Abstract
Official abstract text for this publication.
A system is disclosed for protection of a lithium ion battery. The system includes a first light source and a first optical guide including first and second ends. The first optical guide is in optical communication with the light source at the first end of the first optical guide. A first material is disposed on an exterior surface of the first optical guide in fluid communication with an exterior surface of the lithium ion battery. The first material is optically responsive to a first gas indicative of an overheat condition or combustion of the lithium ion battery. A first light detector is in optical communication with the second end of the first optical guide.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making a system for protection of a lithium ion battery, comprising: disposing a first optical guide including first and second ends and a first material optically responsive to a first gas indicative of an overheat condition or combustion of the lithium ion battery on an exterior surface of the first optical guide, with the first material in fluid communication with an exterior surface of the lithium battery; disposing a first light source in optical communication with the first end of the first optical guide; and disposing a first light detector in optical communication with the second end of the first optical guide; wherein the first optical guide, the light source, and the first light detector are installed as a retrofit to an operational lithium battery connected to a power sink and a recharging power source. 2. The method of claim 1 , wherein the lithium ion battery and the first material on the exterior surface of the first optical guide are disposed within a housing. 3. The method of claim 1 , further comprising: disposing a second optical guide including first and second ends and a second material optically responsive to a second gas indicative of an overheat condition or combustion of the lithium ion battery on an exterior surface of the second optical guide, with the second material in fluid communication with an exterior surface of the lithium battery; disposing the first light source or a second light source in optical communication with the first end of the second optical guide; and disposing a second light detector in optical communication with the second end of the second optical guide.
