How many kilometers does pure electric car change the battery?

Cycle life of electric cars depends on the motor. Drive motor is different. It costs a lot. If using a DC motor, the motor car power can directly supply, the use of this machine adopts thyristor controller for speed regulation.

Battery life is "dry storage life" and "wet storage life". These two concepts is only for the battery self-discharge in terms of size, not the actual service life of the battery. Real life means the battery actually use the length of time. For a battery, the battery life is characterization of nominal capacity is given working time (and the size of the discharge rate).For secondary battery, the battery life points to charge and discharge cycle life and wet on the service life of two kinds, charge and discharge cycle life, is an important measure of the secondary battery performance. Subjected to a charge and discharge, is called a loop (or a cycle).

Under the certain charge and discharge system, battery capacity fell to a specified value, before the battery tolerated cycle count, called secondary battery charge and discharge cycle life. The longer the charge and discharge cycle life, the better the performance of battery. In the current commonly used secondary battery, nickel cadmium battery charge and discharge cycle life of 500 ~ 800 times, lead-acid battery 200 ~ 500 times, lithium ion batteries600 ~ 1000 times, zinc silver battery is very short, about 100 times or so.

The secondary battery charging and discharging circle life and discharge condition such as the depth, temperature, charge and discharge formats. The so-called "discharge depth" refers to the capacity of the battery release percentage of rated capacity. Reduce the depth of discharge (namely "shallow discharge"), the secondary battery charge and discharge cycle life can be greatly extended. Wet on service life, is one of the important measure of the secondary battery performance. It refers to begin after joined the electrolyte battery charge and discharge cycle until the charge-discharge cycle life end time (including in the process of charging and discharging cycle battery discharge in wet on time).Wet shelve the longer service life, the better the performance of the battery.

In at present commonly used batteries, nickel cadmium battery wet on service life is 2 ~ 3 years, 3 ~ 5 years lead-acid battery, lithium ion battery 5 ~ 8 years, zinc silver batteries, the shortest is only about 1 year. In addition, the performance of the battery is: the low temperature performance, overcharge resistant ability, safety, etc.

How much money the electric car battery changes, how long is the battery life - price

The electric car battery 2

New energy vehicles is developing by leaps and bounds, according to official figures, 2014 national sales of new energy vehicles 75000 vehicles, including sales data ranked first in Shanghai, is expected to more than 200000 vehicles in 2015.New energy cars run faster and faster, as the "heart" of the battery, however, became foot-draggers, chaos, the battery should be according to the calculation of the price. Once the electricity around 2000.Generally 150 km car, electricity is 20 to 25 degrees.250 kilometers of 40-45 degrees of electric car.

Looks like the electric car battery changes also very not easy, battery maintenance has become a popular now "obstacle" of electric vehicles. This is the small make up to introduce electric vehicles in electricity

Pool how many money, how long is the battery life, for an electric car, its battery life mileage, the nature will bring more convenience, in which the greater the range means that the frequency of charging the lower

Actual decided the service life of the electric car, in addition to the motor, the second is the battery; General motors has quality assurance, normal use; But if you use the battery, charging will greatly reduce the service life; So make an introduction for the battery using specialized; Here is the use of batteries, battery should be charged when stored in storage after, in a month or so out discharge or use one to two times, and then charging continue to store; So to extend the service life of battery; General new battery charged three times before the best in 8 to 12 hours, and later in six to eight hours;

Battery charging fast and slow doesn't matter; The key is to discharge time. Discharge time is long can continue to use; As long as it is able to charge and discharge battery is still can continue to use; If can buy domestic brands; If they can identify quality fit and unfit quality, also can be small and medium-sized manufacturer of choose and buy brand products; This cost-effective;

General battery life decided by the number of charging and discharging; General repair, renovation of battery charging times at about 50 times, so to tell you, when buy warranty for three months, or six months; A warranty must make is not long; Normal manufacturer production of battery charging, discharge times in 100-180 times or so; Use period in a year or two years or so; Good manufacturers of battery charging, discharge times around 200-300;Life in two to three years or so; Import, original battery charge and discharge can reach more than 500 times, use fixed number of year is longer;

The most ideal state should be nearly run out of battery power when recharging, best; General the most taboo is a battery charge and discharge; Simply follow the two principles, will be able to maximize the use of and play out the biggest battery service life cycle.

Service life is generally 1 to 2 years, good 2-4 years.

A little car maintenance experience knows, battery, belong to the consumable parts of traditional gasoline vehicles, the average life expectancy of 3 years or so, the need to be replaced. A small car battery has to be a few hundred dollars, often hundreds of kilograms of battery electric vehicles, not expensive? A few years hard charging saved the money, is not enough for battery! People with similar views and many, refer to the service life of battery this accessories, seems to have some truth.

