摘要： A method for reducing a total loss of charge of battery cells by balancing states of charge includes checking boundary conditions as to whether a vehicle is in the park mode, whether a previous balancing step occurred in the past by at least a defined time period, whether a temperature of a balancing unit lies below an adjustable temperature limit and whether states of charge of all battery cells exceed a minimum state of charge. Additionally, the method includes determining a need for balancing such that a check is made as to whether a maximum difference of all states of charge of all battery cells is greater than an adjustable limit state of charge. Also the method includes, balancing by the balancing units if the first two steps of the method are affirmed. The balancing resistances are connected to respective battery cells for a predetermined time.

摘要： A method for reducing a total charge loss of battery cells by equalizing states of charge includes making an initial check as to whether a temperature of at least one balancing unit lies below a preselectable temperature limit. Thereupon a check takes place as to whether a charging process of the battery cells has completed and the state of charge of the battery cells is >90%. A determination then follows as to whether a maximum state of charge difference between battery cells lies above an adjustable limit (DELTA_SoC).

摘要： A method of use for an electric energy store includes defining a set of states of the electric energy store. The method further includes defining at least one separation surface which separates a first subspace of first states of the electric energy store from at least one second subspace of second states of the electric energy store and detecting at least one influencing factor from the predefinable influencing factors and determining third states of the electric energy store if the electric energy store is used. The method includes estimating at least one state by evaluating at least one influencing factor, checking whether the at least one state is in a predefined subspace for the predefined time and changing use of the electric energy store such that the at least one state is in the predefined subspace at the predefined time based on the check.

摘要： In a method for checking the plausibility of sensor signals, a first sensor element detects at least one first physical quantity and outputs it as a first sensor signal, and a second sensor element detects a second physical quantity correlated with the first physical quantity and outputs it as a second sensor signal. The first sensor element has a first reliability range having an upper limit and/or a lower limit, which range is related to the second physical quantity. The first physical quantity detected by the first sensor element is recognized as plausible if the second physical quantity detected by the second sensor element lies within the corresponding first reliability range of the first sensor element.
