What are the advantages and disadvantages of lithium battery electric vehicles

What are the advantages and disadvantages of lithium battery electric vehicles? How many types of lithium battery electric vehicles are currently on the market? Lead-acid battery electric vehicles are still the best-selling ones, but there are also many fields that have begun to analyze lithium battery electric vehicles. Lithium battery electric vehicles are taken out of context. Simply put, they use lithium batteries instead of lead-acid. Compared with lead-acid batteries, are lithium batteries for electric vehicles good? It is really enterprising, do dealers say that? The country vigorously advocates energy saving, green and environmental protection. When it comes to lithium batteries for electric vehicles, are they good? Everyone’s The concepts are very different. Lithium batteries are lighter than lead-acid batteries and have a longer lifespan, but the price is very expensive, but what is better? Once again, no one seems to be able to answer. This picture is provided by the registered user’s silent time. The copyright description reflects the advantages and disadvantages of lithium battery electric bicycles. 1. The lithium battery has long life and light weight and small size. The power performance of lithium battery electric bicycles is similar to that of lead-acid batteries (simple electric bicycles). , Charging for 6 to 8 hours, depending on the battery capacity, it can run 30 to 45 kilometers, as long as the weight of the lead-acid battery is about 1/5, the lithium battery electric bicycle is the biggest advantage of longevity. Disclaimer: The price of lithium batteries is just to look at the appearance. In fact, carefully calculate the cost of lead-acid batteries and ordinary lithium batteries. Now ordinary lithium batteries are protected for two years and lead-acid batteries are protected for one year. 2. Lithium batteries have non-activation characteristics. When using lithium batteries, you should pay attention that after the battery is placed in a dormant state for a period of time, the capacity is lower than the normal value and the use time is also shortened. But the activation of the lithium battery is very simple, only through 3-5 normal charge and discharge cycles to activate the battery, the normal capacity. Due to the characteristics of lithium batteries, they have almost no memory effect. Therefore, the user's new lithium battery is not a special method and equipment during the activation process. 3. No memory effect Customers are constantly worried about the memory effect of the battery when charging lead-acid batteries and nickel batteries. For example, lithium batteries, we can Panasonic, lithium batteries have no memory effect. If you still have customers who don’t know how to charge lithium batteries, please check the following. Defects of lithium battery electric vehicles 1. The price of lithium battery electric bicycles is too high. Because the current price of lithium battery electric bicycles is several hundred to 1,000 yuan more expensive than lead-acid battery electric bicycles, it is difficult to gain customer recognition in the market. Lithium batteries are light in weight, 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 electric bicycles with lithium batteries will decrease. 2. Too long charging time for lithium batteries will be counterproductive. Lithium batteries or chargers will actively stop charging during charging. There is no so-called trickle that nickel chargers continue to charge for 10 hours. In other words, assuming your lithium battery is fully charged, the charge on the charger is also white. Although we cannot guarantee that the characteristics of the battery's charge and discharge maintenance circuit will never change, and the quality is fully guaranteed, your battery will be at risk of long-term marginal loss. This is another reason why we oppose charging for a long time. In addition, in some electric vehicles, if the charger is not removed after charging for a period of time, the system will not only stop charging, but also start a charge-discharge cycle. Manufacturers may have their own goals, but this is clearly not conducive to battery life. Therefore, when buying a lithium battery electric vehicle, you should consult the company or dealer to do a good job of maintaining the lithium battery. 3. Lithium battery power needs to be improved. Lithium batteries have much worse jitter ability than lead-acid batteries during charging and discharging, and are not useful for current high-power cars. The choice of lithium batteries is also a major drawback here, resulting in decreased durability. . 4. Lithium battery safety issues are highlighted. Lithium battery safety needs to be improved. The danger of fire, melting and explosion of lithium batteries still exists. A vehicle collision may cause a breakthrough in the positive and negative data of the battery. When the braking energy is quickly charged to the battery, the instantaneous ultra-high current will cause the battery to short-circuit, increase the temperature, and cause an explosion. The cause of the fire is collision, short circuit causes lithium ion precipitation, contact with air will cause fire, no wind.
