DEVICE FOR AUTOMATIC MONITORING AND EQUALIZATION OF CHARGING DEGREE OF PARALLEL-SERIES CONNECTION OF ACCUMULATORS OF UNIT Russian patent published in 2019 - IPC H01M10/48 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in devices intended for monitoring and levelling of charge parallel-series-connected accumulators, for example, in vehicle unit. Device comprises a power supply in the form of a unit of parallel-series-connected n accumulators, system of battery consumption and charging mode under operation conditions, accumulator switching unit with pairing keys to electric parameters measurement buses, note here that control windings of switches with low internal resistance are connected by their outputs to corresponding outputs of switching control unit. Sensor switching unit comprises temperature sensor switches forming odd and even rows via serial connection. All temperature sensors measuring temperature of accumulators of odd and even rows of accumulator batteries are connected to temperature busbars of accumulators. Displays of temperature distribution of odd and even rows, which are connected in parallel to accumulator batteries, display temperature-related accumulators. Unit for measuring electrical parameters of the accumulator battery by means of a microcontroller, overcharge and undercharge compensation units as per the control signal from the microcontroller is connected to the process of balancing the accumulator battery charge degree.

EFFECT: high reliability and longer service life of the unit of parallel-series-connected batteries.
