The three-electric system is the main component of the electric vehicle, and the battery is an important component of the three-electric system, the battery can provide an energy source for the electric vehicle, and the battery used in the current electric vehicle is mainly lead-acid battery and lithium battery, both of which have their own advantages, and the disadvantages are also more prominent.
Scientific research institutions have been researching new battery types, and the research on sodium batteries has been going on for some time, but in 2023, sodium batteries have entered the electric vehicle industry, and many electric vehicle brands have released relevant versions of sodium batteries.
Why are people looking forward to the popularity of sodium batteries?
The reason why sodium batteries have attracted people's attention is because sodium batteries have all the advantages of lead-acid batteries and lithium batteries, and abandon their shortcomings, have the safety and stability of lead-acid batteries, and have the lightness and practicality of lithium batteries, and are better than the advantages of these two batteries.
Sodium batteries have five main advantages, including fast charging, long service life, good low temperature resistance, support for discharge to 0 volts, and low price.
1. Support fast charging
Ordinary lead-acid batteries, the charging time is about 8 hours, although the lithium battery supports fast charging, but it also takes 3~4 hours, but the sodium battery supports faster fast charging, which can be charged to 80% in 10 minutes, which greatly shortens the charging time.
2. Long service life
Generally speaking, lead-acid batteries can only be used for 2~3 years, because there are only 300~400 times of charge and discharge cycles, but sodium batteries are different, supporting 2000~3000 times of charge and discharge cycles, which is 5~10 times the service life of lead-acid batteries, and can be easily used for 10 years.
3. Good low temperature resistance
Whether it is a lead-acid battery or a lithium battery, in a sub-zero environment, the charge and discharge will be affected, especially the lead-acid battery, which has a great impact on the temperature, and the cruising range is significantly shortened in winter. Sodium batteries can support low temperature resistance, even in an environment of -20 degrees, can be used normally.
4. Support discharge to 0 volts
We know that whether it is a lead-acid battery or a lithium battery, in the process of use, it is impossible to completely discharge sufficient power, and a protective voltage is required, otherwise the battery will be damaged, but the sodium battery can be discharged to 0V, without any harm to the battery, so that the sodium battery can be stored and transported without charge, with a better degree of safety, and there is no need to worry about the battery being over-discharged.
5. The price is cheap
Although there are many advantages of lithium batteries, the price is twice as high as lead-acid batteries, so lithium batteries have not been popularized rapidly, and sodium batteries are rich in raw materials, so the manufacturing cost will be lower, so the price is cheaper.
In the past, we only knew that the price of sodium batteries was cheaper than lithium batteries, but recently the price of sodium batteries has also been available, and the price of sodium batteries can be seen on the online platform, which is much cheaper than lithium batteries, but slightly higher than lead-acid batteries.
It can be seen through the online platform that the price of 48V30Ah sodium battery is 1243 yuan, which is slightly higher than that of lead-acid battery.
The price of a certain brand of 48V30Ah lithium battery is 1999 yuan, which is much higher than the price of sodium battery. Therefore, the price of sodium batteries is relatively cheaper and more cost-effective.
Summary:
At present, a number of electric vehicle brands have released sodium battery versions of electric vehicles, and they have been put on sale, and it is believed that sodium batteries will be popularized more quickly in 2024, so that car owners can use sodium batteries that support fast charging, longer service life, are more resistant to low temperatures, and are cheaper, so that the cost of using electric vehicles will be further reduced. So, what do you think about this?
