The Research On VRLA Battery Storage Capacity To Test Technology

VRLA battery storage battery capacity test is to understand the normal operation of an important part. It can achieve the life of batteries and battery capacity of real-time monitoring, improve the reliability of the use of batteries, improve the stability of the whole system running. Paper summarizes the characteristics of the battery, comparison of two types of batteries (AGM and GFL), an analysis of homogeneity of batteries and battery capacity, consistency, give VRLA batteries to measure the uniformity of the definition of standard error; the impact of battery power consumption monitoring factors and commonly used detection method.Detect battery parameters on the overall operation of the battery in terms of the importance of its main parameters, monomer battery terminal voltage, in series the total battery voltage, run-time of the inverter voltage, battery resistance, battery capacity, etc. In this paper, the battery voltage inspection form and the internal resistance of detector, respectively, their introduction of the entire hardware design process and software design methods, through the actual operation of the instrument to verify the reliability and feasibility of design, from theoretical analysis of the performance of batteries to provide a reliable data. In order to avoid numerical sampling fluctuations arising Beat show error, the application of digital filtering method inertial sampling inhibit fluctuations in the value of that software to simulate the use of single-chip RC low-pass filter circuit to eliminate jitter and high-order harmonic component of the impact of to achieve numerical stability. Construction of the resistance of the basic model of inspection, monomer battery internal resistance and voltage measurement circuit a combination of inspection and optimization. Injection method to communicate Ways to Optimize proposed measuring the internal resistance of VRLA batteries of the new structure, the use of digital phase-shifting technology to solve the internal resistance measurement circuit voltage and current phase difference measurement of technical problems. Then give the specific implementation methods and circuit solutions implemented through specific programs designed to prove feasibility. Presents a measurement of battery internal resistance to battery life prediction method.
