The present invention provides a device and method for sealing detection of batteries in battery pack and a related device. The device for sealing detection of batteries (10; 10') in a battery pack comprises: a detection device configured to detect (215) the first measurement value of the parameters of the batteries (10; 10') in the battery pack, the parameters consisting of the quality, the volume, the size or the thickness of the batteries (10; 10') in the battery pack, and configured to detect (255) the second measurement value of the parameters of the batteries (10; 10') in the battery pack; a comparison device configured to compare (265) the second measurement value and the first measurement value; and a determination device configured to perform determination (270) when the distinction of the second measurement value and the first measurement value is larger than a pre-determined threshold value (265.1), the batteries (10; 10') in the battery pack being not sealed, or configured to perform determination (275) when the distinction of the second measurement value and the first measurement value is smaller than a pre-determined threshold value (265.2), the batteries (10; 10') in the battery pack being sealed.
Description
technical field [0001] The invention relates to a device and a method for leak checking of battery cells as well as a computer program, a computer program product, a battery cell, a battery module, a battery, a battery system and a vehicle. Background technique [0002] It is foreseeable that not only in stationary applications, such as in wind power plants, but also in mobile applications, such as in electric vehicles (electric vehicles, EV), hybrid electric vehicles (hybrid electric vehicles, HEV) or plug-in hybrid electric vehicles (plug-inhybrid electric vehicles) , PHEV), new battery systems, for example with lithium-ion accumulators, are increasingly used as rechargeable electrical energy stores (EES, electrochemical storage system (electrochemical storage system), EES). [0003] The battery system must meet very high requirements regarding usable energy content, charging / discharging efficiency, reliability, lifetime and tolerable capacity loss, for example by frequent...
