This thesis introduces a low cost and high precision temperature cycle measurement system with adoption of PT100 as temperature sensor, with single chip computer as the core. The method of sub-three-wire connection is proposed for engineering practice, then, can eliminate the effects of lead wire resistance and simplify the external cable connection. We discuss and research circuit component selection, circuit design, improving system reliability, and a software method of piecewise linearization process is adopted, thus we ensure exact and reliable measure and the system characteristic of low cost and high precision.

A system of miniaturized lithium battery electrochemical impedance spectroscopy (EIS) measurement is designed with high precision impedance converter chip AD5933 as its core. The measurement range of the system is from 0.010Hz to 100 KHz. Meanwhile, by using a high-level programming language of C#, an interface is developed which can real-time graphic display of EIS information. Through measurement and analysis of two types of impedance, the results show that detection precision of the system is less than 3.5%. Finally, amplitude-frequency response curves and Nyquist plots of HL-18650 M lithium battery at different state of charge (SOC) levels are measured. Compared with lithium battery EIS measurement system by traditional division, this system has the outstanding advantages of small size, high level of integration, low cost, simple operation and high precision. It is helpful to the mass production and application of lithium battery EIS measurement system.
