摘要： A method for monitoring the conditions of driving systems can be used in particular to control driving systems in hybrid vehicles with particular consideration given to the exhaust emission. The method monitors the conditions of driving systems that comprise an internal combustion engine and an electric motor with an energy source. A first power value for operating the internal combustion engine and a second power value for describing the power that can be provided by the energy source are ascertained, and the first and second power values are compared with each other to monitor the conditions of the driving system. The driving system is controlled dependent on the result of the comparison.

摘要： A method for determining the power that can be provided or absorbed by a battery includes determining a state variable of the battery. A power that can be provided or absorbed by the battery during a specified load period is determined using a table of power values and the state variable of the battery. The state variable of the battery is used as an access parameter for the table. A load of the battery is measured using an operating parameter of the battery. A load period in which the load of the battery is given is measured. The measured load period is compared with a comparison range that contains the specified load period. A correction routine is carried out if the load period lies in the comparison range. A battery system includes a controller for carrying out the method. A motor vehicle includes the battery system.

摘要： A method for balancing states of charge of battery cells of a battery includes determining the individual cell capacities of the cells. A k-th cell having the smallest cell capacity, the individual states of charge, the depth of discharge, a target depth of discharge, and a target state of charge are determined. The deviation of the state of charge of a cell from the target state of charge (ΔSOCtarget,n) and the minimum deviation of the state of charge of a cell from the target state of charge (ΔSOCmin) are determined. At least one of the cells, to which ΔSOCtarget,n−ΔSOCmin>X applies, where X≧0, is discharged. If ΔSOCtarget,n−ΔSOCmin≦X applies to all cells, the method ends. If this condition does not apply to all cells, the individual states of charge are determined again and the method is repeated.

摘要： A method for initializing and operating a battery management system is disclosed. The method comprises the following steps. First, start the battery management system. Next, read battery variables which are stored in a nonvolatile memory of the battery and comprise the last state of charge of the battery. Then measure the open-circuit voltage of the battery. Next, determine an instantaneous state of charge value on the basis of the measured open-circuit voltage. Then determine an estimated value of the state of charge of the battery as a function of both the stored last state of charge of the battery and the instantaneous state of charge value. Then initialize the state of charge in the battery management system using the determined estimated value of the state of charge. Finally, operate the battery management system with the initialized values.
