Method and system for predicting engine-start performance of an electrical energy storage system

A method for predicting a capability of an electrical energy storage system to be able to start a vehicle engine of a specific vehicle make, a specific vehicle model and/or a specific vehicle variant, wherein the electrical energy storage system is a motor vehicle starter battery, and wherein the method comprises the following:

• generating engine-start data, with at least one sensor electrically coupled to the electrical energy storage system, which are characteristic of the electrical energy storage system;
• calculating a predicted start capability of the electrical energy storage system through application of the generated engine-start data to an engine-start prediction algorithm, positioned within an evaluation device, having historical engine start data for different vehicle make and vehicle models and comparison of the generated engine start data to the historical engine start data pursuant to a principle of machine learning;
• and
• outputting a result of the calculation to a display, which result relates to a prediction with respect to the capability of the electrical energy storage system to be able to start a vehicle engine of a specific vehicle make, a specific vehicle model and/or a specific vehicle variant based upon the calculation for an increased accuracy in the prediction,
• wherein the specific vehicle make, the specific vehicle model and/or the specific vehicle variant of a vehicle to be started by the electrical energy storage system is taken into account in order to calculate the generated engine-start data, wherein a temperature or a temperature range of a vehicle engine to be started by the electrical energy storage system is taken into account in order to calculate the generated engine-start data, and wherein the output result of the calculation relates to a prediction with respect to the capability of the electrical energy storage system to be able to start a vehicle engine of a specific vehicle make, a specific vehicle model and/or a specific vehicle variant at different temperatures of the vehicle engine;
• and
• further wherein the capability of the electrical energy storage system to be able to start a vehicle engine of a specific vehicle make, a specific vehicle model and/or a specific vehicle variant is a capability of the electrical energy storage system to be able to cold-start or warm-start a vehicle engine of the vehicle make taken into account in the calculation, the vehicle model taken into account in the calculation and/or the vehicle variant taken into account in the calculation.
