| 摘要 |
The invention relates to an open-loop and/or closed loop control system (1) for a secondary battery (3), having at least two battery cells (2) which can be electrically connected in series with one another, in particular of a motor vehicle which can be powered electrically, having – at least two cell electronics units (4) which are each assigned to at least one battery cell (2), – at least one electronic central processor unit (5) and – at least one communication link (6) via which the electronic central processor unit (5) can be connected in terms of communication technology to the cell electronics units (4), – wherein the electronic central processor unit (5) is configured to detect an electrical actual output voltage which is respectively generated by the secondary battery (3) and to compare said actual output voltage with a predefined electrical setpoint output voltage, to generate at least one control signal as a function of the respective result of the comparison between the electrical actual output voltage and the electrical setpoint output voltage and to transmit the respectively generated control signal to all the cell electronics units (4) via the communication link (6), – wherein each cell electronics unit (4) is configured to detect a respective state of the battery cell (2) assigned thereto, to generate a state parameter assigned to the respectively detected state, to weight, with the respective state parameter, a value, stored in the cell electronics unit (4), of a probability of the battery cell (2), assigned thereto, being switched on and to control the state of the battery cell (2), assigned thereto, as a function of the respective control signal and the value, weighted with the respective state parameter, of the probability of the battery cell (2) being switched on, and – wherein the respective control signal contains at least one information item according to which the values, stored in the cell electronics units (4), of the probability of the respective battery cell (2) being switched on are to be retained, incrementally increased, incrementally reduced or reset to a predefined output value in the next control step. |
