. See if it stops turning from time to time. Yes.

Keep checking that place. Loosened. Under Links.

If the contact of the solder joint is poor, take it apart and check it to see if there is any obvious desoldering.

When the electric vehicle charger is connected to the power supply, the green light is on, but the charging red light is not on, what is the reason?

Dear Kiss I am happy to serve you The electric car charger is connected to the power supply, and the green light is on, which means that the charging red light is not on, and the reason is that the charger is damaged. There is also a possibility that the battery has not been charged for a long time, and the battery is in a state of power loss. In this way, it is necessary to use professional charging equipment for charging.

1. When the power cord is disconnected, check the circuit from the plug to the charger, and test whether the 220V in the charger is normal. 2. Rectifier circuit failure. 3. The circuit fuse in the charger is broken, the voltage is abnormal, and the power management chip is damaged.

5. The charger has no output.

1. The battery car cannot be charged, and a large part of the reason is that the charger is damaged. The fuse of the charger is blown out, the components are damaged, etc., which can easily cause the battery car to fail to charge. You can test it with the same type of charger to see if the battery car can be charged normally after changing the charger, if it can be charged, it is the charger is broken, and you can replace it with a new charger.

2. The line is connected virtually, short circuit, etc., which can easily cause the battery car to fail to charge normally. At this time, you can first check the line visible to the naked eye to see if the line is plugged in tightly. If the battery car still cannot be charged normally after the external wiring is fixed, it is most likely that the internal wiring or fault of the battery car causes the battery car to fail to charge normally.

3. The old fast key of the battery, the internal line of the road, the bright connection, and the short circuit will cause the battery car to be unable to charge. If the battery has been used for a long time and has reached the end of its life, it may not be able to be recharged. If the battery has not been used for a few years, and the owner usually pays more attention to the maintenance of the battery, then the battery car cannot be charged is likely to be caused by the internal failure of the battery, which can be solved by repairing and replacing the battery pack.

It is possible that the charger has been damaged and needs to be repaired. As for what the problem is, it needs to be checked by professional Yu Sui personnel to know. Generally, the yellow light is often on to indicate that the voltage of the battery has reached the upper limit, if the electric fan is not ruined, the problem is big, and the switching power supply may be broken.

Most of them are charged badly, it is also possible that the battery connection line is disconnected, try to change to the same charging leather car Kai device If it can be charged, it is the charging sail friend is broken, if it can not be charged, the battery connection line is broken.

If the charger has a response or there is a spark after the short circuit, the charging line of the car should be checked; Otherwise, the charger is disconnected. How high is the battery voltage? Is there a voltmeter?

Judging from your description of the situation, the charger's fan does not turn, indicating that the charger is faulty, you can change the charger and try it.
