Analysis of common problems and solutions in the use of lithium-ion power lithium-ion batteries

1). If the battery is found to have abnormal mechanical characteristics such as swelling, broken casing, melting and deformation of the casing, and distortion of the casing before installation and during use, stop using the battery and store it separately; 2). If before installation and use During the process, abnormal phenomena such as loosening, cracks, broken insulation, and burn marks were found in the poles, main circuit wires and connectors of the battery. Stop use, find the reason for the decomposition and repair it; 3). If a lithium battery is found before installation The polarity of the positive and negative poles does not match the polarity identification, please stop using the battery and contact the after-sales service department to replace the battery or obtain other solutions; 4). If the actual power lithium battery is found before installation and during use If the voltage is lower than 2.00V, stop using the battery, and then use a 3.65V0.02C equalization charger to charge the battery. During the whole process, pay attention to observe the battery's voltage change, temperature change, etc., and wait for the battery to charge the voltage in a normal state Reach between 3.60～3.65V and the charging current is less than 0.01C to stop charging, and then leave the battery open for more than 48 hours at room temperature. The open circuit voltage of the battery should be above 3.33V, and the temperature is basically the same as the ambient temperature. If any one of the open circuit voltage and temperature does not meet the conditions, it is considered that the battery is abnormal, please contact the after-sales service department for support information; Statement: Some pictures and content of the articles published on this site are from the Internet, if there is any infringement, please contact to delete it.
