①Environmental protection: the whole production process is clean and non-toxic, and all raw materials are non-toxic;

②Small size: the energy density of lithium batteries is higher, and the size of lithium batteries is smaller under the same capacity, and manufacturers can free up a large space to implement some other functions when designing vehicles;

③Longer cycle times: The general lead-acid battery decays severely after one year of use, and the user needs to maintain and replace the battery regularly. Lithium batteries are basically maintenance-free within three years under normal use intensity.

④With the feature of activation-free: When using lithium batteries, please note that the battery will enter the dormant state after being left for a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened. But the lithium battery is easy to activate, as long as the battery can be activated after 3-5 normal charge and discharge cycles, and the normal capacity can be restored. 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 of lithium batteries needs to be improved: compared with lead-acid batteries, lithium batteries are much less resistant to fluctuations in charging and discharging. For current high-power vehicles, one of the major symptoms of the ineffective use of lithium batteries is this, which leads to durability. decline.

②There is a danger 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 generated 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 break and cause Liquid leakage, fire, or even explosion. This problem can be solved by choosing a lithium battery that matches the motor’s model and specifications, and prevent unauthorized modification of electric vehicle motors, electric vehicle overweight, and abnormal climbing of electric vehicles that cause high current discharge. At the same time, consumers must remember that they must use the original matching charger, and must not purchase chargers that do not match the model specifications or are of inferior quality.

③ Lithium battery electric vehicle matching problem: According to the survey feedback of the editor of the global electric vehicle network, the current auxiliary motor and other external equipment related to lithium battery electric vehicle are not mature enough.

④High price: The current price of lithium battery electric bicycles is generally a few hundred to one thousand yuan higher than that of lead-acid battery electric bicycles, so it is difficult to get consumer recognition on the market. Lithium batteries are lightweight, environmentally friendly, and will not cause environmental pollution after being discarded. Once the application technology is mature and the market sales increase, the price of lithium battery electric bicycles will come down.

The above are the advantages and disadvantages of the mature technology of lithium battery electric vehicles and lithium battery electric vehicles. Develop good habits, lithium battery electric vehicles will have a longer service life and better experience.
