Method and assembly for determining the output capacity of a battery
First Claim
1. A method for determining the performance of a battery (2) for providing a vehicle power supply system voltage (U) for a vehicle power supply system (4), in particular in a vehicle (6), in which method the vehicle power supply system voltage (U) is recorded, characterized in that the vehicle power supply system voltage (U) and the vehicle power supply system current (I) are monitored for an operating mode which can be predetermined within a time window (Z) which can be predetermined, such that the vehicle power supply system voltage (U) at the end of the time window (Z) exceeds a limit value (G) which can be predetermined, as a function of the vehicle power supply system current (I) which is emitted during that operating mode.

Abstract
A method for determining the performance of a battery for providing a vehicle power supply system voltage for a vehicle power supply system in particular in a vehicle, is provided in order to identify the serviceability of a battery in as simple and reliable a manner as possible, in which method the vehicle power supply system voltage (U) is recorded, in which process the vehicle power supply system voltage (U) and the vehicle power supply system current (I) are monitored for an operating mode which can be predetermined within a time window (Z) which can be predetermined, such that the vehicle power supply system voltage (U) at the end of the time window (Z) exceeds a limit value (G) which can be predetermined, as a function of the vehicle power supply system current (I) which is emitted during that operating mode.
