How good are lithium battery electric vehicles? Do you know how much lithium battery there is?
With Tesla, BYD and other car manufacturers launching more electric cars, lithium battery electric vehicles have entered our lives all of a sudden. Why lithium battery electric vehicles have become the future, and how lithium battery electric vehicles can enter the lives of ordinary people? Today, CSIT electric vehicle lithium battery manufacturer will tell you about the advantages of lithium battery electric vehicles.
On the market, the most popular ones are still lead-acid battery electric vehicles, but many regions have begun to introduce lithium battery electric vehicles. As the name suggests, lithium battery electric vehicles simply replace lead acid with lithium batteries.
Now traditional lead-acid electric vehicles can still be converted into lithium battery electric vehicles. CSIT electric vehicle lithium battery manufacturer tells you little by little 1. Advantages of lithium battery electric vehicles:
Lithium batteries have long life, light weight, small size, good power performance, and fast charging.
1. Long life
The battery cells of lithium batteries, now good power 5C~10C batteries, can have a cycle life of up to 3,000 times, and still have 70% of the capacity. In other words, the life span is up to 8 years or more. After all, it is really a waste of resources to use the battery cells of electric cars to make electric bicycles. Of course, only CSIT can guarantee the quality for you~
Ordinary lead-acid batteries, that is, they will start to lose capacity after 2 years of use, and the user experience is too poor.
2. Light weight and small size. Because of the high energy density of lithium batteries, the unit volume is 5 times the capacity of lead-acid batteries. Therefore, for the same capacity, lithium batteries are smaller in size and lighter in weight~
3. Good power performance. The discharge characteristics of lithium batteries have the properties of 1C charging and 1~10C discharge. Therefore, lithium batteries can achieve real fast charging and standard power output, giving you a strong power experience.
Because of their own memory, lead-acid batteries will have protection that cannot be deeply discharged. There will be 25% of the power that cannot be released. If it is discharged a little bit, it will seriously affect the life of the battery. Therefore, the capacity utilization rate of lead-acid batteries is 25% lower than that of lithium batteries.
4. Fast charging technology
After the lithium battery pack is enlarged, according to its 1C charging characteristics, it can fully achieve the effect of full charge in 1 hour.
For example, a 20AH lithium battery, with a 7A charger, can be fully charged in 3 hours. A 30AH battery can be fully charged in 4:30 hours. Of course, there are larger chargers, but the cost performance is not high.
The characteristics of lead-acid batteries cannot achieve the effect of fast charging. They can only be charged at a low rate. After 2 years of use, it is common to charge for up to 8 hours. Not to mention the waste of electricity, the charger may be charged all the time, but when discharging, there is no power at all.
Lithium batteries have the characteristics of no activation and no memory.
When using lithium batteries, it should be noted that the battery will enter a dormant state after being placed for a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened. However, lithium batteries are easy to activate. As long as 3-5 normal charge and discharge cycles are performed, the battery can be activated and restored to normal capacity. Due to the characteristics of lithium batteries themselves, it is determined that it has almost no memory effect. Therefore, users do not need special methods and equipment during the activation of new lithium batteries. Lithium batteries do not have a memory effect and can be 100% discharged.
Lithium batteries can achieve 100% charge and 100% discharge. Lead-acid batteries have memory and cannot be discharged to the bottom. They need to occupy 25% of their capacity to protect their lifespan. This is also the problem that lead-acid batteries cannot be deeply discharged. Disadvantages of lithium battery electric vehicles:
Higher price: The cost of lithium batteries is usually higher than that of lead-acid batteries, resulting in relatively high prices for lithium battery electric vehicles.
Safety issues: Lithium batteries may have safety hazards in some cases, such as fire or explosion when overheated, overcharged or physically damaged.
Charging time: Although lithium batteries support fast charging technology, the charging time is still longer than that of traditional fuel vehicles, which may cause inconvenience when they are urgently needed.
Maintenance and protection requirements: Lithium batteries require protection circuits to prevent overcharging and over-discharging, which increases the complexity of maintenance.
High and low temperature use restrictions: The performance of lithium batteries may be affected at extreme temperatures, and special process treatment is required to adapt to high and low temperature environments.
Weight and volume: Although lithium batteries are lighter than lead-acid batteries, the total weight and volume of the battery pack may still be a consideration in some applications, especially in electric vehicles that require long battery life.
Technology maturity: Although lithium battery technology has developed rapidly, it may not be as mature as lead-acid batteries in some applications, especially in high-power electric vehicles.
From the use of electric vehicles modified by myself, the endurance provided by lithium batteries is very strong. When traveling at a speed of 60 kilometers or more, there is still surplus power. At the same time, it can be fully charged in 5 hours, which is very convenient. Considering the previous lead-acid electric vehicles, the battery needs to be replaced in 2 years, and the power starts to decline in 1 year. The lead-acid experience is too bad. Lithium batteries will not lose power characteristics, capacity will not be reduced, and can be used for more than 8 years. You don't need to change the battery when you change the car. It is really cost-effective. On the current congested roads, lithium battery electric vehicles have many advantages. They do not affect time and will not be jammed. They are convenient and fast. Lithium battery electric vehicles will become the first choice for people who understand life.
