brief of Charge Coupled devices (CCD) and its working principles

Leave a Comment / General /

Charge Coupled Devices belong to integrated circuits, which are neatly arranged with many capacitors, which can sense light and convert images into digital signals. Through the control of an electric circuit, each small capacitor can transfer its charge to its adjacent capacitor. CCD is widely used in digital photography, astronomy, especially photometry, optical and spectrum […]

A brief of Impedance-based Battery Management System

Leave a Comment / Cell Manufacturing /

Impedance is an important feature of linear two-port networks. As a system with strong nonlinearity and time-variation, the impedance of the battery needs to be obtained under conditions satisfying causality, stability, and linearity, otherwise, the obtained impedance is difficult to resolve or loses physical significance. Therefore, it is common to apply unbiased weak disturbances (such
