Application: Temperature measurement apparatus for battery cell and method therefor (Patent ID: US20240055678A1)
The patent filed by LS Electric Co Ltd describes a temperature measurement apparatus for battery cells. The apparatus includes a light collecting unit, a light receiver, and a control unit. The light collecting unit collects electromagnetic waves radiated from the battery cell, the light receiver receives these waves, and the control unit measures the temperature of the battery cell based on the received electromagnetic waves. The apparatus can measure the temperature of a partial area of the battery cell's surface, providing a non-intrusive and efficient method for temperature monitoring.
The patent claims detail the specific components and configurations of the temperature measurement apparatus, including the use of a light collector with a light guide plate and reflective member, a light receiver with light receiving sensors, and a Fresnel lens for concentrating the electromagnetic waves. The apparatus can measure the temperature of multiple battery cells, acquire temperature spectrum information, and detect heat generation based on wavelength intensity. The design of the light collector and receiver is optimized for accurate temperature measurement, with the Fresnel lens positioned close to the battery cell and the light receiving sensors strategically placed for effective detection. Overall, the patent outlines a comprehensive and innovative approach to temperature monitoring in battery cells using electromagnetic wave collection and analysis.
