Identification method for rechargeable batteries.solar energy storage batteries

　　According to the IEC standard, the identification of nickel cadmium nickel hydrogen batteries consists of five parts

　　1. Battery type KR identification nickel cadmium battery HF represents nickel hydrogen battery HR represents type nickel hydrogen battery

　　2. Battery size information includes the diameter, height, width, and thickness values of circular batteries, separated by slashes in millimeters

　　3. The discharge characteristic symbol L indicates that the appropriate discharge current rate is within 0.5C

　　M represents an appropriate discharge current rate within 0.5-3.5C

　　H represents an appropriate discharge current rate within 3.5-7.0C

　　X indicates that the battery can operate at a high discharge current of 7C-15C

　　4. The symbol for high-temperature batteries is represented by T

　　5. The battery connection piece represents CF, which represents no connection piece. HH, which represents the connection piece used for the battery pull series connection piece. HB, which represents the connection piece used for the battery strip parallel series connection

　　For example, HF18/07/49 represents a square nickel hydrogen battery with a width of 18mm, a thickness of 7mm, and a height of 49mm

　　KRMT33/62HH indicates that the discharge rate of nickel cadmium batteries is between 0.5C-3.5. High temperature series single cell batteries have a diameter of 33mm and a height of 62mm. According to the IEC61960 standard, the identification of secondary lithium batteries is as follows:

　　1. The battery identification consists of 3 letters followed by 5 numbers, cylindrical or 6 square numbers

　　2. The first letter represents the negative electrode material of the battery. I represents lithium ions with built-in batteries. L represents lithium metal electrodes or lithium alloy electrodes

　　3. The second letter represents the positive electrode material of the battery, C based on cobalt electrode, N based on nickel electrode, M based on manganese electrode, V based on vanadium electrode

　　4. The third letter represents the shape of the battery, R represents a cylindrical battery, and L represents a square battery
