The electric vehicle lithium battery is mainly divided into three major categories. The first is three yuan lithium, which is also the most used lithium battery, the second phosphate battery, and the third titanate, wherein the lithium titanate is very low. Few people.

How long is the number of electric vehicle lithium batteries? Do you know how to use a lithium battery correctly? Today, Xiaobian is talking about it. Electric vehicle lithium battery life is designed to be around 1000 times (ordinary three yuan lithium battery), which is 3-4 years. But this does not mean that after 3-4 years, the life of the lithium battery is terminated.

Lithium iron phosphate battery is one of a lithium ion battery. At present, the number of charging of lithium phosphate batteries can reach 10,000 times, and the life of the cyclic service can reach 7-8 years. It can be filled over 40 minutes at a time.

It is generally the general lead-acid battery that is the same capacity lead-acid battery 12- 15. Long life lead-acid battery cycle life is around 300 times, the highest is 500 times, while the lithium phosphate battery, the cycle life reaches more than 2,000 times, standard charging (5 hours), can reach 2000 times. The same quality lead-acid battery is "new half year, old half year, maintenance and maintenance and half year", up to 1 to 1.

5 years, while lithium iron phosphate batteries are used under the same conditions, the theoretical life will reach 7-8 years. Comprehensive consideration, performance price is more than 4 times more of the lead-acid battery than theoretically. Electric car lithium battery life, the problem and lithium battery should be paid attention to in terms of charging, and the more delightful is that it has been developed to extend the life of lithium battery, but this technology is not common, news After exploding, many consumers are also expected, although the life of lithium batteries can be extended, but everyone must use correct use to ensure that lithium batteries will not be scrapped in advance.

Advantages of electric vehicle lithium battery 1. Lithium battery weight Light volume Small lithium battery electric vehicle is currently diversified, in terms of dynamic performance, and lead-acid batteries, charging 6 ~ 8 hours, can run 30 to 45 kilometers depending on battery capacity. The weight is only about 1/5 of the lead-acid battery, and the general lithium battery is currently guaranteed for 2 years, and the lead-acid battery guarantees for 1 year.

2, lithium battery has an activated characteristic lithium battery is easy to activate, as long as it passes through 3-5 normal charge and discharge cycles, the battery can be activated, and normal capacity is restored. Due to the characteristics of the lithium battery itself, it determines that there is almost no memory effect. Therefore, the user's new lithium battery is in the process of activation, it does not require special methods and equipment.

3. 4, lithium battery circulating life long lithium ion battery charges in 1C magnification, discharge, its cycle life is greater than or equal to 500 times, the amount of capacitance is greater than the nominal copper beam 70%. The lead-acid battery is charged at 0.

15c, and the cycle life is less than or equal to 350 times, and the capacitance is less than or equal to 60%. 5, the working temperature range wide electric bicycle lithium-ion battery can operate within -25 degrees to 55 degrees, with capacitance to reach 70% of the standard capacity, and the lead-acid battery can only work within 10 degrees to 40 degrees. Do not work properly when -25 degrees.

6, the charging time of the lithium battery is short, the green environmental protection is due to the characteristics of the electric bicycle lithium-ion battery, so the charging time is only 4-5 hours, while the lead-acid battery takes 8 to 10 hours. Heavy metal lead, is harmful to the environment, belongs to high-environmental products. Electric Vehicle Lithium Battery Precautions 1.

Because the lithium battery after use is in a shallow cycle state, charging will extend the life of the electric vehicle lithium battery every day. 2, timely charging because the electric vehicle lithium battery will enter the vulcanization process after discharge, if it is charged, it can remove non-severe vulcanization. Therefore, the lithium battery will be charged as soon as possible after using it, so that the battery power is full as possible.

3, regular deep discharge cells Regularly conduct a deep discharge is also conducive to the "activation" battery, which can slightly improve the capacity of lithium batteries. The general method is to periodically discharge the battery. The fully discharged method is to ride the first undervoltage protection under normal load of flat pavement.

After the battery is in the first undervoltage protection, the battery has returned to the non-output of the non-voltage state after a period of time, and the battery capacity will be improved. It should be noted that when the lithium battery is first undervoltage protection, do not use the battery, this time is very damage to the lithium battery. 4, try to use the original charger, each manufacturer's lithium battery charger generally has a personalized demand, do not replace the charger at will not be able to.

In addition, do not remove the speed limit of the controller, remove the speed limit of the controller, although the speed of some cars can be improved, but will reduce the battery life of the battery. The above is the life of electric vehicle lithium battery life and correct usage. The lithium iron battery life theory should be 4-6 years, and the special charger must be used to damage the battery.

The charge and discharge of the lithium iron phosphate battery is 2,000 times.
