The battery internal resistance analyzer is a device specifically used to measure the internal resistance of a battery. In the use and research of batteries, the internal resistance of a battery is a key parameter that directly affects the performance, life and safety of the battery. The battery internal resistance analyzer can accurately measure this parameter and provide an important basis for the evaluation and application of the battery.
Its working principle is mainly based on Ohm's law and the AC impedance method. A known AC current signal is applied to the battery, and then the AC voltage response generated at both ends of the battery is measured. According to Ohm's law, resistance is equal to voltage divided by current. By accurately measuring the applied current and the generated voltage, the internal resistance of the battery can be calculated. The AC impedance method uses AC signals of different frequencies to interact with the electrochemical process inside the battery to analyze the impedance characteristics of the battery at different frequencies, so as to more comprehensively understand the composition and changes of the battery internal resistance. This method can distinguish different parts of the battery such as the ohmic internal resistance and polarization internal resistance, and provides a powerful means for in-depth research on the physical and chemical processes inside the battery.
The battery internal resistance analyzer is mainly composed of a signal generator, a measurement circuit, a data processing unit and a display interface. The signal generator is responsible for generating a stable AC current signal, whose frequency and amplitude can be adjusted according to the measurement requirements. The measurement circuit is used to accurately measure the voltage response at both ends of the battery, and requires high precision and high sensitivity to ensure the accuracy of the measurement results. The data processing unit analyzes and calculates the received voltage and current data, obtains the internal resistance value of the battery according to the set algorithm, and further processes and analyzes the data, such as drawing a curve of the change of internal resistance over time or charge and discharge state. The display interface presents the measurement results intuitively to the user, and the user can easily read the battery internal resistance value, view the data curve, and set related parameters through the display interface.
According to different measurement principles and application scenarios, battery internal resistance analyzers are mainly divided into DC discharge method internal resistance analyzers, AC impedance method internal resistance analyzers, and pulse method internal resistance analyzers. The DC discharge method internal resistance analyzer calculates the battery internal resistance by performing a short DC discharge on the battery, measuring the voltage drop and current during the discharge process. This method is simple and intuitive, but the measurement accuracy is relatively low and there is a certain loss to the battery. As mentioned above, the AC impedance method internal resistance analyzer measures the battery internal resistance by applying AC signals of different frequencies, which can provide richer internal information of the battery and has high measurement accuracy, but the equipment is relatively complex and the cost is also high. The pulse method internal resistance analyzer uses short pulse current to excite the battery and measures the voltage change during the pulse to calculate the internal resistance. It combines some advantages of the DC discharge method and the AC impedance method, has the characteristics of fast measurement speed and high accuracy, and is suitable for occasions with high measurement speed requirements.
Battery internal resistance analyzers are widely used in many fields. In battery manufacturers, they are used for quality inspection and control in the battery production process to ensure that the internal resistance of each factory battery meets the standard requirements and improve product quality and consistency. In the field of electric vehicles, real-time monitoring of the internal resistance changes of the battery can timely understand the health status of the battery, predict the remaining life of the battery, provide important data support for the battery management system, and ensure the safe operation and performance optimization of electric vehicles. In the energy storage system, by monitoring and analyzing the internal resistance of the energy storage battery, the performance and reliability of the energy storage system are evaluated, the charging and discharging strategy is reasonably arranged, and the efficiency and service life of the energy storage system are improved. In addition, in the battery research of scientific research institutions and universities, the battery internal resistance analyzer is also an indispensable experimental equipment for studying the performance of new battery materials and battery systems, exploring the influencing factors and changing laws of battery internal resistance, and promoting the innovation and development of battery technology.
With the continuous development of battery technology and the continuous expansion of application fields, the performance requirements for battery internal resistance analyzers are getting higher and higher. In the future, battery internal resistance analyzers will develop in the direction of higher precision, faster measurement, intelligence and multi-function. In terms of accuracy, by improving the measurement circuit and algorithm, the measurement accuracy can be further improved to meet the detection needs of small changes in battery internal resistance. In terms of measurement speed, more efficient measurement technology is developed to achieve fast real-time measurement of battery internal resistance, adapting to the application scenarios of fast detection and online monitoring. In terms of intelligence, artificial intelligence and big data analysis technology are introduced to enable the internal resistance analyzer to automatically analyze the health status of the battery, predict the battery life, and provide intelligent suggestions and decision support based on the measurement results. Multi-function is reflected in the fact that in addition to measuring internal resistance, it can also integrate the measurement functions of other battery parameters, such as battery capacity, voltage, temperature, etc., to provide users with a more comprehensive battery performance evaluation solution.
