How long do lithium batteries in electric vehicles last?

Lithium battery: The average lifespan is about 4 years, about a year longer than lead-acid batteries. It can be charged and discharged more than 500 times. Of course, if you buy a relatively poor battery, or if you don't pay attention to its maintenance during daily use, it will only go more than 10 kilometers after more than a year of use.

Lead-acid battery: Generally, it can be charged and discharged in 400 times, and its lifespan is about three years.

Compared with lithium batteries, the disadvantages of lead-acid batteries are obvious, that is, they are bulky, inconvenient to use, have limited battery capacity, and have a relatively short lifespan.

However, lead-acid batteries also have the irreplaceable advantage of lithium batteries, which is why lead-acid batteries remain widely used.

Advantages oflead-acid batteries:

1. Good safety performance. Lead-acid batteries are easy to maintain. You can knock them over, fix them a little and continue to use them.

2. Cheap price. The price of lead-acid batteries is about 1/3 that of lithium-ion batteries, which shows how low the price is.

3. Recyclable reverse repair. Lead acid batteries are highly recyclable. Once worn out, you can go to an electric car store to exchange them for new ones. You can exchange them for a new set of batteries by paying the price difference, thus minimizing losses. a great advantage for users. Battery lead can also be recycled and reused, reducing environmental pollution.

Based on product quality, after-sales service and price, we recommend several brands of relatively good lead-acid batterieses: Changxin Battery, Shinhwa Battery and Mantingfang Battery.

Which is better, a lithium battery or a lead acid battery?

Lithium batteries and lead-acid batteries are common types of batteries. They have their own pros and cons, but which one is more sustainable?

First of all, the advantages of lithium batteries are that they are small in size, light in weight, durable, can provide higher energy density, can provide longer life, and can charge faster than lead acid. batteries are much faster.

In addition, lithium batteries discharge more quickly than lead-acid batteries and can provide more power.

However, lead-acid batteries also have their own advantages.

They are much cheaper than lithium batteries and charge more slowly than lithium batteriesm, thus providing a longer lifespan.

In addition, lead-acid batteries discharge more slowly than lithium batteries and can provide more power.

In general, lithium batteries are more durable than lead acid batteries.

Lithium batteries are small, lightweight and durable, can provide higher energy density, can provide longer life, and can be charged much faster than lead-acid batteries.

In addition, lithium batteries discharge more quickly than lead-acid batteries and can provide more power.

Therefore, lithium batteries are more durable.

However, lead-acid batteries also have their own advantages. They are much cheaper than lithium batteries and charge faster than lithium batteries. The batteries are slower and can provide a longer lifespan.long.

In addition, lead-acid batteries discharge more slowly than lithium batteries and can provide more power.

Therefore, lead-acid batteries are also a good choice.

In short, lithium batteries and lead-acid batteries have their own advantages and disadvantages, but in terms of durability, lithium batteries are better.

Its small size, light weight and durability can provide higher energy density, longer life and much faster charging than lead-acid batteries.

In addition, lithium batteries discharge more quickly than lead-acid batteries and can provide more power.

Therefore, lithium batteries are more durable.

However, the final choice should be decided based on the actual situation, because each battery has its own advantages and disadvantages.

Lithium batteries for vehiclesDo electric batteries have a longer lifespan than storage batteries?

Lead-acid batteries

“Lead-acid batteries batteries are safe, From the perspective of internal structure, the larger the capacity of a lithium battery, the worse the heat dissipation, which means it is more likely to ignite or spontaneously explode. lead plates, and its capacity is not as good as that of lithium batteries, but its performance is relatively stable, less likely to spontaneously ignite or explode, so it will be safer. »

Lead acid battery. (VRLA) is a battery whose electrodes consist mainly of lead and its oxides, and the electrolyte is a solution of sulfuric acid. In the discharged state of a lead-acid battery, the main component of the positive electrode is lead dioxide and the main component of the negative electrode is lead.lead ; in the charged state, the main components of the positive and negative electrodes are both lead; sulfate.

Long time.

The lifespan of most lithium batteries is designed to be approximately 1,000 times longer (ordinary ternary lithium battery materials), or 3 to 4 years. The lifespan of lead-acid batteries is about 300 times, and the maximum is 500 times.

A charge cycle means that all of the battery's energy is used from full to empty, then charged from empty to full. This is not the same as a single charge. For example, a lithium battery only consumes half its power the first day and then recharges slowly.

If it's still the same the next day, i.e. charging half the time and charging twice in total, this can only be counted as one charging cycle, and no two. multiple charge cycles to complete one cycle. Every time a cThe charging cycle is finished, the battery capacity decreases a little. ?

Detailed information:

Notes:

1 . The lifespan of electric vehicle batteries is very long. Lithium iron phosphate batteries should be charged and discharged frequently and should not be stored for long periods of time. When driving an electric vehicle, you should get into the habit of charging it after 80% of the battery is used. Regardless of the distance traveled, it is best to recharge the battery and not wait until it is exhausted to recharge it.

2. When charging the electric vehicle battery in the vehicle, the electric door lock must be closed. Do not charge the battery reversely. Try to fully charge the battery at the same time.

3. When the electric vehicle battery is not used for a long timeth period, it should be charged once a month. Store the battery once it is fully charged. Do not store it in a power loss state.

4. When using the battery charger, use the corresponding charger. Since the battery raw materials and production processes of lithium batteries are different, the technical requirements of chargers are also different, so special chargers must be used for charging.
