Do you know how to use a lithium-ion battery correctly? Even if your electric car lithium-ion battery can be used for 2 to 3 days, the soybeans are suggest that you charge every day. Lithium-ion batteries should be charged as soon as possible after using it, so that the battery power is full as possible. The battery regularly performs a deep discharge, which is also conducive to the activation of the battery, which can slightly improve the capacity of the battery.

Here, you will teach you how to extend the life of electric car. First, lithium-ion battery advantages 1, lithium ion battery light weight is small. Lithium-ion battery electric vehicles are currently diversified, in terms of dynamic performance and lead-acid batteries, charged for 6 to 8 hours, depending on the battery capacity of 30 ~ 100 kilometers, with only 1/4 of the lead-acid battery, and currently General lithium-ion battery insurance 2 years (Jiaxiang new energy lithium battery 3 years), lead-acid battery insurance for 1 year.

2, lithium-ion battery has activated characteristics. Lithium-ion batteries are easily activated, as long as 3-5 normal charge and discharge cycles can activate the battery, restore normal capacity. Due to the characteristics of the lithium-ion battery itself, it determines that there is almost no memory effect.

Therefore, the user's new lithium-ion battery is not particularly method and apparatus during activation. 3, lithium-ion battery with memory effect. When the lead-acid battery and nickel battery are charged, it is worried that the battery has a memory effect, while the electric bicycle lithium-ion battery does not have a memory effect, can be safe to charge without worrying about charging electricity before the battery.

4, lithium ion battery cycle life. The lithium-ion battery is charged in 1C magnification, discharges, its cycle life is greater than or equal to 500 times (iron lithium ion battery is more than 2000 times), and the amount of capacitance in the 500th time 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 operating temperature range is wide. The electric bicycle lithium-ion battery can operate in -25 degrees to 55 degrees, and its capacitance can reach 70% of the standard capacity, while the lead-acid battery can only work within 10 degrees to 40 degrees, and cannot be operated at -25 degrees normal work.

6, lithium ion battery is short, green environmental protection. Since the electric bicycle lithium ion battery has a large current charging, the charging time is only 4-5 hours, while the lead-acid battery is 8 to 10 hours. Heavy metal lead, is harmful to the environment, belongs to high-environmental products.

Second, the lithium-ion battery selection points 1, no battery, the battery, no purchase. 2, did not have more than 2 years of market test products. 3, battery without system protection is resolutely not buy.

4, high-priced battery, if it is not produced by the factory, resolutely do not buy. 5. Change the national standard size battery resolutely not buy.

Third, how long does electric vehicle lithium-ion battery life: Can electric car lithium ion batteries for a few years? I believe that most consumers have heard that the life of the lithium-ion battery is 500 times, 500 charge, exceeding this number, the battery is ending, many friends in order to extend the battery life, each time the battery is complete Charging is carried out when it is exhausted, so is it really prolonging the life of the battery? the answer is negative. The life of the lithium-ion battery is 500 times, refers to the number of times of charging, but a cycle of charge and discharge. A charging cycle means that the battery of the battery is used to be empty, and then the process of air is full, this is not equivalent to charge.

For example, a lithium battery only uses half of the electricity in the first day, then charge it slow down. If so, in the second day, it is charged with half, and the total is charged twice, which can only be counted as a charging cycle, not two. Therefore, it is usually possible to complete a cycle several times.

Each time a charging cycle is completed, the battery capacity will be reduced. However, this electricity is very small, and the high-quality battery will still retain 80% of the original capacity, and many lithium-electric power products are still useful after two or three years. Of course, the lithium battery life is still to be replaced.

The so-called 500 times, means that the manufacturer has achieved more than about 625 times in a constant discharge depth, reaching 500 charging cycles. Due to the various influences of actual life, in particular, the discharge depth at the time of charging is not constant, so 500 charging cycles can only be used as a reference battery life. Misunderstanding that we often have lithium ion battery power and then charge it back or the lithium-ion battery is filled, and it will be aired for 12 hours a mistake.

As everyone knows, if you make the lithium-ion battery overcharge or excessively discharge, it is not possible to extend the lithium-ion battery life of the electric vehicle, which will be shortened. So how do you use a lithium-ion battery correctly? Fourth, the lithium-ion battery uses the method 1, charge each day. Even if your electric car lithium-ion battery can be used for 2 to 3 days, it is recommended that you charge every day.

Because the lithium-ion battery after use is in a shallow cycle, it will be prolonged every day. 2, timely charging. Because the lithium-ion battery will enter the vulcanization process after discharge, if it is charged in time, it can remove unscrupulous vulcanization.

Therefore, the lithium-ion battery will be charged as soon as possible after using it, so that the battery power is full as possible. 3, periodically deep discharge. The battery regularly performs a deep discharge, which is also conducive to the activation of the battery, which can slightly improve the capacity of the battery.

The general method is to periodically discharge the battery. 4, try to use the original charger. Generally, don't replace the charger at will not be grasped.

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. 5, lithium ion battery storage. When the battery is not used for a long time, it should be disconnected from the battery and the entire vehicle.

It is given to the battery for a while to prevent battery self-discharge, or protect the battery. Electric cars use small judges to charge, often not fully charged, battery will have a memory, affecting its continuation mileage, while also losing battery life. When charging, first insert the pool plug, plug the power plug.

Charging, first pull the power plug, then pull the battery plug. Second, start the electric vehicle, prevent high current discharge, reduce manned driving, it is best to promote or help ride when climbing the slope, otherwise the damage to the battery is large. If the vehicle is unused in the open or cold storage, it should be removed, stored in a relatively warm room to prevent the battery.

And when the temperature is too low, try to shorten the use time of electric vehicles and should be charged in time. If you are not prepared to use a battery car in the winter, the battery should not be placed again in the year of use, and should be charged 1 month to the battery every 1 month to ensure the storage capacity of the lead-acid battery while preventing acid spillover damage. Battery.

Maintenance personnel say that maintenance battery will remember to charge, more powerful. Before using half a year, it is best to make a battery maintenance, appropriately supplement the electrolyte of the battery, regulate the specific gravity of the electrolyte, and check the storage conditions, maintain the specific gravity of the battery electrolyte, if necessary, can new charge number. At the same time, clean the wires of the battery and apply special grease to protect it.

This ensures that the electric car is really reliable, extending the life of the battery. In fact, the correct use of electric vehicles lithium-ion batteries is still much more, and Xiaobian is not here. When you purchase an electric car, you will usually use instructions.

For your electric car lithium-ion battery longevity, Xiaobian is reminding you, must be performed according to the correct use of the lithium ion battery of the electric vehicle, do not overcharge or excessive discharge of lithium ion batteries. .
