Title:
ENERGY STORAGE DEVICE CHARGING STATE FIBER ONLINE MONITORING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/196193
Kind Code:
A1
Abstract:
An energy storage device charging state fiber online monitoring system and method. The system comprises a light source (1), a polarizer (2), a polarization controller (3), a fiber circulator (4), a fiber sensor probe (5), an electrochemical supercapacitor device (6), a fiber optical spectrometer (7), and an electrochemical workstation (8). The light source (1), the polarizer (2), the polarization controller (3), the fiber circulator (4), and the fiber sensor probe (5) are sequentially connected. The fiber optical spectrometer (7) is connected to the fiber circulator (4). The electrochemical supercapacitor device (6) is connected to the electrochemical workstation (8). The fiber sensor probe (5) is disposed in the electrochemical supercapacitor device (6). The fiber sensor probe (5) can transmit an optical signal, can also act as a sensing probe to obtain light wave information, thereby performing in-situ monitoring on the magnitude of the potential of a supercapacitor during a charging/discharging process in real time and storing electric quantity information in real time, can be implanted in a small space to implement in-situ measurement, and can also simultaneously measure changes of multiple parameters in real time, such as a charge state, the potential, temperature, and other information.
