US 2025/0187492 A1 · METHOD AND SYSTEM FOR PREDICTING ENGINE-START PERFORMANCE OF AN ELECTRICAL ENERGY STORAGE SYSTEM

Abstract

The invention relates to a method for predicting an engine-start performance of an electrical energy storage system, in particular a motor vehicle starter battery. The method comprises the following method steps: generating engine-start data which are characteristic of the electrical energy storage system; evaluating the generated engine-start data; and outputting a result of the evaluation, which result relates to a prediction with respect to the engine-start performance of the electrical energy storage system. According to the invention, provision is made in particular for a vehicle make, a vehicle model and/or a vehicle variant of a vehicle to be started by the electrical energy storage system to be taken into account in order to evaluate the generated engine-start data.

Dependent claims

A method for predicting a capability of a battery to be able to start a vehicle engine of a vehicle, the method comprising:

generating engine-start data characteristic of the battery with a sensor coupled to the battery;
calculating, using an evaluation device, a predicted start capability of the battery through application of the generated engine-start data and historical engine start data to an engine-start prediction algorithm housed in the evaluation device;
and
providing a result of the calculation, with the result being an increased accuracy in the prediction of the capability of the battery to be able to start the vehicle engine of a specific vehicle make, a specific vehicle model and/or a specific vehicle variant based at one or more temperatures of the vehicle engine.
