Summary:As lithium-ion batteries are gradually applied to various energy storage environments, research on the health of lithium-ion batteries is becoming increasingly important. Electrochemical impedance spectroscopy (EIS) is a practical method for studying batteries, through which multiple health parameters of the battery can be obtained to evaluate the health status of the battery. This article mainly designs an eight-channel battery EIS measurement device for multiple lithium-ion batteries. In the static state of the system, eight lithium-ion batteries are connected to the Neware battery testing system, which can carry out charge and discharge experiments at the same time. After a battery channel is selected, EIS can be measured and the electrochemical impedance spectrum of the battery can be transmitted back to the host computer.
