Method for testing battery, such as lithium-ion batteries for electronic devices, such as mobile phones or laptops, and in automotive sector, involves measuring parameter of battery at time period and heating of battery

摘要

The method involves measuring a parameter of a battery (6) at a time period, heating of the battery, and measuring the parameter of the battery at another time period. The difference between the both parameters are determined, and are compared with a predefined threshold value. The defect of the battery is automatically recognized, if the difference exceeds the threshold value. The battery is formed as a lithium-ion cell or a high-voltage battery pack, particularly multiple lithium-ion cells. An independent claim is included for an inspection system as for testing a battery.
