Abstract: A rechargeable battery short-circuit early detection device that detects a short-circuit in a rechargeable battery includes one or more processors connected to a current sensor that detects a charging current of the rechargeable battery, wherein the one or more processors are programmed to: if a detected temporal slope of the charging current exceeds a first threshold, determine that there is a possibility that a short circuit has occurred in at least one of the cells; detect anew a temporal slope of the charging current after a prescribed period of time has elapsed since the determination of said possibility; and thereafter, if the anew detected temporal slope of the charging current exceeds a second threshold that is greater than the first threshold, determine that there is a possibility that the short-circuit is progressing, and output a signal indicating said possibility.

Abstract: A feeding fiber cable collectively extracts laser light generated by each of a plurality of fiber laser engines. A processing head converges and emits laser light to a workpiece. A process fiber cable transmits the laser light extracted by the feeding fiber cable to the processing head. The core diameter of the feeding fiber cable and that of the process fiber cable are equal and 50 μm. The plurality of fiber laser engines each have a filter that reduces a value of Raman scattered light in the laser light.
