How long does it take to replace the electric vehicle battery, and what should I pay attention to?

First of all, let's look at the normal use of the battery. Due to the current mainstream electric vehicle battery.

It is a lead-acid battery and a lithium battery, and the maximum number of charge-discharge times of lead-acid batteries is generally about 360 times, which means that under the normal driving conditions of electric vehicles, if they are charged once every three days, the electric vehicle battery can be used for about 3 years. The maximum number of charging and discharging of lithium batteries is more than 500 times, and if it is charged once every three days, the electric vehicle battery can be used for about 4 and a half years. Therefore, from this level, whether it is a lithium battery or a lead-acid battery, under normal driving conditions, it is only necessary to replace a new battery once every 3 to 5 years.

Secondly, we look at the case of overuse of the battery. Many users like to use electric vehicles to pull goods, or to travel long distances, which makes electric vehicles charge once a day, which means that the battery life of electric vehicles will be consumed prematurely. In the case of lead-acid batteries, they can only be used for about one year, and lithium batteries can only be used for one and a half years at most.

Of course, in this case, the EV battery may also be strained, or even scrapped early. Therefore, from this point of view, excessive use of electric vehicles will require a new battery replacement once every one to one and a half years.

Finally, let's look at the light use of the battery. Some users are likely to only charge their EVs once a week due to the low frequency of their usual use, which is relatively small in terms of battery depletion. In the case of lead-acid batteries, it can be used for about 5 years considering the aging of the battery, while in the case of lithium batteries, it can be used for about 7 years.

Therefore, from this level, whether it is a lithium battery or a lead-acid battery, in the case of light use, it is only necessary to replace a new battery once every 5 to 7 years. Of course, users need to pay attention to the fact that if the electric vehicle is not used for a long time, the battery may also be vulcanized and shorten the battery life, so it is necessary to keep the frequency of charging at least once a week.

In short, how long the electric vehicle battery needs to be replaced is calculated according to the frequency of user use, if the frequency is higher, the shorter the replacement cycle. Of course, if you develop good maintenance habits in your daily life, you can extend the battery replacement cycle to a certain extent.

The electric vehicle battery needs to be replaced in three years. Note that the battery of the electric car is not ridden but also practiced, charged once every two months, and then charged after the power is discharged. The design is not easy to break the battery.

For about three years, try not to charge and discharge too much, so as not to damage the battery plates, so you should usually charge a small current and charge it frequently to keep it fully charged.

In the case of no more bulging amounts, the service life of big brands may be longer than that of small brands, and the controller, motor current have an impact on the battery, and there are some riding habits. The easiest thing is that you can run 100 when you are new, you can ride for 2-3 years or even longer, and now you can run 20-30, and you may need to change.

Now it is generally about 2-3 years, depending on how you ride, usually do not take people to ride yourself, know that the distressed car, do not power up when starting, it is normal to ride for 3 years. The key is not to let the battery lose power, just like people working hungry will have a short life, so try to keep the battery in a full state when conditions permit. Once a month, the battery is used up before charging, so as to prevent the battery from storing its own power from decreasing.

The life of the lead-acid battery depends on the quality of the battery itself, accounting for 70%, another has an impact on the life of the battery is the charge, including the advantages and disadvantages of the charge itself, the power is best in the remaining 20% or so and then charge, in the summer in the shade do not charge for more than 11 hours (even if the light does not turn green), in winter in the warm place to the green and then rush for about 3 hours, pay attention to no matter winter and summer, do not ride a three or five miles to charge, and a rush is several hours, As a result, the battery was scrapped early. Finally, do not over-discharge when riding (that is, when the ride is out of power, slow down for a while, ride for a while), and then the car that has not been ridden for a long time should be charged with full power, and every 2 months the electric ride is empty, and then full, so as to cycle.

The car from 5 years ago had a range of 30 kilometers, and it feels like it can fight for another 5 years.

