Abstract
A method for predicting an aging state of a battery. A vehicle is also provided that includes at least one battery, the aging state of which is predited using the method and/or the aging behavior of which is improved based on the aging state prediction. A prediction system that is configured to carry out the method is also provided.
Claims13
A method for predicting an aging state of a battery, the method comprising:
- providing data of the battery as a function of various usage profiles of the battery;
- transmitting the data of the battery to a memory device in which data from multiple comparison batteries are stored, processed, and analyzed;
- determining aging state values of the battery at defined times and/or for defined events using a battery reference model;
- forming an aging state pattern of the battery based on the determined aging state values;
- and
- determining a predicted aging state value and/or a predicted aging state pattern of the battery:
- (i) by extrapolating the aging state pattern that is formed, and (ii) by associating the formed aging state pattern with an ascertained aging state pattern from the data of the comparison batteries stored in the memory device, multiple aging state patterns being ascertained from the data stored in the memory device.

A vehicle, comprising:
- a device;
- and
- at least one battery, wherein an aging state of which is predicted and/or an aging behavior of which is improved based on the predicted aging state, wherein the aging state is predicted by the device;
- wherein the device is configured to perform the following:
- providing data of the battery as a function of various usage profiles of the battery;
- transmitting the data of the battery to a memory device in which data from multiple comparison batteries are stored, processed, and analyzed;

- and
- determining a predicted aging state value and/or a predicted aging state pattern of the battery:
- (i) by extrapolating the aging state pattern that is formed, and (ii) by associating the formed aging state pattern with an ascertained aging state pattern from the data of the comparison batteries stored in the memory device, multiple aging state patterns being ascertained from the data stored in the memory device.
