The battery is a consumable part of the electric vehicle. After a period of use, the cruising range of the electric vehicle will be shortened. At this time, the owner needs to replace the battery to increase the battery life of the electric vehicle. When replacing the battery of the electric vehicle, choose a lithium battery. Good or lead acid battery? Many people can't make up their minds. The following car repair master will tell you the real answer with data.
If you want to know whether to choose a lithium battery or a lead-acid battery when replacing the battery of an electric vehicle, you can compare the performance of the two, including the price, portability, service life, safety and charging speed of the battery. , Let's compare the parameters of the two batteries to see whether it is better to choose a lithium battery or a lead-acid battery.
Price comparison of lithium battery and lead-acid battery
First of all, let's take a look at the prices of lithium batteries and lead-acid batteries. Because the manufacturing process of lead-acid batteries is relatively simple and the cost of materials used is relatively low, the cost of lead-acid batteries is much lower. Recyclable value, when replacing lead-acid batteries, you can take the old-for-new method, and the old batteries can be used to offset part of the cost.
Also due to the manufacturing process, the price of lithium batteries is much higher, generally 2 to 5 times that of lead-acid batteries, and lithium batteries have no recyclable value after use.
Therefore, compared with lithium batteries, lead-acid batteries have more advantages in price, and lead-acid batteries are better in terms of price.
Comparison of service life of lithium battery and lead-acid battery
Whether it is a lithium battery or a lead-acid battery, it has a certain service life. The number of cycles of charging and discharging of the battery determines the service life of the battery. The number of cycles of charging and discharging of the lead-acid battery is about 350 times, and it can generally be used for about 1 to 2 years. , The number of cycles of charging and discharging of lithium batteries is about 3000~5000 times, and generally can be used for 10~15 years. Therefore, the service life of lithium batteries is about 5~10 times that of lead-acid batteries. In terms of service life, lithium batteries should be significantly More advantages than lead-acid batteries.
Performance comparison of lithium battery and lead-acid battery
Due to the manufacturing process, compared with lead-acid batteries, lithium batteries have higher energy density, that is to say, using the same volume of lithium batteries and lead-acid batteries, lithium batteries can store more electricity, so it is said that in the cascade Under the same circumstances, the lithium battery can release more power, and the cruising range of the electric vehicle will be longer, so the performance of the lithium battery is higher than that of the lead-acid battery.
Lithium battery compared to lead-acid battery portability
Next, let's take a look at the portability of lithium batteries and lead-acid batteries. Also due to the manufacturing process, if lithium batteries and lead-acid batteries of the same volume are used, the weight of lithium batteries will be lighter, generally 1/2 of that of lead-acid batteries. 3. Due to the lighter weight, the new national standard electric bicycles that limit the weight often choose to use lithium batteries, which can increase the cruising range of the vehicle without significantly increasing the quality. In terms of portability, lithium batteries are better than lead. Acid batteries are more advantageous.
Lithium battery and lead-acid battery charging speed comparison
During the use of electric vehicles, the battery needs to be charged frequently. Next, let's take a look at which one is faster to charge the lithium battery or the lead-acid battery? Lithium batteries support the function of fast charging, which can be fully charged within one hour, while lead-acid batteries take 6 to 8 hours to charge, so in terms of charging speed, lithium batteries are much faster than lead-acid batteries.
Comparison of the safety of lithium batteries and lead-acid batteries
Safety is an unavoidable topic. Next, let's take a look at which lithium battery or lead-acid battery is safer in use. Also due to the manufacturing process, lead-acid batteries are relatively simple and have high safety. There will be no fire or explosion during use. Lithium batteries are relatively active. If used improperly, it may cause fires and explosions. However, after so many years of lithium batteries, the technology has been greatly improved. As long as it is a big brand of lithium battery, it generally has a BMS battery management system. As long as it is used properly, the lithium battery is very safe.
Summarize:
Through the comparison of the above performance, it can be seen that the price of lead-acid batteries is about 1/3 of that of lithium batteries, but the life of lithium batteries is also about 5-10 times that of lead-acid batteries, so the annual use cost of both Lithium batteries are much lower than lead-acid batteries. In terms of safety, as long as they are used correctly, they are safe and secure. In terms of performance, portability and charging speed, lithium batteries have more advantages. Therefore, when replacing batteries, you only need to choose a big brand. Genuine lithium batteries are more advantageous than lead-acid batteries.
