Abstract
In this paper presents a power monitoring circuit for battery energy management system using operational amplifiers. The proposed scheme consists of a current sensing circuit with voltage output and an analog multiplier. The voltage output of current sensing circuit is directly proportional to load current. The multiplying result of the load current in the form of voltage signal and the load voltage becomes the load power in term of output voltage of analog multiplier. The configuration of the proposed power monitoring circuit is simple and economically attractive. Simulation and experimental results confirming the performance of the proposed circuit are agreed with the expected values. ©ICROS.
