AI Technical Summary

Technical Problem

In existing technologies, the capacity integration efficiency of multiple batteries in parallel DC power supply systems is low, resulting in excessively long capacity integration time.

Method used

By increasing the output current of multiple batteries, they are prioritized to supply power to the load, thereby enabling simultaneous capacity verification of multiple batteries. Combined with load power and bus current detection, the capacity verification sequence and power control are optimized to ensure the accuracy and stability of the capacity verification process.

Benefits of technology

This reduces the time required for overall capacity verification of the parallel DC power supply system, improves verification efficiency, and ensures the system's power supply stability and the accuracy of the verification results.

Abstract

The application relates to a multi-group storage battery simultaneous capacity checking method and system, and relates to the field of battery capacity checking, which comprises the following steps: step 100: responding to a preset capacity checking signal, a capacity checking number is called; step 101: based on the capacity checking number, a rated current is called; step 102: responding to the rated current, a load current is determined; step 103: according to the load current, a preset parallel module is used to adjust a storage battery current corresponding to the capacity checking number, and a discharge voltage is collected; step 104: based on the discharge voltage, a battery capacity is determined; and step 105: responding to the battery capacity, a storage battery capacity checking report is generated and displayed. The application has the effects of improving the efficiency of storage battery capacity checking and simultaneously checking the capacities of multiple storage batteries.
