How to solve the problem of acid crawling in the rear terminal of electric vehicle battery filling r

The solution is very simple, first wash the terminal with boiling water to wash the acid, and then apply petroleum jelly or butter.

Causes and solutions to the problem of acid creeping in the batteryThe pole material of the lead-acid battery is generally lead and lead alloy, the battery shell is generally ABS or PP, and the connection and sealing of the battery pole and the shell.

It has always been taken seriously, but there has always been a problem of sulfuric acid leakage due to the poor sealing of the sealant to the connection between the two materials. Accumulator poles.

Column glue requires good mechanical properties, high strength, high toughness, acid resistance, and fatigue resistance; At the same time, for both metal and organic materials.

The bonding is good, and the adhesive surface reaches the same high strength, high toughness, acid resistance, fatigue resistance, high and low temperature charge and discharge resistance and other requirements as the gel itself, so as to ensure that during the service life of the battery, there will be no "acid climbing" phenomenon caused by poor sealing links.

The comprehensive performance of the "Sibo" 301 battery pole sealant developed and produced by Heilongjiang Sibo Technology fully meets the battery pole sealing.

The technical indicators require that the technical level of products in this field is in a leading position, and it completely solves the battery production that battery manufacturers are afraid of.

The phenomenon of "climbing acid".

Electric vehicle battery maintenance method:

1. After half a year of use, with the continuous consumption of water, it will cause vulcanization and softening of the plates, which will cause the battery capacity to decrease or even fail. Choosing to supplement the nano carbasol battery activator and an appropriate amount of distilled water can extend the battery life to more than two years.

2. The lead-acid battery in the battery car is not a lithium battery, and can not be charged at any time, the life of the lead-acid battery is calculated according to the number of flushing and discharging.

3. When charging, the indicator light of the charger is first red and then green, and the floating charge should be guaranteed for 2 hours after the light turns green, which is good for inhibiting battery vulcanization; For batteries that have been left unused for a long time, they should be fully charged once a month, and it is generally better to continue to float for 5 hours after the charger turns red to green.

4. Pay attention to skills in the use of battery cars, and also prolong the service life of the battery. Long-term deep discharge will cause the battery plate to soften and shorten the service life.

5. Prevent high-current discharge.

When starting, uphill, and headwind, try to help with your feet; Prevent long-term discharge, and do not drive after discharging frequently. Charge when the charge level is 1 2 low.

1. Correctly grasp the charging time

Under normal circumstances, the battery charging time is about ten hours, and overcharging should be avoided. When preparing to travel, it is necessary to arrange charging on the way in advance to avoid insufficient power during driving, which will cause the battery to be over-discharged and seriously shorten the battery life.

2. Protect the mobile charger and try to avoid the charger bumps and vibrations.

In order to reduce costs, the current mobile chargers basically do not have a high vibration resistance design, many chargers after vibration, the potentiometer inside will drift, resulting in the entire parameter drift, resulting in abnormal charging. So, if you must use a mobile charger, try to wrap it in plastic foam.

In addition, I have it at the time of chargingEnsure the ventilation of the chargerOtherwise, it will not only affect the life of the charger, but also may cause thermal drift and affect the state of charge, which will cause damage to the battery.

3. It is strictly forbidden to store the battery in the state of power loss

Because the battery is stored in a state of power loss, it is easy to sulfate, and the lead sulfate crystals adhere to the plates, which will block the ion channel, resulting in insufficient charging and a decrease in battery capacity. The longer the battery is idle, the more damaged the battery will be. Therefore, when the battery is not in use, it should be replenished once a month, so as to better maintain the health of the battery.

4. Preheat the battery before going out

It's hereWinter, maybe the electric car still had 70% electricity the day before, but when I drove it again overnight, I found that it was "leaking"!

In fact, this is not "leakage", but "low temperature". In the process of driving the electric vehicle, the battery is in a state of continuous discharge, and the battery will heat up when discharged, so the battery itself is relatively hot, and the battery voltage is relatively high, so it is seen that there is still more power left in the electric vehicle.

However, after being parked overnight on a low winter night, the battery has already cooled down and the voltage drops, and then the BMS will automatically adjust the displayed power and mileage, which is the so-called "leakage".

