Why is the battery becomes less durable? What is the cause of not durable?

Many motor vehicles and electric car users may feel that the current battery is not before, the previous battery can basically run for 3 years without problems, many electric cars do not have to change the battery for life, and more people have batteries It can be used until ten years. Now the battery can be used in a year or two, and some can only use half a year. Why is the battery soon now? First, the battery is not allowed to add cadmium, the battery is more environmentally friendly.

According to the "battery industry access conditions" established by the Ministry of Industry and Information Technology, the Environmental Protection Department, Industry Association, clearly stated that the existing cadmium content is above 0.002% or a arsenic content of more than 0.1%, and its lead-containing component is produced in 2013.

Before December 31, it was eliminated. The battery companies strictly abide by the state stipulate that the batteries produced after 2014 meet the national standards, and the cadmium arsenic content in the battery is strictly controlled. Some companies have even launched a battery that completely cadmneric arsenic.

It is objectively used to use life and life. Stability has a certain decline, but from the long-term perspective of national development: not battery is not good, but the battery is more environmentally friendly! Second, the battery uses internalization into production process, reducing environmental pollution. From 2014, according to the requirements of "battery industry access conditions", the production of electric vehicle batteries must implement internalization into production processes.

Significant advantages of internalization into production processes are to reduce environmental pollution during production, while producing employees can better protect. However, it is also apparent to the effect of the effect that has not been previously improved. Third, electric vehicles are getting heavier, power consumption.

Before 2014, the simple electric car in the market is increasing, with people's requirements for comfort, the proportion of luxury in the market is getting bigger and bigger, and the weight of the luxury has a significant new increase. Power consumption is increased, the mileage and service life of electric vehicles will fall. Fourth, electric vehicles are getting faster and faster, motor power increases.

The electric vehicle motor sales in the market in the market is relatively small, and the small power is 250W, high power is 500W. In these years, the electric vehicle is pursuit of pursuit, the motor power has increased, and the 800W motor and 1200W motor are very common. The larger the motor, and the damage to the battery is increased.

V. Quick charging station all over the street alley, large current charging to complete the battery. In these years, the streets and alleys are all over the fast charging station.

If you choose a quick charging station to charge the electric vehicle to charge the electric car, more use will lead to water, which will cause battery drums and battery life. Sixth, inferior charger is flooding, battery is sacrificial. In these years, the competition in the charger industry is increasingly fierce.

Many charging manufacturers have a sharp reduction. For new market competitiveness, reduce costs, reduce prices, and sacrifice quality, causing batteries to become increasingly contracted due to inferior chargers. 7.

The battery industry has a big price war, a small factory product. Since 2014, the battery industry has continuously burst into a tragic price war. Many battery plants use the No.

1 lead used before the cost using the second lead. The battery barely supports the shelf life, and the life is declining. At present, all major battery manufacturers are studying the latest technologies.

Finding ways to improve battery quality. According to common sense, the quality of electric car batteries should be getting better and better, but now the battery is indeed more pressure, the battery is also We understand, understand long live!.
