Description
Technical field
The present invention relates to a kind of substituting battery unit for battery system, it has circuit, described circuit is configured to, identify the balance parameters of equalization methods of battery system and the equilibrium by using this balance parameters to implement the autonomy of the charged state of described substituting battery unit, described equalization methods is used for the equalizing charge between the secondary battery unit of battery system.
Background technology
Be made up of a large amount of secondary battery unit for the batteries of electric motor car and/or motor vehicle driven by mixed power or battery system.Exceed the life-span of batteries, these secondary battery units different amplitudes ground is aging, thus the life-span of last the fastest aging secondary battery unit determination batteries.Following situation can be there is equally, i.e. one or more secondary battery unit faults of batteries.The obligation after sale of 15 years of secondary battery unit is a problem for the current manufacturer of secondary battery unit, because can not storing on the very long time interval according to the aging of calendar of standing based on it of secondary battery unit.The regenerative ratio of secondary battery unit is difficult because after 15 years based on technological progress not only original raw material of manufacturing of this secondary battery unit and also corresponding manufacturing installation itself all unavailable.
If such as cause the malfunctioning of one of the secondary battery unit installed in this batteries in the debugging first of batteries after 10 years, so can be based on: the original secondary battery unit for this batteries no longer can be used: so must install the batteries more of new generation with other features, this causes problem naturally.Such as can suspect, secondary battery unit more of new generation has higher performance data compared to the secondary battery unit needing to be replaced in its energy and its power density.The secondary battery unit of the energy higher based on this or this renewal of power density also has less structural shape mostly.If attempt now such secondary battery unit more of new generation to be installed in older batteries, so typically also such as produce following difference compared to older secondary battery unit:
That upgrade and less secondary battery unit is due to its link (namely its accumulator terminal) no longer matched batteries group.Because secondary battery unit in the beginning in its life-span and electric capacity compared to nominal electric capacity also not due to aging decline, so secondary battery unit still has higher electric capacity when identical nominal electric capacity.In addition described secondary battery unit has less internal resistance and less self discharge.
In addition caused the electric property of new-type secondary battery unit by these differences, described electric property causes problem in the trial of batteries same secondary battery unit being applied to an older generation.The secondary battery unit such as upgraded is in operation based on its less self discharge and higher electric capacity and weaker discharges.The secondary battery unit so upgraded in charging reaches maximum voltage as first in the secondary battery unit of batteries and complete charge process thus, thus older more weak secondary battery unit charges no longer completely.In order to stop this point, this secondary battery unit discharges with its balance policy by the balanced unit of battery management system or the battery system that is wherein provided with new-type secondary battery unit consciously.Based on higher electric capacity, the secondary battery unit of renewal requires the available time for balance of greater part so naturally.This causes again: the time for balance less for the older secondary battery unit of batteries can be used, and the equalization performance of the balanced unit of battery management system or battery system is no longer enough generally, thus the total capacitance of batteries at short notice so degree ground decline, even if make batteries have one or more replacement battery unit also no longer meet the life-span border of 15 years.
