Lithium-ion batteries in ordinary electronic productsThe lifespan is approximately 5 to 20 years, with an average of 8 years. With the current level of technology, lithium-ion. ionic batteries have an electric car lifespan of only about 3 to 5 years.
When the battery capacity of an electric vehicle drops below 80% of its initial capacity, the range of the electric vehicle will be significantly reduced. When the battery capacity drops below 70%, the battery capacity drops below 80% of its initial capacity. The battery needs to be replaced. For many current pure electric vehicles, the battery cost represents around 40% of the total vehicle cost.
Daily maintenance of lithium batteries
1. Just charge them to full capacity for the first time
There is no solution. called batterye nickel-chrome for lithium batteries “Memory effect”, long-term incomplete charging and discharging will not affect the battery capacity. Additionally, lithium batteries usually have a BMS (battery management system) with automatic shutdown when full and protection against over-discharge. In other words, if your lithium battery is fully charged and placed on the charger, it will be charged in vain.
2. Surface Discharge and Surface Charging
If you want to maximize the performance of a lithium-ion battery, you need to "tease" it frequently so that the electrons in the lithium battery are always in a flowing state. Overcharging and discharging will significantly damage the battery, so do not wait until the battery is completely exhausted before charging it.
How long do lithium batteries last?
The lifespan of blithium batteries is only two to three years. Lithium batteries can generally be charged and discharged 300 to 500 times.
It is better to partially discharge the lithium battery than to fully discharge it, and try to avoid frequent full discharges. Once the battery leaves the production line, the clock starts ticking.
Whether you use it or not, the lifespan of lithium batteries is only two to three years. The lifespan of a lithium battery is not calculated in years, but in cycles. The lifespan of a power lithium-ion battery can reach 2,000 cycles. The lifespan of a lithium battery is generally expressed in terms of the number of charges. The specific lifespan depends on usage habits and environment.
Lithium battery life and charging cycle
The lifespan of a lithium batteryium is typically 300 to 500 charge cycles. Assuming that the power provided by a full discharge is 1Q, if the power reduction after each charge cycle is not taken into account, the lithium battery can provide or supplement a total of 300Q to 500Q of power over of its lifespan.
From this we know that if you charge 1/2 each time, you can charge it 600 to 1000 times; if you charge it 1/3 each time, you can charge it 900-1500 times. By analogy, if it is charged randomly, the number of times is uncertain. In short, no matter how you charge it, the total amount of electricity added is 300Q to 500Q, which is constant.
The lifespan of a lithium battery is related to the total charge capacity of the battery and has nothing to do with the number of charges. deepThere is little difference in the impact of a deep load and a surface load on the duration oflife of lithium batteries. In fact, shallow discharge and shallow charge are more beneficial for lithium batteries. Deep discharge and deep charge are only necessary when the product's power module is calibrated for lithium batteries.
In daily life, it usually takes several charging cycles to complete a cycle. Each time a charge cycle is completed, the battery capacity decreases a little. However, this power reduction is very small. High quality batteries retain 80% of their original capacity after being charged several times. Many lithium-ion powered products are still in use after two or three years. Of course, lithium batteries still need to be replaced once their lifespan is reached.
1. Advantages of lithium batteries
1. The lifespan of lead acid batteries is generally 2 to 3 years whene new lithium-ion batteries are used. under the same conditions, the lifespan is generally about 4-5 years. Of course, this is just a theory. Actual lifespan varies depending on people's usage habits.
2. Lithium batteries have no memory effect. Regardless of the battery condition, it can be charged and used at any time. Most batteries need to be charged after the battery is exhausted to avoid memory effects.
3. The volume of lithium battery is about 2/3 of that of lead-acid battery, and the weight is about 1/3 of the weight of lead-acid battery.
2. Advantages of lead acid batteries
1. The price is close to people and there are special channels for recycling old batteries. With the same capacity, the surface price of lithium batteries is about three times that of lithium batteries. Although battery lifelithium battery is theoretically three times longer than that of lead acid batteries, this only seems to compensate for itself. costs more in the initial investment. In fact, an important factor has not been taken into account, namely that the lithium battery is currently broken and there are practically no recycling channels. Even if it is available, it cannot be sold. a lot of money, while lead-acid batteries can recoup at least around 30% of the price of a new battery. Although lead-acid batteries typically only last about a year and a half, lithium batteries still deteriorate after two years of use. I replaced them with new lead acid batteries and they can regain their vitality. However, still-old lead-acid batteries are still a bargain in comparison, at least for ordinary people commuting to and from work.
2. The cruising range can belay to daily use. With the same volume, lithium batteries can run farther, but when the mileage increases, the cost also increases, and the effect is not very obvious to ordinary people who go to or from work, or do their shopping. It is found everywhere in town. The charging socket can be charged at home overnight, which is usually sufficient. If you need it temporarily, you can also get it at work or at a friend's house. for nearby transport. If you are a little further away, you can take a car or drive a 4x4.
3. Easy to replace. There is no management system for lead-acid batteries. If they break down, simply replace them. Lithium batteries are too delicate. You need to protect the card etc. There does not appear to be a unified standard in the market. If it breaks, you usually have to return itreturn to the manufacturer. it's not just for you. It's very useful. If it breaks, you can find accessories anywhere. If it breaks and needs to be sent back to the manufacturer for processing, few people are willing to wait.
4. Safe and reliable. A lot of news about the explosion of electric vehicles is related to lithium batteries, and lead-acid batteries basically eliminate this possibility. This is also an important reason why lead acid batteries can last a long time.
