Abstract
A method for determining an aging state of at least one cell of a battery. The method includes the step receiving a large amount of operating data relating to the at least one cell of the battery via a memory unit, wherein the operating data can be assigned to a specific point in time. The received operating data is stored in the memory unit with a timestamp which corresponds to the respectively assigned point in time. An aging state of the at least one cell of the battery is calculated using a processor while interdependently taking into account multiple operating data having a common timestamp. The method makes it possible to estimate an aging state using a multidimensional database.
Claims7
A method for determining an aging state of at least one cell of a battery, said method comprising the following steps:
- a. receiving operating data relating to the at least one cell of the battery via a memory unit, wherein the operating data can be assigned to a specific point in time;
- b. storing the received operating data in the memory unit with a timestamp which corresponds to the respectively assigned point in time;
- and
- c. calculating an aging state of the at least one cell of the battery using a processor while interdependently taking into account multiple operating data having a common timestamp.
A measuring apparatus for a battery of a motor vehicle, said measuring apparatus comprising:
- at least one sensor device for acquiring operating data relating to at least one cell of the battery;
- at least one memory unit for storing operating data from the at least one sensor device;
- and
- at least one processor for processing the operating data,
- wherein the measuring apparatus is configured for:
- (i) receiving the operating data relating to the at least one cell of the battery via the memory unit, wherein the operating data can be assigned to a specific point in time;
- (ii) storing the received operating data in the memory unit with a timestamp which corresponds to the respectively assigned point in time;
- and
- (iii) calculating an aging state of the at least one cell of the battery using the processor while interdependently taking into account multiple operating data having a common timestamp.
A computer program comprising:
- a computer program code that can be executed on at least one computer, wherein at least one unit of the computer (i) is disposed in a motor vehicle, and/or (ii) is configured to communicate with a cloud in which at least part of the computer program code is provided,
- wherein the at least one computer is prompted for:
- a. receiving operating data relating to at least one cell of a battery of the motor vehicle via a memory unit, wherein the operating data can be assigned to a specific point in time;
- b. storing the received operating data in the memory unit with a timestamp which corresponds to the respectively assigned point in time;
- and
- c. calculating an aging state of the at least one cell of the battery using a processor while interdependently taking into account multiple operating data having a common timestamp.
