It has subsidiaries (branches) such as Changxing Tiandu Power Supply, Jiangsu Jinchangxing Power Supply, Xinyi Shenghua Power Supply, Jiangsu Jinjie Electronics, etc., to realize a complete industrial chain of battery assembly, plate production and pulse rechargeable battery manufacturing. Nissan electric vehicle battery 70,000, its Jiangsu Jin Changxing power supply in 2014 through the first batch of acceptance by the Ministry of Environmental Protection.

Panasonic batteries look around 800 and are the best.

Ma'anshan is better, and the general use of Tianneng is about 600.

If you replace the battery at a regular physical store that sells battery cars, you can choose one closer to home. In this way, after-sales will also be guaranteed and relatively convenient.

Precautions for replacing the battery:

1. Pay attention to the date on the battery when changing the battery.

2. Check whether the electric vehicle battery product logo is complete.

3. The voltage of the new battery should be consistent with the original, and the capacity can be different, but increasing the capacity can generally extend the driving range.

4. Be sure to ask for a warranty and a warranty period (15 months for small batteries and 12 months for large batteries).

The first thing to look at is how old is your electric car? Many batteries and electric vehicles do not match, you need to use a matching battery, basically it is also larger, there are this kind of batteries where battery cars are sold, you go there to buy it.

If the battery of the battery car is not of good quality, it is easy to charge**, and the service life is not long. If you want to change the battery, it is better to find a regular after-sales service, and if there is a problem, you can find them to be responsible, and the quality of the battery should be better in the regular store. The garage may be refurbished and not used for long.

I must have chosen the after-sales wow, at least the regular after-sales store. Generally speaking, they will not smash their own signboards, and the charge for repairing the car outside to replace the battery is not because the battery capacity is larger than that of the after-sales service? I guess the cost is higher than the one in the store.

Now there are a lot of battery cars, so there are more places to change the battery, if you don't have the old battery, it will be more expensive than one hundred or two hundred, because now the old is trade-in, and many places to change the battery frequency, you can also go to the place where you buy a car.

Now many places electric vehicle batteries can be trade-in, in principle, it should be a little lower than the after-sales **, because your old battery has been discounted, you said that the after-sales is cheaper than the place where the battery is sold and the electric car is repaired outside200, this is not heard of in our place, our battery batteries are to repair the electric car or replace the battery, the total price of the old for the new is only more than 100 yuan, so I personally feel that it should be cheaper than the after-sales.

Go to the after-sales service to change, the quality is guaranteed, and the problem is easy to solve.

You can go to you to buy a car** for another one.

Hello, dear, I am very happy to answer for you, if you change the battery in a single battery, one is about fifty or sixty yuan. If it's a group of four, it's basically around 200 yuan. If it is a group of five batteries, basically one piece costs about 100 yuan, and the whole group costs about 500 yuan.

If it is a group of six batteries, a single one is basically 120 yuan a piece, and the whole will probably be more than 700. Under normal circumstances, a battery can be bought for 300 or 400 yuan, and if it is a relatively high-end battery car, it will cost about 1000 yuan to replace a battery.

Hello electric vehicle battery precautions 1, part of the update of the electric vehicle battery replacement battery new battery must be completely consistent with the original battery category, specifications, model, in addition to voltage, capacity, power, charging system must be consistent with the original battery, and the primary battery pack should be in the early stage of life, at least should not be in the late stage of battery life. The whole group of batteries is in the late stage of life, and it is no longer meaningful to replace individual single batteries, and it is best to replace them all after the end of the life of the whole group of batteries. Regardless of whether the battery of an electric vehicle is replaced as a whole or individually, it should be matched with the original charger and controller.

2. If the whole group replaces the whole group and the battery category changes, the characteristics of the controller and the charger are involved, which must be consistent with the characteristics of the battery, such as charging rate, charging end, discharge and other requirements. Finally, I would like to remind everyone to be sure to buy a branded battery. Generally speaking, there are 4 reasons why a battery is damaged:

Water loss, vulcanization, imbalance, thermal runaway (drum filling). And the first two items account for almost 97% of battery damage in the market. Therefore, it is very important to choose a well-known brand electric vehicle battery that has passed the national test.

It can reduce the probability of replacing the battery of your electric vehicle, so that your electric vehicle battery can last longer.

The common electric vehicle batteries on the market today are lead-acid batteries and lithium batteries. As for whether to buy lead-acid batteries or lithium batteries, it mainly depends on your own needs. Because whether it is a lead-acid battery or a lithium battery, they have their own unique advantages and disadvantages, so there is no better statement, can only say which is more suitable for themselves, after all, everyone's use is different, you can refer to the advantages and disadvantages of lead-acid batteries and lithium batteries, combined with their actual use, choose a more suitable electric vehicle battery.

