Battery group using detection method in Substation

Battery group using detection method in the substation, the general check and discharge. This method is to run the battery out of operation, standing for 24 hours after the discharge of the battery group with resistance, discharge current control in 0.1C. Each hour records the whole set voltage and the single battery voltage. Within the specified time, the storage battery voltage is qualified above the rated terminal voltage, and the rated voltage is the rated cell under the rated terminal voltage. The time of the above method is long. In the course of the discharge, if a battery voltage difference is found, the discharge should be stopped and the correctness of the nuclear capacity will be affected.
After summing up many years' work experience and referring to the scientific and technical data at home and abroad, we find that the internal resistance of the battery reflects the capacity of the storage battery. Therefore, by measuring the internal resistance data of the battery, it is analyzed whether the battery capacity meets the requirements, and the detection method is simple, and the battery does not need to be out of operation. This method has the characteristics of simple and quick, safe and reliable, so we can use the battery capacity tester of nuclear capacity method to replace the resistance discharge nuclear volume method.
