| Abstract: | In this paper,a battery internal resistance measurement system based on STM32 microprocessor was designed.The internal resistance of the battery was measured by ac impedance method.Aiming at the characteristics of weak measurement signal and easy to be submerged in noise,correlation detection technology was applied to detect useful information.The experimental data show that the system can measure the internal resistance of the battery online,quickly and accurately. |
