Monitor Of Charging And Discharging Storage Battery In Service

This paper introduces a new type instrument that can monitor charging and discharging industrial storage batteries of various capacities on line. In the measurement of forward channel Hall effect is applied to form current sensor, so the volume of instrument is decreased. Since this system adopts low-power consumption design of single-chip microcomputer, it has some features, such as: simple structure and high degree of intellect. Especial technique of anti-interference is applied in this system to resist strong electric-magnetic interference. At last, the paper gives hardware structural diagram of the digital measuring system and idea of software program.
