AUTOMATIC MONITORING OF BATTERY PACK WITH TEMPERATURE CONTROL Russian patent published in 2019 - IPC H01M10/48 H02J7/00 

FIELD: physics.

SUBSTANCE: invention relates to devices intended for monitoring and correction of accumulator parameters, including temperature control of each accumulator in the unit. Device comprises power supply in form of in-series connected accumulators of unit 1 AB, system of consumption and charging mode 2 (SDZ) of accumulators, group of single-position normally open electromechanical keys 3 with low internal resistance, common electric buses 4 (a) and 5 (b). Switching unit 6 switches buses 4 (a) and 5 (b) from the automatic control system 7 unit to the final alignment system unit 8 and performs charging of the problem battery from the backup accumulator for a certain period of time. Microcontroller 9 (MC) with the data bus is connected to digital indicator 10 (CI1) of sequence numbers of problem accumulators when measuring their electrical values, and control bus to input of dual demultiplexer 11 (DMS). Unit of measuring thermoresistors 12 (IT) with high internal resistance, commutation buses 13 (c) and 14 (d) and compensating unit 15 form measuring bridge, which measures temperature difference of two adjacent even and odd working accumulators of 1 AB unit by voltage difference between switching buses 13 (c) and 14 (d). Diode unit 16 consists of two diode connected diode and transformer 17 (T) with two primary and one secondary windings. Operational amplifier 18 (OA) with non-inverting input, instrumental amplifier 19 (AC), accurate temperature meter 20 (TIT) of near-to-ground working accumulator An unit 1 AB. Digital indicator 21 (CI2) of serial numbers of temperature-sensitive accumulators of unit 1 AB, information bus connected to microcontroller 9 (MC). Display 22 displays temperature field across all working accumulators 1 of SB unit, data bus is also connected to microcontroller 9 (MC).

EFFECT: use of the proposed invention in devices intended for monitoring and correction of parameters of accumulators due to an extended range of diagnostic features, will significantly improve reliability and increase service life of accumulators in the battery.
