My tram battery is not fully charged in winter, what s going on.

Road conditions in winter are more complex than in other seasons, and no one can predict what will happen on the road, so it is particularly important to check the vehicle before departure. Below, Lu Hong will teach you a very simple self-inspection method - watch first and then listen.

Look—in winter, battery electrode wiring is susceptible to oxidation, so once you find green oxide, you need to clean it up. If it is not removed, it will cause the generator to be insufficient and affect the service life of the battery; Also look at the brightness changes of the headlights. When the car is idling, the headlights quickly turn from bright to dark, indicating that the battery needs to be replaced.

Listen – you can also pay attention to the sound of the engine. Under normal circumstances, the engine makes an abnormal noise when starting, usually a slight squeak, but it may disappear after two or three seconds or more; If the battery of your car is not enough, the frequency of abnormal noise will gradually increase, which indicates that the battery has a deep loss of power and needs to be replaced.

1. For batteries that have been used continuously for more than 3 years, it is necessary to check the remaining power every 2 months in winter. If there is a serious power loss, it is necessary to replace the battery with a new one in time.

2. Some car owners will travel for a long time during the New Year, in this case they can not forget the battery, the battery is afraid of low temperature, and the battery capacity in a low temperature environment is much lower than the electric capacity at room temperature. Therefore, if you do not drive for a long time (more than two weeks), it is recommended to remove the battery and put it in a warm place to prevent the battery from being damaged by freezing.

According to the summary of experts from the China Battery Repair Agency, some data show that 80% of the broken down vehicles are caused by battery failure. The cold winter has come, the "workload" of the battery has become larger, we need to give it more care, regular self-inspection, when the battery needs to be replaced, decisively replace and choose a reliable brand, Luhong Technology is a reliable brand.

Winter will cause the charging molecules in some poor quality batteries to be inactive, so some batteries will never be charged.

The battery has requirements for the use environment (temperature). When you buy a battery, the manufacturer will come with an instruction manual. Take a look at the battery instruction manual and you may understand.

One thing is for sure, the outside temperature seems to be very low (over -15 degrees C).It may be that the battery exceeds the requirements of the use of the ambient temperature (high temperature and low temperature), so it will show that the power is insufficient. This is a normal reaction due to temperature.

1. The electric vehicle pool cannot be charged because of the large change in ambient temperature, most of this situation is because the electric vehicle battery itself is not a low-temperature battery, and when it is used in a low-temperature environment, it will cause the battery to freeze inside because the temperature is too low, resulting in a large internal resistance of the battery and a decrease in chemical activity, which makes the discharge capacity drop sharply, or even not discharged.

This can be transferred to a place with a suitable temperature, and after a period of time, the battery will regain some of its capacity, and if it is used frequently, the battery will be seriously attenuated or scrapped due to low-temperature lithium evolution.

2. When the lithium battery of electric vehicles is used, the power is often completely used up, which is often said to be too much deep discharge, and the battery cannot be charged due to this behavior If the charger is normal, then the battery is often in a high active state under electricity, resulting in the battery attenuation too fast and the life is exhausted. This can only be replaced by the battery.

3. Because of the failure of the charging interface, the possible short circuit is caused, so that the lithium battery protection board of the electric vehicle triggers the protection function by itself and cannot be charged, which requires the maintenance of the charging interface.

Your problem needs to be typed, so you need to wait patiently, Xiaomi will sort out the plan for you immediately! 珞

4. Another problem is that there may be a problem with the charger of the lithium battery of the electric vehicle, so you can check the charger first.

Refer to it. Hope it helps.

In winter, the lithium battery of the electric vehicle cannot be charged, you can go to the place where the battery car is repaired to consult to see if the charger is broken, or what the problem is.

In winter, the lithium battery of electric vehicles can not be charged, usually for these reasons:

1. The battery life is over.

Workaround: Replace or repair the battery.

2. The fuse in the battery fuse tube is broken.

Solution: Replace the fuse.

3. The battery safety tube is in poor contact with the safety seat.

Solution: Adjust the position of the two to make good contact, or replace the fuse.

4. The charger has no output voltage or low output voltage.

Workaround: Replace or repair the charger.

5. The charger is in poor contact with the AC 220V power supply.

Workaround: Unplug the power supply.

6. The charger indicator is abnormal, resulting in false fullness.

Workaround: Replace or repair the charger.

7. There is no voltage between the positive and negative poles of the dial.

Solution: Poor contact or broken wire: Replug or replace the wire.

8. The light-emitting tube is damaged.

Solution: Replace or repair the light-emitting tube.

9. There is a circuit open circuit on the dial-up circuit board.

Solution: Replace or repair the instrument circuit board.

