Design And Practice On The Hardware Of The Multi-Functional Eclectrochemical Power Measurement Workstation

With the abroad opplication of automotive devices and the development of mixed-power car and electric car's techniques, better chemical electrical sources are demanded, therefore, not only measurement of common parameters like capacity and power are requried higher levels than before, but also the new parameters such as the equrvalent circuit refecting the interior principles. Also, the new trend calls for better coherence in battery combination.The purpose of the task is to invent a multi-functional electrochemical workstation in order to statisfy the increasing demand of detecting devices of electrochemistry multi-functional electrochemical is an integrated, digital, electrochemical systematic, analytic device.It combained potentiostat,potentiostatic circuit instrument and AC impedance measurement organticace, which can measure usual dynamic potentio-scan, experiment of dynamic potentio-scan, but also unique measurement of AC impedance measurement, also, this new type electrochemical workstation can carry on complex experiment, sucn as potentio/current scan AC impedance measurement procedural measurment, life-span-circle AC impedance measurement procedural measurement in order to fullfill the goal of track and analysis of parameter in various electrochemical conditions.This graduation thesis indicate the structure, function of the multifunct- ional electrochemical workstation. Apart from that, it also anlagse the basic princple of AC impedance measurement, and introduce the design and experiment of handware of the workstation in terms of basic princple of AC impedance measurement.The study of this graduation thesis includs the aspects as follwos:(1) Design of measuring circuit diagram. It is designed for the measurment of usual dynamic potentio-scan, experiment of dynamic potentio-scan.(2) Desing of interface circuit diagram, can measure usual dynamic...
