How to maintain the electric vehicle battery, how to maintain the electric vehicle battery?

1. According to the working characteristics of the battery, reasonable maintenance and use are important for the extension of battery life. The correct use and maintenance of lead-acid batteries is very necessary, and the correct use has a great impact on the capacity and life of the battery, and mastering the correct charging method is the key in the use process. First of all, it is necessary to choose a good charger, and the charger indicators include output voltage, charging current, turning light point, etc.

In summer, when the weather is hot, you should choose a charger with a lower turning point; Winter is the opposite. 2. Pay attention to charging frequently, and don't wait for the electricity to run out before charging. In a freshly discharged battery, lead sulphate dissolves easily and converts into an active substance.

Once left for a period of time, lead sulphate can easily form coarse crystals, causing irreversible sulfation. In addition, it is also necessary to pay attention to regular deep circulation, that is, to recharge the battery after it runs out of electricity to prevent the battery from being passivated, generally once a month. 3. During the transportation and installation of the battery, it is strictly forbidden to hit the pulling pole.

Do not short-circuit the positive and negative poles. Do not use batteries with different capacities and different performance together. 4. Pay attention to heat preservation when charging in winter.

Otherwise, the electrical energy cannot be converted into chemical energy normally, and it cannot be charged. When the temperature of the electrolyte decreases, the dissolution of lead sulfate decreases, the activity of molecules inside the battery decreases, and the internal resistance increases. At this time, charging, not waiting for sufficient, the charger will mediate, the user thinks it is full, and continues to use.

When the lead sulphate crystals become larger, irreversible sulfation is formed. ]

The "Jinhai Electric Vehicle Money Saving Guide" mainly introduces how to extend the battery life of electric vehicles, and how to maintain the battery of electric vehicles, so that electric vehicle users can save more money. Electric vehicle lead-acid battery replacement expenditure, is the largest cost in the process of electric vehicle use, now electric vehicles in our people's means of transportation, occupy a larger and larger proportion, and with the state of lead pollution serious unqualified lead-acid battery manufacturers shut down and rectify, since January 2011, electric vehicle lead-acid battery **several times**, brand-name electric vehicle battery 48V20Ah has been close to the 1000 yuan mark. Doubling your life span is equivalent to earning 500 yuan.

Let's get down to business!! Lead-acid battery capacity restorer, as the name suggests, is to restore the capacity of lead-acid batteries, and the capacity of lead-acid batteries for electric vehicles will also decline with the use of riding, and it is also necessary to restore the capacity. Today I will talk about the topics that friends who ride electric vehicles are concerned about, how to make good use of the lead-acid battery capacity restorer, how to maximize the life of electric vehicle batteries, how to save the most money in our pockets, after all, it is not cheap to change a new set of batteries.

Like my 48v20ah, the trade-in of electric cars in our street will be sold for about 750 yuan, and if it is a new one, it will be close to 1000 yuan. My battery is 16 months old, and I used to be able to run more than 60 kilometers, but now it is about 15 kilometers. But I only changed one of the four pieces, and I was able to run more than 50 kilometers again, haha, saving more than 700 oceans.

Let's talk about my approach, because I use Jinzhou's Jinhai lead-acid battery capacity restorer, so I named this article "Jinhai Electric Vehicle Money Saving Manual". ====The following is omitted. . . It's too long, it's too detailed, you can search for the "Jinhai Electric Vehicle Money Saving Book" and read it, it will be very beneficial. ]

Nowadays, more and more people use electric bicycles as a means of transportation. So, how to maintain the power ——— battery of electric bicycles, relevant experts put forward five suggestions: 1

Do not store the state of 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 the capacity of the battery. 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, which can extend the life of the battery.

2.It is necessary to regularly inspect that in the process of use, if the driving range of the electric bicycle suddenly drops by more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery group has a short circuit phenomenon such as broken grid, plate softening, and plate active material falling off. At this time, you should go to a professional battery repair institution for inspection, repair or matching.

3.Do not discharge high current When the electric bicycle is starting, carrying people, and going uphill, it is best to use the pedal to assist 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.

4.In general, the battery is charged at night, and the average charging time is about 8 hours. If it is shallow discharge (the mileage is very short after charging), the battery will be fully charged quickly, and if it continues to charge, it will be overcharged, resulting in water loss and heat generation of the battery, reducing the life of the battery.

Therefore, it is best to charge the battery once when the discharge depth is 60%-70%, and it can be converted into riding mileage when it is actually used, and the necessary charging is carried out according to the actual situation to avoid harmful charging. 5.To prevent high temperature exposure, electric vehicles are strictly forbidden to be exposed to the sun.

The environment with too high temperature will increase the internal pressure of the battery and make the battery pressure limiting valve forced to open automatically, the direct consequence is to increase the water loss of the battery, and the excessive water loss of the battery will inevitably cause the battery activity to decline, accelerate the softening of the plate, and the shell heats up, the shell bulges, deforms and other fatal injuries during charging. ]

Because as long as it is a lead-acid battery, in the process of use, more or less will produce sulfide crystals, after discharging not timely charging vulcanization crystals generation speed is very fast, battery scientists have tested, fully discharged batteries are not charged in time, 24 hours after the naked eye can see the newly generated sulfide crystals. ]

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 all at once 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.