5. Avoid high-current discharge

When the electric vehicle starts, carries people, and goes uphill, try to avoid slamming on the accelerator, forming an instantaneous high-current discharge. High-current discharges can easily lead to lead sulfate crystallization, which damages the physical properties of the battery plates.

Plan your driving range and keep your battery charged

When driving an electric car in winter, the range generally decreases by 10%-20%, which is about 15-30 kilometers。However, since the current charging piles and other supporting facilities have not yet been fully popularized, it is necessary to plan the itinerary before traveling and leave room for improvement. Otherwise, if the electric car flashes a red light and can't find a place to charge, it will be a big trouble!

It is best not to charge the battery every day, so that your battery will not be durable, and the best maintenance method is.

1.Wait until the power runs out before charging.

2.Check whether the sulfuric acid water in the battery is lacking.

If you don't have it, buy a bottle of distilled water and add it.

When adding, it is best to add to the middle of those two lines (there are two reticles on the top, and the upper one is the lower one under the highest limit, so I don't think I need to talk about it).

3.It's best to apply some petroleum jelly to the contact point, so that it will prevent corrosion, and you will be in big trouble after corrosion.

Add a few more;

1。Do EV batteries need maintenance? How to maintain?

A: Now that e-bike dealers can provide battery overhaul and repair services, consumers should take full advantage of these services. Some brands of e-bikes offer overhaul of the battery.

For example, regular maintenance of the battery can reduce the damage to the battery, which is a breeze for dealers equipped with repair capabilities. For water loss, replenishing water at 70 battery capacity is better than replenishing water at 40 battery capacity.

Some brands of products propose: not overhauling at the specified time is equivalent to giving up the warranty period of the battery. Therefore, consumers should make full use of the battery maintenance conditions to extend the service life of the battery.

The above information is provided by well-known electric vehicle repair stations.

1: Should the battery be charged before the trial of the newly purchased electric vehicle?

A: Yes. Because the battery from the factory to the loading of the car to the consumer's hands have a turnover process, during the turnover period of the battery due to self-discharge will lead to insufficient capacity, so the battery must be charged with the on-board charger until it is fully charged. The same goes for newly purchased batteries.

2: What should I pay attention to when using electric vehicles in summer?

Answer: Avoid exposure to the sun in high temperatures; It is strictly forbidden to charge in a high-temperature environment; Avoid charging immediately after driving at high temperatures, and prevent the charging time from being too long, about 8 hours normally; If the power box is hot or does not turn green when the battery is charging, you should go to the battery store in time to test and maintain the battery or charger.

3: When is the best time to charge an EV battery?

Answer: When the pointer of the fuel gauge on the electric vehicle will be close to the lowest position, it is best to charge the electric vehicle, which is conducive to the service life of the battery. If you ride within 3-10 km per day.

It is recommended that you do not need to recharge, that is, do not short range.

Charge frequently. Failure to do so will result in a premature termination of battery life.

Ways to extend the life of electric vehicle batteries:

1.When the vehicle is started, do not charge it too much, but accelerate slowly and assist it with your pedals.

2.It's best to use your pedals when going uphill or upwind, which is good for your battery and motor.

3.It is best to charge it at one time when charging, and then float it for 1-2 hours after the red light is on.

4.Do not drive with overload and weight, and when you find that the meter shows that the battery is insufficient, you should ride with manpower.

5.Try to avoid sudden braking, frequent sudden braking consumes battery capacity; The faster the speed is designed, the greater the loss of the battery.

6.Prevent overcharging. Since overcharging will cause grid corrosion to accelerate, it is necessary to use a matching special charger for charging. Do not mix chargers due to different battery formulations and processes; Do not charge the battery upside down.

7.Since exposure to the sun will affect the service life of the battery, it is necessary to avoid the battery being exposed to the sun.

8.Ensure that the battery is installed in a good position for heat dissipation, and keep it away from the heat source when charging.

9.Charge frequently.

The use of lead-acid batteries should develop the habit of charging at any time, do not discharge the electricity in the battery and recharge, if the battery is not used for a long time, it is also necessary to ensure that it is charged every month.

1-2 times.

1. Do not store it without electricity.

The state of electric vehicle power loss refers to the fact that the battery is not charged in time after use, which is prone to sulfation, and the lead sulfate crystals are attached to the plate, blocking the ion channel, resulting in insufficient charging and a decrease in battery capacity. The longer the idle time, the more serious the damage to the battery. When the battery is not in use, it should be charged once a month to keep the battery in a "healthy" state.

