DEVICE OF ACCUMULATOR BATTERY CONTROL Russian patent published in 2014 - IPC G01R27/02 

FIELD: measurement equipment.

SUBSTANCE: device of accumulator battery control comprises an accumulator battery, a DC voltage converter, made in accordance with a self-contained generator circuit with a transformer feedback, a current source, a doubled transistor optron, an operational amplifier, two resistors and an additional indicator, besides, the value of resistance R of the first resistor is set as equal to R=E/2J, where E - rated voltage of the accumulator battery, J - value of current generated by the current source.

EFFECT: expansion of functional capabilities of a device by means of control of insulation of accumulator power supply buses to a body, measurement of an output voltage of an accumulator and full galvanic isolation of indicators from power supply buses and accumulator body.