It doesn't matter how long you want to use it, and it doesn't matter when you want to change it. I know that compared with the new lead-acid battery, the new lead-acid battery and the good adaptation charger feel warm but not hot when charging, and it can be full in 6 or 8 hours (the charger can not be charged by turning the light). If the battery is not deformed (bulging) for several months in a row, the battery and charger are qualified.

If the battery is hot when charging (charged for two or three hours) and feels hot for more than ten seconds, it is recommended to change the charger to try, if it is not hot - the charger is a problem. If there is no change, it is estimated that the battery will be replaced, and the battery will be replaced if the recharging time becomes shorter or longer (when the power is about the same), and it feels that the distance is one-third worse than the original, all of which tell you that it is time to change the battery.

13. Generally, it should be changed once every 2 to 3 years, and it should be inspected regularly to avoid exposure to the sun and accurately grasp the charging time.

Now the batteries on the market are lead-acid batteries, the life of the previous battery is basically 3 to 4 years, and the current battery basically has to be replaced in less than two years, why? Because the previous batteries were all used for primary lead, the life of lead is long, and the batteries on the market now (Tianneng, Chaowei, etc.) are basically used for recycled lead. Recycled lead is the lead in the battery that the manufacturer comes back from the waste company, and the production of new batteries is added in proportion, generally primary lead 3, recycled lead 7!

Because it's like this on the market, consumers will feel that everyone is the same, and there is no problem! In fact, it's no problem! Because the battery life of this production is basically 1 to 2 years!

Some manufacturers will also increase the price by making some high-end products! Therefore, the service life of ordinary batteries is generally 1 to 2 years according to some factors such as driving habits, charging habits, road conditions, etc.! The life of high-end products is about 1 year longer than that of ordinary batteries.

There is definitely no fixed time for how long the battery of an electric vehicle can be replaced, and the battery will not be replaced if it cannot go to the mileage it needs. Whether the battery is sold for a new car or replaced, you must be careful not to be installed by the black-hearted boss with a turnover and maintenance battery. Because these two kinds of batteries are warranted batteries, since they are warranted batteries, they must be second-class or third-class products in the factory.

Although the store will generally help you with the warranty, but you are troublesome. There is also a much greater chance of breaking the warranty period just arrived. There is also a good battery to maintain well to be durable, the most important thing is to use the battery to 30% of the charge.

There are also two or three months or so to use the battery for one or two deep discharges. Deep battery discharge means that the battery of the electric vehicle is basically unable to move and recharge when the car is used.

How often to change the battery of electric vehicles My suggestions are as follows, how often to change the battery, this is not generalized, usually look at the owner's daily riding frequency, as well as the maintenance method of charging There are big factors, such as some users are just a short distance to and from work, so the service life of such a riding frequency can be longer, that is like dozens of kilometers a day, or even hundreds of kilometers, their batteries basically have to be replaced once a year or so. What to pay attention to when changing the battery: I recommend that you go to the store where you buy a car, so that the quality is slightly ***, that is, the battery fails within a year, and the testing instruments in all aspects are more advanced.

Those batteries are basically finished in two or three years. The battery that is replaced is basically not as good as the battery that comes with the original factory.

Mine has only been used for a year, and it is still a brand, and now the value is simply amazing.

Do you think domestic goods can be changed without changing!?

Now the electric car battery can last for two years is already very good, the quality is too poor, don't ask me why? Because I'm an electric car mechanic! Now I don't have the confidence to change the battery.

Summary. Hello, there is no problem with replacing the battery of the new battery car for 2 to 3 years, if your car habits are very poor, the battery use time is relatively short. The battery is a wearing part on the electric vehicle, and this part needs to be replaced regularly, because the performance of the battery will also decrease as the number of charging and discharging times increases.

When charging or discharging, the ions in the battery can move in the electrolyte, and a part of the ions will react with the electrolyte as they move in the electrolyte. As the number of charge and discharge increases, the number of ions in the battery will become less and less, so the performance of the battery will also decrease. If you maintain the correct habit of using the car, you can effectively extend the service life of the battery.