Second, it is necessary to conduct regular inspections.

3. Do not discharge with high current.

When the electric vehicle is starting, carrying people, and going uphill, please use the pedal to help and try to avoid instantaneous high-current discharge. High-current discharge can easily lead to lead sulfate crystallization, which damages the physical properties of the battery plates.

Fourth, master the charging time.

5. Prevent high temperature exposure.

The maintenance of the battery of electric vehicles is divided into the following aspects from a professional point of view:

1 The best battery charging is to wait for the battery to be discharged 80%, over-discharge will seriously shorten the battery life! In the end, the battery does not store power!

Overcharging can also damage the battery! Because each battery manufacturer has the design life of its own products. (The battery is also the number of times it is charged and discharged).

2.With the original battery charger! Don't just use other models of battery chargers! Because the battery chargers supporting the regular battery manufacturers generally have overcharge protection devices! Otherwise, overcharging will cause the battery to deform and be damaged! Affect its longevity!

3.Check the electrolyte level often! Lack of replenishment of distilled water!

4.Keep the surface of the battery clean to avoid corrosion and self-discharge!

My electric car has a 48 volt battery and I have been using the old battery. After two years of use, I found that there was a fever, and I didn't care about it at the time, and I still handled it as I usually charge the car. Later, I found that the fever was very serious, so I opened the battery box and was dumbfounded, and it was all bulging.

Why didn't the lights change?,I thought I could continue to charge without changing the lights.,So it's bulging.。。。 It looks like it's definitely out of moisture. The 48-volt battery has a total of four 12-volt batteries in series at 12A, I pry open each battery cover, just look at the rubber cap, open the rubber cap, add 15 ml of distilled water to each one, and then the four batteries are charged in parallel (I bought a 12-volt 24-volt charger).

In this way, after charging, it will be disassembled and installed in series on the electric vehicle. . . Oh, isn't it so troublesome. I use a strong current 10-bit wiring board (two empty useless, sold in power appliance stores), with red and green wires to connect the positive and negative poles of the four batteries respectively and fix them on the wiring board, there are two rows of screws on the wiring board, fix the battery line usually do not move, we just need to connect in series on the other row of screws, parallel operation.

It's so convenient, I only need two minutes to do it each time... When one of the batteries can't be charged, go to the repair shop and replace it with the master or boss for a better old battery (they do scrap treatment anyway), and they will be happy to give another 10 yuan each... That's how my electric car has been used for eight years, and I haven't changed the battery to a new one...

It is worth mentioning that I did not carry out parallel charging at the beginning, using the original 48-volt charger, according to the original series charging, and found a phenomenon, their internal resistance is not the same, and the voltage drop appears high and low. The high voltage drop of the internal resistance of the old battery is good, but I found that the voltage drop of the good battery that I exchanged for in the repair shop is also high. If at this time our four batteries are good, there is no electricity for this or several batteries The voltage drop is low, and the power of this or several batteries is high in this series charging state, so that the electric ones continue to charge, and they continue to charge when the charger does not change the light until it bulges...

I suffered this at the beginning...

Don't throw away the battery when it's out of power, you can restore it with one move.

When the appearance of the battery is not damaged, swollen, and there is no sign of short circuit or open circuit, the following methods can be taken to try to repair the inner battery

1. Use the capacitance mode of positive and negative pulses to depolarize the battery, and then completely discharge, so that three cycles, if the capacity has signs of recovery, you can cycle several more times to achieve better repair effect.

2. Add water for repair, add deionized water or purified water when adding water, do not add tap water, it will cause the problem of large battery self-discharge.

A battery is a type of battery, also known as a storage battery, which works by converting chemical energy into electrical energy. Usually the battery refers to the lead-acid battery, that is, a battery that is mainly made of lead and its oxide as the electrode, and sulfuric acid solution as the electrolyte.

A battery is a battery that can be recharged after discharging. There are lead-acid batteries, nickel-iron batteries and nickel-cadmium batteries. The positive electrode of the lead-acid battery is lead dioxide, the negative electrode is lead, and the electrolyte is a dilute sulfuric acid solution.

When charging with an external power source, the electrode and solution can be restored to their original state, and they can be used again after charging.
