I have a battery on a toy car and the charger is broken, what should I do.

Just see if the charger is about the same size.

The output voltage should preferably be the same. Above the battery, the battery will break, below the battery, it will not be charged.

As an accessory, the charger itself is a consumable product, and its service life is generally about 2 yearsWhen it is damaged by a fault, it is generally time to replace the new charger, and at this time, it is meaningless if you choose to repair it, so when the charger is broken, it is generally replaced.

EV chargers.

It is a charging device specially configured for the battery of electric bicycles! 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.

If the charger of the electric car is damaged, it cannot be repaired, and if the charger is damaged, it can only be replaced with a new one. Electric vehicles are a relatively common means of transportation, which is also a relatively simple means of transportation. The main components of an electric vehicle include a frame, an electric motor, a battery, and a controller.

First of all, use a multimeter to measure whether the components of the high-frequency pulse transformer are damaged: after excluding the breakdown of the high-frequency rectifier diode and the short-circuit of the load, then measure the DC voltage of each output terminal, if the output is still zero at this time, it can be sure that the control circuit of the power supply is faulty, and finally use the multimeter to statically measure whether the rectifier diode and the low-voltage filter capacitor in the high-frequency filter circuit are damaged, if the above-mentioned components are damaged, replace the new components, and the general fault can be eliminated. But beware:

Broken output line or open welding and virtual welding can also cause this kind of failure, and this situation should be paid attention to when repairing. For charger maintenance, we generally listen to the user's symptom description, analyze the approximate cause, and then open the broken product, determine the broken parts, and then repair and replace.

There are generally four reasons why EV chargers don't charge. 1. The charger or battery fuse is blown and the charger is not charged If the charger fuse is blown out, then it will cause the charger to not operate normally, resulting in the failure to charge. And if the battery fuse is blown out, then the charger is normal in time, and it will not be charged.

Therefore, in the case of a blown fuse, the easiest solution is to replace it with a new one. Second, the battery pack wiring is loose or the charging socket is damaged, resulting in the charger not charging If the battery pack wiring is loose, then the battery can not be charged normally, for this case, reconnecting the wiring can be solved. Similarly, if the charging socket is damaged, then the current will not be transmitted normally, causing the situation of not charging.

And for this case, the charging socket needs to be replaced. 3. The internal components of the charger fall off, resulting in the charger not chargingMany users like to carry the charger with the car, but they do not know that this way may cause the internal components of the charger to fall off, resulting in inaccurate charger parameters, or even unable to start, causing the charger not to charge. Of course, for this situation, the general solution is to replace the charger with a new one, rather than choosing to repair it, because the components fall off and then go for repair, it is easy to damage it again.

Fourth, the battery is charged, resulting in the charger not charging If the battery has been charged, there will be a situation where the light will jump as soon as it is charged, which does not mean that the battery is full, but that the charger cannot be charged normally. For a charged battery, you can generally choose to replace it with a new battery. Maybe some users want to say, you can choose to add water, in fact, for the battery that is inflated, adding water no longer works.

In addition, it is important to note that most of the current batteries are maintenance-free batteries and do not need to be added with water.

Hello, is there anything else you need to consult? If not, think I'm saying it well, please give me a thumbs up, I wish you a happy life, thank you.

Questions. The indicator light flashed 80 and could not be charged.

There are only a few cases. You can check them one by one.

The charger of the battery car cannot be repaired. You can change a charger directly at the place where the battery car is repaired or where the battery car is sold. The charger won't cost much. It's safer to replace one than to repair one.

The charger used in the battery pack of electric vehicles will be replaced with a new one if it is broken, and it is not cost-effective to repair, and the voltage should be consistent when purchasing.

In addition, it is necessary to distinguish the charging port type, and the T-type socket has positive and negative pole identification Check it carefully, and it is easy to damage the charger and battery pack if you buy it by mistake.

It is not the original charger is generally 35 40 yuan a piece, the original charger is generally 70 75 a piece, and the labor cost of repair starts at 50 yuan, do you think it is necessary to repair it?

1.Check and find out what's wrong.

2.Repair or replacement parts.

3.The second step is to buy one if it doesn't work.

4.Use.

Hello, I am your exclusive service technician, attentive, attentive and careful to help you solve the problem of using the car car charger damaged into the big belt line maintenance, in this case, the charger inside the words are generally a big fuse noisy, if the charger display including the indicator light can not be lit normally, first of all, you can disassemble the charger, see if the charging fuse inside the charger appears to imitate the front of the broken circuit. If the fuse is not broken, check the connection line of the internal controller to see if it is loose.

First, as an accessory, the charger itself is a consumable product, and its service life is generally about 2 years.

Second, due to the complex internal structure of the charger and the distribution of components, if you want to detect the fault of the charger, it takes a lot of time, which means that the maintenance cost increases, and the charger itself is not high, which will make the maintenance meaningless. Because the maintenance master often falls into a dilemma and loses himself, therefore, the electric vehicle charger is broken, and many maintenance masters recommend replacing it directly.

Third, there is uncertainty about whether it can be repaired well. Don't look at the charger is small, but there are a lot of components inside, if one of them fails, to find out the maintenance master needs to have a certain circuit knowledge, and at present, many electric vehicle maintenance masters are mostly from the bicycle industry, do not have this knowledge. Therefore, it will be more difficult to repair, and you can only choose to replace it with a new one.

Fourth, the maintenance effect is not obvious. Why? Because the repaired charger may be damaged twice in a short period of time, causing the components to fall off, which will lead to a decrease in charging efficiency and even a bad battery. Therefore, it is more practical to choose a replacement than a repair.

Judging from these four reasons, if the EV charger is broken, you should still choose to replace it. For electric vehicles, it is necessary to strengthen the maintenance of electric vehicle chargers on a daily basis.

Precautions. First of all, carefully inspect the various components on the circuit board to see if the appearance of these components is burned or there is electrolyte overflow, and whether there is any ambiguity between smells and smells.

Then measure the resistance value of the power input terminal, if it is less than 20ok, it means that there is a local short circuit phenomenon at the back end, and then measure the resistance value of the positive and reverse resistance values of the four rectifier diodes and the resistance value of the two current limiting resistors respectively to see if there is a short circuit or burnout.

Finally, measure whether the power filter capacitor can be charged and discharged normally, whether the switching power tube is broken down, and whether the UC3842 and its surrounding components are broken down or burned out.

It should be noted that because the measurement is on the road, the measurement results may be wrong or misjudged, so the components can be welded down for measurement if necessary. If this is still not the case, measure whether the input power cable and output power line are internally short-circuited.

Hello, dear. If the EV charger is broken, it is recommended to go to a specialized repair shop for repair. A good EV charger is to use positive and negative pulse technology, which can effectively prevent, inhibit and eliminate the vulcanization and polarization of the battery.

It can keep the new battery capacity stable for a long time, restore the capacity of the old battery that has been polarized and the capacity has decreased, and effectively extend the battery life by 2 3 times. It has intelligent timing protection function, automatic temperature compensation function, power grid instantaneous impact protection, super moisture and corrosion resistance, and so on.