Here are the pros and cons of each:

Advantages of lead-acid batteries:

1. Good safety performance. Lead-acid batteries are easy to feed, let you fall and beat, repair a little, and you can continue to use.

2. Cheap. Lead-acid battery** is about 1 3 of lithium-ion batteries, which shows that its ** is very low.

3. Reversible repair. Lead-acid batteries can be used strongly, after the use of bad can go to the electric car store to trade in the new, make up the difference in price can be replaced with a new set of batteries, the loss is minimized, is a big benefit for the user. The lead in the battery can also be reused, reducing environmental pollution.

Disadvantages of lead-acid batteries: large weight, limited battery capacity, short life, lead-acid batteries are generally within 400 times of deep charge and deep discharge, and the life span is about three years.

Advantages of lithium-ion batteries:

1: Light weight and small size. The volume of lithium-ion batteries is 2 3 of the volume of lead-acid batteries, and the weight is about 1 3 of the weight of lead-acid batteries.

Lithium-ion batteries of the same volume have a higher capacity than lead-acid batteries, and the reduced weight makes electric vehicles lighter and has an increase in range by about 10%.

2: Long life. The average life of lithium-ion batteries is about 4 years, which is about one year higher than that of lead-acid batteries, with more than 500 times of charge and discharge, no memory of battery use, and strong shock resistance.

3: Overcharge resistance, good charge and discharge resistance. Lithium-ion battery At normal temperature, lithium-ion battery can be charged continuously for 48 hours without accidents such as battery expansion, leakage and rupture, and the capacity is kept above 95%. And under the dedicated charger, it can be charged and discharged quickly.

Disadvantages of lithium-ion batteries:

The production cost of lithium-ion batteries is high, and the labor cost of production equipment accounts for about 40% of the production cost, which is about three times that of lead-acid batteries. Its three times the cost performance is not high, it gives people a flashy feeling, and the lithium-ion battery can not be used, it can only be thrown away, or find a place to bury it, after thousands of years, future generations will dig it out and be an antique.

Comprehensive electric vehicle battery product quality, after-sales service and these aspects, recommend a few good lead-acid battery brands: Tianneng battery, Changxin battery, mythical battery, Mantingfang battery.

Lead-acid wants to change to lithium battery.

Lithium batteries want to change lead-acid.

There is no problem with the former, and there can be trouble with the latter.

Lead-acid for lithium battery, the same capacity, the car is lighter, the battery is smaller, the performance is not affected, and the battery space is sufficient.

Lithium battery for lead-acid, the same capacity, means that the volume of the battery has doubled, the weight has also increased, and the performance of the car with more load out of thin air is affected, and the most important thing is that the space for lithium battery can not be put down with lead-acid of the same capacity. The electric car can be arranged in such a place?

If you change to a small capacity of lead-acid, then the mileage of the car will definitely drop sharply, because the car is designed according to the capacity of lithium battery, the capacity of lead-acid has become smaller, the small horse-drawn cart, the car is full of tired horses, and the battery life has become significantly shorter.

Leadate is present in the form of. The hydrates of all lead oxide(iv) oxides, with the exception of n-lead-acid, are not readily available in a determined composition. Insoluble in water.

Hexahydroxyleadic acid is red. It is weakly acidic and unstable, and its salt is relatively stable. Lead-acid can be hydrolyzed by lead(iv)ate or by the addition of water to produce a colloidal precipitate.

Hexahydroxyleadic acid can be prepared by the reaction of potassium hexahydroxyleadate with acetic acid for the preparation of other lead compounds (mainly lead salts).

Lithium battery is a kind of primary battery that uses lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution, which is different from a rechargeable battery Lithium-ion battery is different from lithium-ion polymer battery. The inventor of the lithium battery is Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements.

Therefore, lithium batteries have not been applied for a long time. With the development of microelectronics technology at the end of the twentieth century, the number of miniaturized devices is increasing, and high requirements are put forward for power supplies. Lithium batteries have then entered the stage of large-scale practical use.

Summary. All of them are changed.

The battery is directly replaced by the manufacturer, and the requirement is that only a whole group of batteries can be replaced, that is, the whole group of batteries is replaced, and each group of batteries has a fixed code, if you change a piece privately, it will lead to the manufacturer no longer replace, and only the customer will bear the consequences if there is a problem in the future.

The most important thing in the battery is the internal resistance parameter, the longer it is used, the greater the internal resistance of the battery. In other words, the biggest difference between the new battery and the old battery is that the internal resistance is different. The internal resistance installed in the same batch of electric vehicles should be basically the same.

Extended information: The state of power loss refers to the fact that the battery is not charged in time after use, and the battery is prone to sulfation when the battery is lost, 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 to prolong the service life of the battery.

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.
