26650 battery

　　Work experience in charging and discharging 26650 battery for electric vehicles

　　The greater the capacity of the lithium battery for electric vehicles, the greater the electromagnetic energy stored in the lithium battery. Because 26650 battery have the advantages of high energy density, small size, light weight, and long life, lithium-ion batteries currently have an increasing share in the sales market. Incorrect charging and discharging conditions or methods will more easily damage 26650 battery and reduce lithium battery life.

　　The capacity discharge process of electric vehicle lithium battery:

　　1. The voltage of the lithium battery of electric vehicles drops rapidly at the end of the original phase. The longer the charge discharge time, the faster the operating voltage drops.

　　2. The voltage of the lithium battery of electric vehicles enters a slow conversion, which is called the plateau area of the battery. The smaller the number of charge and discharge times, the longer the duration of the plateau area, the higher the working voltage of the platform area, and the slower the working voltage. During the entire application process of 26650 battery, it is hoped that the 26650 battery will work in the platform area as much as possible.

　　3. When the lithium-ion battery is close to being discharged, the working voltage of the lithium-ion charge has just begun to decrease until the charge-discharge cut-off voltage is reached. In addition, the relationship between charge and discharge current and volume curve can also be obtained.

　　The relationship between different discharge currents and capacities of 26650 battery for electric vehicles. The size of lithium charge and discharge current will directly affect the capacity of the battery. The greater the charge and discharge current, the lower the battery charge and discharge current, which means that the greater the charge and discharge current, the shorter the time to reach the stop working voltage. Therefore, when mentioning the battery charge and discharge current (charge and discharge multiple), it should be stated.

　　Work experience in charging and discharging 26650 battery for electric vehicles:

　　1. Battery charging, even if the first charging time is short, should be carried out in accordance with the time and procedures of the lithium-ion usage specifications for battery vehicles.

　　2. When an electric vehicle finds that its power consumption is too low, it should be charged as soon as possible.

　　3. Activation of 26650 battery does not require special methods. 26650 battery will be activated naturally during normal use of electric vehicles. If you insist on saying that it will be fully charged for 12 hours when you use it for the first time, it is actually not scientific.

　　4. The battery must be recharged with a compatible lithium battery charger. First, the charging head matches the battery charging outlet, and then the charging plug is inserted into the voltage outlet. If the charging head is lost or damaged, please contact the relevant agent to purchase it. Lead-acid battery chargers or other chargers can be used for charging.

　　5. Partial discharge of electric vehicle 26650 battery is not suitable for overcharge and discharge, and normal and complete charge and discharge must be prevented. Overcharging and discharging will cause adverse effects on the rechargeable battery, especially large current losses, or continuous power loss will be very harmful to the rechargeable battery.

　　6. Long-term charging and power loss will cause more serious damage and damage to the lithium-ion characteristics, which will lead to explosions and other extreme situations. Therefore, if the rechargeable battery is always plugged in to the charging head, sooner or later it will cause misfortune. Because 26650 battery have a high kinetic energy ratio, the battery must not be overcharged to avoid power loss.

　　Excessive discharge will make it difficult to repair the active material. If it directly enters the fast charging mode (high current), it will damage the rechargeable battery, and adding the useful life will be a hidden danger. Although lithium-ion batteries currently use lithium-ion protection plates, under all normal circumstances, the possibility of power loss is very small, but without more accurate maintenance, there will be safety risks in the following situations. The charging time of 26650 battery should not be too long: Do not think that the longer the charging time of the electric vehicle battery, the more sufficient power it will have. Generally, the best time is to extend the time after the charger changes to the light.
