Are lithium batteries mature for use in electric vehicles, and what are the advantages and disadvantages?
As electric vehicles are an essential tool for people’s daily travel, the safety of lithium batteries has attracted more and more attention. As an important part of the power supply of an electric vehicle, the safety of the motor and lithium battery is the most fundamental guarantee for an electric vehicle. Planning a reasonable safety distance for the battery cell bracket to supply the battery cell heat dissipation path is conducive to the safe heat dissipation of the lithium battery.
Are lithium battery electric vehicles experienced? At present, the technology of small lithium electric vehicles can meet the application requirements. In terms of safety, the power lithium battery technology of electric bicycles is actually fundamentally sophisticated and fully meets the conditions for market promotion. Lithium batteries have high requirements for consistency in the process of battery packs. The higher the consistency of the battery, the safer and longer life span, but now many companies have encountered technical bottlenecks in battery consistency.
In fact, lithium battery safety incidents are rare in foreign markets. The recent growth of lithium battery companies is very hot. From another perspective, the emergence of incidents may be a merit. On the one hand, it can make the skills and talents not so experienced, and then develop hastily. Power lithium battery companies are resigned to their fate, and at the same time, companies with sophisticated skills have gradually been recognized by the market.
Advantages and disadvantages of lithium battery electric vehicles. 1. Strengths, ①Environmental protection: The entire production process is clean and non-toxic, and all raw materials are non-toxic; ②Small size: The lithium battery has higher energy density, and the lithium battery is smaller under the same capacity. The manufacturer can free up when planning the vehicle. To complete some other functions; ③Longer cycle times: The general lead-acid battery decays severely after one year of use, and users need to protect and replace the battery regularly. Lithium batteries are fundamentally protected from protection within three years under normal use intensity.
④With the feature of activation-free: When using lithium batteries, please note that the battery will enter a dormant state after being left for a period of time. At this moment, the capacity is lower than the normal value, and the use time is also shortened. But the lithium battery is very simple to activate, it only needs to pass 3-5 normal charge and discharge cycles to activate the battery and restore the normal capacity. Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect. Therefore, the user does not need special methods and equipment during the activation process of the new lithium battery.
2. Disadvantages: ①The power performance of lithium batteries needs to be improved: compared with lead-acid batteries, lithium batteries are much less resistant to shaking in terms of charging and discharging. This is one of the major symptoms of current high-power vehicles that cannot be used effectively. , Resulting in decreased durability. ②There is a risk of explosion: when the lithium battery is charged and discharged with high current, the internal temperature of the battery continues to heat up, the gas that occurs during the activation process expands, the internal pressure of the battery increases, and the pressure reaches a certain level. If the outer shell is damaged, it will rupture and cause Liquid leakage, fire, or even blasting.
③ Lithium battery electric vehicle matching problem: According to the survey feedback of the editor of the global electric vehicle network, the external equipment such as the motor related to the lithium battery electric vehicle is not so sophisticated. ④High price: The price of lithium battery electric bicycles is currently several hundred to one thousand yuan higher than that of lead-acid battery electric bicycles. Therefore, it is difficult to get consumer recognition on the market. Lithium batteries are lightweight, environmentally friendly, and will not cause environmental pollution after they are discarded. Once the application skills are mature and the market sales increase, the price of lithium battery electric bicycles will come down.
The above are the pros and cons of lithium battery electric vehicles and the advantages and disadvantages of lithium battery electric vehicles. Develop good usage habits, lithium battery electric vehicles will have a longer service life and better experience.
