About lithium battery capacity sorting?
About lithium battery capacity sorting? When the battery capacity is divided, the data of each detection point is obtained through computer management, so as to analyze the data such as the size of the battery capacity and internal resistance, and determine the quality level of the battery. This process is the capacity division. During the battery manufacturing process, in…
About lithium battery storage?
About lithium battery storage? Short-term storage of lithium batteries: Lithium batteries should be stored in a dry place with no corrosive gas and a temperature between -20 degrees and 35 degrees to avoid rusting of lithium battery metal parts or battery leakage. Long-term storage of lithium batteries: 1. Lithium batteries should be kept at 50%-60% state of charge if they…

About OCV testing when to check?
About OCV testing when to check? OCV is the open circuit voltage. OCV detection is mainly to measure the battery characteristics by pressing the probes connected to the voltage tester and internal resistance tester on the positive and negative tabs of the pouch battery. OCV test is an important part of battery testing. . After the first charge of the…
About the measurement and detection of OCV?
About the measurement and detection of OCV? Open circuit voltage (OCV) detection On the production line of lithium battery cells, the measurement of open circuit voltage is one of the important inspections for detecting defective products. Because the battery has self-discharge characteristics, the open circuit voltage value will gradually decrease accordingly. If the battery has internal defects, then it will…
About the difference between OCV1 and OCV2?
About the difference between OCV1 and OCV2? OCV1 and OCV2 should be the distinction of open circuit voltage in different states. OCV1 represents the open circuit voltage measured at time t1. OCV2 represents the open circuit voltage measured at time t2, which is generally used to calculate the K value of the lithium battery (the voltage drop per unit time,…
About OCV?
About OCV? OCV is Open circuit voltage = open circuit voltage, which refers to the potential difference between the two poles when the battery is not discharged and the circuit is open. Open Circuit Voltage: Voltage range: 0.01mV~100mV Voltage resolution: 0.01mV [setting of upper and lower limits of test item parameters] Standard test items: open circuit voltage (OCV) Measuring range:…
