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.

Abstract: A battery health diagnostic system is disclosed, wherein the battery health diagnostic system comprises a battery, the battery configured to be provided in a vehicle having a vehicle state; a sampling device in electrical communication with the battery and configured to acquire battery characteristic data during a vehicle state; a processor in communication with the device, the processer configured to analyze battery characteristic data to produce a battery condition output; and an alert device configured to provide the battery condition output during regular use of a vehicle.

Abstract: A start-stop retrofit kit includes a start-stop module configured to monitor one or more parameters of a vehicle, configured to automatically stop an engine of the vehicle when the vehicle is idling during operation, and configured to automatically start the engine when the vehicle is not idling during operation. The retrofit kit further includes a wire harness configured to couple the start-stop module to a switch disposed between a starter motor and an ignition of the engine of the vehicle, wherein the switch is disposed in parallel with an existing connection between the ignition and the starter motor.