1. Don't replace the charger casually, and don't remove the speed limit of the controller.

Chargers from various manufacturers generally have individual needs, so don't change them when you're not sure. If the mileage requirement is relatively long, and multiple chargers must be equipped for charging in different places, the charger that is replenished during the day is used as a separate charger, and the original charger is used at night.

2. Protect the charger.

The general instruction manual has instructions on protecting the charger. Many users do not have the habit of reading the manual, and often think of looking for the manual after the problem occurs, and it is often too late, so it is very necessary to read the manual first.

3. Charge every day.

Even if you don't have a long battery life and can last 2 to 3 days on a single charge, it is recommended that you charge it every day so that the battery is in a shallow cycle state and the battery life will be extended. Some early mobile phone users think that the battery is best to be charged after it is basically used, this view is not right, and the memory benefit of lead-acid batteries is not so strong.

4. Charge in time.

The vulcanization process begins after the battery is discharged, and within 12 hours, there is a noticeable vulcanization. If not charged in time, these vulcanization crystals will accumulate and gradually form coarse crystals, and the general charger is powerless against these coarse crystals, which will gradually form a decline in battery capacity and shorten the service life of the battery.

5. Regular deep discharge.

It is also beneficial for the battery to undergo a deep discharge on a regular basis"Activation"battery, which can slightly increase the capacity of the battery. The general approach is to make a full discharge of the battery at regular intervals. The method of full discharge is to ride the bike to the first undervoltage protection under normal load conditions on a flat road.

After a full discharge, the battery is fully charged. You will feel that the battery capacity has increased.

1. Do not store it without electricity.

The state of power loss refers to the fact that the electric vehicle 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.

2. 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.

3. Master the charging time.

In general, electric vehicles are charged at night, and the average charging time is about 8 hours. In the case of shallow discharge (the driving range is very short after charging), the battery will be fully charged quickly, and if it continues to be charged, it will be overcharged. Therefore, it is better to charge the battery once when the depth of discharge is 60%-70%.

Fourth, prevent high temperature exposure.

The environment with too high temperature will increase the internal pressure of the battery and make the battery pressure limiting valve forced to open automatically, the direct consequence is to increase the water loss of the battery, and the excessive water loss of the battery will inevitably cause the battery activity to decline, accelerate the softening of the plate, and the shell heats up, the shell bulges, deforms and other fatal injuries during charging.

Fifth, it is necessary to conduct regular inspections.

In the process of use, if the driving mileage of the electric vehicle suddenly decreases in a short period of time, it should be inspected, repaired and matched by a professional battery repair institution in time.

Generally, there is no need to maintain, you can use it normally, add the battery to heat up when charging, it should be a lack of water, find a professional master to give you an appropriate amount of battery-specific replenishment liquid. I hope my answer is helpful to you.

Generally, there is 30% so that you need to charge, that is, you can charge it when you see the display table yellow in riding, and you don't need to rush until the light turns green in summer, and you can also do it for one to two hours in winter, don't rush for a long time, the battery will become bulging. Because turning green does not mean that the electricity is not charged, he is floating charge, and there will still be a small current. The charger usually takes 8 hours to charge the battery.

Do not use the car for deep discharge.

Data expansion: battery, also known as battery, it is a kind of electric storage equipment that can alternately convert between electrical energy and chemical energy. The battery is mainly used to provide power supply for the starter and point system of the car, and to provide a stable DC power supply for the automotive electrical appliances, so as to ensure that the electric circuit and DC illumination system of the car can be supplied normally when parking.

One of my 4 batteries has no power with electrolyte, why?

Because the battery electrolyte level is lower than the specified value, if a large amount of electrolyte is missing, the battery capacity will be insufficient. In that case, the battery is damaged and needs to be replaced.

Just pay general attention to the following:

1. Don't charge frequently.

Because people often use electric vehicles now, they have developed the habit of charging once a day, but the battery life is related to the number of charging cycles, and frequent charging will also reduce the battery life. Therefore, it should be charged when there is still about 30% of the battery left, which can effectively extend the life of the battery.

Second, if it is an electric car that you just bought, you must press it to be fully charged before riding.

The battery in the new electric car has been lost when it flows into your hands, and if it is not fully charged and ridden directly, it will accelerate the battery loss, which is not conducive to battery maintenance.

3. If you don't ride for a long time, you should charge it on the first day of January.

Not riding for a long time can easily cause battery power loss, resulting in sulfation of battery plates, reducing battery life, and even possibly scrapping.

4. Do not charge in high temperature exposure.

During the charging process of the battery, heat will be emitted, and high temperature exposure will easily cause the battery to bulge and affect the battery life.
