How good is a lithium-ion battery electric car

Lithium-ion battery has long life, light weight, small size, good power performance and fast charging. 1. Long-life lithium-ion battery cells, the current good power 5C~10C cells, after the cycle life can be as high as 1500 times, there is still 70% capacity. In other words, the service life is as high as 8 years or more. After all, now the batteries of electric cars are used to make electric bicycles, which is really overkill. Of course, the author can guarantee the quality for you~ Ordinary lead-acid batteries, which are used for 2 years, then begin to attenuate the capacity, and the experience is too poor. 2. Light weight and small size. Because of the high energy density of lithium ion batteries, the unit volume is 5 times the capacity of lead acid. Therefore, with the same capacity, the volume of lithium ion batteries is smaller and the weight is lighter ~ 3. Power performance Well, the discharge characteristics of lithium-ion batteries have the properties of 1C charge and 1~10C discharge. Therefore, lithium-ion batteries can achieve real fast charging and standard power output, giving you a strong power experience. Lead-acid batteries are protected against deep discharge due to their memory. There will be 25% of the power that cannot be released, and a low point will seriously affect the life of the battery. Therefore, the capacity utilization rate of lead acid is 25% lower than that of lithium ion batteries. 4. Fast charging technology Li-ion battery pack, after being bigger, according to its 1C charging characteristics, it can fully realize the effect of 1 hour full charge. For example, a 20AH lithium-ion battery with a 7A charger will be fully charged in 3 hours. 30AH battery, fully charged in 4:30 hours. Of course, there are larger chargers, but the price/performance ratio will not be high. With the characteristics of lead-acid batteries, it is impossible to achieve the effect of fast charging. It can only be charged at a low rate. After 2 years of use, charging for up to 8 hours is common. Not to mention the waste of electricity, it may happen that the charger has been charging, but when discharging, there is no electricity at all. Lithium-ion batteries have activation-free features and no memory. In the use of lithium-ion batteries, it should be noted that after the battery is left for a period of time, it enters the dormant state. At this time, the capacity is lower than the normal value, and the use time is also shortened. But lithium-ion batteries are easy to activate, as long as 35 normal charge and discharge cycles can activate the battery and restore normal capacity. Due to the characteristics of the lithium-ion battery itself, it is determined that it has almost no memory effect. Therefore, users do not need special methods and equipment during the activation process of new lithium-ion batteries. Lithium-ion batteries have no memory effect and can be discharged 100%.
