What s going on with the car wireless charger not responding and the indicator light not lit?

The reason why the car charging indicator light does not light up is that the charging indicator filament is open; Fuse.

Burn-out makes the indicator circuit impassable; or the power cord of the indicator light regulator is open or the connector is loose; Loose cable head on the pole; Ignition switch failure; Poor contact between generator brushes and collector rings, etc. If the fuse is intact, it is loaded in no-load conditions.

The main causes of this type of fault are: open circuit and short circuit of overvoltage and overcurrent protection circuit; The vibration circuit does not work; Power overload, rectifier diode in high-frequency rectifier filter circuit.

Breakdown: Filter capacitance.

Leakage, etc. <>

There are two types of faults in the charging indicator: the charging system can be charged and not charged.

Method 1: When the ignition switch is turned on, the charging indicator light does not light up, and the generator can generate electricity again after the engine starts, indicating that the generator charging system is normal. Check that the charging indicator on the dashboard is OK and replace it if the filament is disconnected.

Method 2: The ignition switch is on, the charging indicator light is not on, and the generator cannot generate electricity after the engine starts, the troubleshooting method is as follows: Turn off the ignition switch and check the instrument fuse. If the fuse blows, replace the fuse of the same specification; If the fuse is intact, continue to check.

Turn on the ignition with a multimeter.

Detects the voltage value on the fuse. If the voltage is zero, it means that the ignition switch and the line between the ignition switch and the fuse are faulty and should be repaired or replaced. If the voltage on the fuse is normal, check for poor contact between the generator brushes and collector ring or a faulty internal circuit of the regulator.

Maintenance method: First, use a multimeter to measure whether each component of the high-frequency pulse transformer is damaged: after eliminating the breakdown of the high-frequency rectifier diode and the short circuit of the load, measure the DC voltage of each output terminal.

If the output is still zero at this point, it can be determined that the control circuit of the power supply is faulty. Finally, a multimeter is used to statically measure whether the rectifier diode and low-voltage filter capacitor in the high-frequency filter circuit are damaged. If the above parts are damaged, replace them with new ones, and the general fault can be eliminated.

However, it should be noted that the output line is broken, open or virtually welded.

It will also cause this kind of failure, so pay attention to it when repairing.

It may be that the car charger is damaged, there may be parts damaged, it may be that there is a short circuit in the incoming wire of the charger, you can buy a new charger, or go to a professional place to repair it.

The ignition switch is faulty, the indicator light or regulator power line is in poor contact, the charging indicator is disconnected, and the generator brush is in poor contact with the collector ring, etc.

In this case, it is likely that the fuse is blown and the circuit of the indicator is impassable.

Today I will give you an answer about electric vehicles.

What is the reason why the charger does not respond and the indicator light does not light up? What should I do if the power indicator of the EV charger does not light up? Teach you problem-solving and self-leading skills.

The battery charger indicator does not light up. Generally the charger is broken. The charger is not connected to a power source.

Thirdly, the charger indicator is broken. The reason why the indicator light does not light up after the EV charger is plugged in is that the power cord is broken.

Make sure the charger input power plug is properly connected and plugged into a normal power outlet.

If the situation does not change, please open the case of the charging product and confirm the fuse in the machine.

Whether the connection is correct and whether there is an open circuit.

If the circuit is not open, confirm that the power input cable is not damaged. After troubleshooting the power input line, check the parts near the high-voltage area of the board for virtual soldering.

Opening may cause the above failures. If the machine's fuse breaks, do not replace the amps.

Fuses (The fuses of the charger are usually. Focus on checking whether the parts are damaged. If there is damage, replace it with the same type.

Extended information: Precautions for using electric vehicle chargers, the charging voltage and current of the charger should be the same as that of electric vehicles, and 5 battery chargers cannot be used to charge 4 batteries. When charging, users should pay attention to the charging port that inserts the battery before plugging in the power plug.

While the user is charging, the charger should display a red light. When fully charged, the green light comes on. Once the charging port is plugged in, the green light will stay on to find out why there is no charging.

If the electric secondary length does not take time, it is necessary to fill it up. Users should turn off the main switch under the seat and place it indoors or in a cool, dry place.

It is strictly forbidden for users to disassemble the charger secretly. Because of the high internal voltage, there is a risk of electric shock, especially with wet hands. I hope mine can help you, and I also hope you can help me**, like, support me more, and follow me more.

The reason is that the power supply line is disconnected. Check whether the charger input power plug is connected, you can plug the charger input plug into the normal power socket, if the situation is still the same, open the charging shell, observe whether the fuse connection in the machine is intact, whether there is an open circuit, if there is no open circuit, now check whether the power input line is good. After troubleshooting the power input line, check whether the components near the high-voltage area on the circuit board have false soldering.

It may be because of the battery circuit problem, or it may be because the charger is unstable, these are the reasons that will lead to such reasons, go to a professional store to find a professional master for maintenance.

There is a problem with the bulb of the indicator light, and the indicator must be replaced in time, so that it can be lit up and there will be no big problems.

It is very likely that the power cord of the incoming power has failed, and you need to go to the 4S shop for repair in time, and do not deal with it yourself, causing the problem to become more and more serious.

Do you first look at the loose clamp of the battery under your hood? If it is loose, tighten it with the corresponding wrench, if not, go to the repair shop and check the car generator!

Summary. Hello, the charging indicator of the electric vehicle is not lit, the relevant reasons and treatment methods are as follows. First, the charging connector needs to be checked first, and if there is a problem, it needs to be replaced.

Second, the phenomenon caused by the problem of the relevant charging converter needs to be checked by the charging converter. Third, this phenomenon caused by the problem of the charger plug or base needs to be checked for the plug or base.

Fast charging and slow charging can be charged normally.
