Electric vehicles have become an important part of modern urban transportation, and the battery, as the core equipment of electric vehicles, has important functions and durability. EV batteries not only store energy and provide driving energy,Battery recycling but also take up about 30% of the total price of EVs. Nonetheless, in recent years, many people have reflected that EV batteries are not durable, and obviously the batteries that have just been replaced appear to have a significantly shorter range after less than two years of use.
For the durability of EV batteries, there are multiple factors to consider. The first is the number of charge/discharge cycles, i.e., the number of times the battery is fully charged, discharged and then filled.cylindrical cell assembly machine Generally speaking, the life of a battery is inversely proportional to the number of cycles; the more cycles, the shorter the life. Then the type and quality of the battery. The common types of batteries on the market today are lead-acid batteries, graphene batteries, lithium batteries and sodium batteries. Among them, lithium batteries rank second in terms of durability of EV batteries, and their service life can exceed 10 years.
Lead-acid batteries are the earliest type of batteries used in electric vehicles, but their lifespan is relatively short, generally 2-3 years. Graphene batteries are a new type of battery technology with high energy density and excellent cycle life,battery making machine but they are not widely used in the market yet. Lithium batteries, on the other hand, have become one of the mainstream choices for EV batteries due to their high energy density and long cycle life. Sodium batteries, as an emerging battery technology, have high energy density and cycle life, but currently there are still some problems in practical applications, which need further research and improvement.
In addition to battery type and quality, the use and maintenance of EV batteries also have an important impact on their durability. Reasonable charging method can prolong the service life of the battery. Overcharging or over-discharging can damage the battery, so it is recommended to follow the instructions in the battery manual. Proper temperature also has an impact on battery life. High temperatures will accelerate the aging of the battery, while low temperatures will affect the performance of the battery, so pay attention to temperature control when storing and using the battery.
In the face of the problem of non-durable electric car batteries, consumers can take some measures to extend the life of the battery. Choose battery products with good reputation and quality assurance, and avoid buying low-quality batteries. Pay attention to reasonable charging and discharging in daily use and avoid overcharging and discharging. In addition, timely battery maintenance and care is also the key to extend battery life. Regularly checking the battery's connecting wires and insulation, and cleaning the dirt and corrosion on the surface of the battery can effectively reduce the loss of the battery.
To summarize, the importance and durability of electric vehicle batteries should not be ignored. Choosing the right type and quality of battery, reasonable use and maintenance of the battery can extend the service life of the battery. In the future, with the progress of science and technology and the application of new battery technology, it is believed that the durability of electric vehicle batteries will be further improved, injecting more vitality into the development of electric vehicles.
