  • Publication number: 20230049272
    Abstract: A method for controlling a charging current limiting value for a battery management system. In one example, the method includes determining, for a measured temperature and a prescribed state of charge, reference currents for various time intervals; calculating a corresponding reference time constant for each reference current by using a model for the calculation of a mean value of a charging current based on a continuous current; constituting a diagram for the relationship between the reference time constant and the reference current; determining a predictive time constant by the comparison of a measured value of a charging current with the reference currents; calculating a predictive limiting mean value of the charging current; and calculating a first predictive limiting value ipredS for a short predictive time tpredS, a second predictive limiting value ipredL for a long predictive time tpredL, and a third predictive limiting value ipredP for a continuous predictive time.

  • Publication number: 20230048538
    Abstract: A method for controlling a cell current limiting value for a battery management system. In some examples, the method includes determining quadratic reference currents of a battery cell; calculating a corresponding reference time constant for each reference current using a model for the calculation of a RMS value of a cell current by reference to a continuous current; constituting a diagram for the relationship between the reference time constant and the quadratic reference current; determining a predictive time constant by the comparison of a quadratic measured value of a cell current with the quadratic reference currents; calculating a predictive RMS limiting value of the cell current; calculating a first predictive limiting value for a short predictive time, a second predictive limiting value for a long predictive time, and a third predictive limiting value for a continuous predictive time; and calculating additional RMS limiting value for the cell current.

  • Patent number: 9614796
    Abstract: Solutions are provided for authorizing access to and/or sharing of email attachments. An example method may include, by a computing device, detecting an email message with a file attachment. The email message may identify one or more recipients of the file attachment. The file attachment may be stored in a database table. The database table may include at least one permissions entry controlling access by the one or more recipients to the stored file attachment. The file attachment may be replaced in the email message, with a download link to a location in the database table storing the file attachment. The email message may be delivered with the download link to the one or more recipients.
