Definitions

  • the invention relates to a method for operating a motor vehicle with an electrical energy store according to the preamble of patent claim 1.
  • Such energy storage devices typically consist of a plurality of electrochemical cells connected in series to provide the necessary high voltages of up to 650V. Also series connection of cells connected in parallel to increase the capacity are known.
  • the individual electrochemical cells of the energy storage must be monitored to avoid damage from overheating, over-discharge or the like.
  • the individual electrochemical cells are therefore usually assigned sensors for measuring their terminal voltage and / or their cell temperature. In the event of failure of such a sensor, the battery controller no longer has information about the cell in question.
  • the motor vehicle In order to reliably avoid damage in this state, the motor vehicle is usually placed in a short-term emergency condition or equal to completely disabled. Even if an emergency operation is envisaged, it is often not enough to bring the car to a workshop and have the problem remedied. For the driver of the motor vehicle such sensor failures are therefore associated with considerable effort, cost and comfort.
  • a method for monitoring individual cells of a battery is known, for example, from US Pat. No. 6,563,291 B2.
  • the individual cells of the battery monitored by comparing each terminal voltage with voltage limits on over- or undercharging. If a single cell exceeds or falls below such a limit value, an attempt is first made to charge or discharge the cell accordingly. If the fault nevertheless persists after a predetermined time, the battery control will assume a permanent fault and switch off the batteries.
  • a method for monitoring a battery of a hybrid vehicle is known from US Pat. No. 7,173,396 B2, in which, in the event of a sensor failure, an assumed state of charge of the battery is set to a predefined minimum value so that the vehicle remains drivable for a short time. Based on this predetermined value, the state of charge of the battery is further estimated during this emergency operation, wherein when a lower limit for the state of charge, the vehicle is shut down. Also, this method can not ensure that in case of sensor failure, the vehicle can reach a workshop without having to be towed.
  • the present invention is therefore an object of the invention to provide a method according to the preamble of claim 1, which allows a safe and sufficiently long continued operation of the motor vehicle in case of failure of a sensor for an electrochemical cell.
  • the terminal voltage and / or cell temperature of the cell assigned to the sensor is based on the cell voltage and / or the cell temperature of at least one further electrochemical cell Cell of the energy store estimated. Since the individual electrochemical cells of the energy store influence one another, it is thus possible to obtain at least an approximate value for the terminal voltage or the cell temperature of the cell with the failed sensor. As long as this approximation moves within a given range, it is therefore not necessary to shut down the car immediately.
  • the cell temperature of the associated cell is estimated as the average of the cell temperatures of the cell adjacent to that cell. This is possible because there is heat transfer between adjacent cells within the energy store. In this way, the temperature of a cell with a failed temperature sensor can be reliably monitored without much computational or sensory effort.
  • the cell temperatures of the adjacent cells are weighted as a function of their position in the energy store. In this way, a more accurate estimate of the temperature of the cell with failed temperature sensor can be obtained. It is possible, for example, to consider the additional heat loss of marginal cells of the energy store or to compensate for the effects of different heat transfer surfaces between individual cells and a cooling system of the energy store.
  • a correction factor for correcting the mean value of the temperature of the adjacent cells is determined from a cell temperature measured before the temperature sensor has failed or a cell temperature curve measured before the temperature sensor has failed.
  • a particularly good estimate of the cell temperature of the cell with failed temperature sensor is achieved.
  • specific properties of the cell with a failed sensor can be included in the estimation.
  • the mean value of the neighboring cells would be corrected upward if the cell with the sensor already out of order had already shown an increased temperature before the sensor had failed. This can reliably prevent overheating of this cell.
  • the terminal voltage of the associated cell in case of failure of a voltage sensor, as the difference between the total terminal voltage of the energy storage and the Rated terminal voltages of the remaining cells.
  • This is a particularly simple and computationally and sensory not costly method to obtain at least an estimate of the terminal voltage of the cell with failed voltage sensor, which is based on the fact that the individual electrochemical cells of the energy storage are connected in series, so that the total terminal voltage of Energy storage corresponds to the sum of the terminal voltages of all electrochemical cells in the energy storage.
  • a maximum power output of the energy storage is limited to a predetermined value in case of failure of a temperature and / or voltage sensor. This avoids that the cell is overloaded with failed sensor, so that a safe emergency operation is guaranteed with little risk of damage to the energy storage.
  • FIGURE shows a schematic representation of a battery of a motor vehicle for carrying out an embodiment of the method according to the invention.
  • a battery designated as a whole by 10 for supplying power to an electric drive unit of a motor vehicle comprises a plurality of electrochemical cells 12, 14, 16, 18, to each of which a voltage sensor 20, 22, 24, 26 is assigned, by means of which the terminal voltage of the electrochemical cells 12 , 14, 16, 18 is monitored.
  • each electrochemical cell 12, 14, 16, 18 is associated with a temperature sensor 28, 30, 32, 34, with which the cell temperatures are measured.
  • the voltage sensors 20, 22, 24, 26 and the temperature sensors 28, 30, 32, 34 are connected via lines 36, 38 with a battery control unit 40, which registers and stores the measured values of the sensors 20 to 34.
  • a warning signal is generated by the battery control unit 40 and, if appropriate, corresponding countermeasures are taken.
  • the power consumption by the consumers of the motor vehicle can be limited in order to reduce the load on the electrochemical cells 12, 14, 16, 18.
  • an increased cooling of the battery 10 changes in the charging cycle of the electrochemical cells 12, 14, 16, 18, and the like are conceivable.
  • the battery controller 40 attempts to obtain an estimate of the magnitude normally measured by the failed sensor based on the readings of the remaining sensors 20-34.
  • the voltage sensor 22 of the electrochemical cell 14 fails, an estimated value can still be determined for the terminal voltage of the electrochemical cell 14 by adding the terminal voltages of the remaining cells 12, 16, 18 and this value from a total terminal voltage of the battery 10 is subtracted.
  • the value determined in this way is only an approximation, since deviations may occur due to the line resistance of the electrical lines in the battery 10.
  • the battery controller 40 may therefore in this case determine correction factors based on the terminal voltage of the electrochemical cell 14 measured prior to failure of the sensor 22 so as to obtain a more accurate estimate of the terminal voltage of the electrochemical cell 14. Also, a current measurement can be used to improve the estimation.
  • the battery controller 40 may determine an estimate of the cell temperature of the electrochemical cell 14 by averaging the cell temperatures of the electrochemical cells 12 and 16 sensed by the sensors 28 and 32. This is possible because the cells 12, 14, 16 in the Battery 10 are arranged adjacent to each other geometrically, so that a heat transfer takes place between them. Again, a correction is possible on the basis of the cell temperature of the electrochemical cell 14 measured by the sensor 30 before its failure, or on the basis of a temperature profile measured by the sensor 30 in order to obtain more accurate values.
  • the maximum power output of the battery 10 is limited by the battery control unit 40, so that overloads of the individual cells, which can no longer be monitored accurately avoided. In this way it is ensured that the motor vehicle with the battery 10 can still be operated in an emergency operation until a service intervention to repair the defective sensor 22 or 30 is possible.
