| titleOfInvention | Auxiliary accumulator system and method for evaluation of mechanical stress of active material of auxiliary accumulator |
| abstract | FIELD: electrical engineering. n SUBSTANCE: invention relates to electrical engineering, namely to evaluation of mechanical stress of active material of accumulator, and can be used for estimation of auxiliary accumulator charge state. Auxiliary accumulator system includes electronic control module (ECU), which evaluates surface mechanical stress formed in active composite material of negative electrode at inclusion or removal of lithium in negative electrode of accumulator unit, wherein the ECU calculates the estimated value of the surface mechanical stress from the difference obtained by subtracting the reference amount of lithium from the amount of lithium contained in the active material of the negative electrode, using a linear relationship between the auxiliary storage battery (SOC) charge difference and the surface mechanical stress. ECU specifies surface mechanical stress equal to mechanical stress at fluidity repartition, when the absolute value of the estimated value exceeds the absolute value of the mechanical stress in the course of fluidity (mechanical stress during compression or mechanical stress at tension) of the active material, and uses the estimated value as the surface mechanical stress, when the absolute value of the estimated value is less than the absolute value of mechanical stress in the course of fluidity. Disclosed method enables to estimate state of charge and full charging capacity of storage battery considering surface mechanical stress of composite material, which can include other materials provided that the material exhibits significant hysteresis only in part of the SOC region. n EFFECT: technical result of the invention is improvement of accuracy of evaluation of mechanical stress formed in active material of auxiliary accumulator. n 9 cl, 19 dwg |
