METHOD AND DEVICE FOR CHARGE AND DISCHARGE CONTROL OF ENERGY ACCUMULATION DEVICE Russian patent published in 2010 - IPC H02J7/04 

FIELD: electricity.

SUBSTANCE: when the ignition off command (IGOFF(1)) is determined at the moment t1, a CCU addresses to a predicted battery temperature pattern and receives the predicted battery temperature (#Tb(1)) corresponding to an ambient temperature (Tout) at the moment t1. When the ignition on command (IGON(1)) is determined at the moment t2, the CCU receives an actual battery temperature (Tb(1)) at the moment t2 and calculates the predicted temperature (#Tb-NEW(1)) after the first ignition on command (IGON(1)) is corrected according to the predicted battery temperature (#Tb(1)) and the actual temperature (Tb(1)). Besides the CCU updates the values corresponding to the ambient temperature (Tout) at the moment t1 by the predicted temperature (#Tb-NEW(1)) being corrected in the predicted battery temperature pattern.

EFFECT: higher reliability of vehicle ignition.
