AUTOMATIC CONTROL METHOD FOR ACCUMULATOR BATTERY CONSISTING OF N GALVANIC COUPLED ACCUMULATOR CELLS AND DEVICE FOR AUTOMATIC CONTROL Russian patent published in 2015 - IPC H01M10/00 

FIELD: electricity.

SUBSTANCE: method lies in the delivery of signals from a microcontroller (MC) to address inputs of the switch, sequential connection of the switch to two adjacent outputs of an accumulator cell (AC) with their voltage control wherein upon connection of the switch an additional floating common bus with a voltage of an adjacent output of the controlled AC and measuring buses are formed, AC voltage difference at the buses is shifted in a sequence in a positive direction, then in a negative one, in regard to the floating common bus using a current generator controlled by voltage. In AB control process a measuring path is calibrated and stabilised by the installation of a reference voltage source (RVS) to a thermostat, and at AB control voltage of even AC is inverted. The device for automatic control comprises a switch, RVS, MC, a decoder with a galvanic isolation unit, additional common and measuring buses connected to two devices for signal level shifting on the basis of RVS and a voltage-controlled current source using a high-voltage transistor. At that keys for the through calibration of the path are introduced to the device and RVS is installed in the thermostat.

EFFECT: increased accuracy and reliability of control.
