Why is electric car battery life? What is caused?

Nowadays, many electric car consumers have problems with electric vehicles they use. It is still not good to use the battery. It is always considered that the battery quality is not as good as before, why is the battery quality becomes more and more? Some electric vehicles consumers have sent information from various self-media, venting the complaints of the battery manufacturers .

indeed, the battery is one of the core components of electric vehicles, and the quality of the battery directly affects electric vehicles. Drive mileage. For consumers, an electric car is an important property at home.

You can imagine that only one or three thousand yuan of income is only one or three thousand yuan, an electric car may be a valuable home that can be purchased in a few months. After purchasing, the electric car is not far away, or it is close to the shelf life, or just replaced a group of batteries between 400-500 yuan, consumers will definitely feel very uncomfortable. Therefore, the conflict between consumers and dealers will inevitably explode.

In fact, the electric car is not far from or has such a problem with the so-called electric vehicle quality, the reason is a lot, the run is not far a specific performance, but there are many essential things inside. Here, we conducted a systematic analysis of the quality problems that the electric car was not running. It is blamed for nine aspects: 1 is that the reusability of lead is reduced to life, causing electric vehicles that have no capacitance in the predetermined shelf life.

Fast attenuation. About lead use, it is generally repeated 2 times. The industry is also known as the secondary battery, but the current technology can refine the waste lead multiple times, use multiple times, this is regenerated lead.

Due to the use of regenerative lead, the company's cost is greatly reduced, but it also affects the quality of the battery, which affects the reduction in the number of battery charges. In theory, the dynamic lead-acid battery cycle life (the number of charge and discharge) is 230 times, but it also looks at how consumers use. When used, life can increase by about 10%, and use must not be reduced by 10% up and down.

2 II is the national mandatory requirements of heavy metals added to the battery, and must not exceed 0.1‰To one of the ratios, thereby limiting the battery life, leading to one of the reasons why electric car moving battery is not far away. Why is the battery quality before 2011? Tell you here, former battery companies in order to add product life, give battery power, and let the product quality on the new stairs, the company has added a large number of heavy programs such as cadmium, etc.

in the battery pole. Since lead has added these heavy metals, greatly add the activity of the plate, so that the product quality has a qualitative leap. However, since these cadmium-containing power storage batteries are recovered, there is no good treatment, and a large number of waste contains these heavy metals have flowed into the soil, and the environment is severely polluted after the river water.

Cadmium rice and other accidents also can't get off with the power lead-acid battery. Therefore, the country has undergone strict control of the addition of heavy metals in the lead-acid battery since 2012. In the next few years, the heavy metal in the dynamic lead-acid battery has also affected one of the reasons why electric cars running not far.

3 Third, the electric vehicle is too heavy, accelerates the consumption of the battery, causing the battery's full number of times. Everyone understands that electric motor vehicles are selling, this vehicle is to meet the consumer's motorcycle complex, which is a sales strategy for the new profit for manufacturers. Regarding these electric cars, we roughly estimate the weight of the vehicle body (including battery), between 60-80 kg, plus the driver, plus one person, the electric vehicle must reach more than 200 kilograms.

If you encounter a traveler of obstacles such as climbs, the battery discharge is very large. According to theory, 48V20AH can drive 40 kilometers or so, but actually can't do it. And each time it is less than 30 kilometers, it must be charged once.

After a while driving, the electric vehicle has a quick increase in battery life, thereby speeding up the battery life. 4 4 is the quality of charger. Now, many of the vehicle manufacturers take the bare car sales, and the work of assembling the battery will make the dealer to be taken.

In order to reduce costs, the maximum profit is maximized, some dealers can purchase low-configured chargers, and there are many problems with poor charging charger. Since these low-priced chargers have problems with technical design defects and component quality, the quality of the battery is seriously injured during the charging process. The battery is not using bad, but a problem of charging mode is contrary.

5 5. It is that consumers use improper problems that cause battery life. Summer is overcharged, the problem in winter is due, causing the battery life of the electric car to decrease, thus making electric cars not far away.

Everyone understands that the battery is most afraid of being filled in the summer, which is also the problem that the battery is burning. Since the charger is designed to exhibit the functional defects in the overcharge protected plate (these are poor quality chargers to make a disaster, so that the battery will continue to charge after full, it is destroyed for the battery's diaphragm. The life of the battery affects the battery, which causes the battery diaphragm to be broken down and short-circuit combustion.

In the winter, because of the cold reasons, the battery is not full, the battery is not far away. 6 is after depth discharge, that is, after the electric car battery is used, continue to drive, causing the battery to be severely lost, often use great to shorten the life of the battery. After the battery is lost, consumers should know how to make up in time, but these problems have occurred because there is no sense of mind.

77 is a fast charge method, such as coin charging, using large current charging. The lead-acid battery should be charged in a short time, it must be in exchange for life. Due to the characteristics of the lead-acid battery, it is not possible to use a fast charge.

Now, individual phones such as charging for 5 minutes, 2 hours, very harmful to the battery. Let the quality of the battery can be maintained in the best state, in addition to using the battery to minimize the use, it is best to take the trickle charging mode. 88, electric car is not used for a long time.

The battery is placed for a long time, the battery is absent, the driver is used, and the fast mode is charged immediately. It has a big damage to the battery quality, which not only affects the life of the battery, but also causes the life of the battery. shorten.

999 is the problem of electrical dendency. Electric vehicle motor quality is not good, magnetic steel sheet in the motor is demagnetized, resulting in serious decline in the performance of the motor. Similarly, the same electrical energy is transported.

Due to the demagnetization of the magnetic steel sheet, the electric energy used by the motor cannot effectively convert the corresponding kinetic energy, causing the motor quality to consume a large number of batteries. At present, the electric car of the lead-acid battery is basically used to have a brushless and odorable motor, and the effect of the motor is only about 72%. Such a motor is maintenance-free, low noise; but the disadvantage is that the energy consumption is large, the effectiveness is lower.

Motor demagnetization causes a large amount of loss in batteries, and it is easy to neglect. .
