Detection method of German solar storage battery in Substation
The German Sun storage battery adopts the method of substation detection, generally using the verification discharge method. In this method, the German Sun storage battery in operation is withdrawn, and after 24 hours, the resistance is discharged and the discharge current is controlled at 0.1C. The whole voltage and battery voltage are recorded every hour. The battery voltage exceeds the rated terminal voltage within a specified time and is divided into different partitions below the rated terminal voltage. The nucleation method mentioned above takes a long time. If a battery voltage is found to be different in the discharge process, the discharge must be stopped to withdraw from the process, thus affecting the correctness of the nuclear capacity.
After reviewing the domestic and international work experience and consulting scientific data for many years, we found that the internal resistance of the battery can reflect the capacity of the battery. Therefore, by measuring the internal resistance data of the battery, we can analyze whether the battery capacity meets the requirements. The detection method is very simple and does not need to remove the battery. The method is simple, fast, safe and reliable. Therefore, the sizing method of the German solar battery capacity detector can be used instead of the resistance discharge capacity method.
