　　How much impact does fast charging have on 18650 battery rechargeable?

　　How much impact does fast charging have on 18650 battery rechargeable? Practical theory proves that fast charging is the most destructive to 18650 battery rechargeable. The fast charging function is harmful to the battery of the mobile phone. In fact, whether it is fast charging or slow charging, it will damage the battery life. The main reason why fast charging affects the battery life of mobile phones is that it increases the power. Charging will bring more heat than slow charging, and high temperature will accelerate battery aging.

　　Fast-charging 18650 battery rechargeable refer to batteries that are charged in a short time. Generally, the battery is fully charged within 6 minutes, and the battery capacity reaches more than 95% of the rated capacity. Time is life, and fast-charging batteries shorten charging time, improve efficiency, and reach international advanced levels.

　　Requirements for fast charging 18650 battery rechargeable

　　●According to the structural characteristics of fast-charging 18650 battery rechargeable, the maximum charge termination voltage should be 4.2V. Overcharging is not allowed, otherwise too much lithium ions from the positive electrode will be taken away and the battery will be scrapped.

　　●18650 battery rechargeable have high charging and discharging requirements and can be charged using dedicated constant current and constant voltage chargers. Usually, constant current charging reaches 4.2V/section and then it switches to constant voltage charging. When the constant voltage charging current drops to less than 100mA, charging should be stopped.

　　●Charging current (mA) = 0.1~1.5 times battery capacity (for example, for a 2000mAh battery, the charging current can be controlled between 200~4000mA). The conventional charging current can be selected to be around 0.5 times the battery capacity, and the charging time is about 2 to 3 hours.

　　How much impact does fast charging have on 18650 battery rechargeable?

　　Whether 18650 battery rechargeable can be charged quickly depends on the experimental data of lithium battery manufacturers. Not all 18650 battery rechargeable can be charged quickly. Otherwise, the life of the lithium battery will be greatly reduced, and there will be dangers such as fire and explosion. Therefore, each manufacturer will configure slow charging ports and fast charging ports according to the characteristics of 18650 battery rechargeable, and the BMS system will uniformly manage the charging process. As long as charging is carried out in accordance with the manufacturer's requirements, it is safe.

　　18650 battery rechargeable and lead batteries are the same principle. The working principle of fast charging is: first increase the voltage, and second, increase the current current. Just like this, fast charging also uses this principle, so a large amount of current will cause the battery plate to react at an excessive speed. This reaction can generate a large amount of heat due to internal resistance and exceed limiting temperature values, thereby damaging or prematurely aging the battery.

　　18650 battery rechargeable have no charge memory. The so-called nominal number of charges is 500, which means that it can be charged from 0 to 100% 500 times.

　　Strictly speaking, any fast charging of a battery will damage the battery. But if the lithium battery density, materials, temperature and battery management system of electric vehicles are designed very reasonably, then this damage will be within a reasonable range, and it can be simply understood that the battery will not be harmed.

　　The charging speed of electric vehicle 18650 battery rechargeable depends on the three indicators of battery density, temperature and material. In other words, one of these three indicators is not up to standard, and fast charging is very harmful to the battery. In addition, the role of the battery management system is also very important. It controls the input current and voltage during battery charging to minimize damage to the lithium battery.