Lithium batteries have an impact on the range in the cold winter.

Lithium-ion batteries work on the principle that the electrolyte inside changes through a chemical reaction, and a potential difference occurs at the positive and negative electrodes to produce an electric current. In a low-temperature environment, the electrolyte moves quite slowly, which affects the transfer activity of lithium ions between the positive and negative electrodes, resulting in a decrease in the charging and discharging performance of the battery.

To put it simply, in a low-temperature environment, it is not that the lithium battery is really dead, but that there is power but cannot be released normally. According to analysis data, the capacity of ordinary lithium batteries will be reduced by 20 at zero degrees Celsius, and when it reaches minus 10 degrees Celsius, the capacity may only be about half.

Extended Information: Precautions for Winter Use:

1. Find a warm place to charge.

When the ambient temperature is lower than 0, charge the electric vehicle, the system will automatically heat the battery cell first, and when the temperature of the battery cell reaches more than 5, it will really start charging the vehicle. Some EV owners feel that charging their EV in the winter suddenly slows down, which is actually an extra time to heat up the battery cells before charging the vehicle.

Therefore, when the car owner usually charges the car, he should try to choose the underground parking lot, closed garage and other places. This helps to improve the activity of the battery, which not only reduces the loss of range, but also improves the efficiency of charging and saves time.

2. Charge the battery for a short time before traveling.

The day before, the electric car was still 60 or 70 percent charged, but the next morning it was only 30 percent or less charged. Some people call this situation "running electricity". In fact, this kind of "running power" is not a failure, but a fault caused by low temperature.

In the process of driving the electric vehicle, the battery is in a state of continuous discharge, the temperature will be relatively high, and the voltage of the battery is relatively high.

However, after being parked in a low temperature state for a whole night, the battery has cooled down and the voltage drops, at which point the car's system will automatically adjust the displayed power and range, which creates an illusion of "running power". In this case, you generally only need to go out in advance and charge the battery for about 10 minutes.

3. Drive steadily and don't be in a hurry.

When driving an electric vehicle, you should accelerate slowly and avoid intense driving methods such as deceleration, sharp turns, and sudden braking. Good driving habits can effectively reduce the rate at which the battery drains power. The time to start the car should not exceed 5 seconds each time, and the interval between starting again should not be less than 15 seconds.

If the battery mileage drops too much, you should go to the 4S store in time to check the battery of the car, replenish the electrolyte of the battery in time, and adjust the specific gravity of the electrolyte.

Hope, thank you!

In winter, it is cold, generally in the case of the same battery capacity and voltage, the cruising range is about 20-30% less than in summer, so we don't have to worry, it is normal for electric vehicles to reduce power quickly in winter and shorten the cruising range. Because the ideal charging temperature for electric vehicles is 25 degrees, if the temperature drops by one degree, the corresponding range will also be reduced by about 1%. For example, if you are fully charged once in summer, you can last 50 kilometers, and if the temperature drops to 0 degrees in winter, it will be reduced by about 15 kilometers, that is, it can only last 35 kilometers.

Another reason is that the battery active material of the electric vehicle will decline in winter, so that the resistance will increase, and the capacity of the battery will decrease.

The battery car is not fully charged in winter, specifically due to the above two reasons, if you still can't find it, it is recommended that you go to repair it, or change the battery, I hope mine is helpful to you.

If you have a problem with your battery, although the battery will lose a little power in winter because of the cold weather, it will not be too big, and the battery quality is not good or there is a problem with the charging plug before it can be fully charged.

Put away the machine with a warm JLK55

Reason: The temperature is very low in winter, and it may exceed the requirements of the battery for the ambient temperature at this time.

Especially in winter; Do not charge the battery car directly in the cold car, because the battery car itself is affected by the reduction of battery activity and the increase in air density, if the cold car is charged directly; In terms of energy consumption, it is equivalent to adding insult to the problem of the battery, and the use of a charger with temperature sensing, and can adjust the charging voltage and current according to the temperature is one way.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, dear, the exclusive technician of the car master will serve you, attentively, carefully and attentively answer your car questions, find solutions and solutions to the corresponding problems for you, and will definitely provide you with satisfactory service! Hope mine can help you! Dear, hello, the battery can't be charged in winter, and the treatment method is as follows.

First, the aging and attenuation of the battery caused by this phenomenon under normal circumstances, the service life of the battery is about 3 to 4 years, if the service life is exceeded, it is recommended to replace the new battery. Second, the battery does not store electricity due to the low external ambient temperature, so it is best to charge the battery indoors, because when the external ambient temperature is too low, the internal molecular activity of the battery is low, and the power storage capacity is particularly poor.
