1. Charging and discharge ratio: the higher the better. C is a special symbol describing the battery charging current. 1C discharge indicates a current that the battery is from full to empty within 1 hour. If the capacity of the iPhone 6 battery is 1810mAh, the 1C discharge current of the battery is 1.81 amp; if the capacity of each battery used by BYD E6 electric vehicle is 200AH, the discharge current of the battery 1C is 200 amp. If the battery is discharged at a high rate, it usually releases less energy than low -speed discharge
2. The number of charging and discharge cycles: the more the more, the better. 500 times is the common value of lithium ion batteries. The number of charging and discharge of lithium ion batteries made from different materials ranges from 300 to 3,000 times. After 500 cycles, the initial 80%of the battery capacity remained unchanged. There is too much relationship between the number of charging and discharge and the habit of using. Let's take a few examples. 1. The effect of charging and discharge intensity on the number of cycles: Factory description: From 0%to 100%each time, 1C discharge, 0.3C charging, the capacity drops to 80%after 500 times. This is the most serious detection cycle. Not so strict. As shown in the figure below, if the power of each cycle is 25%-75%, 1C discharge, 0.3C charging, the capacity drops to 80%after 2000 times, if the power of each cycle is 50%-100%, 1C discharge, 1C discharge , Charging 0.3, the capacity dropped to 80%after 1800 times. 2. The impact of shallow charge on the service life. Factory reminder: From 0%charging to 100%, 1C discharge, 0.3C charging 500 times, the capacity is attenuated to 80%, which is the most serious detection cycle. It can also be less strict. It can be seen from the below that the power circulation is 25%-75%, 1C discharge, 0.3C charging, and the capacity attenuation to 80%after 2000 times. Each power cycle is 50%-100%, 1C discharge, 0.3 charging, and the capacity is attenuated to more than 80%after 1800. It can be seen from two examples that the smaller the charge and discharge ratio, the more conducive to improving the service life; shallow charge discharge is also conducive to improving the service life
3. Internal resistance: the smaller the better. This parameter changes with the load weight, temperature and other factors. As the battery life is shortened, the internal resistance gradually increases. The smaller the internal resistance, the higher the charging rate. The internal resistance of 18650 ordinary batteries is about 50m, and the internal resistance of the power 18650 battery is about 15m. If you want to know how big the internal resistance is, you need to use special equipment to measure it. Generally speaking, universal watches cannot
