electric carHigh capacity lithium batteryThe service life is 2 years? Many people are very worried about the life of lithium batteries for electric vehicles. How long can a set of lithium batteries for electric vehicles last? Why do some people's high-capacity lithium batteries last for 23 years, and some can even be used? 35 years? In fact, the service life of most lithium batteries is designed to be around 1,000 times (generally 3 yuan lithium battery materials), which is 34 years.

What is the service life of an electric vehicle lithium battery for 2 years? An electric vehicle lithium battery can be used for 2 years? I believe that most consumers have heard that the life of a lithium battery is "1000 times" and 1000 times of battery charging. Beyond this frequency, the rechargeable battery will expire. "End of life", many friends want to increase the charging capacity Every time the battery capacity is completely exhausted, it will be charged. Does this really increase the life of the battery? The answer is no. The life of a high-capacity lithium battery is "1000 times", which does not mean It's not the frequency of charging, it's just the cycle time of a battery charging.

One charging cycle represents the entire process of charging the battery from full to empty, and then from empty to full. This is not equivalent to charging once. For example, a lithium battery only uses half of its energy on the first day. Use electricity, and then fully charge it. If you recharge it the next day Generally, that is, charge half of the time, and charge it twice in total. This can only be counted as one charging cycle, not two. Therefore, it may usually take several charging cycles to complete one cycle. Each charging cycle is completed. , the battery power will drop a little immediately.

However, this reduction in power consumption is very small. High-quality lithium batteries will still retain 80% of their original capacity after being charged several times. Many lithium battery power supply products are still in use after 23 years. Of course, the high-capacity lithium battery of an electric vehicle still needs to be replaced when its life span comes to an end. The so-called 500 times means that the manufacturer has maintained a charging frequency of about 625 times at a stable charge and discharge level, achieving 500 times. Charging cycle. Due to various impacts of actual life, especially the charge and discharge depth during charging is not stable, so "500 charging cycles" can only be used as a reference for lithium battery life.

Ammonium sulfate lithium battery is a type of lithium battery. At present, the charging frequency of ammonium sulfate lithium battery can reach 2,000 times, the cycle life can reach 78 years, and it can be fully charged in 90 minutes on a single charge. It is an ordinary lead-acid battery. It's incomparable, the price is about 2 times that of a lead-acid battery of the same volume.

The cycle life of long-life lead-acid batteries is around 300 times, with a maximum of 500 times, while the lithium iron phosphate battery has a cycle life of more than 2,000 times. With standard charging (5 hours rate), it can be used to 2000 times. Lead-acid batteries of the same quality are "new" Half a year, the old half a year, and "maintenance and maintenance for another half a year", the maximum time is 15 years, and the iron phosphate high-capacity lithium battery is used under the same conditions, the theoretical life will reach 78 years. Comprehensive Considering that the performance price comparison is theoretically more than 4 times that of lead-acid batteries.