Dear, master the charging and discharging time of the electric vehicle battery. Now is the cold winter, the correct charging time of electric vehicles is about 12 hours, but if in summer, the charging time should be shortened to 6 to 8 hours, do not charge the electric car overnight, the main reason is that the temperature is high in summer, the battery charging and discharging efficiency is fast, and there is a big difference from the winter, the owner must pay special attention.

Pro, the maintenance method of electric vehicle battery is as follows: 1. Do not replace the charger at will, the chargers of various manufacturers generally have personalized needs, do not replace the charger at will when you are unsure; 2. Protect the charger, many chargers are placed in the trunk and gondola, after vibration, the internal potentiometer will drift, so that the whole parameter drifts, resulting in abnormal charging state; 3. Charge every day, even if the continuation ability is not required for a long time, it can be used for 2-3 days on a single charge, but it is recommended to charge it every day to keep the battery in a shallow cycle state and prolong the battery life.

It is better to replace the battery of an electric vehicle every two to three years.

The general service life of electric vehicle batteries is between one and a half years and two and a half years, so you can choose to replace the battery in about one and a half to two and a half years. The new lithium battery for electric vehicles can be used for about two years for ordinary family use.

Electric car features:From the early stage of manufacturing to the current update, electric vehicles are inseparable from several major characteristics, reducing people's travel labor, providing convenience, saving money, meeting travel needs, and can combine themselves to make money and provide efficiency for work; No matter what age group of people, they are holding these wishes to choose different types of electric vehicles that suit their needs. This scene can be seen in the large electric vehicle trading market, some people choose electric bicycles, electric motorcycles, and others choose electric cargo tricycles, electric people tricycles, and shed low-speed vehicles.

The characteristics of choosing a car are the same, but the use is different; Choosing electric bicycles and electric motorcycles is mainly for the convenience of travel for yourself and your family, and to provide travel needs for work, picking up and dropping off children to and from school, and going out shopping. The choice of low-speed scooter is for comfort, to be able to carry the whole family or pick up children without freezing, not afraid of wind and sun, and enjoy a certain level of comfort.

How often should the EV battery be replaced:

Under normal circumstances, the number of cycle discharges of lead-acid batteries is about 350 times, but considering that the larger the discharge current, the shorter the life of the battery, the deeper the discharge depth, and the shorter the life of the battery, the service life of the lead-acid battery is generally greater than 1-2 years, that is to say, it is normal to change the battery once every 1-2 years.

So when is it time to change the battery:

Clause. 1. The actual discharge capacity of the electric vehicle battery is less than 60% of the rated capacity, and the battery can be replaced if it cannot rise significantly after maintenance. This is because when the battery capacity is attenuated to 60%, the performance will be greatly attenuated, and all components will basically reach the aging state, and if not used properly, it is easy to lead to the risk of failure such as thermal runaway.

Clause. Second, when the electric vehicle battery is charged, you can clearly feel that the battery is seriously heated. Under normal circumstances, electric vehicle charging will heat up, but not serious, serious heating may be that the battery positive electrode will be seriously softened, the active material will fall off, the internal resistance will increase, and the impurity elements in the plate will continue to dissolve, so that the gas separation rate will increase when charging, the efficiency will deteriorate, and the heat generation will increase.

At this time, the electric vehicle battery not only discharges itself quickly, sometimes it runs out of power soon after charging, but also has potential safety hazards, and it is time to replace the battery.

Clause. 3. The battery is deformed, bulging, etc. The battery is bulging, etc., which can easily cause short circuits, open circuits, and even dangerous situations. Therefore, if the electric vehicle battery is deformed and bulging, the new electric vehicle battery should be replaced in time.

Summary: Electric vehicle batteries are generally replaced once every 1-2 years, and the battery should be replaced in time when the battery is aging, damaged, and bulging (deformed) to avoid unnecessary losses!
