[0003] However, most of the battery temperature measurement systems in the traditional energy storage industry use NTC thermistor effect temperature measurement, which has low sensitivity and is easily disturbed. The existing BMS temperature measurement system uses NTC temperature measurement, which has low sensitivity and is not resistant to corrosion and susceptible to Electromagnetic interference; while the existing FBG temperature measurement systems on the market are often expensive, large in size, and the non-mainstream chip of the main control chip has poor open source and portability, and is inconvenient to integrate with the existing BMS system. In view of the above situation, in Technical innovation based on existing temperature measurement methods

Description
technical field [0001] The invention relates to the technical field of temperature measurement methods, in particular to an FBG temperature measurement method suitable for energy storage batteries. Background technique [0002] FBG sensor is a hot spot in the field of optical fiber sensing in recent years. It has the advantages of no electromagnetic interference, high insulation performance, good explosion-proof performance, and corrosion resistance. [0003] However, most of the battery temperature measurement systems in the traditional energy storage industry use NTC thermistor effect temperature measurement, which has low sensitivity and is easily disturbed. The existing BMS temperature measurement system uses NTC temperature measurement, which has low sensitivity and is not resistant to corrosion and susceptible to Electromagnetic interference; while the existing FBG temperature measurement systems on the market are often expensive, large in size, and the non-mainstream ...
