Method for battery testing, particularly in vehicles, involves evaluating terminal voltage by load acting during limited time interval, where terminal voltage is measured and intermediately stored

摘要

The method involves evaluating the terminal voltage by a load acting during a limited time interval, where the terminal voltage is measured and intermediately stored. The battery is loaded by a predominantly-constant power for reducing the surface charge of the battery. A charging state of the battery is issued as a test result. An independent claim is also included for an arrangement for determining the charge state of a battery.
