The difference between the current and capacity of the lithium battery in normal operation is as follows: 1. The meaning of working current and capacity: the working current is the charging and discharging current in the specific application. Battery capacity is an important consideration for storage of rechargeable batteries, and is a key indicator value of rechargeable batteries, expressed in Mach. According to the analysis of 1ah characteristics, 1ah is equivalent to 100mah, which means that the rechargeable battery is charged and discharged for about 1 hour. The greater the current in a specific application, the shorter the specific charging and discharging time. 2. Capacity and charging current: The volume and current do not necessarily touch, and there are some related large-space rechargeable batteries. If you use a small current to charge, the charging time will be more. Small batteries have more power output. In other words, the current is much larger. We know that the charging head can be used as a DC power supply. Look carefully, each charging head is charged by a wire, and the current is different.

　　3. Battery performance: One of the key performance parameters of the battery is the battery capacity, which is expressed by a certain standard (charge rate and discharge rate, temperature, stop working voltage, etc.), the energy released by the rechargeable battery (JS-150D can be used for charging and discharging The test, that is, the capacity of the rechargeable battery, is generally an ampere clock enterprise (general, the calculation formula for AH battery charging C is CT0IT1DT, which is positive and negative. The battery capacity is divided into specific capacity, basic theoretical capacity and short-circuit capacity according to different standards. .Volume c charge and discharge current (current source) i charge and discharge time (hours) t. charge and discharge time T volume C/charge and discharge current (current source) charge and discharge current (current source) characteristics of lithium batteries: lithium-ion batteries have very Effective power measurement characteristics, in the state of charge and discharge, as the power increases, the battery voltage slowly decreases, and there is a large linear slope. This shows us a similar power measurement method. Take the battery voltage method, It seems that accurately measuring the ratio of length to diameter of the river in the water tank can estimate the remaining water flow. But in fact, the working voltage of lithium ion is much more complicated than the static water level in the tank. Using the working voltage to estimate the remaining capacity of the rechargeable battery, there are many asymmetry phenomena ：Under the same remaining capacity condition of the same rechargeable battery, the working voltage changes with the size of the charge and discharge current. The higher the charge and discharge current, the lower the working voltage. Different types of metal electrodes, charging and discharging service platforms for lithium batteries are very different The charging and discharging platforms of cobalt and lithium manganese are completely different. First of all, this leads to fluctuations in the working voltage of the rechargeable battery and the difference in the working voltage, which makes the volume display information of the rechargeable battery unstable. When the mobile phone uses the working voltage to measure the battery power , It is impossible to maintain a low-current standby state. The basis of the temporary loss of large currents such as power board switching and cell phone ringing discharge is the rapid decrease of battery voltage.
