Abstract

The invention relates to a battery temperature sensor. The battery temperature sensor includes a ring-shaped fiber which is provided with a fiber grating thereon. The ring-shaped fiber is fixed to thesurface of a battery monomer through a soft fixing assembly. The battery temperature sensor herein also includes a temperature measurement apparatus. The ring-shaped fiber and the temperature measurement apparatus are connected. The technical solution has the following beneficial advantages: the ring-shaped fiber is provided with a fiber grating thereon, and the fiber grating is fixed to the surface of the battery monomer through the soft fixing assembly, which reduces the size of an apparatus and makes packaging much simpler. In addition, the battery temperature sensors can be easily installed in respective battery monomers inside a battery box, can independently monitor the temperature of respective battery monomers, and can monitor the temperature of respective batteries inside the battery box in a differentiated manner.

Description

technical field [0001] The invention relates to the field of optical fiber technology and the field of measurement technology, in particular to a battery temperature sensor. Background technique [0002] With the widespread application of electric vehicles, people's requirements for battery safety are getting higher and higher. As a parameter to measure the state of the battery, temperature is an important monitoring object for battery safety. Traditional temperature sensors have problems such as large size and complex packaging. Due to this limitation, the existing technology can only monitor the overall temperature of the battery box, and cannot monitor the differential temperature of a single battery. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention proposes a battery temperature sensor, which has the advantages of small size and simple packaging, and is convenient to be installed on each b...
