What is the reason why the EV charger shows that it is fully charged, but there are only two bars of

The electric car has just been fully charged, and as soon as it accelerates, it will drop two bars of electricity, what is the reason, tell you the answer.

In fact, the service life of an electric vehicle is determined by the electric motor, followed by the battery; Generally, the motor has quality assurance, and it can be used normally; However, if the battery is used and charged improperly, the service life will be greatly reduced; Therefore, the use of batteries is specially introduced; The following are the key points of use of the battery: When the battery is stored, it should be stored after it is fully charged, and it should be taken out for discharge or used once or twice in about a month, and then charged and continued to be stored; This is conducive to prolonging the service life of the battery; Generally, the first three charges of a new battery are best in 8-12 hours, and then it can be mastered in 6-8 hours; It doesn't matter how fast or slow the battery is charged; The key is the discharge time; It can be used for a long time after discharge; As long as the battery can be charged and discharged, it can continue to be used; If you buy a big domestic brand, you can; If you can identify the quality of the product, you can also buy the brand products of small and medium-sized manufacturers; This is more cost-effective; Battery bulging is generally due to air leakage and deterioration, and it is usually the beginning of being unable to continue to use (because some less serious, or better quality batteries can still be barely used); If the battery is bulging, it has no effect on the life of the device; However, some batteries are prone to bursting after the bulging; In the small space of the equipment, it is easy to damage the equipment; Therefore, do not use the battery after the drumming; Generally, the life of the battery is determined by the number of times it is charged and discharged; Generally, the number of recharged batteries for repair and refurbishment is about 50 times, so when you buy, you will swear to tell you that the warranty is three months or half a year; Once the warranty period is over, it will definitely not be long; The number of charging and discharging of batteries produced by ordinary manufacturers is about 100-180 times; The term of use is about one to two years; The battery charged and discharged by a good manufacturer is about 200-300 times; The term of use is about two to three years; The imported and original batteries can be charged and discharged more than 500 times, and the service life is longer; The most taboo of general batteries is overcharging and overdischarging; As long as these two principles are followed, the maximum use and maximum service life of the battery can be used.

This is because of the internal resistance of the battery.

large, itself consumes voltage.

When accelerating, the current is large, and the voltage consumed by itself is also large, so the watch falls from full to one or two bars.

You can change a dial, and some dials don't need to be changed, there is a small screw that can be adjusted in the back, you can adjust it, but don't adjust it too high, if it is too high, the battery display will always be fully charged.

Friend, you said the problem, I feel that it should be, there is a problem with the power display, I am a car repairer, I have also encountered this situation, that is, after replacing the new battery, it will display two batteries on it, but the riding mileage is OK. In the end, it's good to change a dial, some dials don't need to be changed, there is a small screw that can be adjusted in the back, you can adjust it yourself, but don't adjust it too high, if it is too high, the battery display will always be fully charged. I don't understand anymore that I add 541079943 I usually have time at night.

How far did you go before on a full charge? If the riding distance is not much worse than before, it should be that the indicator light is broken or the sensor is broken, and the battery is not very likely to be broken, after all, it is the battery that you just replaced, and it is possible to see if the charger is broken.

The manufacturer manufactures batteries of poor quality, and hopes that the industrial and commercial departments will crack down on counterfeit products.

Causes of self-discharge of the battery. This phenomenon is still very common in real life, for example, many people are used to charging directly after the battery is used up, and after the power is fully charged, it will be placed in the garage for direct use next time, but in fact, it is possible that it will not be used again for a long time, in this case, because the battery of the electric vehicle has the phenomenon of self-discharge, the longer the storage is not used, the greater the power loss, and the faster the battery voltage will drop.

When you ride again after placing it for a long time, it is easy to cause a situation where it is obviously full of electricity, but when you want to accelerate at the beginning of running, you will directly drop two grids of electricity. To avoid this situation, you must often ride an electric car out, and electric vehicles cannot be put on the shelf for a long time. In addition, when installing the battery, be careful to avoid connecting the external metal to the positive and negative electrodes of the battery.

Introduction:

It may be the effect of cadmium-free battery. In the past, there was a heavy metal cadmium in the battery, which has the characteristics of corrosion resistance and long life, and the stability is relatively strong, but because cadmium is a heavy metal, it is extremely harmful to the environment, and the impact on the human body is not to be underestimated.

When your electric car is fully charged, it shows two proofs that there is a problem with your battery. Or if something goes wrong with one section, just change it.

It means that your battery capacity is no longer available. It's time to replace the battery with a new one.

Well, the battery of the electric car is insufficient, the power is insufficient, remember to charge it.

That's because the battery is aging, it can't store the electricity, and it needs to be replaced.

The electric car is fully charged, and the acceleration shows an electric power.

When the battery is charging, there is a constant current charging process, at this time, it is necessary to charge to the floating charge jump voltage, the jump voltage is slightly higher than the floating charge voltage, but after the power is off, the battery voltage has reached the floating charge voltage, and it cannot be charged, which is not good for the battery and loses power.

The charger of the electric car always shows that it is full, but the electric car is dead.

1. The battery battery is completely broken. In a certain way, the electric vehicle battery has a time to be used, that is, it has a certain life. At present, most battery cars use lead-acid batteries, the charging and discharging cycle is about 300 times, normal use for a year and a half, the capacity has dropped to less than eighty percent of the rated capacity, the capacity has become smaller, of course, it can not be charged into the electricity, that is, the surface is charged in, full, there is not much power in the actual inside, and the draft is running at all.

If the battery is left for a long time, it needs to be charged every once in a while to maintain a certain amount of power for it to activate, otherwise it will also be damaged by aging. If the battery is broken, it is generally impossible to repair it and can only be replaced with a new one. 2. If the charger damages the charger of the electric vehicle, there are indicator lights.

A red light will be displayed during the charging process, and a green light will naturally be displayed during the discharge process. However, due to the damage of the charger due to the use of the charger for too long or other problems, it cannot be charged when charging, so there will also be a situation where it is full as soon as it is charged, and it is out of power when riding. If the internal circuit of the charger is in poor contact, it will not work normally after connecting the circuit.

Due to the needs of travel, everyone will charge the battery car in time after using it to prepare for the next use, but it is this blind preparation that makes the battery car lose power. Because even if the electric abrasive car is not running, the battery will always be slowly discharged, and when we fully charge the electric car in advance and wait a few days to use it, the battery is actually damaged.

2.In addition, the aging of the battery will also cause this situation, any part of the battery car has a certain service life, not to mention the battery this most common loss of components, in normal use the battery will slowly age, do not pay attention to the use of the method will accelerate its aging, if you find that the power of the electric car consumes very fast. Hope.

You first check whether your wiring has poor contact, if not, then it may be that the battery is not stored in power. It's time for a new one.

The battery life has reached and the capacity has dropped dramatically, and the battery can only be replaced with a new one.

The battery car is out of power, but it shows full as soon as it is charged. It shows that the ability of the battery to store electric energy has been seriously reduced, and the battery has been dismantled and cannot store enough electric energy, and the vehicle cannot be driven in the "full" state.

The electric vehicle battery is not in the electric fight, but the Tuanyin Spine is charged for about half an hour and shows that it is fully charged, which means that the battery has entered the aging period, and the electric vehicle starts to fall off the road and collapses not far away, and the battery has reached the renewal period.

In this case, it is necessary to see whether the battery is falsely connected, whether the battery is too old for a long time, whether the battery has a vulcanization of the plates, and whether the charger is normal.