A, Power battery classification of

Currently, it used in automobile power battery, roughly divided into lead-acid batteries, lithium batteries, nickel metal hydride batteries. The Ni-Mh batteries only Toyota of plug-in electric hybrid, not suitable for as a separate power source; Lead-acid battery is mainly used in low-speed electric cars, that is, as the saying goes, "old man music"; Lithium battery electric vehicle power battery is the most widely used. According to different materials, the lithium battery is divided into many kinds of currently used mainly for mature ternary lithium battery and lithium iron phosphate batteries. Using lithium battery models on the market are the two basic cell.

Might have to dog lead-acid, nickel-metal hydride is a person's carnival, Toyota lithium battery is king!

Let's start with lead-acid battery. In fact, it is general car battery, after more than pieces of series/parallel directly as a source of power. This type of battery discharge current (resulting in a smaller as a result, we often say "boring"), cars run fast, probably the fastest pace in about 60 km, life is short, about 3 years period must be replaced. Advantage lies in production of low threshold, the price is cheaper, less to protect circuit and equalization circuit requirement, basically manual mill production. The disadvantage, slow speed, low power, short life.....Meet the requirements of national new energy car didn't use of lead-acid batteries. But the impression that this battery in people's minds, many were directly transferred to lithium battery.(especially we run the car at low speed large Shandong)

Said the lithium battery, lead acid, have skill you don't go

And two kinds of lithium ion battery, also have different "temper", said the ternary lithium battery first. More representative of the tesla, baic E200EV eQ, Jjianghuai IEV5, Chery, etc., is characterized by high energy density, under the same volume weight, large capacity of electricity; Battery good consistency, mature production technology. Such batteries, theory circle life is controlled in 1500, the actual use, fully charge and discharge cycle in more than 800 times, and control the battery discharge from 25% to 75% of the state, the actual use can reach more than 1200 times. See here, do you want to say, 800, 1 day 1 time, not less than three years? Here, I want to explain the concept of full circulation. Refers to a full charge, then it finished, is a cycle. If use from 100% to 75% every day, and then filled with, then 4 genius is a complete cycle, life can be up to 10 years. In general ternary lithium battery electric vehicle range of 200 km, one complete cycle of the actual can travel 180 km, 800 - cycle can go 144000 kilometers, including normal attenuation, 120000 km is also no pressure. Day 1, 60 km is under the use frequency of use for 10 years. And if put attention to a pale imitation, maintain good battery, a 1200 - cycle, 150000 kilometers, the basic cover the service life of a family car, that is to say, with car battery life, do not need to replace the battery the whole cycle.

With car battery life, and the whole cycle do not need to change battery.

We say again the lithium iron phosphate batteries, representative models have BYD, BYD Tang Qin, the E6, teng potential, Jianghuai IEV4.The characteristics of this kind of battery is long cycle life, can reach more than 2000 cycles; Charge and discharge ratio is high, that is, there can be more charge and discharge current; Good safety, bending piercing high temperature. The disadvantage is that the energy density lower, the same life need to use more batteries, increase the vehicle weight and cost; Consistency is poor, need better battery management system; Attenuation is more noticeable at low temperature 0 ℃ capacity will reduce about 10%, when the capacity decreases about 30% - 20 degrees.

In the winter, the same car showed difference in north and south .Beijing folk singer Mr Matte for pure electric vehicles, 2000 cycles have been surplus. Even for life is only 70 km of qin, a 2000 - cycle can also support Qin Chun electric driving 140000 km, including using gasoline mileage, the service life of the whole car is also no problem.

Third, it really wrong

And friends may think, the car without the car, once the battery problems, on how to do? Whether to pay high maintenance cost? First of all, current countries requires new energy car key components (battery, electric control, electrical) provides not less than five years or 100000 kilometers quality assurance, and since 2016, provide no less than eight years or 120000 kilometers quality assurance. In this period, repairs are completely free, and some vendors to provide more than the long warranty period, such as BYD, batteries lifetime warranty. So, after confirmed, the battery failure? If you want to change the battery pack, really want to change, but the cost is not in the minds of many tens of thousands of pieces, because they don't need to change the whole battery. Just replace the corresponding one or a few fault battery is ok. And a battery alone are the most expensive but also a few hundred dollars, on working hours, the few thousand dollars, should be cheaper than a fuel car maintenance .At this point, the electric car will have high use process replacement battery cost concerns can dissolve. I can rest assured choice suits own new energy cars, the whole process of using almost do not need to pay any additional costs for the battery, you can enjoy the experience of new energy vehicles of different.

All the above is today introduction for electric car battery, which can use for a few years. At present, the country requires new energy car that key components (battery, electric control, electrical motor) provide no less than five years or 100000 kilometers quality assurance, and since 2016, provide no less than eight years or 120000 kilometers quality assurance. In this period, repairs are completely free, and some vendors provide longer warranty period, such as BYD has battery lifetime warranty. It is believed that all of your questions have a certain understanding.
