Embodiment Construction

[0040] Figures 1-3 illustrate how to use a gas store in a battery pack or a battery pack. These examples preferably relate to the application of the invention for monitoring batteries in electronic products.

[0041]Fig. 1 is a layout diagram of the first embodiment. The gas sensor 13 is installed in the battery case 12 or a battery pack. As soon as the battery 11 begins to leak chemicals, the volatile species diffuses to the location of the sensor 13 and triggers a sensor signal 14 . This signal is used by the safety management system 15 to provide, for example, a message to the product user and / or initiate a safe shutdown operation. The safety management system 15 may utilize an intranet or Internet connection to remotely send or receive sensor signals or provide information regarding battery status. In order to minimize air circulation within the battery compartment 12 to ensure reliable detection of a leaking battery 11, the battery housing 12 is preferably closed or ev...

Abstract

Battery leakage detection system comprising a gas sensor having a gas sensitive nanoparticle structure.

Description

technical field [0001] The present invention relates to a system for detecting chemical leakage in batteries. Background technique [0002] Portable electronic devices such as computers, mobile phones and audio / video devices use non-rechargeable primary batteries or rechargeable secondary batteries as power sources. The battery cells used in rechargeable batteries, especially lithium-ion battery cells, contain hazardous chemicals that can be very dangerous to the user if the battery casing leaks. Battery cell leakage like this can be caused by material aging, but also if the battery is subjected to excessive environmental changes such as temperature swings. Many efforts have been made to ensure the safe handling and use of battery pack cells. [0003] For example, secondary batteries are often incorporated into battery packs. Efforts have been made to construct cell and battery pack housings as well as possible in order to avoid serious damage to the host device from chem...
