Abstract

The invention discloses an apparatus for detecting a battery pack, a method, a battery, a battery system and a vehicle. The apparatus for detecting a battery pack is characterized in that: a processing mechanism which controls the apparatus and processes signals; an excitement mechanism which generates an excitement signal directed at the battery pack and is connected to the processing mechanism; an acquisition mechanism which acquires a response signal of the battery pack and is connected to the processing mechanism, wherein the excitement mechanism is connected to a joint of the battery pack such that the battery pack can receives the excitement signal via the joint, and the the excitement signal of the battery pack generates the response signal, and one type of defect position of the battery pack effects the response signal via allocation or generation of heat, and the processing mechanism detects the defect position via the response signal. And the invention relates to a method for detecting the battery pack, a battery pack, a battery, a battery system, a vehicle, a computer program and a computer program product.

Description

technical field [0001] The invention relates to a device and a method for testing a battery assembly as well as batteries, battery systems and vehicles. Background technique [0002] It can be seen that not only stationary applications, such as wind power plants, but also mobile applications, such as electric vehicles (electric vehicles, EV) or hybrid vehicles (hybrid electric vehicles, HEV), for example have More and more new battery systems of lithium-ion batteries, lithium-polymer batteries or nickel-metal hydride batteries are being used as rechargeable electrical energy stores (EES). [0003] The battery system has to meet high demands with regard to usable energy content, charging / discharging efficiency, reliability, lifetime and undesired loss of capacity due to frequent partial discharges. In addition, battery systems must meet high safety requirements and comply with strict legal regulations. [0004] A battery system includes a plurality of battery cells. The ba...
